Hollyland Mars 400S PRO [Official] Wireless Single Receiver, Support SDI & HDMI Output at The Same Time, Compatible with Hollyland Mars M1 Wireless Video Monitor (Single Receiver)

I've enjoyed using this wireless system so far - with minor user experiences they could improve in the future. The USB-C power port in the back could be better by not being so deep into unit; some USB-C cables don't fit properly/easily comes out. It seems to hold a signal well, and finds it again fairly quick (10 seconds) if it drops. Outputting to IOS devices is a GREAT feature. For the value, this one is a keeper. Although I'd recommend using SDI rather than HDMI because it the latency does get pretty noticeable (especially for focus pullers).

A few months in can’t even get it to recognize a video source is plugged into the transmitter 👎Expensive tiny bricks

For the price of the product it is amazing. It gets amazing reception… well over 100’ through walls. Their customer service is spot on. I sent them an email telling them my pros and cons of the device, and they were receptive. A lot of the cons they say they fixed in the 4k transmitter, but I haven’t worked with that one yet. However, I did use the one before the 400s and it was awful. I could stand right next to the transmitter with the receiver and it’d cut out. Reception is quality on the 400sMy main pros:-price-the build is pretty durable-love that people can tap in with the app while also using the receiver-love that I can change/select channelsCons:-ports/cable inputs are a little all over the place. Makes for weird builds sometimes-they really need a 2/3 pin lemo power option-fan is loud-image can become blocky and hard to pull focus from if the device gets hot (think like direct sunlight middle of desert summer hot)
