Hi, 
You can try the following steps and check whether the camera will work.

  1. Turn on the camera, wait for two minutes, and press and hold the reset button on the camera for 10 seconds to perform a factory reset. Then, check the LED status on the camera.

  2. If the LED is flashing red and green, enable a hotspot Wi-Fi on your phone, open the Tapo app on a different phone, try to configure the camera, connect it to the hotspot Wi-Fi, and then check if you can set it up successfully.

  3. After you set up the camera, you can test if the camera is working fine. Then try updating the firmware via the Tapo app.

  4. After that, try factory resetting the camera again and connecting it to the home Wi-Fi, and check if it works fine.
