That correllates well with my measurement of about 9 ft (left:right) at a radius of 9 ft. If the aspect ratio is 4:3, then you should expect about 60 degrees horizontally x 45 degrees vertically. I wasn't trying to measure the FOV to high accuracy - figure 9 ft. +/- 3 in. - but somehow I doubt that FOV accuracy is going to be that critical a factor with these cameras...
