yesterday received, unpacked and fnktioniert properly. Picture and sound just great. I live in EFH itself from the floor to the basement still welcome and really have many confounding factors, such as plenty of Funiereisen in the walls, metal grilles and railings in the stairwell. A small drawback of this top product but in fact the camera can not adjust the angle ° 180. But is not so bad, since it is sufficient for our needs. Absolute recommendation!
