How home security system work?

The simple concept behind a home security system is securing the entry points to the property with sensors that can connect with a command center or control panel installed in the home at a convenient location. While the sensors are installed in the doors and windows, the open spaces are usually secured with motion sensors.
Control panel is meant to arm or disarm the security systems and also communicate with all the different components of the system. While there is a security breach, the alarm is sounded and communication is sent to the monitoring company.

  • Sensors installed on doors and windows have two parts with one installed on the door frame and the other installed in the door with both of them touching each other and establishing a circuit when the door is in closed position. While opening the door, this circuit is broken and the system deems it as a security breach. Now the high decibel alarm is sounded and the alarm monitoring company is notified.


  • The motion sensors protect a given space by deeming it as an invisible zone. If there is any breach they sound the alarm. This feature is applied to rooms containing valuables.


  • Surveillance cameras are meant to serve different purposes as part of a security system. They are usually depended on for monitoring the areas of the property that are difficult to see. The aspects covered usually include the garages, workshops, garage, front doors, entry points and barns.


  • High decibel alarms notify the homeowners regarding the intrusion, alerts the neighborhood and sends the burglars running in panic.


  • The yard signs and window stickers also play a crucial role in home security. When they are placed in a way noticed, they send a signal to the burglars that your property is under professional protection and it is not a wise target to attempt breaking it.
