Features

The DOSS Range of UTP Video+Power+PTZ Baluns allow you toconnect 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. Baseband (composite) signals of any type are supported. 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. With PTZ/​Data transmission built-in, you can still control all your PTZ cameras and other devices withoutany extra baluns or cables.

VPPB45 PASSIVE VIDEO, POWER & PTZ BALUN (RJ45 JACK)

The VPPB45 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 connection for UTP cable, enabling quick and simple installation. Working in pairs, the VPPB45 eliminates costly and bulky coaxial cable, allowing live CCTV colour video signal up to 400m (1300ft), power transmission up to 250m (750ft) and PTZ data up to 200m (600ft).

The superior interference rejection and low emissions ofthe VPPB45 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 VPPB45 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)
