Field of View Calculator
This tool continues the Physical Security Design Flow
Use this step to estimate how much horizontal scene width a camera can realistically cover at the target distance. It translates mounting geometry into a usable horizontal footprint before you continue into coverage-area and spacing decisions.
Calculated values from the previous step can carry forward into this tool, reducing re-entry and preserving design context.
Estimate scene width, depth fit, and coverage practicality from distance and lens angle.
Best for: estimating how much horizontal scene width a camera can cover at a target distance before moving into coverage-area and camera-spacing decisions.
Calculator
Estimate the horizontal footprint of the camera view so lens angle, target distance, and requested scene width stay aligned before downstream spacing decisions.
Results
Model: scene width is estimated from horizontal field of view at the target distance. That footprint is then compared against the requested scene width to show whether the lens is too narrow, well matched, or wider than necessary.
