Body-worn cameras are an important part of modern policing. These recordings help document police-public interactions, assist with criminal investigations and prosecutions, and provide an additional tool for reviewing complaints, concerns, commendations, use-of-force incidents, and other documented events. Body-worn camera use is governed by department policy, which establishes expectations for when cameras should be activated, how recordings are handled, how long evidence is retained, how recordings are reviewed, and how video may be released in accordance with applicable law and public records requirements.
The Mesa Police Department has used body-worn cameras since 2012, when the department began with 50 cameras. The initial large-scale deployment included officers assigned to the Patrol and Traffic bureaus, beginning with 350 cameras and soon after expanding to 458 cameras.
In 2021, the department’s number of assigned body-worn camera systems increased to 669, allowing the technology to be deployed more broadly across the organization. Body-worn cameras are now used by many frontline, investigative, and specialty assignments, including Patrol, Traffic, SWAT, Canine (K-9), Street Crimes Units, Gang Enforcement, School Resource Officers, the Mental Health Support Team, Mesa Gateway Airport, Task Force assignments, Civilian Investigators, the Bike Unit, and personnel within Criminal Investigation Units. Camera assignments are reviewed and adjusted over time based on inventory, staffing, operational needs, and department priorities. Patrol Sergeants and Patrol Lieutenants were also issued body-worn cameras in 2022.
In late 2024, the department deployed the latest version of its body-worn camera system, the Axon Body 4, continuing the Mesa Police Department’s long-standing commitment to using modern technology to support public safety, accountability, and service to the community. As of May 2026, the department has approximately 684 assigned body-worn cameras in use.
Body-worn cameras support transparency by helping officers, supervisors, investigators, prosecutors, and community members better understand documented events. While body-worn cameras are one tool among many, they provide an important record that can assist with accountability, evidence-based review, and public understanding of police operations.
The Mesa Police Department’s digital evidence system has grown significantly as body-worn camera use has expanded. As of April 2026, the department maintains nearly 4 million digital evidence files, occupying almost 1 petabyte of storage in its evidence management system. Body-worn camera recordings are stored as digital evidence in a secure, CJIS-compliant evidence management system designed to protect the integrity and security of digital evidence. Access to digital evidence is controlled based on authorized roles and responsibilities, while release of records is handled through established legal and public records processes.
As technology continues to evolve, the Mesa Police Department continues to evaluate body-worn camera equipment, evidence management tools, and related features to ensure they remain effective, reliable, secure, and practical for the officers and professional staff who use them. Mesa’s long-term experience with body-worn cameras also provides opportunities to share lessons learned and collaborate with other agencies seeking to improve their own programs.
