CONCEALED SURVEILLANCE CAMERA SYSTEM FOR LIGHTING DEVICES

摘要

A combined concealed surveillance camera and photosensor control system is contained in an outer housing of predetermined configuration and dimensions to replace the existing light sensor or photosensor control unit of a public, commercial, or residential lighting fixture, replacing the function of the existing control unit in turning the lighting fixture on and off based on detected ambient light level, and also providing a concealed surveillance camera system drawing power from the lighting fixture power supply so that the camera is on continuously while the lighting fixture is turned on and off based on the detected ambient light level.

主权项

1. A combined surveillance camera and photosensor system for replacing a photosensor unit of an existing lighting fixture, comprising:
an outer housing having at least a first window, a second window, and a base portion configured for releasable mating engagement in a photosensor unit seat of a lighting fixture after removal of an existing photosensor unit; the base portion having at least two electrical contacts configured for mating engagement with corresponding electrical contacts in the seat when the base portion is mounted in the seat; a power switching control module and a surveillance camera module mounted in the outer housing; the power switching control module having a controller and at least one photosensor aligned with the first window to detect ambient light level outside the housing, the at least one photosensor having an output connected to the controller which varies based on detected ambient light level, and the controller being configured to control connection between the electrical contacts in the base portion to connect a power source for the lighting fixture to at least one light source in the fixture when the detected ambient light level is below a predetermined minimum light level; and the surveillance camera module comprising a surveillance camera having at least one lens facing the second window.
