Motion Questions

Just wondering, can an outside ceiling fan that is being moved by the wind trigger a motion alert?  Also, can shadows cause Arlo to send an alert.  I've had several alerts recentlyand when I pull up the video I sometimes notice a fan on our porch slowly turning or, in one case there were shadows from local trees moving within the cameras viewing area.  If these can cause the alerts, I will reposition the camera so that the fan isn't in the field of view and reduce the sensitivity so the shadows won't (hopefully) be an issue.

The IR motion technology used in this system is sensitive to movement and reflection of light. Short answer is yes, what your describing can cause a motion alert

I watched Arlo for several days after the first incident and the unit never responded again because of shadows (if, in fact that was the cause).  Also, I actually turned on the outside ceiling fan to see if I could trigger any alerts and received no response.  So, I'm not sure if the alerts I received were actually caused by shadows and / or the fan movement and if not, then I'm a little loss concerning why several alerts were sent.

Depending on the exact scenario, don't forget that a bird or bug flying by close enough could set it off.
