Welcome to the
If you need basic technical information
Around the world, the vast bulk of installed CCTV cameras are conventional industrial "box" types. With almost all now using CCD imagers, from 1/4 to 2/3 format and with a range of resolutions and sensitivities, the choice is actually quite mind numbing. (there are actually cameras being used outside of the UK using still smaller imagers, 1/6th CCD being available in the Far East, but with significant technical limitations)
Interestingly enough though, cost isnt always a reasonable benchmark for performance. Some absolutely cracking (very good) cameras can be bought for relatively little cost, whilst some hugely expensive units, still have the capacity to disappoint.
Most cameras are capable of accepting a wide range of interchangeable C or CS mount lenses, although some now have a half decent varifocal or zoom optic fitted as standard.
Seriously though, to get the very best from any camera does require a modicum of appropriate knowledge, and so Doktor Jon has sought to explain in some detail, a few of the more complex technical terms elsewhere on this site.
NETWORK AND SERVER CAMERAS
Whereas conventional cameras are only capable of putting out a composite (CVBS) video signal, Network and Server cameras are specifically designed to output computer data signals, that are normally displayed through a web browser such as Internet Explorer.
