This is open to all radio amateurs operating with Denton County.

These cameras are quite simple; they consist of a Raspberry Pi, a Pi Camera, and a POE “uninjector”. The Pi cameras are configured to run a shell script as a systemd service. This shell script will take a picture every 10 seconds using raspistill, and then sort it into three directories: hourly, daily, and weekly.
