I have 2 HIK Vision cameras I would like to restore to the default password and username 12345 and admin. I want to use them on a Cobra NVR from Harbor Freight. I have the configuration files downloaded from the cameras by using http://<camera_IP_address>/System/configurationFile?auth=YWRtaW46MTEK. I have tried looking at the files to extract the password but find nothing of use. Does anybody know what tool to use to extract the User name and password, and willing to share that information. Alternately would someone with that knowledge please extract that information for me. I have the 4 port HIKVision nvr the cameras came with and have the password to it, but I have fumble fingered the passwords to the cameras. I notice one of the files is much larger than the other, but don't know why that is.
