Digital Video Recorder.

In November 2012, Dahua technology released analog high-definition transmission interface technology-HDCVI(High Definition Composite Video Interface), with self-owned intellectual property right. HDCVI technology is a HD video transmission method, based on existing RG-59 or RG-6 coaxial cable. It can achieve long distance HD video signal reliable transmission at low cost via low general coaxial cable. In the practical application, HD-SDI subsystem requires high transmission medium, while HDCVI is suitable to the long distance, low cost transmission medium and complex deployment situation.

Network Video Recorder.

An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet.
