The doors are from the perspective of the sensor switch left (1m), right (2m) and on the wall behind the sensor switch (15cm). At the same time going from the intermediate level a staircase upwards, ie people who come down from the upper floor, should be recorded (approx 4-5m).

That he should turn left, right, front, back, grasp the top and bottom, with the removal of close, 15cm goes to 5-6m. Conventional motion detectors have a poor detection range and can usually only detect lateral movement, so I decided for this RF sensor switch. My needs were well met. Some little "flaw": in the near door, that is right next to the switch, it also detects movement in the room already about 30cm in front of the door. However, this is for me a real problem.
