The single VGLI (Video Ground Loop Isolator) balun is an HD video transform filter for HDCVI/TVI/AHD. This is built in a highly balanced mode of video transmission, which is immune to interference from many sources of noise including: Data signals, other video signals, nearby power, ringing telephones, fluorescent light and transformers, etc.

These support PTZ data control, supports 720p, 1080p and 4K resolution, eliminates problems such as image tearing, cross-talk, rolling, etc. and because it’s passive, there’s no need for a power supply.
