Adding IR LEDs to an RPi Noir Cam (WIP)

A little research online seems to indicate the potential for IR LEDs to damage eyesight. Perhaps this is the tinfoil hat squad talking, but I don’t want to take chances with my kid’s eyesight. Thus, we need to wire/program the pi so that it only flips the IR array on during active recording.

A little poking around revealed that the status of the camera (“ready” or “halted”) is held at /var/www/status_mjpeg.txt . I created a simple python script in the same directory called

Lastly, edit /etc/rc.local  with nano to include  python /var/www/  somewhere before exit 0 . That will cause the script to run on startup.

Next up: connect pin 7 to a transistor so that it can control an IR array!
