Features

The DOSS Range of UTP Video+Power Baluns allow you to connect your CCTV system using cheaper, thinner, lighter andmore readily available CAT5E cable rather than expensive andbulky RG59U cable.

The passive (non-amplified) baluns allow transmission of realtime CCTV video signals and power over cost-effective Unsheilded Twisted Pair (UTP) cable, without any compression, loss or signal degradation and without the needfor extra power supplied to be installed. Sending camera power over the same twisted pair as video means less cabling, and no power supply required to be installed near to the camera. Baseband (composite) signals of any type are supported.

VPB45PCD PASSIVE VIDEO & POWER BALUN WITH DC-DC CONVERTER (RJ45 JACK)

The main feature of the VPB45PCD is its ability to convert 24-28VDC to regulated 12VDC at the camera, allowing the system to be highly tolerant of voltage drop in the cable. The VPB45PCD has a mini-coax pigtail lead which allows quick mounting onto fixed cameras and allows in-camera mounting in most dome cameras. 8P8C (RJ45) Jack connectionfor UTP cable enabling quick and simple installation. Working in pairs, the VPB45PCD eliminates costly and bulky coaxial cable, allowing live CCTV color video signal up to 400m (1300ft).

The superior interference rejection and low emissions ofthe VPB45PCD allow signals to coexist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of a shared or existing cable infrastructure. The VPB45PCD has built-in surge suppression to protect video equipment against damaging voltage spikes. Its crosstalk and noise immunity ensure quality video signals.

300m / 1000ft 22.0V (10.0V) 32.0V (20.0V) 42.0V (30.0V)
eg: to supply a camera that requires 12VDC/​0.5A, over a run of 150m cable, you require an initial transmission voltage supply of 17.0VDC (to account for 5V voltage drop over cable)
Note: based on typical CAT5e cable (will vary on make and quality of cable)
