Abstract: In an electronic video monitoring system for security and surveillance, a recording device can adaptively change a bit rate at which a video stream is transmitted so that image quality is prioritized, including above maintaining a continuous real-time transmission. In this way, image quality suitable for security and surveillance can be guaranteed close to real-time, despite changes in video transmission requirements and/or network demands. In one aspect, a frame rate can be lowered to no less than a minimum frame rate, a resolution can be lowered to no less than a minimum resolution, and the frame rate and resolution can be lowered to the minimum frame rate and the minimum resolution, respectively, before allowing an increase of compression of the video stream in view of the change in video transmission requirements and/or network demands. This allows sustaining image quality suitable for security and surveillance.
