The Doss VPB45HD is video & power transmitter and receiver that allows the transmission of real-time CCTV HD video and power signal via cost-effective UTP unshielded Twisted Paired cable.

The Doss VPB45HD is compatible with all HD-TVI, HD-CVI and AHD analogue cameras. Used in pairs which eliminates costly and bulky coxial cable.

The superior interference rejection and low emissions of the balun allow video & power signals to coexist in the same wire bundle as telephone, datacom or low-voltage power circuits. Also it has built in surge suppressor to protect video equipment against damaging voltage spikes. Its crosstalk and noise immunity ensure quality video signals.

Which is the best cable for use with these baluns?

We recommend to use Unshielded Twisted Paired (UTP) wiring from 24AWG through 22AWG. Individually shielded pairs should be avoided as they reduce the operating range of the systems drastically.
