Arizona State University is planning to study the best way for police to use those cameras.
The ASU Center for Violence Prevention and Community Safety will be conducting a year long study observing the Tempe Police Department and the police department in Spokane, Washington.
The research team has been asked by the Justice Department to come up with guidelines for police to implement while using the cameras.
They hope the study will help identify the best practices for departments to use.
Researchers plan to look into the impact and consequences of body-worn cameras and will evaluate whether or not they actually work as a violence reduction tool.
The study is made possible by a $500,000 grant from the Laura and John Arnold Foundation, which is based out of Houston.
It is unknown how ASU will conduct its study, but results are expected in a little more than a year.
