Security Systems have been installed in homes and businesses for years, At Total Home Automation we donít install plain old security systems. The systems that we install are the brains of the Smart Home. The same motion sensors that trigger a burglary alarm are used to turn on lights or trigger a surveillance camera for recording. Window contacts are not only for theft detection, they also send status back to the controller to turn your air conditioning off if a window is opened. You can actually control your lights from your keypad.
