For anyone who's actually wondering about this, 100-200mw is extremely damaging to camera sensors(also eyes) and doesn't cause birds to burst into flames from a stray reflection.
Most cheap pen-size laser pointers sold as "5mw" are actually 100+. As a general rule, if you can see the beam brightly when doing star pointing it's somewhere in this range
(but if Parent's laser is one of those sealed-tube Co2 lasers, it'll never touch the camera sensor itself because the beam doesn't go through glass. Might crack it after a couple seconds though)
I did always wonder if the sort of green laser pointer that could light matches would wreck the sensors.
The biggest use of these cameras in the UK is in car parks so that predatory parking companies can fine you £60 for going a nano-second over the time you paid for.

It's a green stacked diode laser. Collimation is poor but at a couple of meters any kind of sensor will be slag in a few seconds.
I would be interested if anyone is prototyping vehicle mounted lidar with machine vision discrimination.

It absolutely can.
