SDI (Serial Digital Interface) is a standard for digital video transmission over coaxial cable. The most common data speed is 270 megabits per second (Mbps). Standard 75-ohm cable is used. This is the same type of coaxial cable used in traditional analog CCTV system installations. Upgrade old CCTV system to HD CCTV system becomes simple and easy.

The greatest advantage of choosing SDI camera is the real-time performance. There is no any delay to display the real word video over the long distance cable. You can extend your vision up to 30KM through optical fiber cable.

The greatest advantage of choosing ILDVR solution is that iHVR system always adopts up-to-date PC techbology. In other words, iHVR has quadruple capability than embedded system. For example, iHVR-C4000 can support up to 16 SDI cameras meanwhile other DVR system only support max. 4 SDI cameras.
