    Objectives: On-officer video camera (OVC) technology in policing is developing at a rapid pace. Large agencies are beginning to adopt the technology on a limited basis, and a number of cities across the United States have required their police departments to adopt the technology for all first responders. However, researchers have just begun to examine the effects of OVC technology on citizen complaints, officers’ attitudes, and police–citizen contacts. Methods: This study examines officer behavior and perceptions of camera technology among 100 line officers in the Mesa Police Department during police–citizen encounters over a 10-month period. Experimental data from 3698 field contact reports were analyzed to determine whether being assigned to wear an OVC influences officer behavior and perceptions of OVC technology. Results: Bivariate and multilevel logistic regression analyses indicate that officers assigned to wear a camera were less likely to perform stop-and-frisks and make arrests, but were more likely to give citations and initiate encounters. Officers were also more likely to report OVCs as being helpful if they wore a camera and in situations where they issued a warning or citation, performed a stop-and-frisk, and made an arrest. Conclusions: Our results provide important insights into the consequences of OVCs on police behavior and suggest that officers are more proactive with this technology without increasing their use of invasive strategies that may threaten the legitimacy of the organization.
