Duhua nvr

[Daire Tucker]

Hi,

Im using a duhua epoe nvr. I have a cat5 cable from my epoe port 1 on the duhua nvr going to a switch 300m away with 4 more ip cameras plugged in. Can epoe port on the back of my nvr be used for more then 1 i.p camera?

No, it does not work like that. A PoE switch can't power another switch and then power more cameras. Generally 1 port - 1 camera.

Thanks jmcu i guessed that much.

Have you any ideas to resolve my issue?

What ePOE NVR do you have? It must have more than 1 port... ?

You can use a poe port on the back of a NVR to another POE switch and let the second poe switch power your cams. You might have to manually add them but I have done that a few times. Make sure the cams are on the same subnet as your switch in the NVR.

But the cable distance from my nvr to the switch is 300metres?

Not the most Ideal situation but On the longer runs I have used a Midspan switch between the runs.

Do you mean cut the cable half way and fit a switch?

Not sure e-poe will perform with a cat 5 cable to begin with. I have not deployed any E-PoE runs yet but have gotten 400' no issue with decent cat6 cable. You might have to scrub your idea and get some cat 6 in there first.

Correct. But again If you only have cat 5 I think you are not going to fare well, should have a minimum of 5e in there for your runs.

We unfortunately took the job over there was an existing system of analogue cameras. So the wiring was already in place cant redo whats already there. Reason for the forum
