How Does A Motion Detector Work?
An alarm system is a great way to provide extra protection for your home.
There are plenty of options available for you
to ensure your home’s safety. So don’t take chances.
Protect your family with a home security system that will
safeguard your most precious valuables, and the people you
love.
Wireless Motion Sensor Home Security System
What are they?
Motion detectors spot the movement in areas covered by the
security sensors. Motion detectors transmit high frequency
radio wave signals. They give a warning that someone is
entering into your home.
Different kinds of motion detectors & how they work:
Infrared Sensors:
Motion detectors use infrared light to detect heat changes,
i.e. when a person moves across this light it detects them
with the help of the infrared sensors. If a person moves in
the range of the motion sensors, the alarm is activated.
Infrared sensors are cheaper than microwave sensors and
ultrasonic sensors. Infrared sensors are generally smaller
and very reliable.
Vibration Sensors:
It detects a person through vibration. Many car alarms have
this feature to alert the owner that something has bumped
into their car.
Photoelectric Sensors:
Some motion detection systems use lasers and photoelectric
beams. The laser is shot across to the other side of the
room or doorway. If the laser is interrupted the unit’s
alarm signal is activated.
Ultrasonic sensors :
They use a frequency around 30kHz. The transmitter bounces
the waves of walls, furniture, windows and ceilings and when
the room has stabilized, the alarm is armed.
Acoustic Sensors:
They can detect the energy produced by any kind of sound,
including breaking glass. In the case of breaking glass from
window intrusions, the pattern of the sound emitted is
detected.
