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. Runs in your browser.
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.

The mounting geometry that decides whether a camera reads a face or just films the sky: how high to fix it, how far to tilt it down, the dead zone under it, and keeping backlight and IR wash out of frame.
SecurityCCTV Coverage Planning in India (2026): Think in Coverage, Not Cameras
Plan a home CCTV scheme by the coverage it produces, not the number of cameras you buy: map choke points, overlap so every camera is watched by another, keep entry-to-exit continuity, and set the pixels-per-metre each zone actually needs.
