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.
