You know the kind where the cameras are on their own DHCP subnet seperate from the viewing LAN. The firewall is already punched to give access to the NVR. Everything works fine, but...
you need to set some parameter that is not configurable thru the NVR on a particular camera.
You have a non-technical end-user who is capable of plugging and unplugging cat 5, and typing a command or two if directed, but not much more.
How would you get access to a camera without going on site?
