An security or burglar alarm is a collection of electronic devices designed to work to gether to detect any unauthorised entry into a premise. It will then notify the owner or the law enforcers of the breach.

In summary, they basically perform the these 3 functions:

  • Detect
  • Decide
  • Alert

Detection is handled typically by sensors such:

  • Door/Window sensors
  • Infra Red Sensors (Usually Passive)
  • Manually activated Panic Button

The functions of these sensors are primarily to detect any irregularities within a guarded zone and send a signal back to the control panel to decide on the next course of action.

The control panel, which is basically the “brain” of the whole system will then decide on the actions corresponding to signals it receives. Based on it’s pre-installed features and post-installation programming, the alerts may include (but not limited to) the following:

  • Sound of the siren
    • To alert the home owner and the neighbourhood
    • To alert the law enforcers
    • To deter the criminal from continuing his crime
  • Turn on the spot lights
  • Dial up a telephone number
    • To alert the owner who may be away from home to decide on the follow up actions. Most established brands will have this feature built into their systems.
  • Dial up to a security monitoring service provider
    • This is a subscription based service which a security company will respond on your behalf once they receive any notification from your device
