The Automated Regional Justice Information System (ARJIS) was created as a joint powers agency (JPA) to share information among justice agencies throughout San Diego and Imperial Counties, California. ARJIS has evolved into a complex criminal justice enterprise network used by 71 local, state, and federal agencies in the two California counties that border Mexico. The secure ARJISnet intranet integrates more than 6,000 workstations throughout the 4,265 square miles of San Diego County. There are more than 11,000 authorized users generating more than 35,000 transactions daily.
ARJIS is used for tactical analysis, investigations, statistical information, and crime analysis. The ARJIS governance structure promotes data sharing and cooperation at all levels for member agencies, from chiefs to officers to technical staff. ARJIS is now a division of SANDAG (San Diego Association of Governments).
ARJIS is responsible for major public safety initiatives, including wireless access to photos, warrants, and other critical data in the field, crime and sex offender mapping, crime analysis tools evaluation, and an enterprise system of applications that help users solve crimes and identify offenders. ARJIS also serves as the region's information hub for officer notification, information sharing, and the exchange, validation, and real-time uploading of many types of public safety data.
