BZBGEAR 25ft 75-Ohm SDI Siamese BNC Cable

This 25 ft BNC cable combines a 75-ohm shielded coaxial line with an 18-gauge two-conductor copper wire for DC power or RS232/485 control. It supports 1080P video at 60 Hz and is 3 GHz sweep tested for reliable signal integrity up to 100 m.

Suits Installers Needing Power and Video in One Run

Ideal for permanent or temporary setups where a single cable must carry 3G-SDI video and low-voltage power or serial control to cameras. Not suitable for buyers who require 4K or higher resolution transport, longer runs beyond the rated distance, or non-BNC connector types.

3 GHz Sweep-Tested 75-Ohm Coax

The defining specification is the 3 GHz sweep-tested 75-ohm coaxial construction paired with an 18-gauge stranded copper pair. This combination determines whether the cable meets the bandwidth and power-delivery needs of a specific 1080P SDI installation.

Questions about this item

What BNC-equipped devices do I need at each end for this 25 ft 75-ohm SDI cable to carry video?

Connect it between any 3G-SDI camera, monitor or switcher that accepts a BNC connector and supports 1080P60 signals.

Can I leave my existing RS-232 or RS-485 control wiring in place and run it through this siamese cable instead?

The integrated 18-gauge stranded copper pair is designed for DC power or RS232/485 signals, so you can consolidate control lines into the same 25 ft run.

How do I confirm the 3 GHz sweep-tested cable is delivering a clean 1080P picture after installation?

Check the monitor for a stable 1080P60 image without sparkles, dropouts or colour shifts — the woven shield and sweep test are intended to eliminate those artifacts.
