Phase 5: Configure hotlists
Turn on SimpleMatcher
SimpleMatcher reduces the LPR matching mechanism in order to minimize the number of
false hits that can occur. For example, if a license plate includes a “B” character, the LPR
matcher may also see this as an “8”. This can result in a number of false hits. Turning on
SimpleMatcher reduces the chance of the LPR matcher mistaking a “B” for an “8”, as well as
for other OCR equivalent characters.
1 Open Patroller Config Tool.
2 Go to Advanced > Hit hotlist, and turn on SimpleMatcher.
For more information, see "Hit hotlist" on page 222.
Modify LPR matcher settings
You can reduce or turn off OCR equivalence when using very large hotlists. High OCR may
result in plate reads matching many other plates in the hotlist because of the OCR
equivalent characters.
Set the number of OCR equivalent characters in the MatchersSettings.xml file in the Security
Center program folder. You also need to open the Server Admin console to apply the
changes, and then restart the Directory.
1 In the Genetec Security Center program folder, open MatchersSettings.xml.
2 Make changes to the PerLengthSetting OCR equivalents and differences:
• NumberOCREquiAllowed=0, 1, or 2 (zero turns the feature off).
3 Save the file.
4 From a web browser, open the Server Admin console by typing ///genetec/console#/Commands.
5 From the All commands page, click UpdateAutoVuGlobalSettings.
6 Close the Server Admin console.
7 Froma web browser, open the Server Admin by typing ///genetec.
8 Click the Directory tab.
9 Under Directory status, click Restart to restart the Directory.
10 Close Server Admin.
Managing large hotlists with multiple LPR Managers
By default, Security Center uses a single process for every LPR Manager on the system. For
example, even if you have ten different LPR Manager roles on the same computer, Security
Center uses a single process called GenetecLicensePlateManager32.exe to run them. This can
cause CPU memory issues if you are using large hotlists on several of the LPR Managers.
To better manage the memory load caused by the large hotlists, you can configure Security
Center to create a separate process for each LPR Manager.
