Is it possible to create an inexpensive and reliable system for transmitting videos from workers' helmets online?

Question

Arduino

At the construction site where I work, there is a need for online monitoring and recording of work processes using portable video cameras mounted on workers' helmets. Workers about a hundred people, reinforced concrete structures.
How possible is it to implement such a solution without resorting to complex and expensive systems like mesh networks?
Is it possible to implement such a solution in the conditions of work in the basement?

There is nothing permanent at the construction site, only temporary.
Reinforced concrete digests and jams Wi-fi, especially the basement.
Even a smartphone with a powerful battery will not last long in shooting and video broadcasting mode.
Workers will need to carry a decent-sized battery.
The wires to the camera will break.
Infrastructure will be required to recharge this entire economy.
Cameras must be vandal resistant.
Wi-fi network bandwidth, real, will require at least 1 Gbps.
All equipment will need to be mounted and configured.
The signal from the cameras will be lost - hundreds of hours to set up this whole system.
That's all I can think of for now, but it's far from exhaustive.
Wake up. It's not expensive, it's super expensive.
For these purposes, I use ordinary cameras on ordinary poles. Well, sometimes our project manager "flyed" around the construction site on a quadcopter.

Answer 2

Can.
It will be necessary to implement a mini-server to which the video stream from several cameras will go, and then the transcoded (compressed) video will be transferred to the web

Camera models in the studio. If they are wireless and support wifi, onvif, then you can create a wifi mesh, in extreme cases, just try to poke access points, but then the video will be interrupted for a few seconds when moving from the zone of one access point to the zone of another. We connect all cameras to wifi, each we distribute our own static ip address.
In order for everything to work in real time (with a delay of 1-2 seconds, which will always be on ip cameras), you need to assemble a wifi network on equipment that supports 802.11r and 802.11k.
Record from cameras to the video surveillance server, connecting all cameras as onvif cameras.
There is another option - if the cameras can record on an sd card, then buy sd cards, then, when all the workers hand over the equipment, manually transfer from the cards to the storage. But this is not online control.
There is a third option - to take cameras that can upload the contents of their sd card to an ftp server. In the area where the equipment is stored, after the shift, leave the cameras. There, make one wifi router good to pull all the cameras. They, when no one is working, will themselves merge video from cameras to an ftp server, for example. But it's not online anymore.

Answer 4

on helmets, conventional cameras + radio transmitter. hang on the Akum belt from the UPS)
in some place at the construction site of the receiver. transfers it all to the computer. On the computer video capture card.
PROFIT!
