  1. CPTED
    Crime Prevention Through Environmental Design

    combines the physical environment and sociology issues that sourround it to reduce crime rates and fear of crime.
  2. EMI

    RFI
    Can cause power noise - a disturbance of power - electromagnetic Internference - radio frequency interference

    EMI- lightning, motors. and current difference between wires

    RFI - electrical system mechanisms, flourescent lighting, and electrical cables
  3. Power transient noice
    disturbance imposed ona power line that causes elecrical interference.
  4. Power regulators
    condition the line to keep voltage steady and clean
  5. Fire Classes
    • Fire classes
    • A -Common combustibles- suppression: water, foam
    • B - liquid, petroleum products, Gas, CO2, foam dry powerders
    • C - Elecrical Suppresion: Gas, CO2, foam dry powe
    • D. Combustible Metals - Suppression: Dry powder
  6. Electrostatic IDS
    Electrostatic IDS - creates an electrostatic field balanced between the itself and the object being monitored. If an intruder comes within a certain range of the monitored object there is capacitance change.
  7. Physical Security program - control categories
    deterrence, delaying, detection, assessment, aand respsones
  8. CCD
    CCD - Charged Couple Devices-

    • Receives input light from lens and converts to electronic signal.
    • Images are focused through a lens onto the CCD chip surface, infrared range, - allows the capture of exraordinary details
    • does not recore data
  9. 3 facets of CPTED
    Natural access control, natural surveillance, territorial reinforcement
  10. Window types
  11. Electronic Power definitions
    Ground
    Noise
    Transient noise
    Clean Power
    EMI
    RFI
  12. Types of fires - and Suppression methods
