The most common type of burglar alarm is the closed-circuit system. This type cuts off the electrical current surrounding the perimeter of the home to alert authorities of an unauthorized intrusion. This type of system is susceptible to being tripped by burglars because they are unaware of the circuit. On the other hand, an open-circuit system flows when a specific trigger is triggered, and this causes the alarm to be activated. Depending on the type of system you choose, there are several options available to protect the perimeter of your site.

A typical burglar alarm consists of an electrical circuit that is built into the entry way. Electricity flows when there is a path between points with opposite charges. A closed circuit exists when a door is shut. An open circuit prevents the flow of electricity and will trigger an alarm. This system also uses a motion sensor to detect intruders, which will help deter them from trying to break in. These systems are typically very inexpensive and will allow you to protect more than one location at once.

Burglar alarms come in a variety of configurations, but they all work with a system of door, window, and motion sensors. These sensors work with a control panel to detect breaches of your home or business and alert the owner or authorities. Basic burglar alarm systems monitor the perimeter of a building and create an electric circuit. When the door is open, the electricity does not flow and the alarm will go off. A monitored system can monitor more than one location at once.
