This is a Case designed for a raspberry pi Zero, an NOIR camera module from Piomoroni and a 40mm 5V Fan.

The used PI Camera Module: https://shop.pimoroni.de/products/night-vision-camera-module-for-raspberry-pi

The 40mm 5V fan is recommended since the IR LED produces a lot of heat when running permanently. It also allows to overclock the pi-zero board without thermal problems. Heat sinks for the IR-LED and the PI ZERO cpu is recommended.

My camera is running the "motioneyeos" linux distribution as a operating system. https://github.com/ccrisan/motioneyeos/wiki

Additionaly I have added a simple reed-Relais to a GPIO pin to switch the IR-LED on and off via the web-browser using action-buttons https://github.com/ccrisan/motioneyeos/wiki/Action-Buttons
