Ordered two of them. The first was always in night mode. Only the IR emitters were controlled by a photocell. error out of the box. The seller seems good but only one problem with the product. Second, the mechanical day/night IR switch worked, but the lack of a manual UVC gain control makes it unsuitable for large area night lighting (assuming at least a crescent or city light is used for the HM2131 chip). , I have other modules that see excellent nighttime detail passively, as opposed to that pure black passively). My microphones didn't work either. Can be good for those who use it in a small indoor space.
