home automation light control
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. Once the power flips back on, the backup battery system will automatically recharge. The sensors, or switches, are the second part of the security system.
