Is this a HomeKit camera or are you using third party software? HomeKit allows for defining zones for activity detection (so you could exclude an area) and only sending activity during certain times. If you don’t use HomeKit, maybe your camera software has a similar setting.

That is how it works. Unwanted tracking notifications only trigger if separated from the owner for some time. It’s possible the paired iPhone was drained or had Bluetooth disabled which would cause the tracker to think it’s separated.
