ho lives on the 5th floor, from time to time due to mistakenly remote control led to open the garage door. Is there any way you can upstairs know downstairs garage door off?
Install a camera bar, do not worry to open the camera to check it.
In the bottom of the garage door installed a limit switch, connected to the fifth floor of a special light (red, flashing lights and the like), as long as the door to leave the ground automatically lit lights chant. In fact, as long as the remote control of the wire break caused by insufficient signal transmission, there is no remote control in the fifth floor garage door down the situation!
