Lens Guidance

2.8 mm: wide area coverage

4 mm: general surveillance

6–12 mm: narrower detail views

Pixel Density Guidance

~20 PPF: detection

~40 PPF: observation

~80 PPF: recognition

~125 PPF: identification

Design Note

Calculated values are planning estimates. Final camera selection should account for mounting height, angle, lighting, compression, motion, shutter speed, and manufacturer-specific optics.
