What if Zhongke Centrino hard disk video recorder forgets the password?

The Xiang Li brothers above are right. You can call Dahua customer service and ask them to provide the super user and password, or restore the factory settings, check the factory reset button on the back of the hard disk (or open its shell plate), if not, please call customer service and learn how to restore the factory reset. Before our company's products, there is a way to restore the factory settings, that is, through the rs232 port, the port is short-circuited for two feet and 30 seconds. Different companies have different products, please operate safely according to the company's customer service methods.
