The purpose of this thread is to document the Measured Horizontal FOV of all future Vantrue dashcams I receive for test & review.
I settled on this method because all you need is a wall, and a yardstick.
It’s easy to duplicate so anyone can confirm & verify my measurements.
The hardest part to maintain accuracy / consistency is to place the camera lens in the exact same location every time, (50cm from wall).
Height doesn’t really matter as long as it matches the yardstick, (28cm).
After obtaining the FOV measurement in centimeters, plugging two known measurements into a right triangle calculator will provide the Horizontal FOV in degrees.
