If my Hikvision DVR (iDS-7204HQHI-M1 / S) is connected to the router via a LAN cable, I can manually add EzViz WiFi cameras to the DVR. However, if the DVR is connected to the router via WiFi, I cannot add the WiFi cameras. The DVR reports "network abnormal". The camera is not reachable. My WiFi allows communication between devices (no client isolation), and WiFi and LAN devices are on the same subnet. I can access the WiFi camera's stream from my phone.
What could be causing this issue?
