Pir through glass
Webb8 nov. 2024 · So, do motion sensor light bulbs work through glass? Unfortunately, no. These sensors use PIR technology which detects object heat-maps. Since glass absorbs infrared energy, these gadgets can’t detect movement beyond it. However, there are a few alternative sensors that work beyond glass obstacles. Webb16 mars 2024 · If your camera uses its IR sensors for motion detection, you won’t get any alerts behind glass. Just like with your night video, the IR is bouncing off your window before it can ever reach a potential human. Your camera can’t detect any motion. Pixel-based motion detection doesn’t have this issue and can work through windows.
