Overview
BP8CH12V8A 8CH BALUN HUB W / BUILT IN 12VDC / 8.5A POWER SUPPLY AND 8X VPB45 BALUNS
With the same features and abilities as the DOSS Video+Power baluns, and the convenience of a single box withbuilt-in power supply, the BP8CH12V8A is able to supply 8x CCTV cameras with 12VDC, up to 1A each. Video received from the transmitting baluns is output via 8x Female BNC connections straight into your DVR or other recording device.
Features 8x 8P8C (RJ45) connections for UTP cable, enabling quick and simple installation. Working with the DOSS Passive Video+Power Baluns (included), the BP8CH12V8A eliminates costly and bulky coaxial cable, allowing live CCTV colour video signal transmission up to 400m (1300ft).
The superior interference rejection and low emissions ofthe BP8CH12V8A 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 BP8CH12V8A has built-in surge suppression to protect video equipment against damaging voltage spikes. Its crosstalk and noise immunity ensure quality video signals.
Example scenarios
4-8 cameras connected to DVR via powered hub
Many cameras to DVR via powered hub w / long runs.
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 Unshielded 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.

|
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 onmake and quality of cable) |
