Home security summary

A fan of automated house objects, you dream of building a smart and functional home, in which all your electronic objects would be connected: connected speaker, connected socket, automatic lighting, video surveillance, not to mention the presence or motion detector. Exactly, let’s talk about it! What is a motion detector used for? What are its advantages and disadvantages?

What is a motion detector used for?

As its name suggests, a motion detector is used to detect the presence of intruders in your home. The presence detector is activated when movement is detected. The device then sends you a signal and an alert, possibly via a remote monitoring service provider who can notify the police or request the intervention of a security guard.

The latest generation models of presence detectors today not only reinforce your security but also your daily comfort. Some models even allow you to program your connected objects. Your lights, your speaker, your radiators, or even your air conditioner can thus be switched on, as soon as you are in a room equipped with presence sensors.

For the most efficient devices, presence sensors can detect movement 20 meters from their location. Mobile or fixed sensors can measure the temperature and detect a foreign body, as well as analyze the brightness or ambient humidity to detect a risk (violation of property, break-in, burglary, etc.)

How to choose a presence detector?

Our advice is very simple: the choice of a presence detector model depends on your personal expectations.

In this case, a detector can fulfill several functions:

  • Trigger a siren at the slightest movement
  • Prevent intrusions in your absence
  • Film intruders (CCTV recording)
  • Identify your pets without triggering an alarm
  • Simulate a presence at home (via lighting for example)
  • Automatically direct a moving camera to the detection area
  • Raise or lower the temperature of a room at the slightest detection of presence, etc.
