Dahua 3x PTZ dropped off router

cappedup · Feb 18, 2017

I've been using my Dahua x3 PTZ for a couple of years now and it's been great.
Couple of weeks ago I couldn't access it, I've discovered that it's dropped from my router. It used to show as connected through Ethernet, now nothing.

I've tried a reset of the router, reset of the Dahua, doesn't show up.

The camera is powered by PoE, and seems 'live'. The lens reacts to a bright light, so it's behaving like someone is home.

When I attempt a reset of the camera (hold reset button for a number of seconds) it doesnt fully power down and reboot, like I thought it would. The fan continues to whirr. Is this normal?

I'm a bit stuck. I've always been able to troubleshoot the camera myself, but I've never been able to not find it before.

Any ideas?

Pulled the camera down, swapped the ethernet cables either side of the PoE injector.

Just the Ethernet connection has disappeared from the router. Not really sure what to check next. Tried different Ethernet ports.

I use iDmss to access the camera, but that hasn't got anywhere to look.

Can anyone confirm what's should happen when I press and hold the reset button? This doesn't seem to actually do anything.

I have a red led on the upper PCB which stays solid.

The fan doesn't shut down, and the led stays solid when I try and reset.

The only way to get the camera to react, is if I physically move it around, then do a hard unplug. When plugged back in the PTZ will return to a preset 1st position.

What else can I try? This isn't possibly bricked is it? I've never tried a firmware install, it's always just been fine, with no intervention.

Any help, greatfully received.

try another PoE injector or using the external power lead.. its probably 12vdc but some ptz's are 24vac.. whats your model#?

reset button has to be held on bootup, then it just clears configs.. really doubt it'll do anything for this issue.

Model is W-IPSD3282D sticker on back says input - 12v:2a

The injector is TP-Link 48v.

Wish I knew where the power lead was....

It should have a 12v barrel plug on the pigtail..

cappedup · Feb 19, 2017

It's the adapter plug I can't find.... grr.

Just factory reset router. No change.

cappedup · Feb 19, 2017

I guess next thing is to try a new injector. Although this one seems to be doing everything it used to.

nayr · Feb 19, 2017

well your not getting a network link and thats sitting inbetween em.. so we needa rule that out as being a problem somehow.

cappedup · Feb 19, 2017

Yeah. Makes sense. Will report back. Thanks for the input.

cappedup · Feb 21, 2017

Injector ruled out.

New one out of the box, same deal.

Tried finding the camera at the IP address it should have.

I have another network I can try this camera and injector on. After that, I should try and connect another Ethernet device to this network, see if that device shows. Try and boil it down to camera Vs network hardware.

Any further advice most welcome.

take the injector and plug the camera directly into the GigE network card on a laptop or desktop and see if you can reach it after manually configuring your network to match what the camera should have.

Going to have to park this problem for a couple of weeks. Away with work now.

Thanks for the assistance. I'll crack it when I'm back.

cappedup · Apr 14, 2017

Back for a few days.

Wired as follows:

Laptop ------> injector ------> camera

What's the plan for manually accessing the camera? I'm not entirely sure what the ip address of the camera was. And I'm sure I've factory reset it anyway.

In a few years time I'm certain these things will be actually plug and play. Instead of plug, pull your hair out, then play.

Many thanks for any help.

I believe I've set my pc Ethernet card to have the static ip of the camera. Pic attached.

Camera plugged into Ethernet port via injector.

Reset camera by holding reset button while booting.

Navigate browser to 192.168.1.108, assumed default ip of camera.

Nothing.

I'm wide open to ideas here.

Nope. Can't have the same IP as the camera will have when reset. Use anything other than 108. Set the preferred DNS to 192.168.1.1 as well

Here's what I've learned about resetting to factory. Hold the reset button for 60 full seconds after applying power. A few seconds will NOT do it. Resetting an HDBW5231R-Z over the weekend, when I held it shorter than a full minute, the IP address reset, but the the custom TCP port I set up did not.

Should be discoverable in a web browser after the factory reset and applying power to the cam while connected to your home network.

you cant use the same IP as the camera; it has to be on the same subnet but a different IP.. you just created a conflict.

cappedup · Apr 17, 2017

Ah, I thought I was trying to match the ip's.

Ok. So static ip of pc Ethernet is now .10 (pic)

Did receive an error message before closing Ethernet properties box. (Pic) haven't manually changed any other network settings.

Reset cam for 1 minute.

PC Ethernet does acknowledge soemthing is plugged into it, which the router does not. (Pic)

Still don't see any evidence of the camera at known ip addresses. (I'm assuming it's reset to .108, although am also trying .200 which is was at last-known working condition.

no gateway, no DNS

Are you saying my settings for this are still incorrect?

Forgive my amateur puzzling.

Was reading another thread about a surge taking out a camera. Any way I can test for that?

He saying leave those blank.

Also reboot computer after setting up ip address

Then open window command console and type ping 192.168.1.108
See if you get any response
