These boxes simply carry HDMI and IR (remote control information) of a single blue cat6 data cable.
Depending the model they can carry 20-100m so this solves the issues with long run HDMI cables not to mention the cost of a 20m HDMI cable to carry Ultra HD 4K. You may need 4 inputs available at 4 different TV’s all in HD quality. This is achieved with a Matrix and can be controlled with one command.
We carry a huge stock of these boxes to solve all installation demands.
