Abstract
Methods and apparatus, including computer program products, implementing and using techniques for reducing bitrate from a monitoring camera. A first input is received that identifies first regions of an image representing a camera field of view. The first regions contribute significantly to the bitrate. A second input is received that identifies second regions of the image. The second regions contain information that is deemed to be of little visual interest to a user of the monitoring camera. Third regions of the image are determined. The third regions are regions where the first and second regions overlap at least in part. Video encoder settings are applied to force skip blocks in at least some of the third regions, thereby reducing contributions to the bitrate from the third regions.
