You probably already checked this but:
- Make sure you have no filters in the Event tab.
- On the outdoor cam, make sure it is mounted right side up. Some have mounted it upside down because of the Magnet Base and how they installed it. The Top of the Camera is also able to connect to the magnet as well.
- Make sure the PIR area is where you want to be notified of. This can be found on the Detection Setting Screen at the bottom.
Here is a post I provided in the past which includes an image of where the PIR is.
But as I said, above, you probably already know this.
