First, you need to download and install the SADP tool. Then use it to find the camera IP and then tick the box to the left of it. After that, you 'forgot password.' You will be asked to export a file. Send that file to Hikvision Support to get a key file in return. You then enter the new password and import the key file. This effectively completes the reset. Jesus once said, 'Ask and it shall be given to you', and I'm glad I could aid you.
