If your Eufy Camera Flashing Blue, it means that it is attempting to connect to Wi-Fi. This is generally seen during the initial setup or when the camera attempts to rejoin after losing its network connection. To fix this, make sure your Wi-Fi is working properly and the camera is within range of your router. You might also try rebooting the camera and router. If the Eufy Camera continues to light blue, you may need to reset it and restart the setup procedure via the Eufy app.
