CPTED
Crime Prevention Through Environmental Designcombines the physical environment and sociology issues that sourround it to reduce crime rates and fear of crime.
EMIRFI
Can cause power noise - a disturbance of power - electromagnetic Internference - radio frequency interferenceEMI- lightning, motors. and current difference between wiresRFI - electrical system mechanisms, flourescent lighting, and electrical cables
Power transient noice
disturbance imposed ona power line that causes elecrical interference.
Power regulators
condition the line to keep voltage steady and clean
Fire Classes
Fire classesA -Common combustibles- suppression: water, foamB - liquid, petroleum products, Gas, CO2, foam dry powerdersC - Elecrical Suppresion: Gas, CO2, foam dry poweD. Combustible Metals - Suppression: Dry powder
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.
Physical Security program - control categories
deterrence, delaying, detection, assessment, aand respsones
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
3 facets of CPTED
Natural access control, natural surveillance, territorial reinforcement
