Network cameras (or Network IP Cameras as they are also known) are a revolutionary concept for security systems and a whole variety of other applications. Network cameras, as the name suggests, are run via existing computer networks, such as LANs, WANs and even over secure systems on the Internet using a series of IP numbers in a similar way computers in a computer network might do

 

Network cameras can do away with the need for an independent system of cables that traditional (analogue) CCTV camera systems require. In addition they allow storage of recordings on standard PC or Server hardware, or dedicated storage equipment known as a Network Video Recorder, each of which is capable of storing vast quantities of data.
