A network I P Camera is a stand-alone device which allows a user to view live, full motion video from anywhere on a computer network, even over the internet, using a standard web-browser.
until very recently, video security and surveillance was accomplished using closed circuit television or cctv. This technology included analog cameras, coaxial cable and video tape recorders. Video security and surveillance started entering the digital age with the advent of ccd sensors which digitized image capture in the camera. However, transmission was still analog via coax to analog vcr's. The next step was the introduction of digital video recorders (dvr's) connected directly to analog cameras, which made storing, searching and retrieving video much more efficient. Pc's were then introduced for display of the images through a modem or network connection to the dvr.
