I have 2 Tapo C200 cameras set up for continuous recording and to send motion detection notifications.

They have been working fine for about 10 months, but this morning when checking the notifications, I find that I am getting 4 notifications for each movement detection. (see screenshot)

This is happening on both cameras, and 3 different phones running the Tapo app. I have tried restarting both cameras and re-formatting the SD cards, but still have the problem.

Any ideas ?
