What are the advantages of a motion detector?

Sharing is caring!

The advantages of a motion detector can be numerous. Indoor or outdoor motion detectors are generally used for security purposes to detect an intrusion. But they can also be used for the lighting comfort of his home for example.

You certainly have many questions about the advantages of a motion detector. Does a motion detector work in the dark? What is a motion detector? How does a motion detector work? What are the different types of motion detectors?

This article will answer all your questions about the benefits of a motion detector.

The main advantages of a motion detector

An indoor or outdoor motion detector is a safety device that can signal any passage in front of its sensors. The main goal is to detect a malicious person who will break into your home. When a person passes in front of the sensors a signal is automatically triggered via the lighting of the lamps or via an electronic alert.

In addition, the alert can be sent to your central security system in case of a potential threat.

The motion detector can also be programmed to activate the wifi surveillance camera of your security system. It is an effective system when you are away.

Indeed, some systems even offer live streaming of images on your smartphone. Motion detectors coupled with surveillance cameras are a way to secure your home effectively.

Some connected mobile cameras have multiple motion detectors that allow the camera to be directed where motion has been detected. This is a great way to secure a wide angle of your home or garden.

In addition, light and sound motion detectors are also very effective.

Indeed, statistics prove that illuminated places have a much lower crime rate than dark places. Properly lighting your home and garden greatly reduces possible hiding places for burglars.

Similarly, the alarm siren scares criminals in the majority of burglaries.

Finally, some motion detectors are multifunction and incorporate brightness, infrared, heat or humidity sensors.

How does a motion detector work?

Motion detectors or PIR (Passive Infra Red sensors) are composed of sensors that detect a change in a detection area.

It all depends on the type of motion detector you have but their detection areas range from 2 to 25 meters.

Different types of motion detectors exist such as optical detector, radio wave detectors or infrared detectors for example.

Infrared detectors pick up changes in infrared waves or heat, while radio frequency detectors use microwave signals.

Finally, exterior or interior motion detectors are present in our environment without paying attention to them such as the automatic opening of the doors of a store entrance.

What types of motion detectors are there?

  • Infrared or PIR: Detection of heat sources
  • Radiofrequency: Wave passing through walls and doors
  • Ultrasound: Detects objects in the room (fires when an object moves)
  • Camera sensor: People detection

In brief: The advantages of a motion detector

  • Report any detected motion
  • Report door or window opening and abnormal pressure on doors and windows
  • Trigger a siren, light, or video when opening a door or window or when passing in front of a detector
  • Sound and light motion detectors limit burglary in most cases
  • Warn you in case of intrusion of burglars or animals
