When deciding which type of security system to install, here are some of the basics that you should be looking at. These three components alone can range from minimalistic to advanced. The control unit is the main operating panel for your home security system. This
unit receives the signals from the sensors placed around your home, and triggers the alarms or contacts the home security center to notify them of any trouble whenever appropriate. The control unit may be powered
by electricity that runs in your home, or by battery power. Some systems are set up so that if the power in your house goes out, a battery backup will kick in and run the control unit until power is restored.
