  • Transmit eight channels over one UTP cable
  • Rejects common-mode noise up to 60 dB from 15 kHz to 6 MHz
  • Matches 100 Ω UTP to 75 Ω BNC without power
  • Fits standard 17 inch rack at 1U height
  • Weighs 2.3 lb for easy mounting

8-Channel Passive Video Transceiver

The Bluecctv BL-EV08P-1U combines eight passive video transceivers in a single rack-mountable chassis. It converts unbalanced 75-ohm BNC signals to balanced 100-ohm UTP transmission over CAT5 or higher cable. The unit handles frequency response from DC to 6 MHz with 60 dB typical common-mode rejection between 15 KHz and 6 MHz.

Installers running multiple cameras over

This device suits installers who need to run eight analogue video feeds over existing twisted-pair infrastructure without external power supplies. It is not intended for installations requiring active signal amplification, Power over Ethernet integration, or transient voltage suppression on the UTP side.

Passive 8-channel UTP transmission over CAT5

The transceiver uses 24 AWG UTP cable with a maximum differential capacitance of 62 pF per metre and a DC loop resistance of 18 ohms per 100 metres. Impedance matching is fixed at 100 ohms on the RJ-45 side and 75 ohms on the BNC side. The chassis measures 17 x 3.3 x 1.7 inches and weighs 2.3 lb.

Questions about this item

How is the 8-channel passive balun installed in a rack, and which step is often missed?

Mount the 17" x 3.3" x 1.7" unit in a standard 1U rack space, connect each camera to a BNC port and each UTP run to an RJ-45 port, then verify the 75 Ω to 100 Ω impedance match on every channel — the step most often missed.

What maintenance will the BL-EV08P-1U need over time?

Inspect the RJ-45 and BNC contacts for corrosion, re-terminate any CAT5 links that exceed 18 Ω per 100 m loop resistance, and confirm the 60 dB common-mode rejection remains intact after cable moves.

What limit appears first when the transceiver runs continuously with long cable runs?

The 6 MHz frequency response and 62 pF/m capacitance of the UTP cable attenuate high-frequency video detail first, especially on runs approaching the 18 Ω per 100 m resistance ceiling.
