Wireless HDMI Hollyland Mars 300 Pro and 400S COMPARED

Photo Moment - October 30, 2020

Wireless HDMI is a beautiful thing, and following up on the success of the Hollyland Mars 300, the company released the 300 Pro and the 400S, each with its unique advantages. In this recorded-live-test, I compared the 300, 300 Pro and 400S in features, a live range test, and latency. The results may surprise you!

pleas joseph can you demonstrate how to take a color photo with a CMY filter in a B&W camera ( technicolor method ) just a few people do it but with lighting color gell or low res security B&W camera
I’m not doing a new video specifically on that but this one from a few years ago is pretty close https://youtu.be/2vgVtkZRYb0
@PhotoJoseph
I have seen that video, that why I ask you if you can make the 3srip experiment, hope one day ❤️🙏
what is the delay in the image if I connect to ATEM mini PRO and other inputs are connected to cameras via HDMI?
HDMI into the ATEM directly is no additional lag than what’s already coming from the camera.
Fantastic review and compartion!! Thank you for sharing that!!!
Glad you liked it!
Hmm... Looking to pick up 3 mars 400S or 400S Pro (for live streaming to a multicam setup). Do you think three of these would interfere with each other (causing unexpected, intermittent signal loss)?
If they are close to each other, they can, as I experienced in this video. But I also had them literally inches apart. I use three in my studio now, all in various places, with no problems.
@PhotoJoseph Awesome... And you use them for production? (Not just monitoring?) I'm torn between the 400S and the 400S Pro. Even though I wouldn't need direct streaming on a regular basis... I can see how it might come in very handy, if I wanted to go live with one camera and didn't want to haul my whole rig.

Thanks for the reply. Cheers!
Using all of them together is not so fair... Even in another channel there is some wireless noise. It is better to make a test with each one of them seperately in the same channel. Also no one has ever showed the pull stream function! If it is stable / better / less delay etc
this comparative review made med decide to choose300 pro.great job
Thank you!
Thanks for the video Joseph! Just pulled the trigger on the 300 Pro. It'll end up on my go.dingo rover transmitting the video from a GH5/Ronin S to an operator with an S-Bus controller.
Perfect! That's a great use for it.
Thanks for the review!!!! Quick question. Can I record 4k on my a7siii while monitoring 1080p on the mars 300 pro?

Thanks
I would like to know this too!
Can I have 2 Transmitters going to 1 Receiver?
Do you know if you can use a 300 RX as a second receiver to a 400s TX?
Thanks Joseph! Have you made a how to video for using something like the sennheiser 500 series wireless mic with an iPhone?
To reconnect to the app; I don’t have an answer for that, sorry. Given how much more quickly the 300Pro connected though I’d assume it to be similar for wifi
How long it reconnect to app if signal is lost, or you quit from app? Is there any difference with 300pro and 400s? Thanx for answer
Thank you for the review, i will proceed with 300 PRO.

Just one more query, can multiple (let's say 2x transmitter feed HDMI signal into 1x RX module?)
I bought the 300 PRO TX and for interviews it's completely unusable with the app, see it for yourself at 14:50. It's NOT lip sync.More than a second delay, sometimes even more.
The WiFi latency is definitely slower than the hardware connection, yes. If you need the near realtime performance, use the Tx and Rx, not just the Tx and a wifi device.
I’m not talking about the latency, that’s just fine. I’m talking about the lip sync. Audio is much too late, but when you record into your mobile by the app it’s perfect in sync.
Oh I see. How about using the receicer?
I bought this unit specially for iPhone/iPad.
Love the review. I wish you would review the Hollyland cosmo line
thanks mate ..
👍🏻
Very useful - so well put together. Just had the 300pro enhanced delivered - so this confirmed my decision to opt for these. Thanks again.
Awesome!
Which one has the highest range in meters in open area like ground?
That info is in the slides
Mars 400S Scene Mode review, please 🥺🙏🏽
Can you use a handful of these with an ATEM Mini Pro for the ultimate wireless studio setup? Guess I should watch the show!
You can! I have done this with two wireless rigs before. The interference I talk about in here is because the transmitters were side by side, but having the receivers in close proximity has not been a problem for me.
Plenty of good info to help with my question, thanks Joseph!
great!
