Here are some things you should consider when purchasing your security camera system:
Cameras: 1/3" Sony CCD: This is the heart of the video surveillance camera and is what translates what the lens sees to the video you see on your recordings, 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. 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: This is usually 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 camera: 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.
