The GBC 67.3750.60 BNC balun enables video surveillance signals to travel over Cat.5 Ethernet cable instead of coaxial cable, reducing installation cost and complexity. It supports AHD, CVI, and TVI camera standards and transmits the video signal at distances up to 300 metres without loss or interference.

Resolutions up to 8Mpx 4K are supported at distances up to 250m. Connection is made via BNC extension on one side and RJ45 screw terminals on the other — at both the DVR and camera ends. Built-in 4KV surge protection guards against voltage transients on the cable run.

Key Features
