Classifying an IP Surveillance Camera

http://www.supercircuits.com/Security-Cameras/Network-IP-Security-Cameras/ An IP surveillance camera can send and receive data via the Internet or a computer network. IP surveillance cameras are classified into two types, centralized and decentralized. A centralized IP video camera requires NVR (Network Video Recorder) to handle the recording.
