    I am wondering if anyone has the formula and tested FOV calculations for the Vision +.
    Meaning, if it has a 140 degree lens, you will cover a width of x feet width at altitude of 100ft, y feet width at 200 feet.

    Something like : http://www.pelco.com/sites/global/en/sa ... -calc.page

    I don't know how to calculate the area but I wanted to point out a discrepancy on the Plus camera.

    The front of camera says 140 deg FOV BUT the specs say 110 deg or 85 deg at 1080P (Vision was 140/120/90).

    I did a fisheye calibration using "ProDad DeFishr" and found the Plus 110 is almost identical to the Vision 120
    So the 110 max FOV in the specs appears correct -- not what you see on the front of the camera.
