Chris I am not sure what the eagle eye is by X10 is this a motion sensor for lighting or for a home alarm system. IF it is for an alarm? Why would you want to put it out side. Any small house anamil like a Crockidial might trip it off. If it is for lighting thats another story. Next question why is it called a motion sensor when it is activated by heat. living in Flordia I can see you having a problem right now. I would have been a little weary in the first place buying some called a motion sensor that works off of heat. I may have bought a heat sensor that when Automated will turn on lights in a dark room. I can see that happening. But if you want my opionin I would have not stopped or even given X10 a second look. Next are you trying to use it for something it was not intended for? You might just want to box it up and send it back. It could just be defective too ya know.

Good luck
