Pro 3 keep sending notifications at night

[Garebear56]

I have two Pro 3 Cameras one facing south across the driveway and one facing north towards the house. They have been working fine until about 3 weeks ago. When it gets dark at night, both cameras start sending motion alerts non stop. When one cameras light clicks it alerts the other and they go back and forth. It does not do it in the daytime.

Sounds like pixel detection flip flopping between the cameras. Added external power to the cameras recently?

How close together are they? Can you separate them further?

They are both wireless and I have them plugged in right now. Yesterday I removed them from the base station then added them back in and now seem to be ok for at least one night but will see
