Wireless Audio/Video Sender/Receiver System Review

Average Reviews:

(More customer reviews)Okay, bear with me as I unpack the product - first, two sets of RCA cables for stereo audio and composite video, the receiver, the transmitter, a tiny instruction manual, and ... a power supply? No. Just one cable that plugs into the DC input of one of the two units with two exposed wires on the other end that I can, well... solder to a 12V power supply I have lying around somewhere?!
It may not be apparent from the product description, but this unit does not come with its own power supply! It's up to you to provide 12V to each of the two boxes. How many Ampere? How would I know! The instruction manual just says to hook up "any 10-15V power supply".
Well, if you have a couple of general-purpose power supplies in your garage, you can try the product itself. And you'll regret that. The sound quality is a joke, you'll essentially just hear static. I tried putting the two units next to each other with the antennas effectively touching each other, and it was still just noise with a bit of sound. At some point - after choosing the right channel, and when aligning the antennas with the moon, you will hear something, but the quality is still horrific, with a tiny frequency range that makes it sound like you're transmitting the music through a phone connection.
Most of the wireless devices in the area where I tired it ran at a different band, so I can't blame interference. It seems like the device is just bad, plain and simple. There's nothing good I could say about the little details on the side either: There are no LEDs or anything, so you can't tell whether the sender is turned off or if it just sucks. The units themselves are relatively small, if a bit ugly.
All in all, the power supply situation alone is beyond belief. This unit is supposed to be used inside buildings, where you typically don't have exposed 12V cables that you can hook your gadgets to. I could understand it if this unit was designed to be used in a car, but anything that sees its primary application inside buildings needs to come with proper 110V power supplies. But even if it did, the quality is absolutely unacceptable and makes it impossible to recommend this product.

Terk LF-20S Wavemaster Wireless 2.4 GHz A/V Distribution System Review

Average Reviews:

(More customer reviews)I bought this to transmit PBS Kids channel from my 2nd satellite receiver in the basement to my toddle's room on the 2nd floor. Great reception if I turned off my 2.4GHz wireless network router and did not talk on my 2.4GHz cordless phone. With the router on, I got a strobing horizontal line down the screen. With the cordless phone, pressing the Talk button to use the phone killed the signal. I returned the product to the store.
If you don't have other 2.4GHz devices it seems like it will work well for you.

Terk TECHNOLOGY LF10S HomeNetwork Remote Video System Review

Average Reviews:

(More customer reviews)I purchased this item after having tried the Terk LF30S wireless system, which my 2.4Ghz cordless phone interferred with. Aside from the problems my phone caused with the wireless system, I feel that the wirless LF30S Wavemaster 30 delivered a slightly better picture. That's not to say that this item doesn't (well, read on), but I feel that it is slightly less sharp.
I first hooked up the LF10S to my phone jacks as the instructions say. However, the picture was fuzzy and the sound had static in it. Although I consider the phone wiring in my home to be in good shape, I guessed that there was just too much of it running all over the house, thus degrading the signal from the LF10S. Not being one to give up, and also being one that is relatively handy, I decided to run a dedicated phone wire from my living room to the bedroom, where I wanted the receiver to be. Aprox. $15 (100 ft. of phone wire & two surface-mount jacks) and an hour later, I had my dedicated phone line installed and tried it out. Much better!! I heard absolutely no static, and the picture was very clear. Although I previously stated that the LF30S wireless picture was sharper, that is not to say that the LF10S picture is not clear. I think most people probably wouldn't even notice the difference.
If you don't use any wireless devices that use the 2.4Ghz frequency (cordless phones or wireless networking devices), I would recommend the wireless LF30S Wavemaster 30. If you can't go wireless, then I would recommend this product on the basis of its video and audio quality, but be prepared to be slightly disappointed with the results from using your regular phone jacks. If you have a basement with an "open" ceiling like me (or even a crawl space), running a dedicated phone line would be easy to do, and would make a huge difference, especially if you do have poor picture and sound from your regular phone jacks. Even if you can't get underneath your floor or behind walls, you could even run a phone wire along the baseboard to the other room.

RF Link AVS-5812 Wireless Audio/Video Sender (5.8 GHz) Review

Average Reviews:

(More customer reviews)This product would be great - if it worked.
I bought this product and it worked great... as advertised... I loved it. Audio, video, IR (remote) worked and were clear. One morning, about 45 days after I bought it, it just stopped working. Assuming the problem was environmental, I had the unit extensively tested by an A/V pro. It was clearly the unit. So I contacted the manufacturer and sent it back. I had high hopes that I just got a lemon, and the next unit would be fine.
The second unit failed within two days (different type of failures). Again I had it checked out, and had the setup and placement checked thoroughly - I mean, what are the odds that two units would fail? Once again, defective equipment, and once again I sent it back.
Third unit lasted a couple of weeks - then failed.
DO NOT BUY THIS PRODUCT. I have extensive A/V experience and love the idea of this product. Don't buy a product that will fail in a couple of days or months. Find another solution.

LEAPFROG LF30S Wavemaster 30 2.4 GHz A/V Distribution System with Remote Control Extender Review

Average Reviews:

(More customer reviews)First off, the actual item looks just like the one without the remote extender not the one pictured. I installed the Remote TV in my kitchen which is next to my living room. I can see the kitchen from the living room, but I can't see the Living Room TV from the kitchen, hence the extender.
Pros: Works pretty well, video and audio are in sync and with the right cables, you can still use your regular TV to watch the same show as what's on the remote TV. The picture quality is quite good, although i'm only using a 20" TV. The IR extender works pretty flawlessly in remote location. Once you realize the antennas are directional and you aim them at each other it works great.
Cons: If you walk through the directional antenna signal, picture drops out, which is why the manual says to mount them as high as possible to avoid interruption. In my situation, I can see the IR repeater from my living room and thus when I try to change channels by aiming at the TV, it doesn't work because it gets my signal, then it gets the repeated signal and it must distort both the signals. Also, I've noticed that on one of the four channels, my Internet Wireless g network is completely undetectable if I'm too close to the repeaters. My solution was to turn off the repeaters when I'm not using them to save power and let my remotes and wireless network work.
Overall: the product has some flaws in my specific application, but over the long run, I think it will prove it's convenience as a worthwhile investment.

RF Link AVS-5813 5.8Ghz A/V Wireless Receiver Review

Average Reviews:

(More customer reviews)I bought one of these units in March 2006 in response to my wife constantly changing room arrangements, and subsequently requiring that the TV work in an area that didn't have easy cable access. I looked at several units from other manufacturers, and actually bought one to try from Best Buy, which was a Leapfrog, I think. Testing that unit convinced me that the concept was sound, and I would have kept that unit except that it operated on 2.4 GHz, which caused interference every time the microwave was in use, or the telephone rang. My computer is hard wired into a network as I don't want to deal with the increased security requirements of wireless, and my phones work fine on 2.4 GHz, so I was looking for a solution, but with 5.8GHz.
I called RF-Link tech support, got all of my questions answered and placed the order through Amazon.
Product worked flawlessly for about six months and then crapped out. By crapping out, I mean that when unit was in an enclosed space where there was exessive heat buildup, the unit would stop working after about 10 minutes.
I contacted RF-Link tech support, and they promptly sent out a replacement unit, explaining that the motherboard had been completely redesigned, and therefore they sent me new units as well as new power supplies. The replacement units have worked flawlessly.
Although I was upset at having to go through the return/RMA process and the delay in using the product until thr replacement was received, everything is fine now. I would recommend this product to anyone who doesn't want the expense of paying to install cable outlets everywhere.
And for those who are concerned about 5.8 GHz interference, with phones, 6.0GHz phones are already available, so no future compatability issues there either.
