Lens Selection Helper

Part of a Design Flow

This tool continues the Physical Security Design Flow

Use this step to convert the validated pixel-density requirement into a practical focal-length choice that still supports the intended scene width. Calculated values from the previous step can carry forward into this tool, reducing re-entry and preserving design context.

This flow includes both Free and Pro tools. Unlock Pro to complete the full sequence.

Determine focal length and lens class based on scene geometry.

Best for: converting pixel-density validated distances into a real lens choice that delivers the required field of view.

Calculator

Enter working distance, target width, and sensor width to estimate the practical focal length needed for the scene.

Distance to Target (ft)

Target Width (ft)

Sensor Width (mm)

Results

Enter values and press Suggest Lens.

Model: the raw focal length is calculated from scene geometry, then adjusted using the prior pixel-density requirement so the lens choice stays aligned with the desired detail level.
