As a parent, you know it is your responsibility to make sure that your child is properly taken care of at all times. In fact, you might only trust yourself when it comes to making sure that your little one is fed, played with and watched during the day, but the truth is, you probably can’t watch your child all the time. You might have to go back to work, which means you will have to make other childcare arrangements during the day. Even if you are a stay-at-home parent, you might need the help of a nanny so that you can get household chores and errands done and so that you will have a bit of time for yourself. Regardless of your reason for hiring a nanny, you need to keep a few things in mind in order to keep your child safe while he or she is under someone else’s care.

The truth is that you never really know how reliable and trustworthy a nanny is until you give him or her a chance. Running a background check and interviewing your nanny can help you weed out some of the bad potential candidates, but it doesn’t guarantee that you will end up with a nanny who you can truly trust to take good care of your little one. Therefore, you should consider taking a few extra precautions in order to protect your child and check on your nanny. For instance, you might want to consider installing a hidden nanny cam so that you can keep an eye on what is going on while your nanny is taking care of your child. This can help you watch out for bad behaviors, and it can make you feel better about leaving your little one in the care of someone else.

Understand the Importance of a Nanny Cam

Many people feel as if parents who install hidden nanny cams in their homes are overreacting. There are a lot of great nannies out there who don’t need to be watched on nanny cams, and you will hopefully find that your nanny is this way. However, you never really know if you can trust someone until you have found out what he or she is like yourself. Without a nanny cam, you might always find yourself wondering if your nanny is a trustworthy individual who is taking good care of your child. If you have a nanny cam, however, you don’t have to worry; you will have the proof right in front of you, and you can use this video evidence to ensure that your child is being properly taken care of.

Make Sure Your Nanny is Doing His or Her Job

If you are paying your nanny your hard-earned money, you want to make sure you are getting your money’s worth out of the deal. Not only do you want to make sure that you aren’t paying your nanny to slack off, but having a hidden nanny cam can also help ensure that your child is being properly cared for during the day. If you have a hidden nanny cam in place, you can make sure your child is being fed, changed, played with and properly cared for while you aren’t around. If you ask your nanny to take on other responsibilities as well, such as cleaning up around the house or doing other chores, you can also use your nanny cam to make sure that these things are being done during the day. This is a great way to find out whether or not your nanny is a hard-working individual who is willing to do his or her job correctly, and it will also help you feel better about knowing whether or not your child is being fed and cared for in a timely manner when he or she is under the care of your nanny.

Watch Out for Theft

Since you are inviting your nanny into your home, you are trusting him or her around all of your family’s belongings. Although you can always lock up jewelry, money and valuables in a safe, it is impossible to lock up everything in your home every time that your nanny is around. Although you might not want to think about it, there is always the possibility that your nanny could try to stuff a few things in his or her pocket while watching your child. Since you obviously probably cannot afford to give your things away to your nanny, you will need to do what you can to make sure your items are safe while your nanny is in your home.

Although it might seem easier to give your nanny the benefit of the doubt until something turns up missing, you don’t want to wait until it is too late to find out your nanny is a thief. Along with protecting you from losing things to your nanny without knowing about it, a hidden nanny camera can also protect your nanny. If something is missing, you might automatically think that your nanny took it. If this wasn’t the case, however, your hidden nanny cam can help protect your nanny from being blamed for something that he or she didn’t do as well.

Ensure That Your Household Rules Are Being Followed

Not only do you have to worry about the safety of your child, but you also have to make sure that your household rules are being followed. For instance, you may have told your nanny that you did not want him or her inviting anyone over while you are not home. You might still wonder if your nanny is following this rule when you aren’t around, however, and you could find yourself worrying about the situation while the nanny is in your home. If you have a hidden nanny cam in place, however, you will be able to monitor to make sure that your nanny is following all of the rules that you expect to be followed in your household.

Keep Your Child Safe

Unfortunately, there are a lot of bad things that can happen to a child if he or she is under the care of a nanny that you can’t trust. There are some people out there who aren’t really meant to take care of children, and some of these individuals can have quick, bad tempers; this could allow these individuals to act in an inappropriate way. It is important for you to know about this behavior if it occurs so that you can put a stop to it right away, but it might be difficult for you to know if your nanny is yelling at or hitting your child when you aren’t home. You don’t want to wait until things escalate before you find out whether or not your nanny is handling situations inappropriately around your child, but this could happen if you don’t take the proper security precautions. Fortunately, however, a hidden nanny cam can help clue you in to this type of behavior right away, meaning that your hidden nanny cam can actually help you keep your child safe.

Physical abuse isn’t the only type of harm that you have to look out for when your child is under the care of a nanny. Unfortunately, there is always the possibility of sexual abuse; although this isn’t a pleasant thing to think about when it comes to your child, your child could face a lot of danger if you don’t know to watch out for this behavior. If you have a nanny cam in place and watch your footage regularly, however, you can catch this behavior as soon as it starts. Your camera can also help you watch out for signs of emotional or mental abuse as well. Since all of these things can be seriously detrimental to your little one, you owe it to your child to keep an eye out for this type of behavior. Fortunately, a hidden nanny cam is one of the most effective ways of catching bad behavior from nannies, and it can help you fix an unpleasant or dangerous situation as soon as possible.

Get Reassurance

Although you are probably thinking about installing a nanny cam so that you can look out for bad behavior from your nanny or babysitter, you have to realize that a nanny cam can also provide you with a positive experience. If you end up with a hard-working nanny who doesn’t steal, break rules or mistreat your child, you should know about it. A hidden nanny cam can help you realize that you have chosen the right person to take care of your child; this can provide you with reassurance, and it can also give you the opportunity to commend your nanny for being such a hard-working and caring caretaker for your little one. This can benefit you and your family as well as your nanny, and it will let you know that you don’t have to continue your search for the perfect caretaker for your child any longer.

Have the Evidence You Need

In the event that something does go wrong in your household, you will need evidence in order to do anything about it. If you have video surveillance footage of your nanny stealing from you or harming your child, you might have the evidence that you need in order to approach your local law enforcement agents and district attorneys. This evidence can help you press charges, and it can help ensure that you recover your stolen belongings or that your nanny pays the consequences for the crimes that he or she has committed against you or your child in your home.

Even if you don’t use your evidence to go to the police about a situation, it can be a good thing to have video evidence when you approach your nanny about his or her behavior. If your nanny has done something serious, you can use your surveillance footage to prove to him or her that you know what he or she has been up to, and it gives you a good reason to fire the individual. If you decide to keep your nanny after an infraction, you can still use your video surveillance footage to approach the individual about the situation at hand.

Install Your Nanny Cam for An Affordable Price

As you can see, there are a lot of benefits to having a nanny cam in place if you count on a babysitter or nanny to take care of your child. Since you probably realize that installing a nanny cam is important, you might be wondering how much money you will have to shell out in order to install a nanny cam in your home. Fortunately, there are affordable models that will fit into almost any budget, and there are also nicer systems that can help you have more control over the monitoring and surveillance of your home while your nanny is there.

You can always install a single nanny cam in your nursery or child’s bedroom if you are on a budget but still want to keep an eye on your child. There are a lot of small units out there, and many of them come with a monitor that will allow you to watch the footage; others can be used to stream the footage to your laptop, desktop PC or even your smartphone. This can allow you to watch footage from wherever you are, which can be great if you are at work during the day and feel a little worried about your child.

If you want to keep a closer eye on your nanny, you can install multiple cameras in your home. There are a lot of great systems that are easy to install; simply talk to a security professional about your needs, and he or she will help you find the right hidden nanny cam and accompanying system for you and your family’s needs.


The Best Security Cameras for Your Start Up Business

Written By:

Protecting your business from theft is an important part of being a business owner. Many companies use security cameras to monitor employees and guard against theft. There are a variety of security cameras available and the kind you choose will depend on your needs. The first step is to decide how much security protection you need for your business. Do you want to monitor all hallways, inventory rooms and entry points? If so, you will need a security camera system that can accommodate multiple cameras and has large storage capabilities for recording.

Motion Sensitive Cameras

These cameras are a good choice when you only want to capture images when the camera detects movement. This type of camera system does not need a lot of storage. These cameras are triggered by sensing heat. If you want to monitor the entry points into your business, these cameras are a good choice. You can also choose a camera with night vision. When the camera senses low-light conditions, the night vision starts recording. This is a great way to monitor your business at night. Motion sensitive cameras with night vision are available from many security camera manufacturers. You can also consult with a professional security company to choose the right camera for your business. Correct camera placement is an important part of any security system. The camera’s sensitivity can be adjusted to accommodate varying business security needs.

Common Types Of Security Cameras

There are several common types of security cameras available on the market. Does your business need a camera shaped like a bullet or dome? There are advantages to these types of cameras. A security camera that is shaped like a bullet is a common type of camera. They are used most often when you want the security camera to be seen. However, a dome shaped camera is meant to be hidden. The domed security camera hides the angle of the camera from viewers. These are often used to shopping malls, banks and retail locations. If you want your security cameras to be seen by employees and others, then choose bullet shaped security cameras. Bullet cameras are often mounted on the wall or ceiling or at entry points. Hidden security cameras can be used to detect theft in inventory rooms or cash registers. These cameras are not meant to be detected and are often used by businesses to detect theft.

Advantages Of Security Cameras At Work

There are many advantages to installing security cameras to monitor activity. Theft can happen at any time and having the capability to record the event is a great advantage. You can offer proof to law enforcement, insurance companies or others should there be an incident at your business. Monitoring your business with security cameras can also reduce the risk of company property theft. If employees know there are security cameras present, then productivity can be improved. New technologies have improved the images that are produced and the costs have been lowered. When you compare the cost of a new security system versus the cost of theft, the security system is a good investment.

Infrared Security Cameras

Infrared security cameras capture colored images when there is sufficient light available. When the camera detects low-light conditions, the images are produced in black and white. These cameras will not produce an image when there is no light at all. The security camera must be equipped with night vision in order to produce an image. Infrared security cameras are useful when there are low-light conditions such as those found inside a business at night. If you want to monitor the entry points of your business at night, be sure the camera system you choose is equipped with night vision.

Where To Place Your Security Cameras

There are specific areas where security cameras can be installed to enhance security at your business. The entrances and exits to the building are an important area to monitor. You should develop a system where visitors must sign in when they visit your company. The cameras should have a clear line of sight at the entry point. The exits are an equally important location for security cameras because they give a clear indication of who leaves the building. Security cameras placed inside the warehouse where you store business supplies and equipment is another important area that needs to be monitored. If your business conducts customer transactions, then this would be another key area for camera placement. Place security cameras outside of your business that captures the parking lot. This is an important area in case of vandalism. You will be able to capture images of anyone lurking in the parking lot after business hours.

IP Security Cameras

Internet Protocol security cameras are also known as IP cameras. These cameras allow you to record images and view them from anywhere that has an Internet connection. The main advantage is convenience of viewing. You could install IP cameras in your business and monitor the images from your smartphone or computer. If you are out of town, you can keep an eye on the office from almost anywhere. These cameras are affordable and easy to install. Start-up businesses are often on a tight budget, and purchasing a security system with IP cameras is an affordable option. IP cameras offer clear images and peace of mind. You can choose to view live or recorded images. Consider hiring a security professional to come to your business and do a security audit. These audits are a perfect way to find possible security flaws that may exist. An experienced professional auditor will walk through your business and make recommendations about security cameras and systems.

Wired Versus Wireless Security Systems

Choosing between wired and wireless security systems is a matter of understanding the advantages and disadvantages of each type of security system. A wireless security system is easy to install but the system can pick up interference from other wireless devices. A wired security system is harder to install, but it is not affected by interference from other sources. Wireless security systems usually cost more than wireless security systems. The main advantage of wireless security systems is the ease of installation. Seek professional installation to ensure your security system works properly. Even a wireless system can be installed wrong if you are not familiar with security camera installation techniques.

Intrusion Alarms

An alarm system should be combined with surveillance cameras to enhance the security to your business. An audible alarm can frighten away an intruder. These alarm systems can be installed to sound an alarm on the outside of your business as well as the inside. This is a great way to alert the community or anyone that passes by that your business is at risk of theft. A monitored alarm system is best in order for law enforcement to be summoned immediately. A professional alarm company will place security sensors on doors and windows to prevent access into your building. If any of these areas are tripped, then the alarm company receives the signal. You can also set the system up to contact you at the same time as law enforcement. The combination of an alarm system and surveillance cameras will give you a high level of security protection at your business. Consult a professional security company to get started.

Vault And Safe Systems

Another way to protect your business is to have a vault or safe installed. This will add an additional layer of security to your existing security plan. Place cash and important papers inside your safe when the business closes. Make sure the safe is hidden from plain sight. Your cash and important papers will be protected until you return to work. A fireproof safe is the best protection against theft or fire. A high-quality safe will have a sturdy lock that makes tampering almost impossible. A professional security company can advise you on the different types of vaults and safes that are made for businesses.

Access Control Systems

Controlling the access into your business during normal business hours is an important way to reduce security risks. You can control this access by using an electronic card system or intercom entry systems. Combined with a surveillance system this can be an effective security solution. An electronic card system can be accessed from any computer to receive valuable data. These systems will tell you the times of entry or exit, and the identification of whomever accessed the building. This is important information if you have an incident of theft. An intercom system can also be an effective way to control access into your building. Intercom entry systems can be combined with a surveillance camera to give you a view of the visitor. Controlling access into the building will also improve security for employees. These systems are capable of producing audio and visual communication. Some companies simply restrict visitors into their facilities by a visitor sign in method. This method is not as secure as the locked door and access control methods.

Adequate Lighting

A business that is well-lit at night is a deterrent for many potential thieves. The lights in most businesses make up the largest part of a company’s energy bills. Solar lights with motion detection capabilities is a great way to light up the outside of your business without spending a lot of money. Make sure the entry and exit points are lit with bright lights. Motion detecting lights work by sensing movement and heat. Solar energy lights are a good investment because they will pay for themselves after a short amount of time. The inside of your business should be dimly lit at night with surveillance cameras monitoring the business at all times. Some companies hire a professional security company to monitor their surveillance cameras at night. The security methods you choose will largely depend on your security budget.

Employee Safety

Ensuring that employees are safe is the responsibility of all business owners. Security in the workplace requires creating a good security plan. Employee security involves protecting employees from possible harm through other employees, job safety training and fire or weather-related emergencies. All employees should know and understand the company’s security plans in the event of an emergency situation. Fire sensors, surveillance cameras and employee background checks combine to produce a safer work environment. Develop a security plan by contacting a professional security company for help and guidance. The types of security you choose will depend on the type of business you own and the company’s security budget. Background checks on all employees can prevent some potential problems but they are only a part of a good security plan.

Additional Business Security Tips

Security in the workplace does not end with surveillance cameras and equipment. There are other security methods that should be in place that include computer, customer data privacy issues and regular security audits. Computer security techniques include virus protection and controlling access to sensitive company and customer data. Privacy laws require businesses to protect the privacy of their customers. This includes protecting credit card numbers, addresses and other sensitive customer information. Businesses also need to limit access to sensitive company information such as financial information. Hiring a computer security expert to create a data security program for your business is the best way to ensure your data is secure. Depending on your budget, you could hire a computer expert on a full-time or contract-only basis. Computer security experts can help you identify your company’s security needs. Limiting employee access to certain areas on the computer will improve the level of security in your business. Security in the workplace requires a great deal of planning in all areas. Hiring a security expert to conduct regular security audits will help you identify your company’s security needs. Contacting a professional security company is the first step to developing a security plan for your business. These experienced professionals will work with you to create a security plan for your unique business. Improving security at work can give you peace of mind.

Best Rated Home Security Camera

Many people never assume they will ever have to worry about purchasing a security system for their home or business. The problem is you never know when something is going to go wrong, which is why it is important to be prepared for the inevitable. If you are in the market for a home security system, numerous options are available from which you can choose. To help guide you in the process, look at the following steps to ensure you are making the best choice possible.


Choose the perfect spot for your surveillance system. Location plays a large role in choosing the appropriate type of security camera for your needs. Depending on whether your camera is going inside or outside of your home, you will need a security camera that works accordingly. When you use a security camera on the outside of your home, you will want something that is resistant to vandalism. The last thing you want is a security system that goes down because you don’t have the proper equipment and preventative measures in place. Weatherproof cameras are another factor to consider when you are placing a camera outside of your home.


For those who are placing their security camera in one location, a wired camera may be ideal. If you never plan to move your camera from one location to another, wired cameras are perfect. You can place them right where you want them and never have to worry about maneuvering anything later on.


If you are going to need the signals from your camera sent through floors and walls, you will want to consider a wireless camera. When you have a wireless camera in your home or business, you have the option of moving the camera from one location to another without having to run a number of wires each time you relocate your camera.


If you are ever stuck without power, you will want a camera that can work without power. Battery-operated cameras are perfect for covering you in any type of power situation. These cameras also don’t have a bunch of wires dangling from them, which makes them perfect for concealing in a number of different locations.

Reviews are Important

Look at the various reviews of home security cameras to help determine which one is best suited to meet your needs. Magazines and online sources help provide you with the information you need without having to worry about any biased opinions. Consumer Reports is an excellent choice for finding information about various cameras. They do not accept money or goods from the companies whose products they test. It is important to have a review that is not biased. Purchasing a product based on false information will only create more issues down the line for you. You should have accurate and honest information about the items you are purchasing.

Online Forums

For those who are Internet savvy, plenty of forums will provide you with information before you purchase a home surveillance system. You will be able to chat with other individuals who have already purchased and used the item you are thinking about purchasing. Getting information from real consumers with real opinions about products means you are going to get all of the information your desire, regardless of whether that information is positive or negative.

Getting the Best Deal

When investing your hard-earned money into something such as a security camera, you want to ensure you are not paying any more than what you should. Many companies will try to make you spend a lot more than necessary, which is why you need a reputable company that knows what you need for your home or business. As you choose which camera to purchase, make sure you understand the warranties on each item. Depending on the manufacturer, you will be able to get some amazing deals on the product and an extensive warranty.

The Best Security Camera for Your Home

A security camera is an excellent way to help boost the security of your home. Beyond being able to provide constant surveillance for your home throughout the evening and daytime, these cameras are able to capture an extensive amount of detail when a security breach occurs inside of your home. Due to all of the changing technology, you can choose from a wide variety of different security cameras for you to purchase.

Wireless Security Systems

When you use a wireless security camera, you won’t have to worry about any wiring whatsoever. Not only are these cameras easy to mount, but they are portable as well. You will be able to change their location in no time at all. These cameras send their surveillance footage using a wireless receiver. All of the transmissions are sent into a computer monitor for you to view while the footage is happening or later on after you have recorded it all.

Covert Cameras

A covert camera is similar to something you would be able to find inside of your home. Everything from teddy bears to dolls and other home décor items can have a covert camera inside of them. Most of these cameras will go unnoticed, which proves to be an exceptional advantage when it comes to your home security system.

Infrared Cameras

When you have an area that is dimly lit, you can use an infrared camera to help give you the level of surveillance you desire. They work to help detect body heat being emitted from an individual in the line of surveillance. The areas of the body that have the most body heat emissions will display as brightly colored regions on the camera. These cameras will record any movement that occurs and help to capture the motion clearly. You have the option of setting one of these cameras up inside of your garage or other area with low lighting conditions.

Night Vision Cameras

Night vision cameras are utilized in darker areas. They are great for providing you with the surveillance you need during the nighttime hours. The images these cameras produce are typically black and white. Due to their mode of output, they are able to provide you with a clearer figure than most of the other cameras on the market today. Outdoor surveillance will be able to make the most out of these cameras.

Determining Whether Wireless Cameras are the Best for Your Home

Everyone thinks about the safety of their home at one point in time or another, especially when you have a family to think about on the inside. When you are making the choice for a security camera in your home, you will want to determine whether wired or wireless is going to work the best for your home. As you prepare to make that decision, use some of the following tips to help you out along the way.

•    Determine the best location for your security camera to be installed. You also need to choose how it is that you want to use your system. When it comes to installing a wireless security system, there are a few things that you need to determine before making the final decision on what to purchase.

•    The last thing you want to do is draw attention to all of the wires for your security camera. When the perpetrator is able to identify where the camera is at and how to disable it, the camera is not going to do you very much good. One of the best things you can do is to keep your security camera as inconspicuous as possible to maximize your security system.

•    If you have a mobile device, you will be able to rotate the location of your device. You won’t have to worry about a camera that is stuck in one location. For those who notice one area is not getting enough coverage, you are able to take your mobile camera and place it somewhere else to help capture any activity around your home.

•    When you have a wireless camera, you are able to take it with you wherever you go. If you decide to move into a different house, you will not have to worry about buying a new camera for your new home. For those who have a wired security camera, the camera will not be able to relocate as easily. You will end up having to purchase a new camera for your new property.

•    For those who want the ability to transmit signals through walls and floors, the wireless camera is ideal. You won’t have to worry about being restricted to where you can use your camera because of any interference.

•    If you want a camera that is capable of quickly transmitting surveillance footage to your computer, television or VCR, the wireless cameras are essential. When it comes time to transferring footage to catch the perpetrator, you need something that works quickly and efficiently.

•    If you are searching for a way to hide the camera out of sight for any potential intruders, a miniature wireless camera is ideal. You can tuck them away inside of a book, stuffed animal or any other household item.

Security Camera Jargon and Acronyms Deciphered

Security Camera Jargon and Acronyms DecipheredCCTV (Closed Circuit Television): This term once referred specifically to systems that worked like standard television.  At the time that the term was coined (the 1960s), the cutting edge was technology that was to eventually become cable television.  It used low-frequency waves sent over metal-core and braid cables to connect a video signal with a receiver.  However, instead broadcasting in a way that anyone could receive it (also called Open Circuit Television) it would instead only be connected to a single source (thus “closing” the circuit).  Today the term is still applicable.  All security systems connect from the camera to a recorder.  Even though theoretically anyone can “connect” to the signal over the internet, you are still required to have the username and password…  This effectively allows the system to prevent anyone who does not belong from “joining” or “connecting” to the signals, and therefore “closes” the circuit off again.

DVR (Digital Video Recorder): This is a term used for all recorders that use a digital format to store video.  You can find some that record your cable TV, some that record cameras, and some that record broadcast video information.  In context with security, it refers to all recorders that receive information through an analogue broadcast.

NVR (Network Video Recorder): This term is a little more specific.  It refers to any video recorder that connects to a computer network to receive and store video information.  The video information can come from literally any source including cameras, other recorders, computer storage, and any device enabled to send video in a format the NVR recognizes.

RF (Radio Frequency): This is a term that is used to describe any and all transmissions of information, data, video, audio, etc via an audio or video signal.  It is a signal that can be detected by human style audible perception (like terrestrial FM radio).

BNC (Bayonet Neill–Concelman) Connector: This is a standard connector used in RF (Radio Frequency) transmission of all types.  It’s named after the two successful inventors that first created it to simplify the joining of two RF circuits.

RCA (Radio Corporation of America) Connector: Once of the most venerable connectors used today.  It was introduced by its namesake in the 1940’s to carry audio signal from turntables to amplifiers.  A use that it is still used for today.

RG59 or 6 (Radio Guide): The Radio guide is the US Military’s Guide to cables.  The number refers to the order the cable was added to the guide, not the qualities of the cable.

RJ-232, 45, 6 (Registered Jack): This system was created by the FCC (Federal Communications Commission) to regulate and standardize the technology being developed in the communications industry.  The number is relevant to the order that the configurations of wires were added to the list.

Cat3,4,5,6,7 (Category): This term refers to a rating of cable that is composed of 4 pairs of wire that have been twisted.  As the “Cat” number increases, so does the speed at which the cable is capable of transferring data.  Several changes factor into the rating/speed increase.  All of these changes are determined in the manufacturing process of the cable.

1.3 Megapixel IP Indoor/Outdoor IR Dome Network Security Camera

IP (Internet Protocol): This refers to anything “network” oriented.  For example; a security camera that connects to a computer network is referred to as a “IP Camera”.  Many devices are joining the ranks of “IP” including Printers, Security Systems, Sprinkler Systems, Coffee Makers, etc.  As demand increases for “Home Automation”, we’ll find almost every device in our lives assigned to an IP address and remote controllable from our smart phones.

CCD (Closed Coupled Device): This is one of the two most popular types of light-sensing chips in cameras today.  It translates light frequencies into a signal usable by a DSP.  It is regarded to be the superior chip for poor lighting conditions.

CMOS (Complimentory Metal-Oxide Semi-Conductor): This is one of the two most popular types of light-sensing chips in cameras today.  It translates light frequencies into a signal usable by a D

SP.  It is regarded to be the superior chip for high resolution requirements.

DSP (Digital Signal Processor): DSPs are the chip “core” of any computerized video process.  Essentially the brains and tools for a camera, this chip receives signal from a CMOS or CCD sensor and translates it into a digital format that can be transmitted, compressed, and stored for retrieval at a later time.

GUI (Graphic User Interface): This refers to any software that allows a user to interact with hardware using a video display and devices like a mouse, keyboard, joystick, trackball, or other device.

NTSC (National Television System Committee): This is the format of “standard” television broadcasting created to allow broadcast stations to be available on many different brands and types of televisions.  It governs the number of lines and frame a picture is composed of and the general resolution of the picture as well. It is used throughout the Americas and parts of Asia.

PAL (Phase Altering Line): Similar to NTSC, this is the format of “standard” television broadcasting that is accepted throughout the rest of the world where NTSC is not used.

 630TVL Weatherproof Day/Night Infrared Bullet Camera IR (Infrared): Often misunderstood, Infrared is actually a color.  All colors are created by changing the frequency of a beam of white light that is bounced off of an object. The frequency of I

R is not detectable by the human eye.  In the application of IR in CCTV, simply think of theatrical lighting.  If the stage lights are fitted with blue filters and then turned on; everything on the stage appears to be blue.  This is exactly how IR works.  The lights fitted on cameras emit IR colored light.  Thus making objects in front of the camera appear to be “IR colored”.  If your camera is able to detect IR light, it will translate the IR color to black and white (colors we can see).  The simple truth is, its simply doing the same thing as stage lights.  We simply can’t see the color.

HAD (Hole Accumulation Diode): A technology created by the Sony corporation designed to reduce the distortion created by the absence of sufficient light coming in contact with the imaging sensor.  It essentially increases low light capabilities.

OSD (On Screen Display): Many cameras have menus to adjust their behavior.  These are often set by making selections from a joystick or external control.  The menus that pop up when actuated are referred to as the “OSD”.

WDR (Wide Dynamic Range): A feature very important to any application where light and dark zones are simultaneously in the field of view of the camera.  The is a digital enhancement that allows the digital iris of a camera to overlap over and underexposed images to provide a single usable picture.  It helps compensate for glare and dim areas in images.

ATR (Automatic Tone Reproduction): Another feature for compensating for glare and underexposure.  However, unlike WDR, its an enhancement in the DSP, not a compensation of the CCD’s digital iris.  Its literally a higher sensitivity to small details of information coming in from the CCD.  This version is typically great outdoors, but WDR is often superior inside.

PTZ (Pan Tilt Zoom): These are the three typical ways that a camera can be motorized.  Some cameras may have on 1 or 2 of these adjustable axis, while cameras with all three are becoming increasingly more common.

ONVIF (Open Network Video Interface Forum): Not all IP-Video devices can talk to each other.  Essentially they all operate and are programmed in different way.  The need to “unify and conform” has existed for some time.  Several large companies agreed to begin to work together in a unified format somewhat recently.  The format is named after the group that created it.

MPEG (Motion Picture Experts Group): The coalition of video experts that develop new formats for video creation, compression, and storage.  The technological advances they are responsible for are named after them.  The most widely used formats worldwide are theirs, including H.264.

H.264 AVC (High Definition Advanced Video Coding #264, part 10): The most widely used format for recording and compressing video.  There are several different “parts” and “versions” that relate to different types of hardware and usage.  Essentially they work with varying amounts of efficiency, but all do the same thing.

RS-485 (Radio Standard #485): This is simply a format for broadcasting data over an analogue communication type.  It is usually connected via a pair of wires and is the most common method for connecting a PTZ camera or remote OSD connection to a DVR for control purposes.

CIF (Common Intermediate Format): The standard size of a single video image for video and teleconference purposes.  This size and format was later adopted by other industries (like security cameras).   It’s actual size is 352 x 240 in NTSC terms.

D1 (Digital Format): One of the earliest formats of Digital Imaging.  It was created by Sony and Bosch and was replaced with CIF as a more efficient standard.  4CIF is sometimes called D1, but they are slightly (almost undetectably) different in size.  D1 is 720 x 480, 4CIF is 704 x 480.

VGA (Video Graphics Array): A display adapter created by IBM designed to be the state of the art in graphics display.  It has a display resolution of 640 x 480 and due to advances in technology, has been mostly replaced by the HDMI format…

HDMI (High-Definition Multimedia Interface) and DVI (Digital Video Interface): These are the two current display adapters in use today for High Definition Video transfer from a device to a display unit like a monitor or television.  HDMI supports audio and video, where DVI is only for Video Information.

RAID (Redundant Array of Independent Disks): A system of arranging multiple hard drives in a system that simultaneously record.  This is found in CCTV systems when it is imperative that footage is stored.  Essentially, two drives are used redundantly so that if something happens to one of them, the footage is not lost.

FPS (Frames Per Second): This is the number of pictures taken or displayed in a second.  It is said the human eye sees between 24-28 frames (pictures) per second before the perception of pictures is no longer possible.

FTP (File Transfer Protocol): One of the original ways of transferring and storing files on the internet.  The idea of “Cloud Storage” is really just a FTP site, except its the next level since programs can be run there as well.

LED (Light Emitting Diode): This is a newer technology light bulb.  Its essentially extremely small and efficient.  They can be made in visible natural light frequencies and non-visible infrared light frequencies.  They’re often placed in clusters on the front of a camera to provide “invisible” illumination when there is no natural light present.

VAC (24) (Voltage Alternating Current): This is a format/type of power delivery for electrical devices.  It’s less common in CCTV solutions, but superior in some ways.  Because it uses Alternating Current instead of Direct Current, it allows longer distances to be traversed without as much loss.

VDC (12) (Voltage Direct Current): This is a format/type of low voltage power delivery for electrical devices.  It’s the most common format in CCTV solutions as its inexpensive to manufacture and provides electric in a format that does not require regulation, as DC devices only draw the amperage they require.  The downfall is the distance DC power can travel is lesser than that of AC.

TVL (Television Lines): This is a measurement of the “sharpness” the camera is capable of.  If you slice the image captured into tiny slivers, this would be the # of horizontal slivers required to create the image.  There will always be more lines vertically than horizontally, but those are not measured due to variances in chip manufactures. It is however always the case that the size of the line is exactly the same as the horizontal size, so the sharpness remains.

AGC (Automatic Gain Control): This is the ability for the camera to adjust on its own to varying intensities and types of light input.  Its a highly desired feature for quality cameras

OPLF (Optic Low Pass Filter): This feature can be digital or physical.  Essentially, its the ability for a camera to remove certain frequencies of light that can be degrading to a sensors ability to produce useful and accurate images.  These frequencies are often the artificial ones created by fluorescent lights, or similar types of light.

EXView: Simply the brand name of Sony’s most recent CCD sensor.  Also their flagship.

SuperHAD: Another brand name for a higher end Sony CCD sensor.

Dual-Voltage: The technical term for a device that can be connected to more than one voltage type.  In the case of CCTV systems, it often refers to a device that can be powered with 12VDC and 24VAC power.  Sometimes in the case of IP devices it also refers to POE.

Power Supply: This is a device that plugs into a wall outlet and converts the standard 110/120 VAC from the wall into a format usable by an electronic device.

Vari-Focal: This refers to an adjustable lens on a camera.  They can usually vari with zoom distance (mm range) and focal distance (the sweet spot of clarity).

White Balance: A setting in the camera that allows for adjustment of what “natural white” looks like.

Effio: The brand name for Sony’s newest and most powerful camera DSP.

Resolution: The size of an image created by a camera or recorder.

Quality: The clarity and sharpness of the image created by a camera or recorder (often confused with resolution).

Megapixel: The defining term for images over a million pixels in size (big).

Auto-tracking: The ability for a motorized PTZ camera to lock on and follow a moving object.

Channels: the ports in which cameras are plugged into a DVR

Ports: Digital hallways which data travels through a router, switch, or hub in order to reach another device or destination connected.

Hybrid: A recorder that is both a DVR and a NVR

650tvl Auto Zoom True Day/Night Color At Night BulletDay/Night: The ability for a camera to switch from color mode to black and white for lowlight.

C-Mount (cs-mount): The type of screw on lock used by CCTV box cameras for their lenses

Lux: A measurement for an amount of light.  Often more of an opinion, than a true gauge.

Sens-Up: The ability for a camera to enhance small amounts of light to continue to produce usable images digitally.

Pixel: A single dot in an image.  This does not designate the size of a dot… It can be any size.  Its simply just one of them.  The size of the dot is determined by the display device.

Illumination: Lighting.

Motion Detection: A software feature of a camera or recorder that allow it to determine if an object has moved within the field of view of the lens of a camera.

Mirror: the ability to create “flipped” images that appear to be upside down or reversed from the capture point.

Cloud: Offsite storage from the internet for files.

Best Medium To View Security Camera Footage

Monday, December 10th, 2012

best medium to view security footageIn recent years, technology has transformed how people review security camera footage. People can still review video surveillance tapes conventionally, by sitting down in front of a television. Mobile technology, however, has opened up the possibility of watching security tapes anywhere. In fact, with new technology, there is no need for tapes anymore. Everything can be stored digitally. Here is a look at the ways security footage can be stored and reviewed.

Conventional Mediums for Storing Security Footage

VHS Tapes

VHS tapes are the oldest medium that some people still use to store security footage. Many people actually prefer VHS tapes. They see these as the most economical way of storing video footage. The tapes themselves are extremely inexpensive and can be found at most technology stores. They can be watched via a television that is connected to a VCR or with a battery-powered VCR player. The easiest places to find a VCR player are garage sales, estate sales, flea markets and pawn shops. In these settings, VCRs rarely cost more than a few dollars.

VHS tapes have two disadvantages when they are compared to the other mediums used to store security footage. First, VHS tapes are bulky, and they do not have a lot of storage space. In some situations this is fine, because cameras can record over old tapes. Even a few VHS tapes take up space, though.

Most security systems that rely on VHS tapes keep the footage on-site. This is the second disadvantage of VHS tapes and VCRs. When used, this equipment is kept either in a safe or locked in a protective cage, whether it is a cabinet or actual cage. No matter how secure the protective barrier is, thieves and vandals can break it and steal or destroy the video evidence. Data systems that keep the video evidence off-site are much more secure, because their evidence cannot be destroyed during a burglary.


DVDs and DVD players can be used in pace of VHS tapes and VCR players. DVDs are even more readily available than VHS tapes, as is the equipment to play them. DVDs can be played on and DVD player, Blu-ray player, portable DVD player and nearly all computers. With the right software, it is easy to rip a security DVD into a file and email that file as an attachment. DVDs also are able to store more data than VHS tapes can.

DVD players, however, are not without disadvantages. First, the equipment needed to play DVDs costs more than a VCR player. Most businesses, however, can afford this additional cost or already have the necessary equipment. For most, the convenience of DVDs, when compared to VHS tapes, far outweighs the additional costs.

DVD-storage methods also suffer from the vulnerability of being on-site. In theory, the video feed could be sent to another location and then recorded on DVDs. Most systems that use this type of off-site storage, however, employ a different method of data storage.

Newer Mediums for Storing Security Footage

Hard Drives

Data can also be stored on hard drives. The upfront cost of a hard-drive storage system is much higher than that of a DVD system or, especially, a VHS system. After the initial investment, though, hard drive security footagebusiness owners do not need to purchase more tapes or DVDs.

Everything is stored on a hard drive or multiple hard drives. Once space is limited, old data is deleted. A new recording then uses that memory, until it becomes old.

Hard drives have several advantages over both VHS tapes and DVDs. First, video stored on a hard drive is already in a form that is easily shared, whether through email or on a thumb drive. VHS data and DVD video must first be transformed into a file. The lack of incurring costs is another major reason why people are willing to purchase a hard-drive video surveillance system. Third, this method is a green way of storing data, because it does not require VHS tapes or DVDs that will eventually be in a landfill.

People who rely on a hard drive need to understand that hard drives occasionally fail. This is rare, but it does happen. If a hard drive fails, then the business will need to purchase a new one. If a hard drive fails and has important video footage, it might be possible to recover the data. This can be expensive, though, and it cannot be guaranteed.

Hard drive security systems can either store the data on-site or off-site. If stored on-site in a local hard drive, then the system is susceptible to the same risks that the VHS and DVD systems are. A burglar could destroy the hard drive or steal it. If the hard drive is located off-site, then this is not a risk.

The Cloud

Cloud computing is an old concept, but it has been recently developed to a very practical level. When people store data in a company’s cloud, it is stored on that company’s servers. This is an easy way to store security footage off-site, so it cannot be destroyed or stolen during a robbery. It also is the easiest way to share the video footage and requires no space. In many cases, the data can be streamed directly onto any wireless device.

Cloud computing has many advantages, but business owners should understand how it works before they use it for security footage. Data stored in any cloud is just on another company’s computer. In most cases, these computers, or servers, are run by major corporations, such as Google, Apple and IBM. The computers are generally extremely stable, and there is usually a back-up system in place. If the company providing data storage folds, though, then their computers will be turned off and the security footage deleted. Therefore, it is important to use a reliable company for cloud computing,

Cloud storage comes with two other disadvantages. Many companies offer a little free storage, but this is not enough storage to save security footage videos. Companies will have to pay a small monthly fee to use the cloud storage. Also, there is a slight risk of someone hacking into the data. This risk is minimal, however, as long as the hosting company is well-known.

Transferring Mediums of Storage

Many older businesses have a VHS-based or DVD-based security system already in place. They would like to update their technology, but cannot justify the cost of installing all new equipment. For these companies, transferring data from VHS tapes or DVDs to a digital form can be a practical solution. The process is tedious, but it can provide significant savings.

Converting VHS Tapes to Digital Files

Converting VHS tapes to digital files requires a special piece of hardware, which reads DVDs and connects to a computer. Many electronic stores carry such a device, and VHS conversion hardware can be found online at competitive prices. Any hardware purchased should also come with software for creating the files.

When using this hardware, each VHS tape must be played from beginning to end. The process takes a long time, which is why many businesses outsource this to a local company. It would be impractical to convert all of a company’s VHS security tapes to digital files. If only one or two are needed for evidence in a court case, however, then this can be a practical solution.

Converting DVDs to Digital Files

Converting DVDs to digital files, which is known as ripping them, is much easier than the process of converting VHS tapes to digital files. Most computers have the technology needed to read and rip DVDs. Most computers also have a software program that will do this, but not all do. Those who do not have the necessary software can find a suitable program for free online.

Protecting Different Mediums of Security Footage

Protecting security data from on-site thieves is only one aspect of properly taking care of the video footage. Physical data must be protected against light and water, which can damage it. Digital data must be protected against hackers. This is done with encryption.

Encryption makes it difficult to illegally access digital data. It scrambles the data in a manner that only the encrypting program knows. It is then very difficult, although not impossible, for another program to crack the encryption. Meanwhile, the encrypting program can play the video without a problem. There are various levels of encryption, and all computers have encryption software already on them.

Technology has revolutionized how people store security data. With every advancement, video can be stored a little more securely. The biggest recent advancement in this field has been off-site data storage for security systems. Future mediums for video storage promise to be even better than the ones we have today. For now, though, there are good, digital ways to store security footage. Contact us today for more information.
