It’s a question every homeowner asks before going to sleep at night - are all the doors closed and locked? With a detached garage that opens to an alleyway, the last thing I want is for my garage door to be open for an evening. The Universal Garage Door Monitor was the perfect solution. The unit took only a few minutes to install. The monitor is inside the house, approximately 40-50 feet away from the sensor and it works perfectly. The price is certainly reasonable for the everyday assurance that the door is closed.

The Universal Garage Door Monitor works with any overhead garage door. Mount the sensor to the back of your garage door with the included Velcro strip. When the door opens, the sensor moves into the horizontal position and sends a signal to the monitor that the door is open. The monitor then provides simple, visual cues to indicate your garage door's status: When the light flashes red, the door is open; when the green light is on, the door is closed.
