ANPR ACCESS | INSTALLATION GUIDE
Configuration

1000ms interval to expire). The images subsequently
acquired and processed must be related to the new event.
The MaxTimeTransit value should be set to the highest
possible value while of course complying with the
specific installation requirements. Setting a too low
MaxTimeTransit value means less images are processed
for the same vehicle, which leads to lower reliability in
OCR reading.
Min Time Same Plate (Enable Multi Out Same Plate = 0):
It represents the minimum time in milliseconds during
which the camera will not generate an event even if the
number plate has already been recognized. In other
words, during this time a previously recognized number
plate does not need be in the ANPR field of action in
order to generate another event. If the vehicle remains in
the ANPR field of action, the same plate recognition event
is generated only once.
Min Time Same Plate (Enable Multi Out Same Plate = 1):
It represents the length of time in milliseconds that must
elapse before generating a new recognition event
associated with a plate that was already recognized. In
this case, if vehicle remains within the camera field, then
the ANPR system will repeat generating a recognition
event every Min Time Same Plate.
Image Selection Mode:
Indicates the selection mode of the image containing the
recognized plate. Possible values are: FIRST-PLATE, LAST-
PLATE, BIGGEST-PLATE or BEST-LUMINANCE.
Min Numb Plate Read:
Minimum number of read images to validate a transit. The
allowed values are 1 to 3 and is used only in FREE RUN
mode. This filter is useful to avoid false readings caused b
patterns that may confuse the camera.
Advanced features
Enable Kemler Codes (ADR) Recognition:
Select to enable or disable the recognition of ADR license
plates (if supported by the firmware library). ADR license
plates are special license plates used for transport
vehicles with hazardous goods.
Join Special Plates in a Single Result:
Select YES to join special plates reading in a single result.
Enable Vehicle Classification:
If enabled, the vehicle classification is made considering
the reflective panels. This processing could slow down
the system.
