1. A method of autonomous operation for capture devices having an illumination system and an image capture system, comprising: scanning by a capture device of an environment proximate to the capture device for an illumination source operating in a recurring window of time; determining whether illumination occurs in the environment proximate to the capture device within the recurring window of time; if illumination occurs within the recurring window, isolating any existing operational windows of time within the recurring window when the illumination occurs, the existing operational windows each being a fraction of length of time relative to the recurring window; determining a beginning and an end of any existing operational windows; and if time is available within the recurring window, establishing a new operational window within the recurring window.
