DOSS 2012 CCTV Balun Range (.pdf)


The VPBPP has a mini-coax pigtail lead which allows quick mounting onto fixed cameras and allows in-camera mounting in most dome cameras. The 8-Way Push Pin terminals for UTP cable enable quick and simple installation. Working in pairs, the VPBPP eliminates costly and bulky coaxial cable, allowing live CCTV color video signal up to 400m (1300ft).

The superior interference rejection and low emissions of the VPBPP 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 VPBPP has built-in surge suppression to protect video equipment against damaging voltage spikes. Its crosstalk and noise immunity ensure quality video signals.

Example scenarios

Basic application: Direct connection with monitor

Simple application: Four cameras connected to DVR

Full CCTV application: Many cameras to DVR via powered hub.

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

The passive (non-amplified) baluns allow transmission of realtime CCTV video signals and power over cost-effective Unshielded Twisted Pair (UTP) cable, without any compression, loss or signal degradation and without the need for 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.

50m / 160ft 13.5V (1.5V) 15.5V (3.5V) 17.0V (5.0V)

22.0V (10.0V)

150m / 500ft 17.0V (5.0V) 22.0V (10.0V) 27.0V (15.0V)
200m / 650ft 18.5V (6.5V) 25.5V (13.5V) 32.0V (20.0V)
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)
