Secvest 2way bewegungsmeleder detection pattern

[Wersch]

Hi nichtbeimir

this sounds really strange. Do you have the problem already described abus? What did they say to that?
In my opinion with the energy saving mode, the problem has nothing to do.
I find that rather than a non-small risk
please post all the answers you get to
Thank you

As told in another post, I returned a PIR detector that was way too undersensitive. Now I have a new one but I find its behaviour very intriguing too. It is placed in the entrance of the apartment and can "see" through the open door of the living room. What happens is if you are in the entrance you are always detected. However, if you are in the portion of the living room (only 1 or 2 meters farther, not more!) that is visible to the PIR, the Bewegungsmelder seems to detect me only when it has not detected anything for some time. And I am not talking here about the 1min or 3min freeze that you can set with the jumper. No, I mean, if I wake up in the middle of the night, the detector "sees" me in the living room. But, if I have just passed 10 times in the entrance, then wait 5 minutes in an invisible part and walk again in the detection area of the living room, then nothing happens. It is as though it was adjusting its sensitivity to the movements recorded in the recent past.

I am just wondering if this is normal or if this detector is just plain unreliable. In any case I don't find this pattern so desirable. For the same price I would probably be better served with a XEVOX but than means drilling a few nice holes...

If you are a SECVECT user, what is your experience with this Bewegungsmelder?
