HD SDI technology allows you to connect 1080P and 720P CCTV cameras using existing or new coax. This gives the benefit of HD resolution without the need to run these images over an IP network. The obvious advantage is that true broadcast quality HD can be viewed and recorded without the need to compress the images in order transmit across a TCP/IP solution. In addition no training or IT knowledge is required. This makes this technology a favorite with many existing CCTV installers especially in the UK where we have so many existing analogue CCTV systems that need upgrading and enhancing. HD CCTV is the ultimate answer to all our issues with poor picture quality from analogue cameras.
