Straightforward burglar alarm system contains an electric circuit connected into an entryway, where a switch can be located. It opens or closes the circuit of the system and notices acts of intrusion such as opening a window or door. This kind of alarm is assembled into the entrance. The burglar alarm is classified into two major categories. One is the open-circuit system where the circuit is closed and electricity flows when the door is opened thus when there is completion of the circuit it triggers the alarm. Secondly, the other type is a closed-circuit system, wherein the circuit is closed when the door is closed. The circuit opens when someone opens the door, thus triggering an alarm.
Certain burglar alarms & CCTV systems have sensors attached to a main unit that drives out a signal upon recognizing any intrusion, fire or panic. Signals are normally sent in the form of loud noise. Modern-day burglar alarms send signals to the Internet or via telephone lines. Then the owner is alerted whenever a possible interference is identified. Usually, sophisticated alarm systems send an programmed e-mail or phone call to inform a person of any suspicious activity at home.
