Hello,
Welcome to the community, and thank you for reaching out. We understand how concerning it is to see your cameras go offline while you’re away from home, especially when you need to monitor the situation remotely.
To begin with, we’d like to clarify a few points so we can better understand the situation:
1.Do all of your Tapo devices (the C210P2 cameras and the D210 doorbell) currently show as offline in the Tapo app?
2.Is this an issue that started today/recently, or have you experienced similar connectivity problems before?
Are other internet‑connected devices at home (such as phones, TVs, or routers) still working normally, to your knowledge?
3.If multiple Tapo devices went offline at the same time, this usually indicates an issue related to the home network or internet connection, rather than the cameras themselves. Since no one is physically present to reset the devices, the key focus should be on verifying the home network status.

We recommend checking the following, if possible
1.Confirm whether your home internet service is currently online (for example, by asking someone at home or checking your router remotely if supported).
2.If your router supports remote management, please check whether it has restarted, lost internet access, or changed settings.
3.If you are using a router + extender/repeater, please ensure both are still powered on and connected properly.
For more detailed guidance on this type of situation, please refer to the official troubleshooting steps here: Cannot view Tapo/Kasa Camera
If the problem persists, it may be necessary for you to contact us again once you return home, so we can continue troubleshooting with physical access to the network and devices.

Best Regards
