A method of automatic activation of a responder camera to begin capturing a video can be performed by a computing device. The computing device receives an indication of a location or an event. The computing device determines a geographic area associated with the location or event. The computing device receives a dispatch acknowledgement from a responder, where the dispatch acknowledgement indicates that the responder is at the geographic area or that the responder is en route to the geographic area. The computing device automatically sends a camera activation signal to a responder camera associated with the responder in response to receiving the dispatch acknowledgement from the responder. The responder camera is configured to begin capturing a video in response to receiving the camera activation signal.
