Please first power on the camera, and then find the reset button of the camera, and press and hold for 5 seconds to hear the voice message indicating that the camera is reset successfully. The camera will return to the initial state. The password for camera connection is 888888, and then use O-KAM or Eye4 APP to add the camera again. If you need more help, please send email to support3@vstarcam.com, thank you, I wish you a happy life, a wide range of money!
