HDMI Extension Solution for Professional Audio/ Video installation

HE04SEK is a 1-in-4-out HDMI distribution amplifier that can use CAT5e (or better) cables to extend and split the signal for up to 70M. Plugin your HDMI source and you can easily use cost-effective network cables to send 4 HDMI signals to the remote ends. The transmitter (HE04SET) has a built-in HDMI loop-out port that can use to connect an extra HDMI display or the next transmitter to daisy chain up to 3 pcs and split up to 12 HDMI signals. Moreover, the receiver (HE01SER) is a dongle design, allowing you to directly connect an HDMI monitor without applying an actual HDMI cable. It's the perfect solution for bars, restaurants, churches, meeting rooms, classrooms, and surveillance rooms that require signal extension and distribution at the same time.
