If it's CW then I'd be surprised if 2mW was enough. But if it's pulsed (i.e. mode-locked or Q-switched or some such) then it might. It would need to be focused down, but the camera's lens might well do that. 488nm used to mean Ar+. Some of the little air-cooled ones had powers of a few mW. But most Ar+ lasers were big beggars, ranging from several hundred mW up to 'large frame' ones delivering 10-20W. With appropriate focusing they would damage house bricks and would set fire to your tie unfocused if you were careless enough to dangle it in the beam.

The short answer -if I understood Valvebloke correctly- is YES.

Ah, then I hadn't made myself clear. For a 2mW CW laser the short answer is NO (I imagine - don't sue me if I'm wrong though).

This is a concert laser apparently. In one of the follow up comments someone points out that that may be anything from <500mW up to 40W (!!). In any case much, much more than 2mW.
