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