HDBaseT is the technology used for long distance transmission of lossless signals, resulting extremely low latency & giving the best picture quality.

In normal extenders, if you extend your signals up to some extend, the quality of the signals will degrade & you may find some latency issues. HDBaseT is the lastest standard which provides extending your signals to the longer distance without degrading the quality of the signals & with 0 latency.

We recommend you using a shielded CAT6 cables for optimum performance.

Our all the extenders supports IR Frequency & the devices using RF frequency will not be compatible with our products.

The IR Blaster/Emitter should be connected to the IR out port on the Transmitter and the IR Receiver should be connected to the IR in on the Receiver.
