The Digital Technology Investigations Unit is responsible for conducting investigations of offenders that utilize computers and computer technology for the purpose of exploiting children. The Unit conducts proactive and reactive investigations into endangerment of children. These cases most often come in the form of child pornography or luring of a child. The Unit is designated as the Internet Crimes Against Children Task Force (ICAC) for the State of New Jersey. Unit members conduct investigations, provide investigative assistance to other law enforcement agencies, conduct computer forensic services in the field, and provide public awareness through internet safety lectures to adults and youth.

The Digital Technology Investigations Unit was originally named the High Technology Crimes and Investigative Support Unit. During late 1996, and officially in January 1997, the New Jersey State Police gathered a group of investigators who had an aptitude for computers. They were provided specialized training and began conducting investigations. They were the first unit in the State of New Jersey to specialize in computer investigations and one of only a handful across the United States. The unit was responsible for conducting investigations into all crimes that utilized computers, computer technology, and telecommunications and that knowledge of computer technology was essential for the perpetration, investigation or prosecution. They were also the only unit conducting computer forensics in the State.

As internet usage within the state increased, the unit received a corresponding increase in complaints. The number of child endangerment, internet fraud, and computer intrusion cases increased to the point that it was determined that multiple units were necessary to increase the efficiency of the investigative response. In May of 2004 the Cyber-Crimes Unit created to investigate computer intrusions, virus, and fraud. The High Technology Crimes Unit was renamed the Digital Technology Investigations Unit and dedicated to child exploitation on the internet.
