Wireless HDMI Transmitter and Receiver, Wireless HDMI Extender Kit with Loop-Out, IR Support, 2.4/5.8GHz 1080P Full HD 820ft/250M, for DSLR Camera Projector Laptop Church Home Office

I love these systems. They come pre paired, can be powered off of the USB on the back of most TVs or any power supply. The signal goes through a metal case. I use them for a photobooth system as well as karaoke services.

These are basically a transmitter receiver pair that use a WiFi technique to send and receive an HDMI signal (along with IR information). My application has them working through two walls though at fairly close range of about 30 feet. The signal is sound and shows no artifacts though there is a slight latency of about half a second which would complicate their use for something like gaming. My one complaint is that the mounting sockets (threaded brass) are very shallow and only allow for slight threading of an M6 bolt to secure the devices. Short bolts are required and not many threads hold the device on the mount. They draw power through 5V adapters which connect with a USB-C connector. The provided cables are much too short and I had to get longer cables to get from my outlet to the devices in the locations they were placed. Another complaint is that although a single transmitter is available with multiple receivers, additional transmitters are not available individually. In my case, we want to hit the receiver from multiple locations at different times (only one transmitter on at a time) but you have to buy the set to get another transmitter.Appearing to work fine so far, these are small, reasonably priced HDMI (1080) wireless solutions.

I got this to replace competitive set that worked great, but died after 3 months.Product looks good and setup is simple. Everything started perfectly. HDMI Receiver connected to projector, HDMI Transmitter connected to AV receiver. Xbox and set top box connected to AV receiver. All devices are 1080P.Everything worked great, for about three minutes, then the connection stops. Change from XBox to Set top box, it works again, for a few minutes, then stops. Change back, ok again for a few minutes, then nothing.It appears to stop after a few minutes if I am streaming a movie from Netflix, Amazon Prime, etc. on the XBox or if I am watching anything on the set top box. Essentially anything that has copy protection.I am wondering if this set supports HDCP. If not, it is useless for any home theater application.1 Star for now. We shall see if I get any response from support or this is going back.UPDATE 7/21/2022: Support was very responsive and confirmed that the device does support HDCP 1.4. Unfortunately the AV receiver I have sends HDCP 2.2 protected data. This is why it cuts out after a few minutes. If I connect the XBOX or settop box directly to the transmitter, it works fine, but then there is no audio to the AV receiver or ability to switch inputs. That's why I have an AV receiver. Their support recommended that I disable HDCP, but that disables the ability to send protected content. In a home theater, essentially everything is HDCP copy protected. A Theater without the ability to watch TV from a settop box or stream a movie from anything is essentially useless. I really wanted this to work as the quality looks good, but not supporting an 8 year old HDCP 2.2 spec is a show stopper. Returning this.

The application...need to send my family room Direct TV satellite receivers HDMI output to a TV on the opposite side of my house in my master bedroom, approximately 60 feet away, going indirectly through 3 walls. By doing this, I save on the extra $10 charge per month for an additional DTV receiver in addition to still being able to have the master TV connected to my awesome Televiz $200 out door antenna for over the air reception. Tried the TPUFO brand @ $129 and the Dbilida brand @ $79. Both failed miserably within 35 feet of pre-final installation line of sight testing. Bought the Weeryyi TX & RX with an extra RX for an additional TV during the recent Jult 17 Prime days @ $205.44, tax included. Couldn't be happier with the signal stability, quality and set-up's performance...Highly recommended!UPDATE...I forgot about mentioning one issue...Although the TX & RX are communicating what appears to be effectively, the L.E.D.s on the side of each continually flash red as opposed to being solid green. When I change DTV chanels from the master bedroom, there is a slight delay showing a black screen with a diagram of possible connected devices and numerical wifi, etc values, then the changed channel picture appears..basically a 3 second latency. Any other users have this issue and /or what is the fix for both the flashing red LEDs and the latency display? Thanx!

These things work flawlessly! Been using them for karaoke when I have channeling places to place my TV and don't want to string an HDMI cable across the floor. ZERO lag! Absolutely - highly recommended.Read the instructions when setting up and call tech support if you have an issue or go to Youtube for instructions. If it's not working right, it's probably user error. Took me a couple tries to get it right but it works waaaay beyond my expectations.
