There is no single correct height
The right height keeps faces large enough while protecting the camera and maintaining the required scene. Doorways often need a different height than parking lots or warehouses.
Test before final fastening
- View a person at the target distance.
- Check hats and hooded faces.
- Test the night image.
- Confirm ladders or lifts can service the camera safely.
Avoid steep angles
A very high camera aimed sharply downward may capture movement but lose facial detail. Add a lower identification view where necessary.
