| titleOfInvention | A kind of lens structure for surveillance camera |
| abstract | The utility model provides a lens structure for a surveillance camera, comprising a circular mirror body, the mirror body is divided into an upper viewing area, a middle viewing area, and a lower viewing area; the upper viewing area, the middle viewing area, and the lower viewing area Each area includes several small blocks, and the small blocks are lens sheets provided with Fresnel patterns, and all focus on the sensing position of the pyroelectric sensor of the surveillance camera; the middle viewing area is located in the upper viewing area Between the two small blocks on the left and right edges, its left and right ends are surrounded by two small blocks on the left and right edges of the upper viewport. The lens of the present invention is divided into upper, middle and lower viewing zones, wherein the left and right ends of the middle viewing zone are surrounded by small blocks on the left and right edges of the upper viewing zone, which expands the far detection distance of the left and right edges of the lens , make up for the blind area of vision in the middle distance, and meet the needs of surveillance cameras to detect the surrounding environment. |
