Eliminates costly and bulky coaxial cable
Sends composite baseband video & power over UTP up to 250m
Real-time transmission
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.
VPB45 PASSIVE VIDEO & POWER BALUN (RJ45 JACK)
The VPB45 has a mini-coax pigtail lead which allows quickmounting 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 VPB45 eliminates costly and bulky coaxial cable, allowing live CCTV color video signal up to 400m (1300ft).
The superior interference rejection and low emissions ofthe VPB45 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 VPB45 has built-in surge suppression to protect video equipment against damaging voltage spikes. Its crosstalk and noise immunity ensure quality video signals.
Basic application: Direct connection with monitor
Simple application: Four cameras connected to DVR
Full CCTV application: Many cameras to DVR via powered hub.
