Commercial Video Surveillance Systems by NSS
Video surveillance has been a popular security tool for years. And thanks to new breakthroughs in technology, security camera systems are more effective than ever before. This past year NSS has had the privilege of working with some local schools to beef up their current systems and provide higher levels of security. We now have the technology to track any student any where at any time in the building through a system called video analytics. (Analytics in Action).
Banks, office buildings, retail stores, and countless other end-users depend on the protection provided by video surveillance. The cost of a high-resolution camera / hard drive recorder based camera system has dropped dramatically over the past few years. We are seeing more and more small business owners install systems that only very large companies could afford before.
If you own a business of any size, you cannot afford not to have some level of video surveillance. We are constantly evaluating camera distributors and suppliers in an effort to provide you with the highest quality equipment at the lowest prices. Give us a call - we think you will be surprised at how affordable a commercial security camera system can be. (770)-216-1997
Cameras: 1/3" Sony CCD
This is the heart of the camera and is what translates what the lens sees in video, Sony CCDs are the "standard" for CCTV applications and you will find that many companies sell inferior cameras with smaller 1/4" CCD chips at the same prices for higher profit margins
Lens type and focal length --
Lenses range from 2mm to 50mm for most applications and the particular lens selection will determine how wide or narrow the camera's field of vision will be. A camera covering an alleyway should have a completely different focal length than a camera that covers a parking lot.
Day/Night --
"Night Vision" can be handled by cameras in two ways, the first is with IR beams and the second is with a low lux capable lens or slow shutter feature. There are pros and cons to each depending on the application.
Wide Dynamic Range --
generally an upgrade option, WDR cameras provide a clear image in extremely bright environments or where glare is a problem. It is generally used when it is important to distinguish minor details from a scene.
IP based cameras --
IP cameras are integrated into a computer network and can provide true high definition video images, this is a new technology and generally reserved for commercial applications where image quality must be of the highest caliber. Depending on the camera, still images pulled from the video are equivalent to those taken with up to a 10 mega pixel digital camera.
