Binary B-200-1CAT-HDIR Receiver — engineered by SnapAV. $45.00 OBO What it is: It’s part of an HDMI over Cat5/6 extender system. It receives HDMI video/audio signals that have been sent over a long distance using an inexpensive Ethernet cable (CAT5e, CAT6). Instead of running an expensive, bulky long HDMI cable, you use network (CAT) cables between the transmitter (sending unit) and this receiver (receiving unit). This model also supports IR (infrared) signals, so you can control devices like a Blu-ray player or cable box remotely from the receiving end. What it’s used for: Sending video from a source (like a DVR, streaming box, Blu-ray player) to a distant TV or projector. Commonly used in home theaters, commercial displays, conference rooms, etc. Example: Your DVR is in the living room, and you want to watch it on a TV in your bedroom 80 feet away. Instead of running a thick HDMI cable, you use a transmitter + receiver pair like this over CAT6 wiring. How much it costs: The Binary B-200-1CAT-HDIR system (transmitter + receiver together) originally retailed around $200–$300 USD for the kit. A single receiver (like this one) by itself sells for $80 USD if bought used (in excellent condition). _____________________ Important: You need the matching transmitter for it to work. It’s not useful alone unless you already have the paired transmitter.
