Review on Infrared Night Vision IR Camera for Raspberry Pi 4, Pi 3b+ Video Webcam with Case - Perfect for 3D Printer Enthusiasts by Austin Wolf

The images attached here show the room's normal lighting and the lights off. Some light comes from the next room, but mostly from the illuminators in this chamber. Note that the blue spatula turns very bright in IR - not shown here, my son has a black shirt that turns white in IR. I didn't spend a lot of time adjusting the focus so you get a sharper image. The camera has tiny screws. So if you have dexterity or vision problems, you may need help. I was pleasantly surprised to find a Pi Zero cable in the box, as well as a long regular Pi cable. One small issue is that the portholes are distinctly red, making it appear in a dimly lit room as if eyes are looking back at you. This might be a plus for some projects, but it's not a hidden darkroom camera.
