Joe,
The lens is listed as a 4.9 mm, F2.8 lens(I had to search but found it on one of the CMUII sites). The target area is 4.86 mm x 3.64 mm. for a diagonal of nearly 1/4", the listed specification for this device. Plug in the numbers for the diagonal and the focal length and it comes out to about 60 degrees. Since the aspect ratio for this camera is 4:3, the horizontal look angle is less than 60 degrees and the vertical is even smaller. This of course is in a perfect world and the lens in this camera is not self compensating for focus, distance to pickup, etc. so the FOV (field of view) will vary from camera to camera. According to my lens calculator (fudging for the tiny pickup area, my calc only goes down to 1/2") FOV (horizontal) is 22-25 ft. at 20 ft from the camera.
