Yo Adam I don't know why you just don't make a TV show about you exploring stuff and it only Stars you kind of like MythBusters but more to it like I really loved your VR thing where you explore creative jobs
i love my 400S (non pro). I use it almost every week at church for my hand held camera. i've gone through 4 18 inch thick reinforced concrete tilt (prestressed concrete) walls with the receiver in the lighting grid of the main sanctuary and i can walk anywhere around the church pretty much without any latency or dropouts... holly land is awesome. oh and i'm using SDI from a canon XA25
It's almost certain the lag will be present on the SDI side too, both use 3 channel color so they're probably sharing most of the same circuitry right to the point of I/O.
Coming soon to a developer den near you "laser radio waves". Recently "discovered" (read perfected), once a few tech hungry companies get their mitts on this, it will spread like ... well, we all know what. Anyways, it's very fast, and works really well, true, in lab conditions. But the technology itself is old as balls and such, there's plenty of pre-existing technological blocks for devs and engineers to use and speed up the process. We're not reinventing the wheel here, we're making sure it's not using a wood bearing. I've "some" experience with this, myself and a few friends played, some years ago with laser (actual laser diode and receiver) based wi-fi. And outside the obvious limitations regarding movement (which for something like this HDMI transmitter-receiver would be a problem) it was and is, the fastest wireless experience i've had in my life. The lead in that project is still using the hacked up NetGear router, and feels no need to move to a modern solution. Speeds of the LAN in wireless format...except for super dusty days, that, was never figured out back then.
I've found the delay to be very low on the HDMI side. Barely noticeable. We feed audio via wired microphones and video via a the 400S and no-one has ever noticed any lip sync issues.
We've been using the 400s (not pro) to add some flexibility for one camera in our church livestreaming for a couple of months now. They were even cheaper and as far as I can see the main difference is they have rotated the form factor which makes more sense for mounting on cameras. They are great little things and work comfortably at 250 plus feet in a medieval church full of stone pillars, the couple of weddings we streamed due to covid restrictions on numbers were particularly grateful that their remote friends and family could get close in on all the action.
I do this with production at a church... the ATEM TV studio HD is in the sanctuary connected to the various items audio console, computers, cameras (I even splurged for a teradek) and i pulled 2 SDI cables back to video village one is a multiview, which goes on a big tv screen, and the other goes into a blackmagic decklink mini in an old dell computer. works GREAT and the ATEM software has mixing functionality if i want to mix in the camera audio to get crowd noises.
I wish they would put a 1/4-20 mount on different surfaces of the device so you could attach it low profile. I'm very interested in this for live wireless streaming, and it looks like it works well. It just looks very cumbersome.
That is a good off the shelf product. I ran a HDMI cable with a powered repeater in my house to go down the hallway, down the stairs, and then back up the wall to my projector, It is something like 125 ft. And network and audio cables too. If these have no battery, can you turn the power on to them via USB-c and have them automatically start without pushing any buttons? How about the audio, do they transmit that too? Is the USB-c only for power or can you hook in a hub and wirelessly send a (wireless)keyboard and mouse signal back to the receiver if it's USB wire is connected to a computer? In your setup, can you have more than one pair of these if there are multiple cameras and multiple monitors? I don't know if there is remote desktop software that sends 4K at 60Hz, or if WiFi networks can handle that much data streaming, but that was my concept of how to set it up with an entire Apple Mini computer connected to the 4K projector, but it wouldn't be as simple as turning it on and having it all ready to go.
It says on the package that you can connect the RX through a USB-C Standard RJ45 cable and you should be able to use the stream through your PC/MAC. i have tried this with NO luck, can you help????
Just a quick ques is it possible to record the video in the camera's (Mirrorless bodies like Z series, Sony Alphas and Canon R etc) memory card and simultaneously make it go online through Atem Mini at several social platforms? like 2-3 youtube channels, insta, fb etc? Would be grateful to know.
You Mention that the reciever doesn't transmit 4k, and using a Ninja V willl not be suitable. If you record out of the camera directly to the ninja in 4k, then change the output of the ninja to a 1090p and then transmit that to a monitor. Is that possible?
It's generally not a good idea to record anything coming out of a wireless link if you can avoid it. They use lossy compression to be able to fit the data in the limited bandwidth available, so it'll never be quite as good as the original signal.
@@volltesdalTV Ah ok I thought this was newer tech that avoided that. Bandwidth wise we're getting to the point where we should be able to stream prores, at least at HD.
@@fen4554 First, I should say that I was commenting on RF tech in general and not this device specifically. But for comparison, the links we use at work typically gives us around 20mbit with a 10MHz bandwidth. Not too bad, but not close to ProRes. We got the first of our links a few years ago now, though, so these and other new units would probably be able to get a higher bitrate. (I say probably because I don't know how this thing being on 5GHz public frequencies instead of licensed freqs affects bandwidth and bitrates.) But I would guess that by the time wireless links are able to transmit at bitrates comparable to ProRes and the like in HD, we might very well have moved on to "better" formats needing higher bitrates anyway.
I just bought three of these. Haven't Recieved them yet. One question... Are we able to go IN Hdmi and come out SDI? Or does the in /out method have to match?
Hello! I bought the Mars 400s pro kit with a second receiver and although it connects the signal it does not send video. Did it happen to someone? any solution? Thank you very much for the video!
its range is probably accurate, with an empty room, set up to not reflect signals, and isolated from outside interference. it may actually get the 400ft is such a testbed scenario.

I have no use for this, but I love the excitement from Joey telling about this :D
I can’t be the only one that thinks these look like some Metal Gear MacGuffin
Fascinating technology
Good to see you out there Joey!
I know there is lag with the HDMI but does the SDI have any lag? I've been looking at this system for a while now. Thanks for the review!
It's almost certain the lag will be present on the SDI side too, both use 3 channel color so they're probably sharing most of the same circuitry right to the point of I/O.
All of them will have some latency. Intel's WiGig stuff is fast enough for VR and under 10msec but has extremely limited range.

Also just speaking from experience owning a GH5 myself, the camera in the video has about a 0.3 second delay when outputting over HDMI.
That's so cool!
I love the videos about camera and film gear.
No idea what I would use it for but I love the look of it. Very Alien (film) style to it.

I think that equipment could soon go cheap(er) since it will be further developed for wireless VR

That t-shirt is super trippy
i have a question, how do you turn them on?

Would this work for say having a game console in the living room connected to a tv and then transmitting to a tv in the bedroom?
sounds like it would. its just HDMI in and HDMI out with extra steps
I don't know how much latency there is but it has to be noticeable
You’d need a long cable for your controller
@@illgottengains1314 most game consoles are wireless and the controllers can be charged using a wall plug
@@selymred I doubt they’d work that far away tho, also another console would be much less expensive
Can this transmit direct to a LED monitor with HDMI in without installing the Hollyland APP? either computer monitor or standard TV.
Are the antennas regular sma/rp-sma? Could you slap some cloverleaf or patch antennas on there for better reception?
Red is hot (output), Blue is cold
Hey Joey, have U seen the " 3d printed 10 k Camera arm by Alexandre Chappel ? This might be something for Adam ;)
For the of of me I do not know why they abandoned the 400S form factor.
Is interference from 5 ghz wifi a problem with these?
Thanks for showing! Thats quite a bit of lag. oO
How hackable is is?
How jamable is it?
Can someone do a middle man attack?
Can someone impregnate the signal with unwanted noise and /or imagery?
Just a quick ques is it possible to record the video in the camera's (Mirrorless bodies like Z series, Sony Alphas and Canon R etc) memory card and simultaneously make it go online through Atem Mini at several social platforms? like 2-3 youtube channels, insta, fb etc? Would be grateful to know.
The future!!!!!

Did you experience any dropouts at all while using it in the same room? Is this safe only to use as a monitor or could you actually master off of it?

Anyone know if this will work well to transmit videos from a laptop ?
Sorry quick question ? What if i have two cameras can it be possible to have two transmitter with one reciver or how does that work out?
I just bought three of these. Haven't Recieved them yet. One question... Are we able to go IN Hdmi and come out SDI? Or does the in /out method have to match?
Hey I have a project transmitting a video into outer space. Do you know how I would do that?
Hey great video! Can you send me a link to where I can buy a battery for the transmitter?
Hello! I bought the Mars 400s pro kit with a second receiver and although it connects the signal it does not send video. Did it happen to someone? any solution? Thank you very much for the video!
Can you add luts in their app if you shoot in log space?
what stand did you attach that monitor?
Can this be used from a game console to a tv? And could it be used with multiple systems? In the sence of three consoles to one hdmi port on the tv...
Sooooo where is the actual test
Test the pull stream (throught lan) function, no one has done it!
Surprised DJI don’t utilise Occusync for this type of use.
how long the battery can last on the sony battery ?
there's some audio lag ...
the worst part about these videos is they get me all excited for shooting, but i see no shooting in the foreseeable future.... ugh
everybody lies about range !!..... whats the range of this one??
5:23 Talks about it. He did a good job explaining the real world range.
its range is probably accurate, with an empty room, set up to not reflect signals, and isolated from outside interference. it may actually get the 400ft is such a testbed scenario.
In wifi there's a small lag.
That delay about half of a second
Por favor Quiero ver a Jamie en uno de tus vídeos Adam
please work on the focus/resolution on Adam's videos. they got better for a bit, but now they look like SD or worse again.
Ou yeah
this is a first!
i disagree,; this is first
