Controls: Security

In the field of physical security, lighting is intended to deter or detect intrusions or criminal activity on a piece of real property. Security lights should either be elevated or protected by wire mesh or tough polycarbonate shields. Lamps may be completely recessed from view and access, with light directed out through a light pipe, or alternatively, reflected from a polished aluminum or stainless steel mirror. Properly designed lighting security systems are integral to crime prevention and provide a backup power supply when needed.
