How Do Security Systems Work?

The moment one of your security sensors gets breached, either by an intruder, fire or gas leak, the alarm goes off.


  • Self Monitored response: This option means you receive the notification on your mobile or any other smart device and respond to the alert/alarm however you see fit.
  • Professionally monitored response: Once they are notified of a possible emergency, a security expert will reach out to you through the control panel or your home telephone to confirm if it’s an actual emergency.

In an emergency or no response from you, the security company contacts the appropriate response team in your locality to get to your home. If it’s a false alarm, the company turns off the alarm from their end.

What Causes An Alarm System To Go Off?

Installing a security system in your home requires you to place various kinds of sensors in specific areas. It is these sensors that trigger your alarm when breached. Here are some types of sensors and how they activate the alarm system:

Motion Sensors

The infrared motion sensor type detects intruders by comparing the heat signals of moving objects in their field. The sensor gets triggered once body heat is detected. Many motion sensors now have pet immunity to prevent the alarms from being triggered by pets being pets.

Window/Door Sensors

Magnetic in nature, this type of sensor comes in two parts, with one installed above the door or window while the other placed directly on them. The opening of the door or window separates the sensors, which automatically triggers the alarm.

Emergency sensors

These are typically used to secure your property against fire, flood or gas leak. They are positioned in vulnerable places and trigger the alarm when necessary.
