Until 20/09/2024, both my cameras were recording normally as per the schedule.  They're set to record movement between 07:00 and 19:00 Monday to Friday only.  Come Monday morning, 23/09/2024, neither camera is now recording normally.  One of them, which was fully charged on the Friday, had lost almost 75% of its charge by Monday morning - even though it shouldn't have been recording any activations (no recordings were showing on the app for that period).  Both cameras are fixed to the outside wall of our house (one c3 metres, the other c4 metres high) and both have a Tapo A201 solar panel attached.  Both cameras are set to record vehicles and motion, with a wake-up sensitivity of 10.  No setting for either camera were changed by me that might explain this issue.

What could have caused this, and what can be done to fix it.

I purchased the cameras and solar panels from Tapo through Amazon in July 2024.
