@Ethan-TP The subnetwork being run by the 108E should not be accessible via anybody connected to a wireless access point. But the PC on that subnetwork should be able to pull up IP's across the entire network in order to perform configurations and updates. Also, traffic on the wireless AP's should never be so high that we can't maintain a livestream via devices on the 108E. I'm mostly worried about making sure that the settings on that router are correct for what I want to accomplish. Also, the 108E is in a different room from the main switch, and I want it there in case we add additional equipment such as another PTZ camera.

I also had another person recommending a few changes to our configuration so while we already have the 108E, we're proposing that we purchase an Omada 20-port managed switch with PoE+, Omada 200 controller, and three Omada AP's, if that changes anything. He's assuring me that we can segment off the wireless AP's. The above diagram still basically reflects how I imagine everything will be connected.
