Bluecctv BL-EV04P 4CH Passive Balun Transceiver
The Bluecctv BL-EV04P is a 4CH passive video transceiver designed to carry CCTV signals over unshielded twisted-pair cabling. It connects four BNC cameras to a single CAT5 or higher UTP link without external power. The unit measures 3.2" x 3.2" x 1.1" and weighs 0.2 lb.
Installers running multi-camera sites over
This device suits installers who need to run four analogue video channels over existing or new UTP infrastructure up to the supported frequency range. It is not for buyers who require active signal amplification for longer cable runs. It is not for systems needing built-in transient protection or separate power distribution over the same cable.
100 ohm UTP to 75 ohm BNC impedance matching
The transceiver presents 100 ohms on the RJ-45 side and 75 ohms on each BNC port, with common-mode rejection of 60 dB typical from 15 kHz to 6 MHz. The DC loop resistance is 18 ohms per 100 m on 24 AWG wire. This impedance match is the specification that determines whether the balun integrates cleanly with the camera and recorder ends.
