I have various wyze cams and even though motion is going on my recordings generally stop @ 12-14 seconds.
Now I have not tried to experiment but, im considering putting a fan or something out in front of one to see if it records longer videos.
Do you assign your camera to the cam plus plan?
Since you are getting video over 12s it appears that your cams are assigned properly to Cam Plus, assuming you are not also experiencing a cooldown. I just took a look at my OG Cams assigned to Cam Plus. They are uploading full length video.
What is your sensitivity setting?
they vary. I will crank up the og camera tonight and see if it goes longer. Im having other issues with cameras not recording at all lately so I have zero inspiration to deal with crap that just stops working
