Python-based motion detection and still/vid capture and delivery for Raspberry Pi 3

Hooked up two PIR motion sensors to a Pi 3. Now when either detects motion, the Pi’s camera will take a still shot and send it to an an email account, as well as take a slo-motion video and send that to a dropbox account.
