[0002] With the development of modern technology, more and more smart home applications are being used, such as smart doorbells, which use passive infrared detection technology to automatically capture images as the human body moves. The passive infrared detection technology used requires two key components.

[0003] For example, a Fresnel lens for a smart doorbell with the authorization announcement number "CN211345182U" solves the problem that the performance of the existing Fresnel lens for smart doorbells and the camera cannot keep up with people's needs. The above-mentioned upper part of the light collector is symmetrically distributed with two groups of first light collectors, and the lower part of the light collector is symmetrically distributed with second light collectors with a width consistent with the width of the first light collector. The upper and lower light collector structures are arranged to solve the problem that the general smart doorbell is difficult to trigger in a straight line in some scenes, thereby ensuring the detection sensitivity. Considering that the surface of the Fresnel lens of the existing smart doorbell is exposed to the outside, it is inevitable that dust will fall on the surface, which will affect the upper and lower light collecting effects of the surface. Manual cleaning is troublesome, which affects the user experience. Utility Model Content
