The monitoring camera has 3.6 mm and 3.2 mm. What is the difference?
It refers specifically to the size of the lens, which can be distinguished by the depth of the field and the size of the image. The smaller the lens is, the smaller the image is, and the larger the image is, the larger the scope is. This is something that you have to think about before you install the camera, the size of the object, the object spacing, the size of the lens, the size of the CCD, the size of the CCD.
