I installed iVMS4200 client on my PC. I added to my remote NVR as a device using Hikconnect Cloud P2P. Everything works well. I created an Operator user locally in the iVMS application (not on the NVR) and I set the operator to have only "Live View" (function permission) to the cameras (as resources) nothing else. However the Operator account can still access the Maintenance and Management tab in iVMS and actually make modifications to the remote NVR via the configurations. Is there any way that I can totally disable the Maintenance and Management tab in iVMS 4200 for that operator account?
