A bendable sheet of silicon can hide 95 percent of infrared light, rendering objects essentially invisible to heat-sensing night vision goggles or infrared cameras. Black silicon is made by growing silicon crystals at various heights on a silicon wafer, creating what looks like a dense forest of needles.
Can night vision cameras see through curtains?
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.

Do night vision cameras give off light?
IR or night vision cameras use infrared light to illuminate images in the dark.

Can phone cameras see UV?
Light of shorter or longer wavelengths doesn’t excite our eyes’ receptors so we can’t see anything beyond red (infrared) or violet (ultraviolet) on the electromagnetic spectrum of light.The cell phone camera is more sensitive to light than human eyes are, so it “sees” the infrared light that is invisible to us.
Can a thermal camera see a fart?
You cannot detect a fart on a thermal imaging camera. Thermal cameras cannot detect fart since the gas is nearest to room temperature. Other than this, fart is not dense enough, and for that reason, it can’t enroll on the thermal camera. Gases from humans and animals are simply similar instances as breathing at large.
