Title:
SURVEILLANCE CAMERA SUPPORTING HYBRID LIGHT SUPPLEMENTING
Document Type and Number:
WIPO Patent Application WO/2020/103525
Kind Code:
A1
Abstract:
A surveillance camera supporting hybrid light supplementing, comprising a front cover (220), a secondary lens (213), a light supplementing lamp mounting plate (211), a low-beam light supplementing lamp (2121), a medium-beam light supplementing lamp (2122), and a high-beam light supplementing lamp (2123). The conical secondary lens with a light supplementing lamp placing hole (2132) at the bottom and having a planar light-emitting surface is mounted in a lens mounting cavity (221) in the front cover (220) by means of UV dispensing; a light supplementing lamp mounting through hole (222) is formed in the bottom of the lens mounting cavity (221); the light supplementing lamp is mounted on the light supplementing lamp mounting plate (211); the light supplementing lamp mounting plate (211) is fixed to the bottom of the lens mounting cavity (221) and located outside the lens mounting cavity (221), so that the light supplementing lamp faces the front cover (220), penetrates through the light supplementing lamp mounting through hole (222), and is placed in the light supplementing lamp placing hole (2132). By setting the low-beam light supplementing lamp (2121) as the white-beam light supplementing lamp, the surveillance camera can photograph an image corresponding to the actual color of a photographed object nearby, and by setting the medium-beam light supplementing lamp (2122) and the high-beam light supplementing lamp (2123) as the infrared light supplementing lamps, a black-white image of the photographed object at medium and long distances can be clearly photographed.
