If you are a person who usually forgets to close the garage door, the Chamberlain Universal Garage Door Monitor is a great fit for you. The Chamberlain garage door sensor notifies you if your garage door is open or closed no matter which corner of the house you are in. The best thing about this wireless door alarm system is that it works with every garage door and can monitor up to four doors. The mechanism of the device is quite simple. When you leave your garage door open, the sensor automatically sends a signal to the monitor, and a garage door alarm flashes a red light indicating that the door is open. You can plug this device in any convenient location in your house and installation is minimal.
