Probably why they are mounted 4 meters high
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)
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 absolutely can.
