  • Door and window alarms
  • Cameras
  • Motion detectors
  • Water sensors
  • Carbon monoxide detectors
  • Alarms

These are the basic components of a security system. Below, you will learn exactly how some of these devices work.


Multiple Sensors

All security systems are equipped with multiple sensors, which are capable of detecting different types of motion. The glass break and front door sensor is set up to monitor these specific areas and when the sensor is triggered an alarm is signaled. For example, a small box is attached to a window and when an intruder breaks the glass or tries to raise the window to gain access into the home, the sensor is triggered.

Ultrasound sound waves are put on standby and if the intruder enters the home, the reflection pattern will be interrupted. An alarm signal is sent to the homeowner’s source device and security system’s access center.

The motion detector is equipped with infrared sensors, which is capable of sensing infrared energy. The human body emits infrared energy, so the sensor will be able to pick up anyone that enters your home unwanted. The intruder must pass through the detector’s field of view, before the infrared sensor is triggered. It is important to note that an immediate alarm is not always triggered, because the security system is set up to allow the homeowner to respond, by entering the security code into the control panel.

How the Alarm Works

Once your system has detected an intruder, motion or carbon monoxide, your system will automatically trigger the wireless alarm. When the alarm goes into effect, a variety of different actions will be performed. Although each system is different, the actions presented below are the most common.

  • A loud siren will sound
  • Flashing lights may be displayed
  • A telephone auto-dialer will automatically call the authorities or security company

This aspect of the security system has a number of different purposes. First, the loud siren and strobe lights will usually scare the intruder and cause them to flee. This can also wake you up, if you’re in the home. If not, this will definitely alert your neighbors, who will also be able to take action. Finally, the auto-dialer can be used to notify the authorities, security company, you or your family members.

In order for your security system to be effective, it is vital for your alarm to be efficient.


In the end, the functionality of home security alarm systems is thoroughly impressive. They’re more than capable of protecting your home from intruders and other problems! Be sure to consider purchasing a great system for your home.
