Its not unreasonable for an anti-crime camera manufacturer to expect criminals to paint cameras. It's a movie trope. But anyway, sure would be nice to see some compilation of attack attempts to see what sticks

Idk about paint, but flex seal works

Put a blowtorch on the end of a long stick, maybe one of those two-part sliding ones that they use for pool skimmers and stuff. Melty, blistered plastic doesn't pass light very well.
