Physical and Environmental Security

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
