The mounting frame is generally made of metal, which has high strength and is not easy to damage. The mounting frame is hinged to the mounting base 22 through a connecting rod 11 and a first connector 111. When the pitch adjustment is performed, the camera 21 can rotate up and down with the rotation center of the first connector 111.

[0045] In the embodiment of the utility model, the camera assembly 20 includes a camera 21 and a mounting seat 22. The mounting seat 22 is made of stainless steel and can be made by casting, machining, stamping and other processes, and is used to install and fix the camera 21.

[0056] See also Figure 1 , Figure 2 and Figure 6In some possible embodiments, the rain sensor is a piezoelectric rain sensor 50 .

[0057] The piezoelectric rain sensor 50 uses the piezoelectric effect to measure rainfall. When raindrops fall on the sensing surface of the sensor, pressure is generated on the sensing surface, causing the sensing surface to deform. Since the sensing surface uses piezoelectric materials, the deformation will generate an electrical signal, and the size of this electrical signal is proportional to the size of the raindrop and the impact force. By measuring the size of this electrical signal, the amount of rainfall can be calculated. The piezoelectric rain sensor 50 can be purchased directly from the market. Its structure and working principle belong to the existing technology and will not be repeated here.
