Hi,
If you have changed your router's Wi-Fi name and password and now need to reconfigure the camera to control it in the Tapo app, please try the following steps.

  1. After powering on a camera, wait for two minutes.

  2. Press and hold the reset button on the camera for 10 seconds to factory reset it. Then, the camera will have a flashing red and green light.

  3. You can refer to the following instructions to set up your camera to connect it to the new Wi-Fi network. If the camera is configured successfully, you can repeat the steps to configure another camera.
