The Technical Services Division (TSD) protects human life and property by enforcing laws related to the regulation of security guards, private investigators, scrap metal dealers, sex offenders and job applicants for specific occupations that require statutorily mandated background checks and fingerprint clearance cards. TSD also assists in the enforcement of laws by hosting and supporting the Arizona Criminal Justice Information System (ACJIS) which provides criminal history information to every law enforcement agency in the State and serves as a conduit to the National Criminal Information Center (NCIC). TSD’s oversight of these regulated areas also serve to deter criminal activity related to vulnerable populations such as children. TSD provides vital support to the state of Arizona and its citizens by developing and coordinating scientific, technical, regulatory and support services essential for the functioning of Arizona’s criminal justice system. TSD houses four regional crime laboratories that provide scientific analysis of evidence, technical crime scene assistance, secure storage of evidentiary items, training, and expert testimony to criminal justice agencies in the state. It also houses the department’s three regionally based operational communications (dispatch) centers throughout the state which provide statewide radio dispatch services to AZDPS, emergency medical services and other law enforcement dispatch centers. TSD also oversees information technology, telecommunications and wireless systems which is responsible for state-wide radio services that not only serve AZDPS but also serves other state agencies such as the Department of Transportation and Game and Fish.
