Simply mount it indoors, looking through a window, or mount it on
a roof or the ground inside a box which is separately attached to
the roof or ground.
On the laser issue, I think the previous discussion missed the point
that the laser hsa to be defocused slightly to make aiming easy anyway.
It doesn't have to spread out very far (a matter of a few inches) to
reduce a common 5 mW laser to safe power densities.
