Security Lights & Motion Sensors

Security lighting is the best preventative measure that you can take for home security. This may include outdoor motion lights or other such lighting for burglary deterrence and nighttime security purposes. Security lighting can be used in residential, commercial, industrial, institutional, and military settings. 

Other lights may be activated by sensors such as passive infrared sensors (PIRs), turning on only when a person (or other mammal) approaches. PIR activated lamps will usually be incandescent bulbs so that they can activate instantly; energy saving is less important since they will not be on all the time. PIR sensor activation can increase both the deterrent effect (since the intruder knows that he has been detected) and the detection effect (since a person will be attracted to the sudden increase in light). Some PIR units can be set up to sound a chime as well as turn on the light. Most modern units have a photocell so that they only turn on when it is dark.
