Camera
We use the AXIS P3275-LVE. This camera comes in two variants for the focal length. If the distance from the gate to the camera is under 40 feet, then use the 10mm variant, otherwise use the 29mm variant. License plates require a minimum pixel width of 120.Mounting
Mount the camera directly on a flat, corrosion-resistant surface as shown below. This provides the best protection against water damage.
Follow AXIS installation instructions carefully to avoid damaging your cameras.
Requirements
Distance
The ideal distance for the camera is- 30 feet from the gate (or where a gate would be)
- 9 feet above ground
Examples
Plates have sufficient pixel width and distance is ideal.
Angles
Horizontal and vertical angles should be around 22.5 degrees. Following the distance recommendations above makes this easy to achieve. Avoid angles that are too sharp or too shallow.
Misreads
Sharp angles cause misreads because the camera cannot see letters clearly.Overlapping Vehicles
Shallow angles cause multiple vehicles to overlap, collapsing them into one. The system deduplicates vehicles using bounding boxes. Vehicles that overlap more than 30% are treated as one.Examples
Angles are not too sharp or shallow, vehicles do not overlap.
