 IP-based Surveillance System  vs HD-SDI technology


One of the main benefits of HD-SDI technology is that there is zero loss of image data and zero latency when viewing images, HD-SDI technology is increasingly concerned by the industry.


However, in a HD-SDI based video surveillance system, an independent subsystem consist of a HD-DVR and several cameras connected, Failed HD-DVR will lead to all related surveillance points ineffective. In a network camera based video surveillance system, every HD IP Camera is an independent subsystem, there is no depot point, so IP-based cameras are with higher reliability for security surveillance systems.
