I bought two of these alert systems. (I wanted a extra receiver for the other end of my house.) I tried the sensors out of both kits and neither will transmit further than 180 feet from the receiver. This is no where near the 1200 feet listed in the instructions. This distance is drastically cut down if I do not have the receiver in a window with direct line of sight. It defeats the whole purpose that I purchased this unit.
