It is a practical technological innovation for motion detector lights
that drastically improve the safety of your home. And they are very
cost-effective.
There are many effective mechanisms with motion sensor lights but the
most common being technology is the PIRs (passive infrared). Since human
beings emit infrared energy with a wavelength of 9 to 10 micrometers,
most if not all sensors have a sensitivity range of 8 to 12 micrometers.
This is because PIR systems can only detect and be reactive to a sudden,
rapid change in the infrared energy within a specific area.
Motion detector lights are especially handy when it comes to preempting
burglaries and home invasions. One of the more common set-ups involve
sensors turning on emergency floodlights should someone brave to
trespass onto your property during the night,'8 Channel Video Audio DVR

something threatens your home.
