Destription for SDI CCTV system and IP CCTV system


CCTV Digital Image Distribution Technologies HD-SDI CCTV HD-SerialDigital Interface came from the SDI Broadcast standard developed by SMPTE, for Transmitting video.

HD-SDI is available in the CCTV market for transmission of high definition images over existing RJ59U analog infrastructure, or high end Coax cables such as RJ6 or RJ11.

By stating 'Analog' we often mean "standard" resolution: either 640x420 4 CIF or D1 is for 720x486 resolutions.  HD-SDI supports real time HD resolution with 30fps(frame per second)for 1280x720p or 1920x1080p. Large numbers of manufacturers have been displaying several models of HD-SDI cameras at CCTV trade shows throughout 2011 & 2012.

The future is bright for HD over Coax technologies and reflects the growing demand for

uncompressed high definition technologies.


IP cameras stream live video via digital packets across an internet protocol network such as a LAN (Local Area Network) or the Internet. It means that video streams can

be accessed remotely, via a smartphone, tablet or other networked devices, and can be

stored remotely.

IP CCTV systems do not require local recording, they can transmit their images across

Local Networks, or the Internet, where they can be recorded, viewed and managed.

IP cameras offer high detail precision with Megapixel resolution, at least 3 times better

quality than standard analog cameras.
