CCTV Mounting Height & Angle Calculator
Mount a camera too high and faces shrink; too flat and the sky blinds it; either way a patch right below stays blind. Enter the height, the distance you want to watch and the lens angle to get the downward tilt, the dead-zone below and where your coverage begins and ends. Planning geometry on flat ground.

A camera at 3 m leaves about 2.8 m blind right below it — cover that with another camera or a doorbell. For a clear face, aim to frame people around a lower spot or add a dedicated ID camera near eye level at the door.
Planning estimate on flat ground — slopes, steps, walls and the real lens all shift it. Do a walk-test and review live footage before final fixing, and leave the actual drilling and at-height work to a professional.
