Summary: Works reasonably well. Biggest problem is signal interference from other electronic and 2.4 ghz devices. My neighbor has a wireless router that really messes with my Terk...I can tell when the router is on, the picture gets a lot of \"static\". The Terk does allow you to adjust the \"channel\" that it transmits on...that helps, but it seems like sometimes it's a losing battle. When it works, it's great, but the interference factor can be frustrating.

Summary: First, let me describe what I was attempting to do, since it wasn't your average hookup, probably. I was attempting to run my Cable TV wire coming into my house, into my HP MediaCenter PC Tuner card. Then, from my Tuner card, I wanted to run out using S-Video to the Terk transmitter device. From the Terk receiver, I wanted to run into the television. The goal: to record TV using my PC and also use my picture in picture feature to compute and have TV on at the same time, all without having to run wires across the room to my 55\" sony. I reached the goal, but not with this product and not without wires.

After MUCH anguish at realizing this product did NOT have an s-video IN port, I was stuck. The S-video is where you're going to get the highest quality picture, next to VGA (monitor) inputs. So, I had to go buy a modulator (walmart or best buy $30) that I could plug in an S-video cable, and plug \"out\" a composite (yellow, red, white) cable that would go to the Terk transmitter. This worked, but there was serious loss in picture quality (looked uncontrasted, too soft and fuzzy in appearance), especially when computing. There was really no comparison when looking at the wireless versus wired options in this scenario; the picture was just to clear compared to the use of the transmitters.

Bottom line: If the picture quality were maintained, I would have kept them. Perhaps for your application, there would be no signal degradation. For just shooting cable from the living room to the bedroom, these would probably do a good job. But to avoid having to buy extra parts, make sure that what you're transmitting from has composite \"out\".

Summary: Used in 2 separate rooms which tried connecting a Digital Recorder to a TV in another room. The distance was around 20 to 30 feet apart. I am not sure if concrete walls makes a difference. There was too much interference, even tried all 4 different channels that it came with. It appears to work decently if the transmitter and receiver are in line of sight which I had tested.
