edge).
Inactivity time ms:
Specifies the minimum time between two consecutive
triggers. If a trigger is received before this time is expired
it will be discarded.
Median filter size:
Allows to set the window size over which the median
filter is calculated. Can be set from 3 to 91. Default value
is 13.
Enable median filter:
Enable the median filter for the digital inputs when it is
slow and/or noisy. Disable the filter to catch a short and
fast trigger.
GateTimeMax:
It allows setting the value, in milliseconds, of the
maximum period between start and stop of the trigger.
The values may range from 40 to 30000 (=30 seconds).
Trigger Shift Time:
It allows setting a delay to be applied to the start and stop
triggers. This may be useful in order to insert a delay
between trigger detection and processing initialization.
Specify value in milliseconds. Default 0 is no delay.

CHECK LIST
The ANPR features 2 check lists called A and B. The configuration of check list A and
B are identical. These check lists can also be referred to as a white-list or black-list.
These check lists can be stored either on the internal flash memory of the ANPR or
on a remote ftp-server. The check list is loaded into RAM memory upon ANPR start-
up.
It is possible to modify and update in real time the number plate lists located in the
ftp-server or in the internal flash memory of the ANPR unit. To load the updated list
into the RAM memory, press the 'Reload List'-button.
Syntax Check List file contents
The check list file A and B containing number plate lists, must comply with the
following syntax:
Vehicle Number plate; Country; Comment string
The semicolon (' ; ') is used to separate the fields. Irrelevant spaces are ignored.
The Country field should contain the 3 character capital code. See for a complete list
of country codes:
www.nedapidentification.com/anpr-countries
The comment string maximum length is 64 characters. Longer comment strings will
be truncated. Every line (including the last line) must be terminated with a carriage-
return.
Example
46HVR9;NLD;Ferrari 599 GTO
ZLSZ17;NLD;Fiat Cinquecento
AB123HK;ITA;
Note
The maximum check file
size is 200kbytes. This
approximately holds up to
10000 number plates,
depending upon number
plate and comment lengths.
