Hi,
We need more information to analyze the issue, and please help confirm the following info.
1. Please describe the detailed problem phenomenon when the camera is not working, such as LED flashing red, can't watch the live view page, or other phenomenon.
2. What's the model number, capacity, and format of the SD card you insert into the camera?
3. Have you enabled continuous recording on the Tapo C210? What detection types have you enabled, such as motion, person, etc.?
4. How do you test if the camera is hot? And what area on the camera are you touching to test if it's hot? How long does the camera become hot after you insert the SD card?
Best Regards
