Hello,

Welcome to the community, and thank you for taking the time to share such a detailed comparison between your cameras.

 

To help narrow down the cause, we kindly suggest the following basic checks and tests:

• Check signal strength: Please verify the Wi‑Fi signal quality of the C250 in the Tapo app, including its RSSI value, and ensure it remains stable during live view.
• Swap camera positions: If possible, try exchanging the physical locations of the C250 and C100 to see whether the delay follows the camera or the location.
• Isolate the live stream: Temporarily close or stop the live view of the C100 and observe the C250 alone to check whether the delay improves.
• Test on the local network: Please confirm whether the same delay occurs when viewing the C250 while your mobile device is connected to the same local network (LAN) as the camera.
• Network latency check: If you are familiar with basic network testing, you may also try pinging the C250’s local IP address to see whether there is noticeable network latency or packet loss: How to use the Ping command

 

If the issue persists after these checks, please let us know your test results, along with the app version you are using.

 

Best Regards
