On the test, I reset the password on the DVR DS-7204HQHI-SH with the firmware version 3.1.3.
Since to him probably some schoolboy picked up a password, changed it and wrote mucks in the names of the cameras :)
The first step is to download the SADP utility from the official site
Run the utility, connect the device to the same network as the computer or a direct cable to the computer.
The utility displays the connected device, as well as its serial number, in my case:
We copy this serial number, removing the model of the device in the beginning, in my case it turned out:
Open the security key generator, enter this serial number, specify the date that is set on the device and generate the code.
Open SADP again, select the connected device in the list, click on the “Forgot Password” on the right, enter the code, then enter the new password in the “Admin Password” line.
Now you can enter under the admin login and the specified password in the web interface of the device.
If the device was hacked, it is desirable to immediately reset the settings and update the firmware to the latest.
Code generators can be found on the Internet, for example, here are a couple of online generators:
Also, the code can be requested from HikVision technical support or the store in which the device was purchased.
