We had green lit a surveillance system on the condition that it'd be configurable to the spec that our security team laid out. Camera endpoints would be on an internal subnet - 10.1.x.x The NVR would be on our DMZ - 10.7.x.x We've laid out routes for the 10.1 gateway to go to the 10.7 network. Now our vendor has disclosed that the NVR and cameras cannot communicate if they're on separate subnets, even if we've setup routes on our end. This is after they drilled holes, ran cable and mounted cameras through the campus. Anyone run into this type of issue?
