  • Transmit
Size: 1 TX + 1 RX
One thing I did not expecting is that some older camera can transmit video on my new updated camera. I don't know why. I tried to set up to 1080p but it does not work. Works fine with 4k.

  • LIVESTREAM SAVER
Size: 1 TX + 1 RX
I do Livestreaming and video production, brought this unit last week and I'm so thankful enough to have this in my hand for live stream wedding event that happen last week. Usually, my livestream is in line of sight for all my wireless transmitter and receiver, but last weekend we have to move from outdoor and indoor for the event. So, there were no room indoor to setup my system, we had to video switcher from outside close glass door, found out all my other transmitter couldn't get the video signal. I plug in the new 4k mars and it work perfectly fine without signal loss. from there I knew this was a keeper for my live video switcher. after get thing working. I have to move all my receiver to inside of the reception room for other camera to work. I use all kind of wireless video system and found this model is very fast when sync and pairing. The channel is very good it has the auto scan channel. I gave it 5 star Because it has a lot of improvement and quality to this model, 4k function for great cause I can now do cropping in my vmix switching during livestreaming. Wireless Signal and with New antenna are very stable for this price range compare to other video wireless company. ... show more

  • Awesome range and latency
Size: 1 TX + 1 RX
4K transmission at very low latency and stable signal. Works quite well for both our camcorder and DSLR cameras at our church. Looks good too. Being able to view on multiple phones/ipad is nice. Would strongly recommend.

  • R5 and R5c only work in certain modes
Size: 1 TX + 1 RX
Works great for adding a wireless 4k camera to live streams. Only down side is switching to slow mo or any other mode on R5 or R5c results in not supported screen and no video output. Even with slow & fast 120/24fps on R5c it will not output video. Using HDMI direct to my capture cards it will just fine and let me record slow mo while showing live normal speed video to viewers. That's disappointing as I was expecting similar to direct connection with HDMI out. Not a deal breaker but if you film in anything other than 24/30fps 4k it will not output anything, tried all settings on both R5 and R5c. Lag is minimal just offset your audio for scenes in OBS so they match up for live streaming. ... show more

  • Great value kit!
Size: 1 TX + 1 RX
I so far love this set. The ability to turn it on and it just syncs up in 20 seconds, never had an issue over the course of a week. The added ability to log onto the app and also use your phone as another monitor is great. The latency at least within a 30ft or less range is perfectly fine and I was able to pull focus with the monitor. The only issue I have noticed is that in flat colors in low light situations the image does break apart a little, likely due to the compression. But if this is a review stream to check focus, framing etc, I thought it was acceptable. And I really only noticed it while testing prior to the shoot, once onset I never noticed this, so in reality, it may be rare. It would be nice if the SDI input would also mirror out to the HDMI on the Transmitter, a minor grip given these are less than half the cost of something like the Teradek Bolt 500. ... show more

  • Great image quality!
Size: 1 TX + 1 RX
The media could not be loaded. I've been looking for a wireless system for a LONG time, and these finally came out and seemed nearly perfect. The latency is pretty low, the image quality is PHENOMENAL and the form factor is both compact and incredibly robust. These are going to last for a LONG time, and I just love having a crystal clear signal. They also mount to my rig VERY nicely. Now I might get the M1 Monitor to go with this since it connects natively! I'm loving this system! ... show more
