  3. Project Abstract • Develop a stand-alone paranormal activity detection and recording system for paranormal investigators • Integrate sensors with camera and microphone • Download from device through Ethernet connection • Easy-to-use software for data management and reduction

  4. Problem Statement With currently available equipment… • A person needs to be present to monitor instruments • Multiple sensors might require multiple displays • Getting data on computer may require technical knowledge • Sensors should trigger recording devices—but this is not easy to set up

  5. Solution • A small recording device • Essentially a small computer • Input from motion sensors, temperature sensors, and EMF sensors • Input from camera and microphone • Hard drive for data storage • Firmware that records audio and video when activity is detected • Automatic—can function alone • User-friendly Windows software for downloading data via Ethernet

  6. Design Constraints:Technical • Storage …………..at least 1 hour of data • Camera …………..IEEE-1394 IIDC compatible camera • Compression…….MPEG-1 compression • Noise……………..< 20 dB • Software………….Windows compatible

  7. Design Constraints:Practical • Economic………parts cost less than $700 • Safety…………..UL specification 60950 for information technology equipment • Reliability………can run 2 weeks without rebooting • Size…………….11.75” x 7.5” x 6.75” • Power usage…..will use no more than 72 W

  8. Device Design Serial port to PIC/Sensors Webcam (Firewire, IIDC-compatible) Computer (Needed to download and view data) Ethernet (Only needed when downloading data) Microphone Records data when sensor triggered

  9. Hardware:Device Serial port for sensors Firewire port for camera Power button Ethernet port for downloading data to computer Phone jack for microphone

  10. Temperature sensors (up to 3) Microchip TCN75 Hardware:PIC/Sensors Microchip PIC16876 EMF Sensor Multidetektor II Profi Serial connector PIR (Passive Infrared) Motion sensors (up to 2) Connects to serial port on device

  11. Device Function • After sensing activity, device will record audio/video to hard disk • User will download recorded data via a network connection to a PC • Device can be set up in remote location and data can be downloaded later when user takes device home • If device disk becomes full, recording will cease

  12. Device Considerations • Storing raw video eats disk space: • For 1 hour of raw video • The hard drive is the most failure-prone part of device • We will write to device memory when possible • Device needs to be quiet • Increase sensitivity of microphone • We will use fanless processor • Less powerful, may not be able to compress video

  13. Device Firmware:Design & Considerations • Linux operating system • Free—will not have to buy it • Many open-source projects for video compression, file transfer, etc. • Basic flow chart Files become accessible for downloading at this point Yes No No Yes

  14. Software Interface:Physical Model

  15. Parts • Computer • Motherboard • 120 GB Hard Drive • 512 MB of RAM • Sensors • Temperature • EMF • Motion • Other • PIC • Peripherals (provided by user) • Camera • IEEE-1394 IIDC-compatible • Most webcams comply with this specification • Microphone

  16. Cost • iBot ITX Computer $422.00 • PIR Motion Sensor $ 21.90 • Temperature Sensors (3) $ 4.35 • EMF Sensor $120.00 • PIC $ 7.63 • Assorted Electronics $ 25.00 Total $600.88
