C51S STOPPING IN A LITTLE TIME

C51S STOPS WORKING IN A LITTLE TIME.
DISCONNECTED FROM THE CURRENT AND CONNECTED AND WORKS, BUT IN A LITTLE TIME IT STOPS WORKING.
HOW CAN I RESET IT?

Hi, Sir/Madam,
Thanks for your messge, the camera's reset button near to the power button, it's a black button,
Power on camera, then long press it for about 5-10 minutes, it will reset successfully after reboot.
