Plan the evidence zone, not just the camera location
Placement determines whether a camera records useful evidence or merely a wide picture. This cluster connects lens choice, field of view, mounting geometry and pixel density to real entry, driveway and plate-capture decisions.
Coverage & Focal Length Calculator
Model horizontal FOV, scene width, pixels per foot and required focal length.
Driveway Focal Length
Choose lens width around the actual lane or identification zone.
2.8mm vs 4mm
Understand the coverage-versus-detail tradeoff.
Best Height for Face Identification
Balance tamper resistance with usable facial geometry.
How Far Can 4K Identify a Face?
Use scene width and PPF instead of megapixel marketing.
Driveway License-Plate Camera
Choose a dedicated plate-capture architecture rather than relying on a wide overview camera.
Driveway Plate-Capture Angle
Plan a narrow vehicle choke point with controlled angle.
Varifocal vs Fixed Lens
Decide whether on-site optical tuning is worth the premium.
Front-Door Field of View
Frame the face path and package zone without wasting pixels.
Driveway Field of View
Choose scene width from the evidence objective.
Driveway Mounting Height
Understand how height and target distance interact.
Lens for a 50-Foot Target
Translate distance and target-zone width into lens requirements.
