I tried it on an iPad and was able to import. I'm sure it will be updated soon- There is a very slight lag since there is a .06 latency but not too bad. I might not use it for situations where a focus puller it required. Other than that I've used it without issue in live events.- Only way to transmit a 4K feed is through hdmi which i use anyway. SDI port can only do 1080Overall, this is another great product from Hollyland that I recommend if you're looking for a reliable transmission system for live events, small productions and situations that you need 4K. My favorite feature is being able to transmit to multiple devices fit example to the DP, camera operator, on a camera mounted on a gimbal etc. Now I will probably pick up the Mars M1 monitor that doubles as a transmitter!

I have many Hollyland products and really like what the company is putting out there. I already had a set of Tx/Rx but wanted to add just a transmitter to pair with my Mars M1 monitor (my favorite Hollyland product), and also for quick phone/tablet monitoring on smaller jobs.The build quality is wonderful, it is affordable, and the company really stands behind their products. Highly recommended!

the unit was seamless in pairing process size and simplicity. The quality was pretty good and almost on par with a teradek. Happy with the form factor and simplicity of this unit and do highly recommend it for wireless cams in a livestream stage setting as ours worked with led walls lighting and a very crowded rf environment ( about 10 wireless mics and 20 bodypacks) .

I have had great success with Hollyland units. This is my third model and they just get better.I think that the range depends on your environment. Whether or not there's a ton of other wifi / RF devices or not will ultimately be the biggest factor. Obviously test ahead of time if the environment is tough.Otherwise, everything works great and as advertised. The app is great too, very good option for a director's view.
I have been using the Mars 4K quite often primarily for the app capability. By having this daisy-chained off my AC monitor I can now have our Gaffer, Director, Art, and so on hook into the app and not give out a ton of monitors. On top of this, the form factor has been great for rigging!I use it often and have people rent it, so I grabbed another one so I can be prepared. I genuinely love what Hollyland is doing with their gear.
Bought this specifically to work with my new RS3 Pro gimbal. It's very solid and has not failed yet. Works great with Hollyland app to use with smartphone. The RavenEye on the gimbal is just not as robust as this unit. There is a bit of latency and if you are doing critical focus-pulling, this might not get it done. But for excellent reliable high quality transmission at a reasonable cost, this perfect.
This is just awesome. I chose the 4K version and was a bit skeptical, however, the Mars 4K didn't disappoint. Worked right out of the box.I could preview it on a monitor, I tried the TV and iPad too. Everything worked well together. I did not test the range, but it works well in my studio and on the TV in the next room in 4K.Just a heads up, if you have an older TV is 1080p, it might not recognise the 4K signal and display 'no signal'. When I switched to 1080p recodring on camera, it worked on that screen too. Just FYI.
I already have the wireless M1 monitors and wanted this transmitter because I know that now I can mount this to my camera and have it transmit the camera's feed to both my Mars M1 monitors. They work flawlessly and now I don't need to have my monitor on my camera to get a wireless feed going. If you are already in the hollyland ecosystem then this is a great addition to it
Solid, good build quality. Linking them is super easy and stable. Having the HollyLive app is nice so you can have an iPad as a set monitor or what Not. One downside is that if you have HDMI in to the transmitter, you have to have an HDMI out of the receiver. It would be nice to have the ability to have HDMI into the transmitter and SDI out of the receiver. Really that's the only feature it's missing. Over I would recommend for a cheaper yet still solid wireless transmitter.

So whether you're filming in a crowded caf or a wild forest, your signal stays strong and steady.The big L word latency. The MARS 400 4K is on top of its game here. That latency is so low, it's practically in hiding. Your video and audio stay locked in perfect sync, no awkward delays to mess up your mood.I think as soon as you get a video transmission system you discover a hole world and step up you job/quality level. And when you are there Hollyland has one of the best in the field with their gear.
