Testing and SimulationOverview

• Circuit simulation impossible digital circuit
• Prototype/packaged comparison superfluous
  digital components
• Exception temperature sensor
• System testing
• a test Dr. Reeses house
• ß test Kemper
• Tests also performed with continuous recording

superfluous was the word of the day on August
1, 1999.

a TestSummary

• PARDS setup at Dr. Reeses house
• System triggered 31 times (i.e., motion sensor
  detected motion)
• From 600 pm until 1040 pm, triggered when Dr.
  Reese entered room
• Light was turned off at 1040 pm
• Unknown causes of system trigger after this time
• System ran smoothly entire night

P.A.R.D.S.Reliability

• Mini-ITX computer requires fan for continuous
  operation
• With fan, firmware has never crashed
• Also tested on desktop
• Never crashed

ParaStorRemote Interface

• Problem
• Recording device has no direct interface
• No way to modify settings without monitor
• Solution
• ParaStor provides interface
• User can control settings such as image format,
  video buffer size, and sensor polling frequency
• User can view real-time images and data
  downloaded by ParaStor
