Will outside motion sensor/detector floodlights be effective from a second floor mounting?

Simple question here, but I can't seem to find a simple answer anywhere online. I'm considering changing my regular outside floodlights to the motion sensor/detector type. We live in a two story house, and the one covering the backyard is mounted next to a second story window. This is actually quite high -- probably 20 feet or more. Will a motion sensor work effectively from this height? Or do I need to consider a new receptacle placed lower down?Will outside motion sensor/detector floodlights be effective from a second floor mounting?Yes, it will work. The only problem will be if you have any animals roaming your yard. Most motion detectors suggest an angle that allows for dogs and cats to roam without turning on the lights. From a high point, you will not be able to do this. It will also narrow the field of motion that is covered.Will outside motion sensor/detector floodlights be effective from a second floor mounting?If I were you, I would get a motion detector that is separate from the light fixture. Mount the sensor down low so you can set it up and make changes if you like later.Will outside motion sensor/detector floodlights be effective from a second floor mounting?to add to your answers. you can also purchase a more expensive light that has a sensitivity sensor on it that you can adjust. hope this helpsWill outside motion sensor/detector floodlights be effective from a second floor mounting?
