Alfatron TPBHD70-R



Alfatron TPBHD70-R

The ALF-TPBHD-70-R is a mini-size HDBaseT Receiver. HDBaseT technology is used to transmit high-resolution 1080p / 4k signal from a transmitter to the receiver via a CAT6a cable at a distance of up to 70m (230 ft) / 40m (131 ft). Moreover, the TPBHD-70-RS RX supports CEC, bi-directional RS232 and IR control, with PoH function.


Product Features
