Hollyland Mars 4K Wireless Transmitter Receiver 5G SDI HDMI Video Transmission System, 4Kp30/1080p60, Support 23.98/29.97/59.94 FPS SDI Out, 450FT Los Range 66ms Latency, 4 App Monitoring (1TX+1RX)

Worked perfectly right out of the box. A huge improvement on the previous mars products, the range is much better. The fans are quiet and have caused no issues despite what some others have said.

Performance is truly excellent. Just mount, turn on and go.

We needed to replace our previous Hollyland transmitter and thought we would give this a try. The picture quality and stability is amazing and the new stumpy style antennae’s made us feel that the didn’t have to handle it with kid gloves in the normal day to day shooting. Most of our shooting is run and gun and we can be in several locations in one day, so the conservative battery consumption means that one set of Sony NP70 batteries easily lasts the whole day. We had a few delivery issues but the one thing we can attest to is that the Hollyland customer service is best I have experienced from a technology company - they get back to when they say they will and are very solution orientated which is an important aspect of product purchase for us as a small production unit.We have already ordered two additional pairs to upgrade our kit and the whole team love them. Can’t wait to see what they bring out next.

This works well with 4K, but I can't get it to work with ProRes RAW footage (from my Nikon Z6 to a Ninja V.I did talk to support, and as I was going to send it back, I was a little underwhelmed with their response of 'it should work'.I ended up keeping it, as the Nikon is not my main camera and I had a use just to beam to a 4K screen.

It delivers what it says, although I haven't had the opportunity to test it for long distance yet. It's worth the price.

These really do offer great value for money. They boot up and sync to the transmitter with ease and the picture quality is excellent. There is noticeable latency, especially when using hdmi in and out, but what do you expect. There’s a lot of processing going on and that takes a small amount of time. I’m using it for a directors monitor so the slight delay isn’t really an issue. If you listen to the embedded audio then at least the lip sync remains intact too.Overall great value and I’d totally recommend.

Having come from Teradek Bolt series, I can say that for the price these work as good if not better than the early 500/600 series. Maybe not ideal for AC pulling due to tiny 5ms latency, but the fact that you can stream to Rx and then ALSO everyone else iPhones/androids (4-5 devices I think?) means these are bang for buck better than bolt.

The media could not be loaded. Having owned a previous version of this transmitter, I was excited to benefit from the upgrades on this version including the 4K capability.The new design is quite nice and the repositioned display on the side of the device is a lot more convenient for me at least..The set up time is minimal, the Rx and Tx pairs seamlessly but if you did want to, you could switch to a more convenient channel.Build quality is decent with solid switches , buttons and ports.I'd definitely recommend
