Wireless HDMI Extender Kit, Supports 1080P Full HD 200m (656ft) Wireless HDMI Transmitter and Receiver with HDMI Loop-Out and IR Remote Control for DSLR Camera Projector Laptop Church Home Office

I used this to send HD (1080p) video and audio from a cable TV box located in our master bath to a second TV in the master bedroom. This way we removed the requirement for a second cable box and CATV wiring in the master bedroom. The unit replaced an "ActionTec" (now "ScreenBeam") wireless TV extender purchased in the mid-20-teens. While I'm sure the ScreenBeam device has improved since then, the ActionTec device suffered from severe image and voice lag (1-2 seconds), slow activation (over 30 seconds), and a "wireless remote" feature which never worked. In contrast, the BovBox device has virtually no image/sound lag, comes up immediately, and the wireless remote function works well. (Clarification: You don't get a wireless remote control with this. Instead, the wireless remote "function" is an IR receiver which lives at the remote TV, and an IR transmitter which lives at the host TV. When you press the button on your TV remote, the IR receiver sees the signal and sends it to the IR device at the host cable box, which "repeats" the signal for the cable box, thus changing the channel.) In this installation, the HDMI output of the CATV box is connected to the BovBox HDMI input, and the HDMI output of the BovBox is routed to the input of the TV. (I call this the "Host" TV.) There is also a small "wall wart" power supply which is plugged into a wall socket and provides DC input to the BovBox. There are no provisions for using a USB connector on the TV for power -- that would be nice, but I suspect the current draw of the BovBox would be too high for the USB port. The BovBox receiver is placed behind the master bedroom (or remote) TV (which is in a cabinet) and is out of sight. It has only a wall wart power supply and an HDMI output, which feeds the HDMI input on the TV. Both the transmitter and receiver are "on" all the time, so there is no power-up or syncing time required. The transmitter and receiver are "pre-paired" from the factory, so no need to go through convoluted pairing processes. The transmitter power is more than enough to cover the distance from the bath TV to the bedroom TV -- probably 20 feet, including one tiled wall and the furniture cabinet holding the bedroom TV. There are two shortfalls. First, the tiny symbology and pictures with the installation guide make it very hard to determine which is the IR receiver and which is the IR transmitter. So I would up doing a "best guess" and I got it right .. but it was a guess and I could have gotten it wrong. Not sure how the IR devices would react if they were plugged into the wrong device ... I hope they wouldn't be damaged. Also: the adhesive pads holding the IR devices are very strong -- so strong, in fact, that you really can't move them once put in place. They just rip instead. Do your best to get them in the right spot the first time. Second shortfall -- and it's not the fault of the BovBox but of the TV manufacturer -- If you have a "smart" TV with built-in streaming, etc., you can't send the streamed video to the remote TV. There's no way to get the HDMI video *out* of the TV to get to the BovBox. If you want to stream on the remote TV, you'll need it to be a Smart TV or have an AppleTV, Roku, Fire device, etc. Final comment: I chose this device specifically because the "host" device has both HDMI input (from the cable box) AND HDMI output (to the host TV). There are other versions which have an HDMI input but no HDMI output -- it remotes the image only, and is more appropriate for conference rooms or computer presentations. You'll need both input and output for a local TV as well as a remote. All in all a very good device, works as advertised (and better than I expected). A little pricey but worth the money ... glad I bought it.

I recently moved my elderly parents in with us. Our primary Tv was in the family Rec room downstairs. My parents were unable to do stairs. I have multiple tv s , but only one cable feed. This product worked beautifully!!! So easy to set up. I followed the instructional video, and was watching tv in 10 minutes remotely. The distance between the two units was about 50 ft, and one floor up/down. Super clear picture, no delay or distortion. Would def recommend this product. We can now watch Netflix or Prime on one set downstairs, and my folks can watch ( and change channels) as they wish upstairs. No issues , and an early delivery topped it off. You do have to have HDMI cables though. Amazon had those for $16 for two.

送受信の安定性は良好です。送受信が上手くない時は一度、電源のリセットで復帰します。慌てずにセッティングをするのがコツです。レイテンシには注意が必要です。説明書きにある数値は信用しない方が良いです。実測すると2フレーム＝1/15秒の遅れがあります。仕込み時間に余裕があるなら、有線でSDIケーブルを引き回す方が良いかもしれません。映像はキレイです。ご参考ください

Muy prácticos!

I had a similar product from POFAN https://www.amazon.ca/gp/product/B09FPHWNHY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 which kind of worked but with stutters, so I got this one. Works perfect, no stutters, lags, etc. I recommend it.
