What is the difference HDCVI, DVR, and IP NVR
Security camera systems come in many different forms and its best to know the difference between them all to help decide what system works best. Here at Security Camera King we sell three different types of technologies. They all have their advantages and disadvantages and just like everything else the more advantages you get with a system can come at a price. Starting at our lower end models is our Analogue cameras which have been the pioneer of security cameras and have served us well. Going to the top is our IP camera systems which produce high definition quality picture and is becoming a standard in the security camera world. Then right in the middle is our HD-CVI camera system which utilizes Analogs existing cable technology but delivers the same picture quality as our IP systems. Given the different options of security camera systems to choose from can give a little confusion but once broken down and dissected will turn confusion into knowledge and help make the right choice for a security system.

When security cameras became popular the first technology was called Analog. These systems worked by using coaxial cable to transmit signals from the camera to a recording device such as a VCR or more relevant a DVR. This technology has worked well for years and is still around today. The benefits of Analog are that its cheaper than most other systems, it is very reliable, and has many options of cameras and DVR’s. Analog is considerably cheaper then and IP or HD-SDI system and still gets the job done. To put in perspective, the difference in cost, if placed side by side a comparable 8ch Analog system and a 8ch HD-SDI system you will spend over 50% less on a Analog system. You won’t get the same picture quality but if you’re looking for a dependable video security system that will provide you a quality picture then this is the best option. The reliability of Analog systems is considerably higher than other systems because of the technology it uses and how it has been perfected for years. They increase in dependability if they are installed correctly and if quality cable was used during the install. The last benefit of Analog camera systems is that they have a wide verity of cameras and DVR combinations to help fit your budget. Cameras can have different technologies that can help with license plate capture or allow you to see at night with a technology called Infrared light and DVR’s can allow you to record at better resolution and faster frame rates. Analog is not the top choice but can give reliability and more options than most other systems out there.

IP stands for “Internet Protocol” which is the next camera system on the list and for most would be the best system for the money. IP camera systems work by using a standard Ethernet cable to connect several cameras together to your LAN “Local Area Network” in your house. What’s nice about IP cameras is that you don’t have to use a recording device on the other end to operate them, they all consist of their own web based program that can be accessed through your computer or a phone for viewing or local camera recording. IP cameras have the most sophisticated technology that gives them ability to achieve these types of operations. If the need to record your footage we sell NVR’s “Network Video Recorders” that allow you to connect up to 128 cameras to a single recorder. It also make it a central viewing station for all of the cameras you set up instead of logging into each individual camera. The cameras themselves can have different types of lenses which gives it the ability to view far away objects without distortion or view a wide shot for more coverage. The best thing about IP camera system is that you can record at a high resolution. In some cases you can record as high as 10 Megapixels! That’s 5x the size as your standard 1080p HD TV. With that picture you can digitally zoom into a video with little to no distortion. There are also other benefits to IP camera systems like POE “Power Over Ethernet” which allows you to use one cable (Ethernet cable) to send power and data to avoid the use of and additional power cable. Doing so can save you time and money for installations and repairs. IP camera systems are becoming more affordable every day and will eventually become the standard in security cameras.

Getting the best shot is what most people are looking for in a security camera system and this can be achieve using the same technology as out predecessor the Analog camera system. HD-CVI can give you the reliability and price of a Analog system but the picture quality of an IP camera system. There are also a lot more benefits to using a HD-CVI camera system for example you can transfer video, audio, and data all through the same coaxial cable. This is something that is possible through IP but new to Analog. This is a benefit because it will save you on wiring and time with configurations on each unit. It also makes it possible to control the OSD functions of the camera at the DVR source. This makes it easier to manage your fixed cameras as well as PTZ’s (Pan Tilt Zoom) The biggest advantage is you can record at 720p resolution ,normally found on a IP camera system, for over half the cost. It is a growing technology but shows its true potential in the field.

Knowing the products and technologies in the security camera industry can give you the upper hand in selling or for personal use. Analog gives you reliability and options all at a reasonable price. IP producing quality picture and on the move to becoming an industry standard. Last but not least HD-CVI which gives you most of the benefits of IP with a similar cost to Analog. Now that its broken down you can digest the information to make the best choice.

The Differences Between Megapixel IP Security Cameras and HD-SDI

Megapixel VS HD-SDI

What is the difference between Megapixel and HD-SDI Security Camera Systems? We get many calls on a daily basis with customers asking whether or not they should choose one over the other. There are good and bad things about both. You should be aware that even though both systems can record at megapixel resolution, there are vast differences about both systems that you may want to consider before making your choice.

You will find many different debates between both surveillance systems. The easiest way to choose which system is best for your application is to take a look at these differences below:

  1. Megapixel cameras are capable of recording on their own. They generally have all of the same features that you would find in the rest of our Digital Video Recorders (DVR’s) and Network Video Recorders (NVR’s). You will be able to set up one IP camera on its own, or set up a few of them without ever needing an NVR to record its footage. A lot of megapixel IP cameras these days have the ability to record onto a micro SD card. It will save you some money if you’re looking to set up a surveillance system on a budget. However, you’ll ask yourself, so why would anyone ever need an NVR? That’s because in some application, you’ll need more storage space. If you set up the cameras on their own, you’re going to be limited to the amount you can record on a micro SD card. In turn, you’ll only have the capabilities to go back and view a couple of days of recorded footage as opposed to a couple of months. Also, NVR’s are generally going to act as a central hub for all of the cameras where recording each one on their own will make it harder for you if you’re looking to view all of the cameras at once. With an HD-SDI system, you’ll only be able to record the cameras if you’re using some sort of digital recording software or hardware.
  2. With an HD-SDI surveillance system, you’re going to need to have all HD-SDI technology. Unfortunately, you will not be able to use your current DVR with HD-SDI cameras. They transmit a different signal through the wires.
  3. Even though you may not be able to use your current DVR you will be able to keep your analog system wiring. This is a huge benefit for anyone who cannot re-wire their home or business. There are some situations where wires have been installed during the construction of a building and running new lines are near impossible without doing damage to the structure. In this case, it would be best to leave the wiring alone and upgrade your analog security system to an HD-SDI DVR and set of cameras. You’ll then be able to get the benefit of recording at megapixel resolution instead of being limited to D1.
  4. Even though it’s usually not really noticeable, megapixel systems have a bit of latency. Latency is also known as lag. If you’re viewing your video in real time, you may have a situation where you need to view the video exactly as its happening. Depending on how the network is set up, you may have a bit of latency (sometimes one second or more) and having an HD-SDI system will usually solve this issue when directly connected. You are then bypassing any network issues and recording the signal directly to and from the system without the inconsistencies of data packets being delayed.
  5. Many people purchasing a new system have a limited budget to purchase their security system with. HD-SDI generally ends up costing more money than a megapixel IP system. The chip needed to process the video in an HD-SDI system is generally more expensive than the ones manufactured for megapixel. Price has dropped considerably in the past few years and megapixel systems have become way more affordable these days in comparison to the costs of HD-SDI hardware.
  6. Even though an HD-SDI system is a bit more costly for the hardware, at the end of the day you may end up spending less because of ease of use. With a megapixel system, you may be stuck hiring someone with more of a technical background to set up your network and make sure that all of the cameras are connected correctly. Megapixel cameras each have an IP address and they all need to be set up correctly onto your NVR in order to begin recording each camera. You will end up having to choose between directly powering your cameras with a power supply or whether you want to use Power over Ethernet (POE) to power each IP camera. If you choose POE, you’ll have the benefit of just running one Ethernet cable for each camera all back to a POE switch, and then from there back to the NVR. This is where things can get confusing for most people who don’t deal with this type of network setup on a regular basis. Once you factor the cost of hiring a network technician, you may end up spending more money. However, with an HD-SDI system, every component is basically plug and play. You won’t need to worry about setting up each camera individually and at that point, running the wires will be your most difficult task.
  7.  One last thing you’ll need to consider is the reliability of your new surveillance system. If you ever have your DVR or Hard Drives fail on your HD-SDI DVR, your whole system will go down. You will no longer be able to record anything that’s happening on your property. However, if you’re using an NVR for your megapixel system and it crashes, at least you’ll have the peace of mind that you’re cameras are still capable of recording everything that’s happening for the next couple to few days depending on what type of memory card you have installed in each camera.

It seems that there are quite a few things to consider when trying to decide on HD-SDI VS Megapixel. If you think about it, it’s really not that hard of a decision to make. Personally, I would choose a megapixel IP system over an HD-SDI. It looks like the future is pointing to megapixel over HD-SDI because of all the added benefits between costs to reliability. Please keep in mind that HD-SDI still has its uses though. There are definitely some instances where it will be a benefit over a Megapixel IP system.

Fake Security Cameras

Written By:
Monday, March 5th, 2012

Deception, as far as security is concerned, plays an important role. Militaries have been deceiving opposing armies for centuries. Pioneers making their way west would routinely place gun barrels out the sides of the Conestoga wagons. This gave the appearance of multiple armed pioneers, when in fact no one was behind the rifle barrels. Bands of marauders, not knowing for sure, would not attack for fear of losing the battle and their lives. Wooden cannons made to appear as if real would be placed on battlefields. The opposing army many times would hesitate, and make a graceful exit from the field of battle. Using fake security cameras employs the same principles of deception that has been used for years.

Creating Doubt

Simply giving a criminal a moment of hesitation can be enough to cause them to move on. The deception must be well staged however. Spotting a camera invokes a visceral reaction in criminals and others up to no good. People that have committed crimes, and ones thinking about it, many times suspect others may be aware of their transgressions. Many call it a guilty conscience. However, it is not guilt from doing wrong. It is fear of being caught. Criminals when they see a camera lens staring at them as they make their way to a window or back door will stop. They immediately wonder if they have been spotted. They also wonder if the camera is high quality enough to identify them in the dark. Most will make a quick exit from the property.

The Ideal Fake Security Camera Is Real Except For

High quality fake cameras are real cameras without the electronic components. The housing is real and the cables are in their proper places. Ideally, you want one that has a red recording light and motion activation. The camera will come equipped with a battery pack that operates the motion sensor and recording light. However, placing a motion activated fake camera in a high traffic area will quickly deplete the battery. For the most part, homes would not have this type of activity. Businesses employing decoys would need to consider this when placing the cameras.

Make It Look Real and People Will Assume It Is Real

Placement and having the correct camera in the right spot is important. The cameras located outside need to be obviously designated for outdoor use. Criminals paying attention might begin to wonder. Use dome cameras at the front door. Real dome cameras conceal where the lens is pointed. People expect to see this type of camera at entrances. They also provide 360 degrees of coverage, and are tamper proof. Cameras placed with no obvious target area will raise questions about their effectiveness. Also, ensure the camera lens is not pointed at the ground, the sides of the structure or pointed straight up.

Play Your Part Well and Others Will Play Theirs

You can call placing fake security cameras a process of elimination. Would be burglars that are serious about maintaining their freedom will make on the spot assessments. Simply by driving by a potential target, a burglar will eliminate that house as a target, if security measures are obvious. The potential payoff is calculated by assessing risk. Like any professional contractor, the cost of the job is estimated by the amount of effort that must be put forward. A plumber, for example, will lose profit if they misjudge the effort and materials needed. A criminal that does this loses their freedom. Your part as a homeowner is to ensure the cameras always have fully charged batteries to operate the motion sensors and lights. Use widow decals and yard signs to warn of video surveillance.

Many Crimes are Crimes of Opportunity

Fake cameras are not just for the exterior of the home or business. You may have simply assumed that an intruder will never see the inside of the home if they leave after spotting cameras around the exterior. As a homeowner, stop and calculate how many people beside family members have been inside your home over the course of days, weeks or even months.

The cable installer is all over the home, they are in the basement, attic and every room inside. They are not professional criminals however. The large screen television or the new laptop may be more appealing than their sense of right or wrong. They overhear a conversation and realize the home will be vacant at a certain time. They plan and they decide to supplement their wages. Then they spot the camera mounted high in the corner with blinking red lights. It is a motion activated one. You as a homeowner have just thwarted a crime.

This is a prime example of why the cameras must be installed as if real. The cable installer, an electrician or any contractor has more mechanical knowledge than the average person does. You may think well they can spot a fake. They can if the fake camera is not installed properly. Quality fake cameras have real cables attached and many even come with AC adapters for use with household current. Mount the cameras in logical places and plug them in if applicable. Make sure the cables are run into the wall if they need to be. Criminals are aware of wireless cameras so the fact that cables are not protruding everywhere does not raise any questions.

However, they may look for a receiver. Make a point to keep the office locked when workers are present, if they need access be there to keep them from looking to closely at things. Have a file cabinet and keep it locked even if it is empty. Locked doors and secured cabinets all maintain the illusion. Individuals see the cameras and then find doors and file drawers locked they soon put the pieces together. This is doing your part as a security conscience homeowner. They have no idea if the receiver is in there. Unless they have access to your computer, they cannot tell if it is the receiver either. This is not to say that professional contractors are dishonest. The truth is many break-ins are done by individuals that have been in the home before, in some cases, more than once.

By no means, is any statement meant to indicate, or give the impression cable installers or any professional contractor is dishonest. The statement is simply to illustrate how many people may have been in a home over a certain period.

You may be thinking that if all of this has to be done why not just go ahead and install real ones. The cost is the reason why. Budgetary constraints are a major factor. The steps you take to maintain the illusion cost you little in dollars. The payoff however, is well worth the effort. The material costs are just a small percentage when compared to having real cameras professionally installed and monitored.

To maintain the deception, it is wise to install the fake security cameras yourself. The local contractor unwittingly may tell their colleagues or partner. Security is about keeping secrets. For example, armored car drivers never use the same route twice in succession. Their manifest will never have an inventory of contents. It is all about maintaining a security profile. The unknown will make intruders move on to the next house.

Criminals Do Not Want To Work Hard So They Spend Time Looking For Easy Targets

Your home says a lot about you, how it is maintained, what the lawn looks like and so forth. Cameras tell intruders you are paying attention. Fake Security CamerasThieves look for people who appear unaware of their surroundings. Toys or tools strewn about the driveway and yard tell people you may not be paying attention. Lack of obvious security is an open invitation. You have heard the term keeping up appearances. It applies to your security profile, as well.

An expensive looking surveillance system loses some of its impact when someone sees a cheaply constructed hollow core front door. The lock is not effective and easily defeated. The home profile as a whole must indicate you are aware of things, and are pro-active when it comes to security.

You have worked hard for your possessions and your family’s safety is the number one priority. It requires some effort to install fake security cameras and you must apply all the window dressing to go along with it. However, by not doing so you have set yourself up for an intrusion. Do not install cameras in trees with no obvious means of power where leaves and branches block the lens. This tells everyone you have thought about security but have only put a half-hearted effort into it. Tinkering around the edges when it comes to security is obvious to criminals. The efforts send a signal you are not serious, and frankly may not have a clue.

Like a Good Lie Good Deception Mixes In the Truth

Professional bodyguards put tremendous effort into deception. They mix the real in with the fake. When driving their client to and from places they use several cars all the same make and model. No one knows which vehicle to target. Anyone with ill intent is confused, overwhelmed and the majority of the time will give up any attempt.

Unlike money, you can have too many cameras, in some instances. Large estates are expected to have cameras in specific locations. Cameras would be mounted at the gatehouse or covering an entrance gate. The cameras would be mounted to screen visitors or capture vehicle license plates. Anyone would expect a large number of cameras to be present. There would be several covering the perimeter, the backyard, pool area and driveway. The cameras even if fake will still give the correct impression. However, having a large number of expensive looking cameras located around a modest dwelling can send the wrong signal.

It is perfectly acceptable to mix fake security cameras in with real ones that capture and record images. Many homeowners want a real camera to be able to see who may be at the front door. However, they realize most burglars gain access from back doors, upstairs windows and so forth. Decoy cameras can be placed in among real ones to increase your home’s security. Once again, place them in logical locations. One must cover the backyard and any doors or windows where anyone could gain entry. Homes having security gates at the end of their driveway would want one there, as well. These are logical locations and no one would question their position.

Parents regardless of economics want a camera to be able to monitor their child’s care while with a babysitter. They have prioritized, and placed the camera where they foresee the highest risk. In this case, fake cameras can be used in other areas of the home for the babysitter’s benefit. The babysitter has in all likelihood, determined the nanny cam is real. Therefore, others mounted high in the corners of certain rooms will be real to them, as well. This goes back to keeping honest people honest. Let them know you are paying attention and aware.

Prevention is the motivation behind fake security cameras. Let people know up front you are watching. No one wants to take the chance of being recorded committing a criminal act or even a very dumb act. Workers in your home when you are away may decide to help themselves to leftovers in the refrigerator. Seeing cameras mounted will stop this type of activity. Nosy neighbors will not snoop while your back is turned. This brings up another point. Do not tell your friends and neighbors. Once you tell a secret, it of course, is no longer a secret.

Part of good deception is being mysterious about certain things. You must be closed mouthed about your security measures. When people are not sure they hesitate, and many times will not follow through with what they intended. You must maintain appearances to have the proper security profile that will protect your family and possessions.

Deck Security Systems

Written By:
Monday, September 27th, 2010

If you own a boat or a yacht then a deck security system is a small investment that can yield large returns in the area of security and surveillance. In addition, a deck security system offers you the peace of mind of knowing that your craft or vessel is safe and sound.

There are many types of digital video security systems that are suitable for use on your boat’s deck. If your boat is docked at a slip that provides electrical power, or your yacht has its own on-board generator, then there is an even greater selection of security systems available for use.

Let’s consider these deck security systems as two different categories. One type requires external electrical power supply either in the form of typical house current or as DC (Direct Current) supplied by the boat’s battery and the other contains its own self-sustainable on-board power supply. We’ll discuss the latter type first.

There are many different types of digital video security camera systems that can function by using rechargeable batteries. These systems are usually an “all-in-one” type system where the camera and Digital Video Recorder are all one unit. These deck security systems are usually suited for smaller craft, where one camera can satisfactorily cover the target area for security surveillance. In addition to creating digital video files these cameras often are capable of taking digital still photographs as well.

These systems usually contain an infrared (called a PIR) sensor. The sensor acts as a switch to turn the camera on and off when movement is detected. This motion detection switching conserves the power supply so that only a small amount of electricity is needed to maintain the unit when there is no activity.

In addition, the Digital Video Recorder or DVR is normally some sort of flash drive that saves the digital video or still photographs to removable flash media such as a Smartcard, Flash drive, etc. Since the DVR uses flash media, these units have the advantage of being able to remove the storage media and view any recorded data on another device, such as a personal computer for example. The disadvantage with these units is that the flash drives have relatively small storage capacities (for example 2 to 8 Gigabytes) so recording time is limited compared to a typical DVR unit that may have hundreds of Gigabytes of storage. Nonetheless these units are still powerful security devices that can provide high quality images of any one trespassing or tampering with your boat.

Another type of deck security system that is similar to this system uses the boat’s DC current for power. These systems should also be motion activated to conserve energy usage. These units normally run off of 12 volts of DC current so they may possibly be powered by your boat’s battery or by an extra battery carried on board the boat dedicated specifically to the security system. These deck security systems may employ the Flash drive type DVR or may even contain a mini-hard disk drive DVR to record images.

Finally, for slips that provide external electrical power or for ships that contain their own on-board 110 volt AC (Alternating Current) power, standard digital video security systems can be used as deck security systems. These security surveillance system cameras can be mounted either on the deck of the boat or on supportive surfaces of the dock/gangway.

There are several different types of systems that may be used in these cases depending on the resources available, location of the dock, etc. For example, wireless digital video cameras can be used that transmit their video data to a corresponding receiver inside the home or marina. If the home or marina has broadband internet access, these systems can be easily networked using the internet so that the owner can monitor the boat area anywhere in the world there is internet access. This includes using 3G or 4G cellular smart phones to view the target area.

Depending on the equipment used, these deck security systems may be able to store up to four weeks or more of continuous video monitoring. These systems can also include audio recording, motion detection, and many other features as well.

Regardless of the deck security system you choose, make sure the camera(s) are designed for outdoor use so they are protected from the elements, especially water. Cameras used for this purpose should have an Ingress Protection (IP) rating of at least IP65.

What is an IP Rating?

Written By:
Wednesday, April 7th, 2010

This term can be confusing when dealing with security cameras because some digital security cameras can be IP networked cameras, which has nothing to do with an IP rating. An IP Rating also referred to as an IP Code, is an abbreviated form of the International Protecting Rating also known as the Ingress Protection Rating. For the benefit of clarity and distinction, an IP networked camera is a camera that can take advantage of Internet Protocol to transmit its video signals over a network or the internet.

An IP Rating or code is based on the International Electrotechnical Commission’s (IEC) international standard 60529. According to the standard, it “describes a system for classifying the degrees of protection provided by an enclosure. IEC 60529 is NOT a ‘product standard’ and does not cover enclosure requirements other than the ‘degree of protection’ provided. An IP rating is usually represented by two digits and may contain an additional optional letter.

An IP rating can be thought of as a more exact classification of the degree of protection offered from the security camera from intrusion by solid and/or liquid matter. The rating is usually expressed as “IP 65” or “IP 65M.”

The first digit represents the level of protection provided by the camera’s enclosure against solid objects foreign to the camera and against access to hazardous parts. The first digit can range from 0 to 6, with 0 meaning no protection at all and 6 indicating the greatest protection. The following is a list of each individual digit (level) and its classification based on EIC 60529:

0. No protection
1. >50 mm – any large surface of the human body but no protection against deliberate contact with a body part
2. >12.5 mm – fingers and similar objects
3. >2.5 mm – Tools, thick-gauge wire, etc.
4. >1 mm – Smaller wires, screws, etc.
5. dust protected – encroachment of dust is not entirely protected but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment
6. dust tight – complete protection from dust

The second digit represents the level of protection provided by the camera’s enclosure against water. The second digit can range from 0 to 8, with 0 meaning no protection at all and 8 indicating immersion possible over 1 meter in depth. The following is a list of each individual digit (level) and its classification based on EIC 60529:

0. No protection
1. dripping water – vertically falling dripping water drops will have no effect
2. dripping water when tilted up to 15 degrees – when a camera is tilted at an angle 15 degrees from its normal position vertically falling dripping water shall have no harmful effect
3. spraying water – Water falling in the form of a spray at an angle of up to 60 degrees will have no harmful effect
4. splashing water – Water splashing against the camera from any direction shall have no harmful effect
5. water jets – Water projected from a nozzle against the camera in any direction shall have no harmful effects
6. powerful water jets – Water projected from powerful jets will have no harmful effects
7. immersion up to 1 meter* – Harmful penetration of water will not be possible when the camera is submerged in water up to 1 meter in depth
8. immersion beyond 1 meter* – Harmful penetration of water will not be possible when the camera is submerged in water beyond 1 meter in depth
*Time and pressure are normally stated by the manufacture in addition to the IP rating for this designation.

The following letters can be appended to classify only the level of protection against access to parts by persons:
A. back of hand
B. finger
C. tool
D. wire

The following letters may be used to indicate the additional protection to the camera:
H. high voltage device
M. device moving during water test
S. device standing still during water test
W. weather conditions

Not every security camera manufacturer provides an IP rating, nor are they absolutely necessary. However, and IP rating provides a potential user a more specific means of determining the protection afforded to the camera from foreign objects. For example, many cameras are rated by their manufacturers as “Weatherproof.” However, a camera that is rated as IP 66 would indicate that it is impervious to dust and that water projected from power jets will not cause harm to the camera and its parts.
