I would like to start work on the Helmet Camera, and hoping to have the ability to transmit to a smart phone.
If I am correct, this is what drone cameras do. I do not have a drone. Have never flown a drone.

If anyone here is knowledgeable in this area, do you believe this is a possibility?
And if so, any recommendations on hardware?

Sony Action cameras can do that..

Thanks for the lead.
Although, as cool as that seems to function, it appears to be a little too large to fit in the Helmet Cam.

well maybe this... not sure about the range...

Thanks metal. Those look to be on target.
I do see they need Wi-Fi, to live broadcast.
Probably not much trouble, if able to connect at whatever location one might be.
(like a convention setting)

It seems drone cameras have antennas, so I'm guessing they don't need Wi-Fi (?)
I'll have to do some more reading on both of these.

Backup cameras. That seems like another good possibility.

I love the idea of having a couple Marines patrolling a Con with their helmet cameras feeding back to a Gorman-style display on a table.

That is one of the reasons Drones came to mind.
Ive seen Drone races, with multiple units each transmitting back to their respective pilots.

If that can be done, it doesn't seem a far step to have multiple helmets do the same.

I actually tried it. Drone FPV video feeds run in 2.4ghz and 5ghz frequency bands. There is not enough power to go far and it is mostly line of sight. Done tried. I did find some higher gain antennas, however, that is not to say we have a comms squad guy that had a high antenna to boost signal.

The way most TV crews do it is they have a Van with the remote satellite uplink and then they have local broadcast units and they are not more than 50 feet or otherwise line of sight away from things.

The other option that might be easier, is to have one person that multiplexes or combines 4 signals into one video and then streams that to youtube, and then at the table a live feed for youtube or facebook is pulled up. The only problem with that is it assumes:
good cellular signal on both ends (wireless internet access at cons is iffy and very insecure at best)

The backup cameras I liked because they were RCA connection, ran at 12vdc, allowed use of common batteries and offshore/offgrid power solutions, and the lower definition did not require high horsepower to manipulate or store.

The multiplexer is a cheap option with backup cameras. Big rigs, rock crawlers and other folks with unique setups use those as early warning detection setups. Then for each connected user to not neccessitate wires they would require a broadcast unit on a separate channel that is combined with the squad comms officer who then runs it multiplexed and then streams that to a facebook or youtube channel

The pi can take that feed and should be able to broadcast it

So we need to upscale the rca to an hdmi signal:

So far I can only find solutions using a pi camera.

Another option is to go through a full on streaming device:

My research back then as is the case now you are looking at a 1000USD plus investment in hardware to get a proper working solution.

I recommend an older sony action cam. gopros do it to but gopro is always disabling old aps so you have to buy new stuff. I do this on my motorcycle. you can get a good one for like $40 now. you just need the app and youre good to go. sonys are also a better shape. theres a bunch like this. https://www.ebay.com/itm/225023367364?e ... SweUFioYtH

My biggest concern is finding something that will fit in the helmet camera and line up with the Pentax lens.
The space inside the camera is only about 1.5 inches square.

ill try to remember the tiny one i had for that. it was kind of a dev kit. sony might work but there also a tiny gopro cube and a ton of others, just needs wifi I guess.

Just pulling these up at random, but was thinking along these lines...

Perhaps running the battery and antenna to the Lobster Plate Pouch.
But, not too sure if it is as simple as it looks, to become operational.
Would have thought finding out all that is needed for these to work, would be a simple task,
but it's not working out that way.

I did this some 14 years ago. The challenge is the space you have to work with. As such, I think the best approach is to separate the camera and the capture/transmission method. Look into CCTV bullet cameras that you can then feed to either a capture or transmission hardware that you can have stored in a pouch.

I try to stay off the 2.4/5ghz allocation. It is too full and noisy at conventions.

All the Ghz range frequencies have very low penetration qualities through concrete prevalent at most all convention structures.

Shortwave and high frequency allocations are best.

This item I have used and the transmitter is line of sight only.

hey here is one that is self contained they are using it on this tiny RC car but it should be easy to strip it down and just use the board/camera/battery...

it's ready to go and links with FVP monitors..

https://www.diatone.us/products/diatone ... 9441675351

Here is a video of it working and you can see how tiny it is...

It uses 5.8ghz for video and 2.4ghz for the remote. Great on line of sight setups and looks super fun.

Unfortunately it will have transmission issues. I need to have a good discussion with a news van tech guy amd see what they run.

Must be getting interference from the structure. Drake check your camera.

That's not better, must be the structure.
