Any tips for installing a security camera indoors but so window glare won't obscure the image?

Answer 1

The placement is important, but so too is the lighting behind the lens, directed at any subject.

Most loss of features is caused by back light against the subject, creating the subject to be sillouette/blacked out.

If your Q involves shooting film through a window, the window would have to be coated non reflectively, or the cam lens would have to be at the glass. If the intent is shooting in daylight you may still have the issue of backlight

Answer 2

Actually, a circular polarizing filter fitted to the camera's lens would probably do a better job of cutting the glare/reflection. You could also change your camera mounting point and put the whole thing behind a sheer black cloth much like a sniper's hide for shooting from inside a room.

Answer 3

You can install it when 2 people to do so. One inside and one outside. Until you get the right angle, you can do that, and not too close to your window: not to be seen from outside.
