I’m a complete noob on the laser world but not an idiot
and yes of course it’s very dangerous, and lasers are even more dangerous (fire of course but also gas, eyes etc…). A 3d printer can catch fire quite easily too if a sensor is faulty, and a lot of cheap lasers and 3d printers are sold all over the world with poor quality electronics etc…
So it’s good to be informed of all its dangers, anyway the question was not about safety and if the OP starts his work and leaves, it’s basically the same thing, so it’s better to explain how to use it remotely and what the dangers are of doing so than to say it’s not feasible.
Now that has been said, I don’t know anyone who stays near a CNC machine (3D printer, laser, milling machine, etc…) for 10 hours, 24 hours or more on long duration jobs…
Alarme, estinguisher, safety enclosure, fume exctractor etc…
My only heating for my house is a wood burning stove which is also very dangerous (monoxide, fume, fire…), but I dont stand next to it all the day long, I got a CO detector and an alarm.
I would be curious to know the percentage of people really staying full time near their CNC when it have to run more than let say two hours…
EDIT: in a way having a camera control & alarm make things safer, than saying stay near your CNC, because no one will do that, after some time they will be confident and will just leave
EDIT2: from a purely technical point of view, the solution I proposed is universal, does not need any change in software or device, is not propriotary, and can be reused later for any other devices. There is just a litlle problem that the drivers need to be signed but this should be done in the year I hope, at least I am working on it
