Dahua 4208 8p 4ks2 camera stays red

[DWinters1979]

Hi guys,

got an issue with installing a camera to the NVR 4208 with built in POE.
I just removed a Dahua cam and put it in another place and installed it. 2 new RJ45 connectors en plugged it in the NVR.

The NVR sees the cam but the little bulb stays red. Rebooted the thing a few times, no result.
Measured the cable and all the 8 wires are fine on both sites.

Then put the RJ 45 plug in port 8 and the cam comes online. So the cam is working correctly.
But when i placed it back on it's original place (port 4) it stays red.

What am i doing wrong???

Try rebooting the NVR with it plugged in to the original port

Delete it from the registration page before the reboot and any copies of it with the same 10.1.1.x address

assume you didn’t change the password on it and its same as the NVR?

Hi, thanks for the reply.
Already did that a few times.

I’ve swapped ports successfully so it can be done. The ports tend to be assigned the same IP regardless of what’s plugged into them so often an IP conflict. Usually deleting that camera, then plugging back in and waiting does the trick.

Red indicator typically means either
A) camera has password set the NVR doesn’t recognize- ie different than the NVR , in which case use the edit icon (pencil) to tell the NVR the correct pass that the camera is using
Or
B) due to manually adding the camera (don’t) or a duplicate entry, unplug cam, delete any entry referencing it (top and bottom pane on Reg page) and plugging back in the cam and allow the NVR to auto discover it. I’ve seen this take as little as 30 seconds and as long as 30 minutes.

Can you show a pic of the registration screen with the camera plugged in?

Assumptions

• camera password has not been altered and is same as the nvr
• not manually adding camera, allowing self discovery
• camera is set to dhcp

Thanks for your input. Tonight I’m gonna try it again.

There may be some info here that can help

***PSA for those with a New DAHUA NVR with Built-in PoE switch

IF you have a Dahua NVR with built-in PoE switch... DO NOT follow instructions telling you to use the config tool or switch the IP of your cameras or initialize anything..! With NVR's typically with a -P designation (Built-n PoE switch - example: 4208-8P-4KS2) none of that is required and it...

Great i’ll try that.

I fixed the problem. It was a wiring problem, cat 7 cable on a RJ45 jacket, asking for problems.
I also followed the manual for automatic let the NVR put the cam on the right place and port, but that did not work.
It took too much time waiting for that to happen.

Last time when adding a camera on my NVR also problems with adding them to the NVR. And 37777 instead of port 1...4...8

Yes, as the PSA mentions, manually adding them will give you the 37777 port and you won’t be able to connect via the IE icon

So can i fix it with unplugging the cables and then plug them in and just wait for the nvr to assign them?

 

[bigredfish]

Yes As long as you haven’t changed the password on the camera. By default, it will assume the same pass as the NVR and you should get a green indicator and a port of 1,2,3 etc. with an IP of 65,65,67 etc

Do make sure and delete the cameras you unplug from the registration screen (top and bottom panes) after unplugging them and before plugging back in
