Abstract

A camera light-leakage prevention device comprises a lamp plate and a shading member. The central part of the lamp plate is provided with a through hole for a lens passing through. One side surface of the lamp plate, encircling the through hole, is provided with several infrared lamps. The shading member is fixed to the lamp plate and contains an annular shading body positioned between the through hole and the infrared lamps. The shading member is arranged between the infrared lamps of the lamp plate of the camera light-leakage prevention device and the through hole for the lens passing through so as to isolate the infrared lamps and the lens, and light of the infrared lamps can be prevented from penetrating the lens.

Description

technical field [0001] The invention relates to a light leakage preventing device for a camera. Background technique [0002] Existing ceiling-mounted spherical cameras are usually provided with infrared lamps to illuminate the imaging area. However, if the infrared light leaks and the infrared rays enter the lens, the image quality of the image captured by the camera will be affected. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a camera light leakage preventing device for preventing infrared light leakage. [0004] An anti-light leakage device for a camera, comprising a light plate and a light shielding member, the light plate is provided with a through hole in the middle for the lens to pass through, a side surface of the light plate is provided with a plurality of infrared lamps around the through hole, the light shielding member It is fixed on the lamp board and includes an annular light shielding body located between the throug...
