Model: Tapo C200  
Hardware Version: V3
Firmware Version: 1.3.0

Summary: The camera records videos with incorrect date/time stamp when WIFI is off.

 

Steps to reproduce:
1. Configure the camera to be on 24 hours a day and to record to the SD-Card when it detects a motion.
2. Configure the camera to restart once a day at 8:30am.
3. Set the WIFI availability from 6am to 12am (18 hours).
4. Trigger a motion event when WIFI is off (e.g. at 1am).

 

Expected result: The recorded video and the Tapo app show the correct date/time stamp of the motion event (e.g. 1am).

 

Actual result: The recorded video and the Tapo app show the date/time stamp of the time when WIFI was turned off (e.g. 12am).

 

Additional information: It assume that the camera tries to get the date/time from the NTP server when it records a video, but fails when WIFI is off. It should use its internal clock instead.

Hello, thank you for the post. 

 

Tapo camera is synchronized with time from NTP server indeed, when the camera is disconnected from the internet, the time can still run and calculate normally. Since it relies on the associated electronics in it to calculate the time when running locally, the error is inevitable. And the longer it runs locally the greater the margin of error.

 

What is the time difference between the local recorded video and the actual time when the Internet is disconnected? Can you share some pictures here?
