1. Residential Surveillance with IR Sensor & Raspberry Pi Maxine Major April 22, 2014

2. Goals (Quadsheet) • Decisions • Shopping List • Implementation • Setup • Components • Timeline • Security • Issues • Demo Overview

3. Quadsheet

4. Home Security System • Camera • Motion sensor • Reporting • Short Message Service (SMS) • Live Webcam • Recorded images/video Goals

5. Type of Camera • USB webcam • IP camera • “stealth” cam • Functionality • Video & Sound • Record in dark • Motion detection • Webserver • Store/serve images/video • OS vs. Arduino Decisions

6. Sensor • Infrared • Passive Infrared (PIR/IR) (changes in heat) • Ultrasonic (frequency changes / microwave) • Tomography motion detection (detects through walls!) • Photoelectric beam (lasers) • Hybrid • Single point of failure • Pyroelectric Decisions

7. Decided on: • USB camera • Daylight recording only • Video & Sound • Raspberry Pi • Linux-based Raspbian OS • Passive Infrared Sensor • Motion detection only • Motion detection to trigger video Decisions

8. Raspberry Pi CanaKit • Power supply • HDMI Cable (not needed) • Breadboard & prototyping materials • Wi-Fi dongle • 8GB SD card w/NOOBS • Case • $79.99 Shopping List

9. PIR Sensor • Good reviews • 5V works off RPi3.5V • Missing jumper • $4.99 Shopping List

10. Logitech HD 270 • USB Webcam • Minimal reported issues • Works well with motion • $27.99 • http://elinux.org/RPi_USB_Webcams Shopping List

11. Raspberry Pi (Cana Kit) $79.99 • Logitech HD 270 $27.99 • PIR Sensor $4.99 • Powered USB Hub $35.00 • Keyboard, mouse, and monitor $0.00 • Total Cost: ~$150.00 Shopping List

12. Setup

14. General Purpose Input/Output (GPIO) • Python GPIO library • Set mode • Define which pin to expect input GPIO_PIR = 18 • Motion detected when GPIO state == 0 IR Sensor

15. IR Sensor

16. Short Message Service (SMS) • Create new Gmail account • raspzilla@gmail.com server = smtplib.SMTP( "smtp.gmail.com", 587 ) server.starttls() server.login( 'raspzilla@gmail.com', ‘password' ) server.sendmail( 'Raspzilla', ‘phonenumber@carrier.com', 'Motion detected at home!' ) SMS

17. Motion • /etc/motion/motion.conf • Webcam port 8081 • Control port 8080 • framerate 10 • ffmpeg_video_codec msmpeg4 • max_mpeg_time 600 • lighttpd(pronounced “lightly”) • Webserver • Small memory footprint • VLC Media player Video & Live Stream

18. Initial Results Video & Live Stream

19. Default directory • /tmp/motion • Cleaned on reboot • Dropbox • Dropboxuploader script • Authentication not on RPi • Uses Dropbox API for authentication • Issues getting this to work • WinSCP • Manually transfer files • Not automated Storage

20. Setup Raspberry Pi • New Out Of Box Software (NOOBS)  Raspbian • Configure Wi-Fi • Static IP • Install motion • Set up PIR sensor • python • Print message to console • Short Message Service (SMS) • crontab run python at startup • python initiates motion at detection • Shell commands • Offsite storage Timeline

21. Security

22. RPi Credentials • Username: pi, Password: raspberry • defaultstartup doesn’t ask for credentials. • ssh still does. • IP Tables • “firewall” for Linux systems • Passwords stored plaintext • motion • Python SMS Security

23. Motion daemon run at startup = bad idea • 100% resource utilization • Initially refusing to use a webserver • Not understanding video formats • Stream-able video vs. motion capture video • Firefox only browser streaming video • Audio • | and \ not functioning on keyboard • (Shift+3 #: £, “ = @,) Issues

24. Demo
