Motion sensor in household with large dog

Sorry, this may have been answered, I am new here and can't figure out how to search this forum.

Any way, just installed simplisafe system last week. motion alarm was triggered twice. I figured it was in the room where our roommate, 180lb St.Bernard likes to nap.
It was not triggered by motion sensor or camera in kitchen he does walk there when he wakes up. Is there an adjustment to decentisize sensor?

Thanks in advance.

Hi @relevart123_CWZNKE, Yes,

Hi @relevart123_CWZNKE,

Yes, there is a sensitivity switch on the rear side of the motion detector. It's a small black switch directly above the battery. To lower the sensitivity on that motion detector, just switch it to the L on the left. For more information on how our Motion Sensors work with pets, visit this page in our Help Center.
