Basic Port Forwarding for the DVR & NVR

Written By:
Wednesday, June 12th, 2013

security system support groupsToday we will be exploring a simple world of port forwarding. For those of you who like to be hands on and grasp the “What, Why, and How to do” or you simply want to complete this segment of your job or project and Tech Support is unavailable I welcome you to proceed reading. I will begin with, “Make sure you have a PC, DVR/NVR, router and/or modem all [plugged in and ready to go. Also please obtain all passwords to each device (if necessary) to ensure flawless setup as we go from procedure to procedure. Once you have done so please access your START MENU on your PC.

{Depending on what operating system you have, the above picture may vary.)

Choose the RUN option and then type in the command CMD. Then hit the enter key and you should have a window like the following:

setting up your security system

In this window, type in the command IPCONFIG and hit the enter key, this will pull up your LAN (Local Area Network) IP scheme. The one you will see my network in is a 192.168.1.xxx scheme. If yours is different, PLEASE DO NOT DESPAIR**, following along with the same process while subsitutuing my scheme with yours, will provide you with the SAME results. You should have now the following window:

As you see in the picture above my gateway 192.168.1.1 (which is my network scheme). The IP address of the PC I am using is 192.168.1.104. This is the unique IP belonging only to my device (my computer). This is the name, if you will, that the LAN knows my PC as. Every device that is attached to my network is issued its own unique IP address. Now our DVR/NVR and IP Mega Pixel cameras all have a default IP address of 192.168.1.108. On my network 192.168.1.108 is already taken so I will establish the IP of the DVR to 192.168.1.120. I suggest anyhow, to always change the IP address of any our devices to a known open IP on your network. You can see if an IP is open or not by pinging your network. You can check this in Command Prompt by typing in PING (hit the space bar once) and then the desired IP based on your established scheme. It will look like so:

(Above you can see this IP address is assigned to another device due to the com packet replies)

(Above you can see the IP address is not in use)

Now that we have established an open IP to assign to the device lets change it. If you right click on the mouse of the DVR, chose the following:

Main Menu -> Settings -> Network. Configure your network to the chosen IP in the IP address field. Make sure to change the Default Gateway in the respected field as well if your network requires. While we are still in this menu, let’s go ahead and assign our desired ports for the HTTP and TCP. I for instance will change the HTTP to 88 and keep the TCP port as it defaults of 37777. I now will save my configuration. (If the DVR prompts you that it wants to reboot, this is fine and a necessary function. Just hit okay.) Now let’s move onto creating PORT FOWARDING rules on our network. Normally you can just open up any browser and type in the DEFAULT GATEWAY of your IP scheme. Please refer to the picture below:

how to set up port forwarding for NVRs

(Before)

(After)

I will now access my router by putting in the password. Once Inside I can now create port forwarding rules for my device. Based on your router and/or modem the following pictures will not look the same. The current router I am using is a Linksys 1750AC.

(Main Menu once you log into the Linksys 1750AC)
single port forwarding for security cameras

I will now go to the Security tab at the bottom left hand corner, then choose the APPS & GAMING tab, and then SINGLE PORT FORWARDING.

As you can see in the above I have created (3) different port forwarding rules for the IP address 192.168.1.120 which is my DVR. You WILL have to only create two, the HTTP PORT & TCP PORT. Once completed be sure to save the configuration and now let’s check to see if our external is now connected to our internal with this two ports. We are going to proceed use a website known as: CanYouSeeMe.org

I hope you got the same results as I did! If all was successful you ports should have shown a SUCCESS: I can see your service on (your external IP here) on port (your desired port you choose). If not, again do not despair***, please try following the same process over or contact us for your free technical support on OUR products. Please see the below for the DVR view on a browser:

How To Find The Best Wireless Security Camera For Your Home

Written By:
Thursday, August 16th, 2012

Wireless security cameras are designed for both indoor and outdoor use. A wireless camera requires no wires between the camera and the receiver. They are easy to install and can be moved from one location to another. Wireless cameras are available in many sizes and forms. The cameras capture black and white, color and infrared images. The security system connects to any computer, television or digital video recorder for easy viewing. To find the best wireless security camera for your home, decide how many cameras you need.

If you want to monitor the entire perimeter of your home, then you will need several cameras. Consider the image quality when choosing a camera. An HDTV camera has a higher resolution and will cover a larger area than a CCTV or an IP camera. The benefit of an IP camera is the fact that you can connect multiple cameras to your digital video recorder. IP cameras can connect to the Internet providing remote viewing from any computer. An Ethernet switch provides the power and the Internet connection. HDTV cameras are useful when you need to capture clear and precise images such as license plates or faces. Today’s technology allows home security systems to be enabled or disabled by using a computer or smartphone.

To monitor the inside of your home, you can install burglar alarms on your windows and doors. Carbon monoxide, fire and flood alarms can easily be added to your home security system. Carbon monoxide is known as the silent killer because it has no smell or taste. Heat detectors are useful in areas of the home such as laundry rooms, garages and other places. Fire alarms can be monitored by a security company to contact you or the fire department. Flood alarms are used to detect the presence of water or moisture in the event you have pipes that burst or leak. They also monitor moisture levels to warn you of the presence of mold and mildew. Inspect these sensors on a regular basis to prevent the buildup of dirt and debris.

Home burglar alarms are helpful because they alert you to the presence of an intruder whether you are home or not. If you choose to have your burglar system monitored by a professional security company, they can install glass break sensors on your windows. They use single or double break technology to detect glass breakage. Single break technology will trigger the alarm from the sound of glass breaking. Double break technology must hear a thumping sound followed by the sound frequency of glass breaking before the alarm is triggered. Monitored home burglar systems may have to be adjusted to prevent false alarms. Many cities have penalties for frequent false alarms. False alarms cause local law enforcement to use resources that are needed elsewhere in the city.

Emergency health response systems are a good choice for people who have health problems, the elderly or just for the peace of mind. These emergency response systems can alert local authorities to the presence of a medical emergency inside your home. Panic buttons are located on the home security system’s keypad and also by small remotes. You can choose to have the system contact you or the local emergency personnel. There are hidden indoor security cameras that can monitor your babysitter or any situation. These cameras are small and discreet and provide helpful information. They connect to a small digital video recorder and can be wired or wireless. Consult a professional home security company to determine which security system will work best in your home.

Combining a home security system with home safety tips will improve the security of you and your family. Don’t hide a key under the door mat or anywhere else near the home. This will be the first place a burglar will look. You can buy locks for your doors that require opening with your fingerprints. This is a good idea if you are constantly losing your house keys. If one of your locks on your door breaks, be sure to replace it right away. Two cylinder locks are available but they require a key to open the door from the inside and out. This can cause a hazard if there is an emergency in the home and you need to leave quickly. Install deadbolt locks on sturdy doors that lead into your home. The deadbolt should be attached to the door’s wood frame. Have a professional install your deadbolt locks if you’re not sure how to install them. Access doors into your home should be made of steel, wood or fiberglass. This will help prevent a quick entry into your home by simply kicking it. Install modern kick plates on doors leading inside your home. Hollow doors without good locks are easily kicked in by burglars.

Outdoor lighting can improve the look of your home. It also helps to deter crime. Most burglars don’t want to be seen and they like the cover of darkness. Install solar lights and motion detection sensors to lower your energy bills. If you have a privacy fence, you can add a beware of dog sign even if you don’t have a dog. Place home security signs and decals on your windows and doors to alert a possible intruder that you have security. You can also purchase fake security cameras that look like a real working home security camera. Driveway and garage sensors can be installed to detect movement. Keep the garage secured and locked at all times. Don’t leave the garage door open even when you are at home. This gives people who pass by the opportunity to stake out your garage. Lock the inside latch of your garage door with a padlock. Check your garage door remote to be sure it has rolling code technology. This technology changes your garage door code each time you enter the garage. If you must replace your garage door, choose one without windows to prevent a burglar from seeing if there is a car parked in the garage.

When you have a home security system installed, be sure to keep it activated even when you are at home. Many people either don’t turn it on when they are home, or they forget to activate it when they leave. The key to protecting your family and home is to use the alarm system. It only takes an intruder a few minutes to enter your home and steal your possessions. Most burglars are looking for items that can be sold at the local pawn shop. Be sure to have your driver’s license number engraved on your expensive electronics. The burglar won’t be able to sell your items very easy. Keep curtains and drapes closed so they don’t reveal your home’s contents. Install sensors on all of the windows of your home. If an intruder tries to enter through the windows, an audible alarm will sound. This could be enough to send the burglar to another home.

Store your valuable jewelry, cash and weapons in a locked safe or a safe deposit box. If you purchase a safe for your home, you don’t want a burglar to be able to carry it out. Have it bolted to the floor, or be sure it is too heavy to be carried easily. The outdoor storage shed should be kept locked at all times. Installing electronic gates will help to keep a burglar out of your backyard. If you have a privacy fence, a burglar can get into the backyard and remain invisible to the neighbors. Get to know all of your neighbors in your neighborhood. Join your local crime watch program or start a new one. Most law enforcement agencies have crime prevention programs that you can join. Learn about the crime risk in your area. When you go on vacation, notify a neighbor to watch your property. Install timers for the inside lights of your home. This will make your home look like someone is home even when they’re not. If everyone in the neighborhood becomes familiar with who should or shouldn’t be there, then the community is safer. Most burglars will park down the street before walking up to your home. Neighborhood watch programs teach people to report suspicious vehicles.

Apartment and condo residents have the same security needs as anyone living in a single-family home. When you move into an apartment or condo, have the maintenance staff change the locks. You don’t know whether the old tenants still have a key or not. Getting to know your neighbors is important. Report any suspicious people or activities to the neighborhood’s security team or local law enforcement. Reinforce sliding glass doors with a wooden bar, and never leave your doors unlocked. Purchase renters insurance to cover your possessions in case they are stolen. Don’t go to the laundromat at night, and be sure the apartment’s parking areas are well-lit. Ask the staff if you are allowed to install a security system in your apartment. Call a professional burglar alarm service to install the security system.

When you purchase new electronics don’t put the boxes out with the regular trash. This will alert a possible thief to the fact that you have this item. Break the boxes down and place them in plastic garbage bags. Online social media sites are a great way to show family and friends your vacation photos. They can also be a tool for an intruder to know that you’re out of town or when you will be leaving. It’s hard to imagine but the risk is still there. Take care about who you tell about your vacation plans. Leave a spare key with a trusted neighbor or family member. Have them check on your property while you are away. They can pick up your mail, newspapers and any flyers attached to your door. It would be ideal for them to open the drapes in the morning and close them at night. You can also ask your neighbor to park their vehicle in your driveway. You want to convey the message that someone is at home.

If you are selling your home without the use of a real estate agent, there are a few security precautions you should keep in mind. Show your home by appointment only. Don’t set an appointment to show your home when you are alone. When you decide to have an open house, clear the rooms of valuables and electronics. It’s best to sell a home with a minimum amount of personal possessions. If you use a real estate agent and they want to place a virtual tour of your home on their website, then be sure there are no expensive items or electronics in view. Some criminals check these out to choose a property to burglarize later when no one is home. If you are buying a new home, have the locks changed as soon as possible.

A safe room is a room that is reinforced with a lot of concrete and steel. They are used for emergencies such as bad weather or a home intrusion. Adding a safe room to your home will improve your home’s security plan. Keep bottled water, snacks and a cellphone in your safe room. A phone that is connected to a land line is also helpful to phone the authorities from inside the safe room. A land line phone will give your home address to local law enforcement agencies just by dialing 911. If an intruder enters your home, you can run to the safe room. Teach family members about home security safety tips and the use of the safe room. Search the Internet to learn more about installing a safe room in your home. There are many ways you can improve the security of your home. When you combine many security techniques they become a powerful deterrent for an intruder. If you make your home difficult to enter, and you have outdoor surveillance equipment, an intruder may decide to go to another home.

Network Security Camera

Written By:
Thursday, August 2nd, 2012

Although property crime statistics in the United States are steadily declining, according to Federal Bureau of Investigation, there is still a great need to safeguard your property. Whether you’re interested in adding security to your home or business, network security cameras continually monitor your property. While homeowners may feel security cameras are specifically made for businesses, by visually monitoring your home you not only ward off potential crimes by the sheer presence of the camera, but in the unfortunate event of theft or burglary the videos may help law enforcement identify and capture the thieves. Although there are a wide array of security cameras on the market, few offer the security and flexibility as network security cameras. If you’re in the market for security cameras, you should consider installing these items not only for their reliability, but also for the peace of mind their presence provides.

What is a Network Security Camera?

  • Network security cameras, also referred to as IP cameras, have the foundational purpose of traditional CCTV, or analogue, cameras; however, their method of sending and receiving data is much different. In a foundational sense, network cameras are quite similar to webcam as network cameras utilize the Internet to transmit and store recorded images. However, the similarities between webcams and network cameras end there. Network cameras are separated by two primary categories: centralized and decentralized cameras. The following are the two primary differences between these two camera setups:
  • Centralized Network Camera – A centralized network camera is one that requires a central NVR, or Network Video Recorder, to manage incoming recordings, video storage and alarm sounding if the cameras are attached to an audio alarm system. Commonly mistaken for a DVR, an NVR is a software program designed to record and store video from a network camera in a digital format. These digital videos are then saved to some form of digital mass storage such as a USB flash drive or an SD memory card. Although an NVR is solely software, the actual software is typically stored on a dedicated device that connects to various network cameras. The primary difference between an NVR and a DVR is an NVR receives its incoming video signals from an Internet network while a DVR receives its video signals from a direct connection to the camera. Another distinct difference between these software programs is how videos are processed and encoded. DVRs process and encode videos after they are streamed to the unit while NVRs process and encode video signals before being sent to the recording device.
  • Decentralized Network Cameras – A decentralized network camera is one that does not use an NVR. Rather, these cameras feature built-in video storage capabilities such as hard disk drives or flash drives. This form of storage is more streamlined, but features limitations such as not being able to store large quantities of data.
  • Types of Network CamerasNetwork security cameras are available in a wide array of formats and designs. However, while there are many designs there are seven primary camera types. Manufacturers may alter the features within these camera types; however, every network security camera is based in one of the following.
  • Outdoor Cameras – Designed specifically to be used outdoors, these network cameras feature weatherproof casings, significant temperature operation range, day and night recording as well as a tampering alarm. Typically used to monitor parking lots, campuses and traffic conditions, an outdoor network camera is ideal for areas that require 24/7 monitoring in all weather conditions.
  • Thermal Network Cameras – During moments of complete darkness, thermal network cameras are able to clearly capture images based on heat radiating from objects. All objects radiate a certain amount of heat, and this camera type is designed to capture the details from a heat source. The primary benefit of this camera design is its able to monitor property in complete darkness. Therefore, there’s no infrared LED lights illuminating the area. In complete darkness, onlookers are unaware they are being monitored. The downside of this camera design is its lack of detailing. While figures are clearly seen, small details typically captured by infrared security cameras are lost.
  • Megapixel Network Cameras – These cameras are designed to capture highly detailed images. Designed with the latest in high resolution surveillance technologies, megapixel network cameras, also referred to as HDTV cameras, can clearly record facial features or items a customer purchases.
  • Covert Cameras – As its name suggests, covert cameras are designed to seamlessly blend into its environment. Thus, onlookers are unaware of its presence while it continually captures their facial details and their actions. These cameras are ideal for monitoring customers in areas of a store that are unseen by wall or ceiling security cameras.
  • PTZ Dome Network Cameras – PTZ dome network cameras are designed to discreetly monitor a wide angle area. These cameras are housed in a dome, thus onlookers are unaware if the camera is pointing at them or not. The camera operator may manually tilt, zoom and pan while capturing high-quality video. Features typically found in these cameras include EIS, or electronic image stabilization, auto tracking and auto camera flip.
  • Fixed Dome Network Cameras – Like its name suggests, a fixed dome network camera does not offer lens movement. Rather, it is a fixed camera housed in a dome. The primary benefit of this camera design is its discreet design; however, the main drawback is its inability to interchange its lens. However, many fixed dome cameras offer a varifocal lens, which allows the field of view to be manually changed by an operator.
  • Fixed Network Camera – This camera design is perhaps the most common. Implemented to be visible to onlookers, a fixed camera cannot pan or rotate as its field of view is static. However, many fixed network cameras allow operators to change its lens. For example, a single fixed camera may be adjusted to house a wide-angle, telephoto or normal lens. Some camera designs are outfitted with a varifocal lens to adjust its field of view.

 

As stated earlier, these are simply the most common foundational designs. Each of the aforementioned is available in a wide array of configurations. To determine the best network security camera for your property, research available options and features. Remember, every property features unique monitoring challenges and the goal of a security camera system is to overcome these challenges for adequate monitoring.

Analog Resolution vs. Network Camera Resolution

Many property owners who are interested in security camera systems desire to have cameras with high video resolutions. The reason behind this is the higher the resolution the better the image quality. Cameras with low screen resolutions may capture the happenings of an area, yet if the images are blurry or fuzzy, these cameras do little to actually assist law enforcement in the apprehension of a criminal. Within the realm of security cameras, a major question is, “What is the resolution difference between traditional analog cameras and network cameras?” The recordable resolution of security cameras is dependent on the restrictions of the actual recording device such as a DVR for analog cameras or NVR for network cameras. With analog cameras, the DVR is restricted to a maximum resolution of 720 x 480 pixels. However, network cameras offer a wide array of resolutions. For example, many NVR programs support 5 megapixel, or higher, screen resolutions. This results in a video resolution of 2,592 x 1,944 pixels. Therefore, if image quality is paramount in your decision making process, network security cameras are your only option. Review various NVR programs, as some software programs may feature resolution limitations.

Benefits and Drawbacks of Network Security Cameras

As with any other form of security cameras, network security cameras feature benefits and drawbacks. Before making a purchasing decision, it is imperative you review the benefits and drawbacks to determine if the financial commitment of network cameras is worth the benefits you’ll receive.

Benefits

  • Installation Flexibility – Perhaps the most notable benefit of network cameras is its installation flexibility. Unlike analog security cameras, network cameras are able to be installed anywhere on a property where there is an IP network. This is not limited to Ethernet cable only networks. Many network cameras are able to operate and transmit signals through a wireless Internet signal.
  • Encryption – Securing the images of a camera is just as important as having a security system in your business or home. Network security cameras offer two layers of data safeguarding. Firstly, video images are encrypted before ever being transmitted to the NVR. Secondly, videos are automatically encrypted and authenticated through encryption languages such as WEP, AES, WPA and TKIP.
  • Video Resolution – As discussed earlier, network cameras offer significantly higher video resolution when compared to analog cameras. This increase in resolution provides clearer videos capable of identifying facial features and car license plates.
  • PoE Connectivity – Network security cameras do not need to be plugged directly into a power source. Rather, these cameras may operate by connecting the camera to a PoE, or Power over Ethernet, protocol. This system powers the cameras trough the Ethernet cable instead of through a traditional power source.

Disadvantages

  • Cost – If cost is an issue, then network security cameras may not be the ideal surveillance solution for you. Typically, network cameras require a higher upfront cost than analog security cameras. However, this disadvantage may quickly disappear as the use of network cameras increases. The increase in demand will likely lower the cost of these camera systems.
  • Video Interception – Although not very common, video signals may be intercepted if network cameras are connected through an unsecured wireless network. This raises the security threat as criminals could potentially access video streams and monitor the security environment of a business or home. This undermines the effectiveness of the cameras and actually facilitates a crime. Avoid this scenario by never connecting network cameras through a public, or unsecured, wireless signal.

While it may seem that the benefits of network security cameras far outweigh its drawbacks, it is important potential buyers seriously weight both the pros and cons before making a decision.

Ptz Security Camera

Written By:
Friday, February 10th, 2012

ptz security cameraSecurity cameras for many homeowners and businesses are merely a part of ownership today. In fact, they are so common many simply take them for granted. However, as common as they might be, any camera system must be chosen wisely. The reality is, that some people may assume that a camera prominently displayed, will solve their security problems. Subsequently, cameras are installed and forgotten about. Practically speaking, any camera, regardless of quality and capabilities, will provide some level of security. When cameras are present, they tend to restrain people, and can prevent certain crimes.

There Is More to a Camera than Meets the Eye

A Ptz security camera or one that pans, tilts and zooms is a high quality camera that literally provides 360 degrees of coverage during the day or night. Camera systems are advanced to the point where they can be controlled remotely, as well. The systems are self-contained and are capable of working independently or on a network. They have digital zoom, and can track movement 360 degrees side to side which is called pan, and up to 270 degrees up and down, which is tilt. Many models are also capable of recording in full color.

High quality cameras will be self-contained, which means they have an internal memory, can record in low light and will operate in any type of weather. For extreme temperatures, the camera has on board heaters and fans. These cameras are ideal for monitoring people or vehicles in outdoor settings year around. Locations would include tollbooths, entrances to factories and even sports stadiums. They can be remotely viewed using several different platforms, as well. Many times, it is necessary to scan faces of people at large events. The cameras can transmit in real time, using Wi-Fi to a single computer or a network of computers. The images can be recorded using the computer’s hard drive or a dedicated digital video recorder or DVR.

Why Do You Need Pan Tilt and Zoom

It is quite easy for anyone to avoid a camera in a fixed position. People can easily move out of the viewing angle. Fixed cameras are however, ideal for hallways, elevators and small rooms where individuals cannot move out of range. Having a Ptz security camera ensures that regardless of the location, all angles are covered. Intruders cannot sneak up on one, so to speak. Once the camera notes movement, the camera’s view cannot be avoided by moving in one direction or the other. Additionally, individuals cannot crouch below view either. Having zoom capability brings a person’s face, or any object they may be holding, into view.

Cameras that pan tilt and zoom provide more security at entrance points. Homeowners want to know who is at the front door before opening it. Having the right camera installed ensures they have a clear view of anyone standing there. People cannot move in under the view or sidestep the lens. By using the remote zoom capabilities owners can focus on the visitor’s face, and hands. Focusing on the hands determines if they are carrying anything that would cause concern.

Cameras with Ptz capabilities are essential in banks, retail and convenience stores. Their job is twofold, to monitor customers and employees. It is important to be able to track cash transactions. In many cases, a dedicated camera with a digital zoom is used for each register. The camera’s only job, in some cases, is to monitor the cash drawer. Large businesses many times have cash counting rooms where zoom capabilities are critical, as well. The rooms will also have cameras that continually pan and tilt.

Ptz Security Cameras Are used Worldwide for A variety Of Reasons

Law enforcement routinely employs these types of cameras at airports, and other public arenas. They in most cases will focus on facial images and compare those images to a database. The use of facial recognition software is quite common in law enforcement today. This practice is much more prevalent in Europe, which claims to use the cameras and software to track terrorists.

To put it in perspective according to the market research firm, IMS over 30 million surveillance cameras have been sold in the United States in the past ten years. According to Popular Mechanics online, this amounts to approximately four billion hours of video footage each week. Cameras of all shapes and sizes exist in public and private. Predominantly they are used to catch people in a criminal act, track employees at work, check on babysitters and provide personal protection to homeowners.

Where to Begin When determining A Camera’s Location

You may own a small business with a front and back entrance. Should the camera be placed inside covering the door or outside scanning the sidewalk? To capture the image of anyone breaking in the front door, a camera must be located over the entrance outside. The dome style with motion-activated pan, tilt and zoom with night vision is ideal. The camera will also provide coverage if the business wishes to display products and goods on the sidewalk during the day. The back entrance should of course have the same dome camera mounted outside over the back entrance. A Ptz security camera should be located to cover the cash register, with its angle adjusted to view any employee or customer standing at it. Additional tilt, pan and zoom cameras should be positioned to cover the sales floor. You must decide whether additional cameras are needed for the stockroom or storage areas.

As the owner, you may not be there during business hours every day. You can remotely view and operate a wireless system. Using the camera’s Wi-Fi capability, you can view it through your home computer. The cameras can be set to transmit to a computer, which you can access from any other computer or smart phone. This allows you to view in real time what is happening at the business. You can by remote control, zoom, tilt and pan any camera from your computer.

Larger businesses, such as warehouses and retailers have enhanced their security through the proper use of cameras, as well. Strategically placed pan, tilt and zoom cameras have reduced thefts by employees and customers alike. Essentially, no business is immune to theft by their employees. Having the right surveillance equipment in the right places can reduce costs.

Inventory shrinkage through thefts and mishandling of the product will be reduced. In some cases, recorded images can be used to defend against liability or workers compensation claims. Shoplifting is a common occurrence and without video evidence, a shoplifter could walk free. This of course, would increase the overall cost of doing business. The pan, tilt and zoom capabilities play an important role in verifying the identity of individuals.

Homeowners place a high priority on security. With busy work schedules, it can be nerve wracking trying to stay connected with everyone. However, having security cameras installed can ease the burden somewhat. You as a parent can check in anytime of the day or night to view real time images of your home and family. Location and types of cameras are a crucial part of home security.

After the decision has been made to install a Ptz security camera, the next step is location. The front entrance is an obvious choice. A camera that can pan, tilt and zoom and record in low light is important for this critical area. Owners can inspect any visitors before opening the door. They can zoom in on their face, hands and look for any other individuals lurking nearby. With 360 pan capabilities, no one is out of the camera’s view.

If you have a large estate, you can place one at the gate entrance. Leave the gate shut until you have visually inspected the vehicle and occupants using the security camera. Cameras with a zoom feature can also be used to capture a vehicles license plate. Having the plate number is generally only beneficial to law enforcement. However, many gated communities use plate numbers to identify occupants of the community. Having a camera that can capture a plate number may prove to be beneficial at some point.

Larger areas can be monitored more easily with less equipment. Cameras that have a full range of motions will reduce the number of cameras needed. However, the overall range of the camera must be taken into account. Larger areas can be covered by staggering cameras at overlapping intervals.

Place a camera so that the back and side yards are being monitored. Criminals of course many times will attempt break-ins from the back of the house. It is important that their image be clearly recorded for investigative purposes. Obviously, it is every homeowners hope that the camera will scare them off, but at times, this is not the case. That is why having the right camera in the right place is important.

Inside the home can be as important as the outside. Having a baby sitter or nanny inside your home to watch your children is a very common practice. You as a parent must use whatever means necessary to ensure your children are protected however. This means cameras must be placed so you can view how they are being cared for in real time, at any time.

Cameras are simply becoming a part of everyone’s life. They provide security to families and property, and reduce operating costs for many businesses. Choose carefully when purchasing a Ptz security camera. Buying the right one today will prevent you from having to upgrade in a few months. Consult experts on the finer points of security, and do your research.

Surveillance Camera CCTV

Written By:
Tuesday, September 27th, 2011

Today’s surveillance camera CCTV systems have made “leaps and bounds” in technological improvements compared to the systems from just 10 to 15 years ago.  Not only that, but the camera’s prices have steadily decreased with the increase in technology.  All of this has lead to video surveillance cameras becoming a “household word” for family protection and safety as well as business protection and workplace documentation.

Original surveillance camera CCTVs were based on analog signals.  These systems and components of the systems were often referred to as CCTV or Closed Circuit TeleVision.  CCTV was so named because although it closely resembled a typical television studio system, there was one major important difference.

Studio television cameras’ video signals were boosted by the broadcast station and sent via radio frequency via a large antenna.  Once the signal left the broadcast antenna, anyone with a receiver could pick up the signal.  Video surveillance cameras however, sent their signal along a cable, directly to a specific monitor and recording device.  In this respect, the system was a “Closed Circuit TeleVision” system.  In fact, any system used for monitoring, surveillance, or security in this manner was referred to as a CCTV system.

Today, video surveillance cameras still operate on a CCTV based system, but to be accurate, we must redefine CCTV to make it somewhat looser in application.  Although modern digital video surveillance cameras also transmit their video signals via a cable to a Digital Video Recorder or DVR and one or more monitors, they also employ additional methods for transmitting their signals that must be taken into consideration of the definition of CCTV as well.

These cameras may also transmit their video data wirelessly via an on-board camera transmitter and antenna.  These cameras use modern day wireless technology often used in land-line based telephones such as 2.4 or 5.8 GHz technology or 900Mhz technology for broadcasting their signal.  These systems are designed to transmit their signal to a nearby receiver, which is usually plugged in by cable, to a DVR and/or monitor.

Another method that is employed today is the use of the Internet as a vehicle for networking and transmitting.  Video surveillance camera CCTV and their DVRs have the capability for connecting to the Internet.  When they do possess this feature they are often referred to as Internet Protocol or IP ready, because they deliver their transmission using IP format technology.

Although it is true that individuals other than who the video images are intended for can gain access surreptitiously, the intent of these wireless broadcasts and Internet transmissions are directed to a limited number of very specific viewers.  Thus, although our definition for CCTV as now become a bit broader in scope, it is easy to see why even today, these units are often called surveillance camera CCTV systems.

While we are on the subject of CCTV versus new video surveillance cameras, it would be prudent to mention that there is some carry over from the “analog days” of CCTV to the current “digital era” which can make the comparison of components or the selection of a system somewhat confusing.  This primarily involves the use of reference to the detail or resolution of the video image created by the camera and displayed by the monitor.

Electronic video images may show a varying degree of detail.  That is evidenced by the contrast between standard television broadcasts and those called High Definition (HD).  Television was originally displayed on a Cathode Ray Tube or CRT (also called the “picture tube”).  The CRT reproduced the image on its screen by shooting an electron beam horizontally at the rate of about 60 times per second.  To a large degree, the number of horizontal lines determined how detailed the video appeared.  In this situation, the more lines, the smaller the lines, the greater the detail of the picture.

Today, however, most televisions are like computer monitors; they are Liquid Crystal Displays (LCD), plasma, or Light Emitting Diode (LED) displays.  These monitors display tiny dots called pixels instead of horizontal lines; therefore, they can display a much higher detail picture.  Yet, many video surveillance cameras still specify their picture quality in terms of the older, horizontal line method.  It’s important to know that the lower end of resolution or detail is from about 300 up to 650 TVL (TeleVision Lines).  Video surveillance cameras CCTV with 650 TVL displays can produce very high definition video images.
