Hello, I'm inquiring for assistance. Currently, I'm using a vstarcam N8209p NVR connected to 8 cameras of different brands. Two of these cameras are newly purchased, the tapo c320w and c510w. I'm experiencing a time synchronization issue. I've tried adjusting the settings in the camera, and the time seems to be corrected, but after a while, it reverts to the incorrect time, particularly when connected to the NVR. (I've tried turning off the NVR, and the time stays correct.) I've attempted to resolve this by:

• Disabling the NVR's sync time feature, but the issue persists.
• Trying to ping pool[dot]ntp[dot]org, resulting in timeouts.
• Removing NTP servers from the list and using time[dot]window[dot]com, which I can ping, but the problem remains the same.

Notably, cameras like the c200 and c210 are working fine with no time synchronization issues. If anyone knows how to fix the problem I'm experiencing with the tapo c320w and c510w cameras, I would greatly appreciate your help.

Thank you for your assistance!
