A motion sensor (or movement detector) is the linchpin of your safety system, because it's the main device that detects when somebody is on your house when they should not be. A movement sensor uses one or multiple technologies to discover movement in an area. When a sensor is tripped, an indication is delivered to a hazard in your house to your safety program's control panel, which connects to the center, alerting you and your observation centre.

The following guide will answer all your questions regarding motion detectors: the different kinds, correct positioning, and also how to use them.

The Role of Motion Sensors On Your Home Security

The main intention of motion detection is to sense an intruder and send an alarm to your control panel, which alerts your observation centre. Sensors work when you are not home, or whenever you tell the machine. Some security systems may be programmed to document events by means of a security camera when movement is detected.

Motion detectors stand guard, prepared to respond to different situations, such as motion on your living space, windows or doors being opened or shut, or a broken window. Motion sensors can:

Alert you in the event Your teenager breaks curfew

Trigger a doorbell when someone approaches the front door

Alert you if children enter restricted areas in the home, like the basement, work out area, or medication cabinet

Conserve energy by using motion sensor lighting in unoccupied spaces

Inform you if pets go into areas in which they're not supposed to become

Passive Infrared (PIR)

Passive infrared sensors are the movement in house security systems. When your system is equipped, your movement sensors are triggered. Once the detector warms up, it may detect heat and movement in the surrounding areas, creating a protective"grid" When a moving object blocks a lot of grid zones and the infrared energy levels change rapidly, the sensors are tripped.

MircoWave (MW):

Sends out microwave pulses and measures the reflection off a moving object. They cover a bigger area than infrared detectors, but they are vulnerable to electrical interference and are more expensive.

Wireless motion sensors can have combined features in an attempt. For instance, a passive infrared (PIR) sensor can be combined with a microwave sensor. Since each operates in various areas of the spectrum, and yet one is passive and one is busy, Double Technology movement sensors are not as likely as other types to trigger false alarms, because in order for the alert to be triggered, both detectors must be triggered. But this doesn't mean they cause false alarms.

Working with Your New Wireless Motion Sensor

Area Reflective Type:

Emits infrared beams. Using the reflection of these beams, the sensor measures the distance to the individual or object and detects whether the item is inside the designated area.

Sends steps the reflection off a moving object and out pulses of ultrasonic waves.


Detects vibration. These easily produced at home or can be bought. A home made vibration sensor uses a small mass on a lever, which can be triggered by a switch to an alarm when it vibrates. Homemade motion sensors can operate, but they can also be unreliable.

Wireless Motion Sensors:

Now, most movement detectors are wireless. Wireless sensors are extremely simple to establish. They don't need drilling, and they communicate with another security system elements .

Most contact movement detectors are passive infrared detectors. They activate an alarm when the door or window is opened while the machine is armed.

A passive infrared detector can be installed to ignore creatures around a certain weight. A dual technology motion detector is significantly more immune to false alarms brought on by animals since it requires two detectors to be triggered in a fashion dependent on the manufacturer. They are sometimes installed to ignore a huge animal or multiple tiny creatures without setting off a false alert. Some pet resistant motion detectors have a sensitivity level which may be corrected for households with very busy animals.

Combines video cameras using innovative signal processing. Some recordable movement sensors begin recording when they feel movement. Cameras controlled by movement detectors can help save you memory by not recording countless hours of worthless footage--they just capture the important things.
