Title: Type and Working of Motion Sensors

Motion Sensor

What is a Sensor
  • A motion sensor (or motion detector) is the key
    element of your security system, because it is
    the best medium to find someone is in area where
    they shouldn't be.
  • A motion sensor uses one or more technologies to
    detect movement in an area. If a sensor is lose
    footing, a signal is sent to your security safety
    control representative, which connects to
    your survey center alerting you and the
    monitoring center to a hidden thunder in that
    area.

Types Of sensor
  • There are basically three types of Sensors
  • Passive Infrared (PIR)
  • Micro Wave (MW)
  • Dual Technology Motion Sensors

Passive Infrared (PIR)

Passive Infrared (PIR)
  • Hit on body heat (infrared energy). Passive
    infrared sensors are the most widely used motion
    in home security systems. When your system is
    equipped, your motion sensors are activated.
  • Once the sensor warms up, it can sense heat and
    gesture in the encompassing areas, creating a
    protective "framework." If a moving object hunk
    too many lattice zones and the infrared energy
    levels change rapidly, the sensors are pitch.

Micro Wave (MW)
7
Micro Wave (MW)
  • Sends out microwave signals and pitch the
    reflection off a moving object. They cover a
    larger area than infrared sensors, but they are
    vulnerable to voltaic interference and are more
    immoderate.

Advance Dual Technology Motion Sensors
  • Motion sensors can have joined features in an
    attempt to reduce false alarms. For example, a
    passive infrared (PIR) sensor could be mixed with
    a microwave sensor. Since each operates in
    different field of the spectrum, and one is
    passive and one is active.
  • Dual Technology moving sensors are not as likely
    as other types to cause false alarms, because in
    order for the alarm to be generated, both sensors
    have to be tripped. However, this does not mean
    that they never cause false alarms.
