The VE810 HDMI Extender extends your HDMI display up to 60 m from your HDMI source device using two Cat 5e cables. In addition, VE810 is equipped with IR signaling pass-through which allows the IR channel to control from the remote to the local unit, to control the HDMI source, or from the local to the remote unit, to control the display device. For flexibility and convenience, the VE810 setup requires only one power adapter for both units. The VE810R remote unit will function without the need for an additional power adapter because it will be powered by the VE810 local unit.
