Now you won't have to go downstairs or outside to see if you accidentally left the garage door open. With the LiftMaster® Garage Door Monitor, you can check and close the garage door from any room in the house. MyQ™ enabled technology allows you to monitor and close up to four garage doors from any room in the house. Green and red LEDs indicate whether the garage door is open or closed and the volume-controlled audible alert lets you know when the garage door is being opened.
