1. Description
The Bollard ANPR Camera is intended for use with all Videofit and SNAP
ANPR processors although they can also be used with just a DVR if
required. These cameras are capable of very high recognition accuracy
since their free-standing design allows them to be positioned in the ideal
location for perfect plate imaging.
The main features of the cameras are:-
•
Vandal-resistant design with 8mm replaceable Lexan window
•
Full height lockable door for ease of installation & servicing
•
Built-in pulsed infrared illumination for day and night operation
•
Simple adjustment of zoom and focus
•
Adjustable camera pan & tilt
The camera is also available in a dual version which includes a high
resolution colour overview camera designed to capture full colour images
of the vehicle. With these models, the overview camera is also provided
with simple zoom and focus controls.
2. Siting the Camera
The camera is designed to cover a single traffic lane only, typically 3
metres wide at the capture point. Any attempt to cover two traffic lanes
with a single camera will result in the ANPR processor missing vehicles
and mis-reading plates.
The camera should be positioned adjacent to the target traffic lane - do not
attempt to view across one lane to view another. Always try and position
the camera close to the head-on position but not exactly perpendicular to
the plate, since unwanted reflections from the infrared illuminator can
occur in some situations. The ideal angle of view is between 5º and 30º
from the normal path of the vehicles.
