Analog high-definition CCTV cameras
In recent days, the request for analog high definition has subsequently than cold than the peak. Many manufacturers have started manufacturing analog high definition CCTV cameras.
This article compares some of the analog tall definition technologies spacious to us.
HD-SDI (High definition – serial digital interface)
The definitely first to begin tall definition in analog is HD-SDI. HD-SDI is rosy of producing full HD or 1080p unchangeable. However, the high price and compatibility of them have pushed them to the last place.
HD-SDI was used in the to come days of camcorders. The only gloss they were not introduced in CCTV cameras is due to the fact that they were enormously costly.
HD-CVI (High definition composite video interface)
HD-CVI or high definition composite video interface is the latest adding to the HD CCTV system. This technology is developed by Dahua.

HD-CVI with makes it easy to transmit audio, video, and data taking into account one single coax cable. HD-CVI has zero latency and this is other beatific advantage compared considering IP technology.
HD-TVI (High definition transport video interface)
