After cameras are properly configured on the configuration page, the first camera can be added using the configuration tool, but the second camera cannot be added.
Log in to the NVR Controller.
Both the default user name and password are admin.
Click the NVR management tab and choose Service Surveillance> > Running Mode.
Under Peripheral Equipment, click Add.
For the parameter description, see NVR Controller Help.
Check the compatibility list. The model of the camera that cannot be added is not in the compatibility list. The camera must be connected using the NSS method instead of the PUG method.
