One of the great things about a lot of small sensor cameras is that they’re available in multiple flavours. Most webcams, for example, see both visible light and infrared at night. The Raspberry Pi cameras are the same.
In this video, John Irvin takes one of those small infrared camera modules and a Raspberry Pi 3 Model A+ (buy here) and bundles them up into a night vision camera. It sports a 5″ display and has a compact wireless keyboard.
