Which bicycle cameras are suitable for all weather 11+ hours food delivery cyclists
Answering because I'm not making a product suggestion.

There aren't any.   Most of the action-style cameras go for about 2 hours on their internal battery.

Personally I have run a single gopro 3 on a 9AH external USB battery for over 12 hours, but this is vulnerable to water entering the camera housing, and the continual vibrations of riding bouncing the plugs in their sockets.

You'll also need a 64 GB memory card per shift per camera, or some way to empty them all overnight while you sleep.

Many action cameras lack datestamp functions too, so its hard to prove that events happened at a specific time/date.

Plus a camera makes your bike more of a theft target.  So if you do this consider a chest harness.

All the action cameras are poor-to-crap at night.  I know of no night-vision action cameras.



Alternatives

Make yourself visible - that's


multiple front and rear lights
spread those lights around the bike (high and low positions)
white spoke reflectors (the yellow ones are not half as good as these)
reflective white-side tyres (not white-walls)
high-vis top/jacket with reflective piping or panels.


Other suggestions:


Learn where to not bike at night - narrow bridges, bad roads, anywhere the yobs/hooligans congregate..... just use another route even if its longer.
Don't be afraid to say "We can't deliver to that address after dark"


If you're stuck on mapillory best to look at their requirements or suggested camera list.   From their website, its an app-only driven service so you're out of luck with that requirement.  Better drop this, or run your cellphone camera separately just for this service.
