  1. S.W.A.T(Security Watching All the Time) Jeff Shin Tyler Stubbs Paul Kasemir Pavel Mayyak

  2. Overview Project Objectives and Purpose Approach Sub-systems Division of Labor Schedule Risks and Contingencies

  3. Project Statement Home Security and Safety Detection of intruders Intruder prevention by alarms and lights Recording of home activity Generate reports (logs) Allow remote access

  4. Motivation for Implementing Allow home owners to always know what is happening in their house Allow remote access to the system Fend off intruders

  5. System Diagram

  6. Control System Communicates with each sensor Communicates with Visual Station Records data from sensors Responds to events (trigger alarm)

  7. Control System Main control processor: ATMega128 RF link: ZigBee Wireless Internet: TBD Ethernet module Data Storage: SD cards Alarm Trigger: Standard IO Programming: C/C++ using Eclipse Visual Station: Connected via Serial

  8. Sensors Infrared motion detection Magnetic proximity for doors/windows Glass integrity sensor Temperature sensor

  9. Sensors • Simple control processor: ATMega8 • RF link: ZigBee Wireless • Magnetic sensors: HALL effect switch • Glass Integrity: Glass Break Detector • Temperature: Analog or Serial • Infrared Sensor: Self-Designed

  10. Visual Station Contained within a laptop Continuously updating sensor values Graphically displays information Monitor and control system settings

  11. Alarms Lights Noise (siren) Email

  12. Power Sources All parts of the system will be powered by AC All digital components and chips will run at 3.3V

  13. Extras • Control the coffee pot or oven • Lock doors • Camera nodes • Real time graphs of each sensor • Other Control Nodes (Turn on lights, open garage door) • SMS notification

  14. Division of Labor Programming: Paul and Pavel PCB Designs: Paul and Pavel Analog Circuitry: Jeff and Tyler Power Implementation: Jeff and Tyler Sensor Construction and Implementation: Jeff and Tyler Documentation and Testing: All

  18. Risks/Contingencies • Wireless communication adds to sensor interface complexity*Remove wireless link from sensors. Use simple wires. • Number of remote units increases complexity*Decrease number of remote units

  19. Risks/Contingencies • PC interface functionality of graphing and displaying data*Simplify the Visual Station graphing functionality • Remote access via web server*Simplify the web server or use the Visual Station instead

  20. Questions?? Security Watching All the Time
