Using PreEvent and Record-After-the-Fact (RATF)
PreEvent Capture
PreEvent supported values are none, 15 secs, 30 secs, 1 min, and 2 mins. You can configure PreEvent
to include audio. You can have audio for the event but not for PreEvent. The evidence is always written
to storage.
As shown in the graphic, you start a recorded event at 2:15 PM and stop it at 2:35 PM. With a PreEvent
Capture time configured for one minute, the recorded event includes video recorded from 2:14 PM to
2:35 PM.
Note: PreEvent only works if your camera is continuously recording.
Audio
Audio is NOT included with PreEvent video unless your agency enables Force Microphone On (page
39). Typically, the V300 Body-Worn Camera only begins to record audio when you start a recorded
event.
