Hollyland Mars 4K Wireless Video Transmitter 5G SDI HDMI Transmitter, 450FT Los Range 66ms Latency, 4 App Monitoring 3 Scene Modes, Compatible with Mars M1 Wireless Monitor (Single Transmitter- 1 Pcs)

These work very well and we have bought multiple of them for our church video displays

Great product worked perfectly fine

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.

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!

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.

I used this often and highly recommend them to filmmakers.

El producto es perfecto y llegó rápido a Perú. Funciona bien.

Haven't tested it extensively, but we fed in 4k footage from a Sony RX0 II and the RX to a 4k TV and it worked like a charm! Turned out exactly like how it looked directly plugged in! The range was hard to test because we are in a trailer, but we walked with the camera outside of the trailer for about 50 feet and before it started having connection issues. (mind you, this is through the trailer walls, through another trailer, and then by a bunch of Construction excavators and loaders. There is about a quarter to a half second delay, but this is fantastic for our purposes! I also don't think this has an internal battery, but we ran it off of a mobile power bank with USB C PD and had 0 issues! Overall, a fantastic product that works super easily!
