Abstract
The invention discloses a remote control system for a video monitoring lamplight power supply. Only one light source needs to be arranged, and the emergence angles of brightening light rays and the incidence angles of external light rays can be kept consistent on the premise of not arranging an additional controller; and secondly, self-adaptive control of a light amplifier in a video monitoring system is realized according to the change of ambient brightness, namely, the light amplifier is started when the brightness is insufficient, and is shut down in a high-brightness state. The acquired environmental brightness is extracted from a current video of a monitoring scene through a video analysis technology, so that obtained brightness parameters are accurate and reliable; and moreover, remote control of a power supply loop is realized through the software interface of an intelligent power supply remote control center server without arriving at a site, so that convenience is brought to operation.
Description
Technical field
