Evidence recording with critical officer communication

A server comprising:

• an electronic processor communicatively connected to a memory, a body-worn camera (BWC), a radio device, and a user interface device, the electronic processor configured to
• receive, from the BWC, an indication that the BWC is in a BWC recording state,
• receive, from the BWC, a BWC recording associated with an incident, the BWC recording including a BWC video data and BWC audio data,
• in response to receiving the BWC recording, access an evidence record associated with the BWC recording state, the evidence record being stored in the memory,
• receive, from the radio device, a radio audio recording associated with the incident, a recording ID associated with the radio audio recording, a digital fingerprint that associates and authenticates the BWC recording with the radio device, and a timestamp of the radio audio recording,
• store the BWC recording, radio audio recording, the recording ID, and the digital fingerprint to the evidence record,
• generate a multimedia file having a video track of the BWC video data and an audio track of the radio audio recording, wherein the radio audio recording is synced with the BWC video data using the timestamp of the radio audio recording, and
• output the multimedia file to the user interface device.

A system comprising:

• a server including a server electronic processor communicatively connected to a body-worn camera (BWC);
• and
• a radio device including a radio frequency (RF) interface and a radio device electronic processor communicatively connected to the BWC and the server, the radio electronic processor configured to
• receive, from the BWC, an indication that the BWC is in a BWC recording state,
• in response to receiving the indication that the BWC is in the BWC recording state, initiate a radio recording state to generate a radio audio recording of audio input to and output by the RF interface,
• in response to receiving the indication that the BWC has terminated the BWC recording state, terminate the radio recording state,
• receive a digital fingerprint from the BWC that associates and authenticates a BWC recording of the BWC with the radio device,
• transmit the radio audio recording and the digital fingerprint to the server as part of an evidence record of an incident;
• wherein the server electronic processor is configured to
• receive, from the BWC, the BWC recording including a BWC video data and BWC audio data,
• receive, from the radio device electronic processor, the radio audio recording associated with the incident and the digital fingerprint,
• validate an authenticity of the BWC recording and the radio audio recording using the digital fingerprint,
• store the radio audio recording, the BWC recording, and the digital fingerprint to the evidence record.
