I had a conversation recently with an officer about cameras like these, and his recent testing of one for the department, and his concern was the similarity of the cameras acuity and his own. For instance, if he can see through the glare in a window but the camera can't, the recording might be used to say that he didn't have probable cause. Vice versa -- if the camera can see things he can't, a post-incident review might well say "why did you do X when _clearly_ you can 'see' blah blah".
