I have a long driveway (12-14 metres) with a side door right at the end. I want to put a camera above the door facing down over the door and out towards the street. I need help selecting the right lens size. The camera I have I mind is the 2342 turret.
My first thought is to get a 6mm lens since the driveway is long and narrow. However I'm worried that I need to get the door inside the field of vision.
If the horizontal angle of vision is around 45 degrees, and the aspect ratio is around 16:9, does that mean I'll get 9/16 of 45 degrees (27 degrees) on the vertical?
Any recommendations?
