The standards for electronic security are constantly changing. Many times, keeping up with the different types of video surveillance systems that are available can be confusing, so here is a simple break down of the three most commonly used surveillance systems today:
Analog Camera Systems –This is an older technology and is not preferred by clients as often because of its video quality. Analog systems provide resolutions up to about 720 TVL. Most people don’t want to see analog systems anymore because we become accustom to seeing HD on our TVs, computers, and even phones. However, they are fairly low in cost, and also are simple to design and install. These systems are a good place to start learning about video surveillance.

HD Analog/CVI– Composite Video Interface or CVI is the newest technology in surveillance systems. It is simple and cost effective. The main idea behind these systems is that you are able to record megapixel cameras- up to 1080P- using coaxial cabling rather than the more expensive Category 6 cabling in conjunction with network switches and routers. Although the resolution only goes up to 2 megapixel, this is a great cost-efficient way to upgrade your system’s resolution without even needing to re-run wire.
IP/Megapixel Camera Systems– IP/Megapixel is a more current form of video surveillance. The price for these systems has dropped dramatically in recent years, so many clients are interested in this than anything else. These systems use category 6 cabling and Power over Ethernet (PoE) to provide extremely high resolution images, ranging anywhere from 1.3-40 megapixels! Another great feature of IP megapixel systems is that the recorders are usually expandable to fit any sized business or facility. Some systems even work in conjunction with your access control systems.
