Fixing this problem is as simple as upgrading the firmware of the product, but the old product usually has no new firmware. Usually the old DVR / NVR has a back door, users can connect to the system through Telnet and reset the password. Hackers usually use this method to obtain DVR / NVR management rights. The DVR management password can be reset, but you need to log in to the system menu to change the password after entering the menu. Many users think that removing the CMOS button battery on the DVR / NVR can reset the DVR / NVR recorder, so that you can log in with the original password.
