Yes @Foremost_Farms , @BrechtSchamp is correct that all of your Camera Admins will have access to all of the video walls that you configure for a given network. On the Network Wide > Administration page for a given camera network, you can create all of your camera-only admins, and control which cameras they can access (by individual cameras or by tags) and if they can only view live footage, or if they can view and/or export historical footage. But that's all independent of the video walls that are configured. All camera admins will have access to all video walls for that network.
Hope that helps, or let me know if I misunderstood your question.
