This is the receiver-only unit for the LENKENG HDMI 1.3 extender over IP system, sold separately from the transmitter kit (model HDMIC373). It receives an HDMI signal transmitted over a single Cat5e or Cat6 network cable, supporting distances up to 100m on Cat5e or 120m on Cat6. Because one transmitter can feed multiple receivers on the same network, this unit is typically bought as an add-on when extending an existing HDMI-over-IP setup to an additional display. It supports standard HDMI features including 1080p, deep colour and lip sync.
