What’s the best way to mount a hidden camera?
Mount the camera inside the object. Point the lens facing out of the hole in the object. Make sure that the camera fits, and that it doesn’t look obvious. If you think that the object will be moved around at all, consider using superglue to hold the camera in place.

How to calculate the horizontal field of view of a camera?
With some simple goniometry, one can obtain: So with this formula you can calculate the horizontal field-of-view of your camera. Of course measuring the vertical f.o.v. goes exactly the same way except that you then need to view the object in its vertical position.
How to calculate the distance from the camera to an object?
For example, let’s say I place a standard piece of 8.5 x 11in piece of paper (horizontally; W = 11) D = 24 inches in front of my camera and take a photo. When I measure the width of the piece of paper in the image, I notice that the perceived width of the paper is P = 248 pixels. F = (248px x 24in) / 11in = 543.45
