Title: Doesn't work
Review: We bought two of these. Ours never worked right. We had to keep moving the monitor closer to the garage even though the distance was listed to work correctly. It just keeps blinking green and red. It will stay red sometimes if the door is open and the weather is good. We placed it by the back door and that didn't work either. We can just look outside so this is useless. The second one is in our daughter & son-in-law's garage which is attached to their house. Theirs worked for a little longer but now is malfunctioning too.
