Abstract
Methods and systems for controlling a camera can involve automatically setting an exposure control for a camera based on data obtained from the camera and using a synchronized infrared flash for video recording by the camera with the exposure control automatically set for the camera. The exposure control can include a managed fixed exposure time controlled with automatic gain correction by the camera. The exposure time for the camera can be fixed. A gain can be monitored, and the exposure time adjusted when an average gain attains a maximum value or a minimum value with changes to ambient light.
