I am pleased with the motion eigenlich. Erhat a large detection range and the operability of the adjustment control is pulling through the down of the sensor head is no problem. In my application, a portion of the surveillance area is slightly darker than the surrounding area and thus it turns something füher than intended, which can not be compensated by the Eistellregler for brightness. But this is not a flaw, because with uniform illumination with natural light, there is probably no switching problems.
