What will your policy be? When will cameras be used? / When is an officer mandated to use it? Will all interactions will the public be recorded, e.g., helping with a flat tire? Responding to any crime?
How will your agency handle and manage the video? Will the officer be able to review his/her own recording for training/officer safety purposes? Will supervisors regularly review the footage?
How will your agency store the video? Videos require a huge amount of space on a server. In fact, it can be more expensive to store it than to intall the cameras in the first place. What is your archival plan? Compress after 30 days? Destroy after a year?
