Hotlists with millions of entries (for example, 2.5 million or more) require much more CPU processing power and memory than smaller hotlists. Turning on the Simplematcher tells Genetec Patroller™ to ignore the NumberOfDifferencesAllowed portion of the MatcherSettings.xml file, which considerably reduces the processing load on the Genetec Patroller™ in-vehicle computer.

Before you begin

To ensure that the system does not generate too many false positive hits, turn off OCR equivalence in the ALPR matcher.

What you should know

When Use Simple Matcher is not enabled in the Genetec Patroller™ Config Tool, the Genetec Patroller™ will automatically use the simple matcher by default if the number of entries in the plate list exceeds two million entries. In this case, common and contiguous characters “fuzzy matching” is not available.


  1. Open Genetec Patroller™ Config Tool.
  2. Go to Operation > Hotlists and then turn on Use Simplematcher.
  3. Click Apply.
