I have six Dahua 4MP IP cameras and a Dahua NVR with 8 channels ePOE and 8 channels POE. The cameras are wired directly to the NVR - no WiFi. Is there a way to record the image from each IP camera to two NVRs without using WiFi? When I had the same setup with HDCVI and DVR Dahua products, I had the cameras attached to a distributor which then allowed two DVRs to record each camera image. Thanks!
