An in-car video apparatus and method is provided where a real time continuous video supplied by a vehicle-mounted camera and an audio microphone is processed for storage in a memory in a time-sequential manner for a pre-set time interval to create a time-delayed video stream. Upon activation of the in-car video system by a law enforcement officer (which occurs at an arbitrary reference time), a vehicle-mounted recording device records the time-delayed video stream to create a video recording of the events captured by the video camera. Because the time-delayed video stream is recorded rather than the real time video stream, the start time of the video recording precedes the reference time by the pre-set time interval. The invention provides an ability to create a complete record of a police-citizen encounter, including the initial incident that prompted the officer's subsequent activation of the in-car video system.
