Abstract: A system and method trigger a second camera in a camera system to perform an action prior to an object appearing in the field of view of the second camera. The camera system includes the second camera for which a location and a field of view is known, and at least a first device for which a location is known. The method comprises receiving, in the second camera, information indicating that the object is approaching the field of view of the second camera. The received information indicates a location and a direction of movement of the object, and, in response to the received information, triggers the second camera to action prior to the object appearing in the field of view of the second camera by: generating an intra frame or initiating an intra refresh procedure, adjusting one or more image processing parameters, or adjusting an exposure time.
