2.1.1Understanding HD-CCTV signals and wiring

Even if EverFocus HD-CCTV equipment uses coaxial cable and BNC type plugs similar to standard CCTV technology - the requirements for wiring and cable types are some different.

This chapter explains some basic facts for HD-CCTV signals and cable requirements.

2.1.2HD-CCTV signal

In result to the high resolution and uncompressed image transmission from the camera high frequencies are used for HD-CCTV signal transmission.

EverFocus HD-CCTV technology is mostly based on the SMPTE-292M standard, which defines HD-SDI (High Definition - Serial Digital Interface) video transmission.

In classic CCTV video standards PAL/NTSC the frequency bandwidth is < 6MHz for high resolution cameras.

HD-CCTV works with up to 1.5 GHz, so this technology requires ~ 250 times higher frequency than PAL/NTSC based CCTV.

The figure below shows the basic timing and signal levels of a full HD (1920x1080) signal:

Timing of HD-SDI signal ("Eye"-diagram)

The diagram shows the total difference of HD-CCTV signals to classic NTSC or PAL signals.
