Not that I've heard of.Does green laser disable a PTZ camera? It is kind of an odd question but someone was doing that around here and my camera doesn't want to find the network. There may be more than a green laser involved but I'll check that tomorrow.
If anything maybe it could damage the sensor, running at a higher power, but I don't see how it could fully knock it offline.
I happen to have a green laser, but not necessarily a cam I'm willing to sacrifice.
