Automatic License Plate Reader Technology Alerts within milliseconds if a vehicle is suspect Features multi-level alarm levels for prioritization—Wants, Warrants, Amber Alerts Can be configured with a variety of different camera ranges Can be configured to remotely alarm to an email recipient Can operate with data from different sources and be updated on the fly LPR technology can be deployed overtly or covertly The Command Center Networks all cameras together in one integrated system  Mobile systems  Fixed systems  Covert systems  Centralizes data to support investigations and intelligence gathering needs  Alarms transmitted remotely to pagers, cell phones immediately  Easy Search Functions  Innovative use of LPR Technology By law, convicted sex offenders must register with the law enforcement agency in their community. Geofencing protects children and alerts law enforcement of violations immediately . • Hot list can be loaded with all sexual predators in a geographic area. • GPS coordinates can be set for each school, nursery, etc. • Radius can be set from plots to create a virtual fence. • Reads tags outside the fence, but alarms within the fence for immediate enforcement. Lessons Learned Infrastructure assessment  IT staff needed to set up/maintain equipment and databases  Distribution of equipment and deployment strategies  Regional LPR Networks  Barriers in your organization, government or community  Hassan Aden Alexandria (VA) Police Department Hassan.aden@alexandriava.gov 703-838-6360 Ext. 1274 Graphics and slides in this presentation cannot be used or recreated without consent of the research team.

LPR’s effectiveness depends on the quality and quantity of data it accesses. LPR’s effectiveness depends on how it is used.  What we know: ◦ LPR is faster, more efficient, and more accurate than the manual approach.  What we don’t know : ◦ Whether LPR is effective in reducing crime. ◦ How LPR use will affect police legitimacy.  Randomized controlled field evaluations ◦ Testing the effectiveness of LPR use at hot spots ◦ Replication of PERF LPR experiments, just across two jurisdictions.  Legitimacy and legality tests ◦ Random sample survey of 2000 households. ◦ Scenario testing with legal experts.
