I do live streaming and video production and was very thankful to be able to use it to live stream last week's wedding event. Normally, my live streams are in line of sight of all the wireless transmitters and receivers, but for last weekend's event we had to move from outdoors to indoors. As a result, there was no room indoors to install my system, and we had to install the video switcher from outside with the glass door closed, only to find that none of my other transmitters could pick up the video signal. I plugged in my new 4k Mars and it worked perfectly with no signal loss. I have used various wireless video systems and have found this one to be very quick to sync and pair. It channels very well and has automatic channel scanning. And the 4k feature is great. The wireless signal and new antenna are very stable at this price point compared to other video wireless companies.
