IP Video Surveillance System is a digitized and networked version of closed-circuit television (CCTV). In an IP Video Surveillance System, an IP camera records footage and the resulting content is distributed over an IP (Internet Protocol) network.

Digitization offers a number of benefits over traditional analog (CCTV) such as: improvement of search capability, greater ease of use, better quality images and no degradation of content over time, ability to record and play simultaneously, and the ability to compress content for improved storage. Likewise, adding networking capability to digital CCTV provides additional benefits including: improved ability for remote viewing and control. Anyone on the network can potentially see video from any camera connected to the network. IP storage makes it possible to store data in any geographic location. It also offers a greater ease of distribution. An image of crime suspect, for example, can be immediately distributed to officials. Nevertheless, the ability to connect to email and other communications systems so that alert can be sent automatically.
