The motion detector is working properly as described. The key for me - except for the low price - were A) which is a corner installation possible, this is supplied with an adapter directly in the set, so the motion can be set not only on a flat wall, but also on the corner of a building and B) the load to be switched - for me it's more halogen lights that are controlled by a low voltage transformer 12V - not just about the motion, but can additionally be controlled externally with a switch. It gives me therefore possible either to make the motion off the lights in Abhämgigkeit from darkness / twilight, or such as at parties constantly to turn on a switch. Not all movement detectors to a switched voltage at the switching output.
I have still not forgiven all the stars, because the specified range of 12m is not reached. Otherwise great product, can recommend.
