    摘要： An illumination device for illuminating a scene monitored by a camera (1) and a method of illuminating a scene monitored by a camera, wherein the illumination device comprises a plurality of light emitting elements (5), and an illumination control unit (6). The illumination control unit (6) is arranged to individually control the output intensity of the plurality of light emitting elements (5) based on a camera view direction setting, such that illumination is provided in a view direction of the camera.

    摘要： A power control system (102) for controlling operation of a first battery-powered device (104) positioned at a remote location from a camera (106) is disclosed. The power control system (102) includes a receiving module (312), a retrieving module (314), a comparison module (316), and a transmission module (318). The receiving module (312) is configured to receive at least one of a pan angle and a tilt angle of the camera (106) indicative of a field of view. The retrieving module (314) is configured to retrieve a position of the first battery-powered device (104). The comparison module (316) is configured to compare the pan angle and the tilt angle with the position of the first battery-powered device (104), and determine whether the first battery-powered device (104) is positioned within the field of view of the camera (106) based on the comparison. The transmission module (318) is configured to transmit instructions to control power consumption of the first battery-powered device (104), based on the determination.
