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

Shopping List
Raspberry Pi (Cana Kit) $79.99Logitech HD 270 $27.99PIR Sensor $4.99Powered USB Hub $35.00Keyboard, mouse, and monitor $0.00
Total Cost: ~$150.00
Setup
IR Sensor
General Purpose Input/Output (GPIO)◦Python GPIO library
Set mode Define which pin to expect inputGPIO_PIR = 18
Motion detected when GPIO state == 0
IR Sensor
SMS
Short Message Service (SMS)◦Create new Gmail account◦[email protected]
server = smtplib.SMTP( "smtp.gmail.com", 587 )server.starttls()server.login( '[email protected]', ‘password' )
server.sendmail( 'Raspzilla', ‘[email protected]', 'Motion detected at home!' )
Video & Live Stream
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
Initial Results
Storage
Default directory ◦/tmp/motion◦Cleaned on reboot
Dropbox◦Dropbox uploader script◦Authentication not on RPi
Uses Dropbox API for authentication◦Issues getting this to work
WinSCP◦Manually transfer files◦Not automated
Timeline
◦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
Security
Security
RPi Credentials◦Username: pi, Password: raspberry
default startup doesn’t ask for credentials. ssh still does.
IP Tables◦“firewall” for Linux systems
Passwords stored plaintext◦motion◦Python SMS
Issues
Motion daemon run at startup = bad idea◦100% resource utilization
Initially refusing to use a webserverNot understanding video formatsStream-able video vs. motion capture
videoFirefox only browser streaming videoAudio| and \ not functioning on keyboard
