Review on Innens Wireless HDMI Transmitter and Receiver Kits - Advanced Wireless Presentation Dongle Adapter for Laptop, PC, Smartphone - 4K @30Hz Streaming Video/Audio to HDTV/Projector by Brian Inman

I installed a video surveillance system that sends video to a monitor via an HDMI cable. Unfortunately, the camera's NVR (video recorder) was in a different room, away from the monitor. It would be very difficult (invisible) to run a 75ft HDMI cable through the walls and loft. I bought this wireless HDMI kit and plugged it into the HDMI ports of the dash cam and monitor and the video from the camera magically appeared in the next room. I thought the chances of it working were very slim, but to my great surprise, it worked and it was a simple plug and play setup. Wow, am I ever happy! One of my best purchases.
