Imagine you are out and someone breaks into your home and makes away with all the valuables. Even the thought that this might happen may keep you from enjoying yourself. To avoid such a situation, you need to get a burglar alarm.
How does it work?
A burglar alarm is an electronic device that is designed to go off if someone tries to break in and thus alert the homeowner or others of the danger. If someone tries to break open the lock on a door or window, the burglar alarm will sense the motion or pressure and it will sound a loud alarm. This is done with the help of infrared waves. The response device uses low bandwidth RF signals to connect to the sensors. You may also find other types of security alarms.
Burglar alarms come in two main types, wireless and wired. Usually people use wireless alarms, as they are easy to set up and prove economical. These systems are available in many types; they incorporate small devices and also more complex ones with monitoring facilities.
Burglar alarms are classified into two kinds depending on the application, for home use and ones that can be used in industry – the latter being more sophisticated.
You can also integrate cameras into the alarm system which can record images or videos. These recordings can be sent to a centre which can retrieve the images using proprietary software. You can even view these recordings at a remote location. Such information may also be needed by the police to look for evidence.
