Portta PET50EP HDMI Extender Adapter Over 1 Single Cat5e/6 1080p Extension Cable Support 50M

I purchased this unit in July of 2010 to power a projector in my A/V room. I do not use it to carry audio at all, just video. For the most part, the unit worked well and consistently projected direct and upscaled 1080p from my Pioneer VSX-1020 reciever (notice I used past tense here..read to the end to see why). It was connected to an Optoma HD20 projector with about 50 feet of factory terminated CAT5e cable bettween the transmission and reciever side of the extenders and a 6 foot HDMI cable on each end. The Optoma also has a passive VGA via cat5e connection for computer use. Signals passing through and being upscaled by the Pioneer include an HD Tivo, a Sony Blu-ray player, a Wii, a PS3 and occasional iPod video. When first powering the system on or any time the Pioneer reciever is switching inputs, the Optoma drops or hunts for a few seconds, which I think is normal when the input signal drops. It hunts around, identifies HDMI 1 and finally syncs up with the reciever after maybe 5-10 seconds. Once in sync, all forms of video come across crisp and clear including blu-ray...all of this is perhaps more a function of the reciever than anything else, but I'm thinking a small part of the delay is due to the cat5 extenders.The only serious anomoly I see is probably more related to the unshielded CAT5 cable than these units. It might occur even if I used a 2-CAT5 set-up. I have a treadmill in my A/V room so I can run while watching TV or a movie. The interference from the treadmill motor, on a separate circuit, causes the video signal to drop occasionally whenever there is a heaavy load on the motor. I have considered adding shielding to the motor but fortunately, I don't use the treadmill all that often. OK, here's the bonus you get for reading this far. Last night my 13 year old daughter had a sleepover so she and her friends displaced me from "my" A/V room until this morning. Today when I tried to power up the system, I got no video. After considerable troubleshooting, I discovered that one of her friends had flipped the now never used extra wall power switch off and on a few times trying to get the lights to work (There is a lutron remote dimmer switch right next to it that apparently is not intuitive for a typical 13 year old who knows how to do everything.) The only thing the switch controls is the projector and the reciever end of the set I'm reviewing so we can turn them off when travelling. Well..., although the projector has a safety relay, the rapid switching of the power must have caused a surge in the cat5 reciever power supply, blowing out the reciever end of this pair and, oddly, the power supply on the transmitter side. If this failure surprises you, keep in mind that power conditioning is a huge industry these days because most electronics are so cheaply made that even an unstable AC sine wave can damage them.So, the unit works reasonably well with good cables, good equipment and no EM interference nearby...oh, and no 13 year-olds who don't understand that flipping a power switch off and on repeatedly can damage electronics.So, the ultimate question: Am I going to buy another one of these units? I think so. The run between the reciever has 1 factory terminated and 3 unterminated cat-5 runs. Although the drop-out because of treadmill interference is annoying, I do not want to have to terminate and balance the other cat-5 cables to use a dual cable set-up. Frankly, I want my A/V system back right away and this set-up, though not perfect, is good enough.I hope this review was helpful for you.

The main reason I bought this item was to reduce the number of boxes that I lease from my satellite company.The good news is that they actually work as promised and overall I am very pleased. It is a basic plug & play.Now the bad news: Of the three units that I ordered, one was defective. I had to return to Amazon and getting the refund was a bit of lengthy process but successful. I ordered two more (one to replace the defective unit) so I now have four of these extenders. The other bad news is that they are made in China. The final bad news - you of course need to have Cat5 or 6 wires to your cable or satellite box. One cat5 will carry the HDMI signal from the extender's sender unit to the extender's receiver unit where your TV is located. You will need to buy a large box of Cat5e and learn how to attach RJ45 jacks to each end. (This takes some practice and a couple of special tools.) In my house I am fortunate to have Cat5e installed otherwise you will have to find a way to run the Cat5e or Cat6. This can be a challenge after your house is built. Then you need another Cat5e to send the IR signal from your TV location to your cable or satellite box in order to change channels and use other functions. (There are also wireless methods to transmit IR signals.) It would have been an exceptional bonus if these Extenders also had IR transmission integrated in the box. I believe that more expensive extender units do have IR as part of the unit.In addition you will need an HDMI splitter. I purchased the: ViewHD 4 Port HDMI 1x4 3D Powered Splitter Ver 1.3 Certified for Full HD 1080P (One Input to Four Outputs)from Amazon. This splitter is based at my satellite box in my home run room. It successfully allows me to split the original HDMI signal to the four extender sender units. You will of course need to order a bunch of short HDMI cables and Cat5e patch cables to connect the sender and receiver units to the HDMI splitter and the TV on the other end. I am counting at least 9 HDMI 3 foot or longer cables to set up this system. (Ordered from Amazon at a very reasonable cost) So now I can watch TV in my office, bedroom, dinning room, and exercise room from one DVR satellite box.The system will pay for itself in about 2 years if nothing breaks and the technology does not change. Two BTWs: You realize that since this is all off of one DVR box that you can only watch one program at a time on all four TVs. So all four of my TVs can be running at the same time but all having the same program. The second by the way involves an electrical interference problem (described by another reviewer) when we run our treadmill in our exercise area. This is definitely related to the extender. It was cured by adding a battery back up/surge protector device which apparently filters out the electrical noise or interference. My longest run of Cat5e is about 80 feet, and sound and video are excellent. Now over 6 weeks of use and still working well.Sorry about the length of this review.

Producto más barato que otros pero como dicen, lo barato sale caro. Duro funcionando solo 3 meses.No se los recomiendo

Recomendable .. buena calidad.

Did not work, wish I had saved the boxes to send back. Bought a startech which worked instantly.
