Did you use the Home/Away mode feature? It allows users to configure two sets of settings for multiple cameras, including the notification feature. How to edit Home/Away Mode of my cameras

You may want to check with anyone who has access to your account to see if they’ve used this feature. Also verify whether the app is logged in on other mobile devices, as settings could have been changed from there.

Considering the camera offline issue you reported in another post, I can’t help but think the two problems might somehow be related and could even share the same root cause. I’d recommend reaching out to our support team directly for a deeper investigation. Contact Technical Support

By the way, where is your camera footage stored? Does each camera have its own SD card, or is everything saved to a Tapo hub (which one?)?
