A Wireless Motion Detector Will Warn You if An Intruder Enters Your Home.
If your home is not protected by an alarm system, or there are areas of
your home that are not covered by by the system, you may want to solve
that problem with the use of motion detectors.
Being wire-free, these detection devices can be placed virtually anywhere without the need to run wires.
Movement is detected by a variety of methods all of which involve the measurement of change that takes place in the area covered by the detector.
If your existing home security system is wireless, you can add
compatible detectors to it.
If your system is hardwired, you can use
these devices as supplemental protection.
Some motion sensors are manufactured to work only with specific systems, others are self contained and operate independently.
Movement is detected by a variety of methods all of which involve
the measurement of change that takes place in the area covered by the
The most usual method of detection is the Passive Infra Red (PIR) system, if an intruder moves into the device’s path the sensor detects the increase in infrared energy.
Most usually a wireless motion detector is fitted inside the
home. Weatherproof detectors for outside use are available but most
usually these are part of an overall security system.
Wireless Motion Detector – Siren or Chime?
The alarm of a self contained motion detector comprises of a siren,
usually between 90 – 120 db. This is quite loud enough to alert you of
an intruder if you are at home.

16 inches, however if your cat or small dog is inclined to jump or climb
they could trigger the alarm.
The other type of pet immune detector
ignores pets under around 60 lbs.
The efficiency of a wireless detector depends to some extent on
being correctly positioned, it may take some experimenting to find the
best place to fit the detector so that it covers the area that you need
