Nice, finally the open burglary map comes closer ;-)
I have 2 remarks:

1. regarding guard there might be some overlap with this tag:

2. Isn't there one parameter missing to deduct the actual area covered
by a camera? I'd think you needed 3 values: direction the camera
points to (in 3d, e.g. azimuth and  altitude) plus the field of view
or focal length. This is of course purely theoretical because the
cameras might be able to move and most mappers won't probably be able
to add high precision orientation data (usually you will have to
estimate these values).
