I recently installed two Dahua cameras at my home, one Dahua IPC-HDBW4300E and one Dahua IPC-HFW4300S-V2. They are powered via POE from a NETGEAR ProSAFE FS108PNA.
The Dahua IPC-HFW4300S-V2 is run on about 30' of Cat5e and works flawlessly. The Dahua IPC-HDBW4300E is run on about 50' of Cat5e and works intermittently at best.
If I take the Dahua IPC-HDBW4300E down and run it on a shorter Cat5e ethernet cable it works flawlessly. This lead me to believe there may be signal loss in the Cat5e cable I had run so I ran a new Cat5e cable but I get the same intermittent results. So then I thought maybe it's power loss and I bought an AC adapter and ran power directly to the camera but it doesn't seem to make a difference either.
Both cameras are running 2.420.0004.0.R, build: 2014-11-03.
I am out of ideas. Any help would be greatly appreciated.
