As long as you don't allow the beam to strike the lens head on, the camera should be okay. I have let my 574nm yellow hit the lens at a sharp angle. It set up a diffraction pattern that looked pretty cool. It is in my thread about that laser. At the time it was outputting 36 mW. It is now almost 50 mW with a fan on the driver board and the output transistor and driver IC heat sinked.
