A Burglar alarm is a system designed to detect intrusion – unauthorized entry – into a building or other area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders. Security alarms in residential areas show a correlation with decreased theft. Car alarms likewise help protect vehicles and their contents. Prisons also use security systems for the control of inmates. Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance (CCTV) systems to automatically record the activities of intruders and may interface to access control systems for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multiarea systems with computer monitoring and control. It may even include a two-way voice which allows communication between the panel and Monitoring station.

4. Procedure
The IR transmitter or IR LED is connected to a current
limiting resistor of 150Ω and connected to supply. It is
placed at the maximum possible range from photo diode.
The cathode of the photo diode is connected to supply
while anode is connected to 10KΩ resistor. Other end of
the resistor is connected to ground. The anode terminal of
the photo diode is also connected to pin 5 of LM358 op
amp, which is the non-inverting terminal.
Wiper of the 10KΩ POT is connected to the inverting
terminal i.e. pin 6 of LM358 while the other two terminals
of the POT are connected to Vcc and ground.
Pins 8 and 4 of LM358 are supply pins. They are connected
to Vcc and ground respectively.
The output of the op amp is taken at pin 7. One terminal of
the buzzer is connected to pin 7 of LM358 while the other
terminal is connected to Vcc.

6. Burglar alarm system nowadays can also be used for
multiple purposes as well. These other functions include,
fire, safety alarms, as well as intrusion. These can also be
used simultaneously as well.
Today, people are very concerned about their own safety. A
lot of theft crimes are now committed because of extreme
causes, and it could happen to almost anybody. That is why
having a burglar alarm system is a recommended solution as
well as investment to prevent theft in your home or office.
