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 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.            Files become accessible for
                                            downloading at this point
