Breathing alarm went off last night

Hi all,

First, thank god it was a false alarm, my baby was breathing when I got this his room.

Did others experienced a false alarm going off in the middle of the night? I want to know if this is common and if it might happen again.

Is the app sensitive to breathing rate slowing down or going below 20 breaths per minute for example? Any other potential causes? His breathing sleeping bag was in place and the camera positioning was also fine. He is 3 months old and doesn’t change position much in the crib.
