2.1.4 Cable installation

Please make sure, that the coaxial cable is not squeezed at any position.

Also the max. bending radius defined by the cable manufacturer should be considered.

General rule: maximum bending radius = 10 x outer cable diameter

Bending creates pressure on the center conductor, causing it to move through the dielectric toward the inside of the bend. This affects impedance and return loss and reduces the maximum possible cable length.

Please try to avoid any BNC - adapter or any connectors in the BNC cable.

Looping HD-SDI signals by BNC T-connectors to other devices is not possible.

2.1.5BNC-plug

Also the BNC - plug plays an important role for clear HD-CCTV signal transmission.

Standard BNC plugs for CCTV have a quite high attenuation and may cause return losses due to reflection effects.

We recommend using of HD-Video approved BNC plugs.

2.1.6Extended cable lengths with repeater EHA-RPT / converter EHA-

SRX

The maximum cable distance between camera and DVR and DVR / repeater can be doubled by installing EHA-RPT in the video line. EHA-SRX is a combined HD-SDI cable extender and HD-SDI to HDMI converter.

The HD-SDI output of EHA-SRX allows adding one more complete coaxial cable length.

* max. coaxial cable depends on installed cable type
