If your camera is the 1st generation:
Use a thin needle or pin to reset the camera. The reset button is located on the upper left side of the QR code on the back side of the camera. Please hold down the reset button until the yellow light turns on. The reset is successful when the yellow light is on or you hear the voice “Reset is successful”.
If your camera is the 2nd generation:
You need to remove the back cover off your camera and then you will see the white round reset button. Use a pin to push it until the yellow light is on and you hear “Reset is successful”.
