ANPR ACCESS | INSTALLATION GUIDE
Configuration
12/36
The General Settings page contains the following configuration fields:
Enable Engine:
It allows enabling/disabling the processing of the images
grabbed by ANPR. The parameter takes two possible
values: YES or NO. If set to NO, the device is switched to
stand-by mode and its infrared illuminator is disabled. It
will ignore any external trigger. The infrared illuminator is
only momentarily enabled if the Camera OCR page is
being accessed.
Acquisition mode:
It allows selecting the system operating mode. Select
FREE-RUN, TRIGGER-START-STOP, TRIGGER-START-TIME,
TRIGGER-START-FREE-RUN-STOP or TRIGGER-ETHERNET.
Site Address:
This field can contain an alphanumeric string, such as the
address of a system location. This string is available as
%SITE_ADDRESS TAG and can be sued in the text value
field of the Save Image action.
TCP message after ftp actions: With this parameter you can enable sending a TCP
message after ftp actions (ftp save image and ftp save
DB).
Maximum fps:
Sets the maximum grabbing frame rate. Use "0" for no
limitation.
Filter static plates:
Allows to avoid sending plates if the same plate is
detected multiple times, e.g. when a vehicle stops in the
camera field of view. Use with care.

CAMERA OCR
This page configures the Frame Grabber Settings.
On the left side of the page 'live' video images are shown. The red rectangle on the
image border represents the search plate window. It is possible to set size and
position of this window in Plate Reader page.
General
Grab Mode:
Here it is possible to set the image grabbing mode and
camera related settings. Three image grabbing modes are
available: AUTOIRIS, SINGLE-POINT, and MULTI-POINT.
Result position:
In this section, it is possible to specify, inside the live
image, the position of the OCR reading results and the
unit's work parameters. The allowed values are: TOP-LEFT,
TOP-RIGHT, BOTTOM-LEFT, BOTTOM-RIGHT and DISABLED.
Autoiris
Automatic grabbing mode. Using autoiris, images show better lighting uniformity
during the whole day, while using the Multi-Point mode image lighting varies more.
It is advisable using the autoiris mode while using the Multi-Point mode whenever
autoiris can't provide for satisfying performance.
Max Shutter us:
Maximum exposure time in microseconds. This value
should be set based upon the maximum vehicle speed.
Too long an exposure time would produce blurred images
and result in lower reading performance. Maximum
exposure time value should therefore set to a low enough
value so as not to get blurred images. During low light
hours, the higher the exposure time the higher chances
are to get images where the vehicle is visible.
