Eufy cam 2c turns on at night

I have an eufy cam 2c at my front door, I also have automation for it to be turned on for a video if motion detected. While on home settings (no notification or alarm should be on, everything is turned off) it happened that the camera was turned on (at night you can see the night vision lights) while reacting to us passing.

Does this mean it’s a hacker?
That happened only twice so far while passing through the camera (does not seem to happen spontaneously)
