Because hotlists are flat-file extracts from live databases, they start becoming stale the moment after they are generated. Common practices within law enforcement to mitigate stale lists include:

  • Daily hotlist updates – Hotlists are updated daily or even multiple times per day to mitigate the potential for a nuisance alert or bad stop.
  • Hit alert validation – It is standard policy for officers to review hotlist alerts and run the plate against live systems via CAD or call to dispatch prior to making a stop.

ALPR, while very accurate, can't prevent every nuisance alert:

  • Axon ALPR reads plate numbers with over 90% accuracy. However, it does not identify plate state/province. Because many U.S. states use common character combinations, alerts can result from plates with the correct characters but from the wrong state.
  • ALPR occasionally reads objects that are not license plates, which will also produce an alert if the characters match a hotlisted plate. Axon ALPR works very hard to minimize these occurrences, but they are not completely unavoidable.

Unlike traditional ALPR systems, Axon ALPR is broadly deployable, often across entire patrol fleets. Nuisance alerts that are tolerable among a small number of vehicles may be unacceptable in fleet-wide deployments. The Snooze Alerts feature helps you mitigate the effect of nuisance alerts.

This disables alerting against this hotlist record for the period defined by your agency (12 hours, 24 hours, or indefinitely) across all Fleet 3 systems operated by your agency.
    NoteSnooze applies to the hotlist record, not the plate number. If the plate exists on other hotlists used by your agency, those will still generate alerts.
