Everytime I walk into the garage, I noticed the flood lights on the mirror are on. It seems to detect the key fob is near and turn them on? Is this the case? I haven't done any extensive testing with/without the key fob or tried to determine if the lights are warm (indicating it's always on). I do have a camera in my garage, but I'll need to wait for nightfall to determine if they're really on or off and how close the keyfob must be.
