The most basic alarm systems have these sensors fitted in the frames of windows and doors so that if they are opened, the circuit is broken and the alarm is triggered. Some are installed in a way that allows them to detect if someone tries to break in through a window by shattering the glass or removing one of the panes. Others may detect motion inside or outside of the home. The third essential part of a home security system is the alarm. There are many different options as far as which type of alarm you can have installed. Some alarms are set to trigger a loud siren in order to deter potential burglars after they attempt to get in to your home.
