Surveillance camera on Saturday

Hello,
Question in the same context..
What about walking past a volume detector of an alarm system when the system is off?
System off = detector works and alerts but the system will not activate an alarm because it is in the 'ready' state. The detector is wireless and can only transmit without an input option and therefore cannot be turned off through the system but only by removing the battery.

What's the difference? Same.

I'll just clarify the question.
It's that the detector works and transmits every time you walk past it, but the alarm system doesn't respond to the transmission.
This is a detector installed in my house and I can, in principle, cover the detectors/remove the battery before every Shabbat.
The only difference is that I have the option to solve the problem. The question is whether this hassle is necessary.
Thank you

If the detector wakes up but doesn't transmit anything, I see no reason to worry. In my opinion, there is no prohibition in this. Rabbi Rabinowitz innovated that when you don't see direct results for an action, there is no prohibition (regarding a card that opens a hotel door on Shabbat), and there it is when there are results (the door opens) but you don't see the consequences of passing the card. This is an innovation that I'm not sure I agree with. But here there are no results at all (and not just that you don't see them) and therefore I see no need to be stricter.

In my opinion, you should only turn on the detector on days you're not home. Is that clear?
