The DOSS Range of UTP Video 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 over cost-effective Unsheilded Twisted Pair (UTP) cable, without any compression, loss or signal degradation and without the need for extra power supplied to be installed. Baseband (composite) signals of any type are supported.

It is compatiable with all HD-TVI, HD-CVIand AHD analog camera.

Male BNC of BVB4100PHD allows connection directly to the camera or DVR. Tool-less push pin terminals allow easy
and quick connection of UTP cable output. Working in pairs, the BVB4100P eliminates costly and bulky coaxial cable, allowing live CCTV color
video signal up to 400m (1300ft). The BVB4100PHD is also compatible with other Video Balun products from DOSS.

The superior interference rejection and low emissions of the BVB4100PHD 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 existingcable infrastructure. The BVB4100PHD
has built-in surge suppression to protect video equipment against damaging voltage spikes. Its crosstalk and noise immunity
ensure quality video signals.
