Scripts to use Raspis for home surveillance.
Uses a Raspi Nano to take a picture every few seconds, encrypts it with a public key, and uploads it to a server. On a second bash stream, it takes the same picture and scales it down to thumbnail size and uploads it unencrypted.
Uses a Raspi Nano and some sensors to detect an opened door, movement and light. Posts current state changs to the server every second or so.
