For whatever reason, I don't think the motion detectors work as they should. I have an ActiveEye inside the house controlling a transceiver to turn on/off a lamp when someone goes into the room. At times, I literally have to jump up and down in front of the sensor to get the light to turn on. Other times, when I'm hoping it wouldn't turn on (when i'm in another room, for example), it picks up my motion and the light goes on. Then, I have to literally send it an off command from ActiveHome to turn off. I've tried all sorts of debugging, but can't get it to be 100% reliable.. a bug? a feature? who knows!
