(1) protection of existing cable investments;

(2) video transmission almost zero delay;

(3) adopting a global unified standard;

(4) to ensure that 100% of the plug and play;

(5) to provide 1080 resolution full frame HDTV uncompressed video.

In contrast, the image captured by a million pixel IP camera can be transmitted through compression, and does not have the above (1) - (4) advantage.

Secondly, why the HD-CCTV camera market in the next few years can rise rapidly?

There is no mention of the HD-SDI interface. HD-SDI HD serial digital interface for short, was originally developed for the professional HDTV market, has become the standard protocol in the global HDTV market, are widely used in professional audio-visual equipment market, a high degree of maturity. Therefore, the use of HD-SDI interface on the HD-CCTV camera to shoot HD video lossless transmission has become the only option.

As the PC interface standardization brought about by the revolution, HD-SDI will also bring revolutionary changes to the security industry.

However, the industry is puzzled by the problem is: HD-SDI cable transmission distance is not far away. In fact, in the radio and television industry, in order to solve this problem, many manufacturers have introduced the extension, can be a good solution to this problem.

Again, according to IDC forecasts, in the global scope, the main growth in demand for IT equipment from: banks, government, retail, transportation and public utilities in these five areas, including the input of the HD camera.
