Setting operation Day and Night settings
- Thread starter JPmedia
- Start date
Both LPR cam issues seem to be sorted with DAY/NIGHT switchover. I do need to make some slight schedule adjustments, but they're working great so far. A big thanks to bigredfish for his help and patience on this, it is very much appreciated!

Ok, update. Tried logging into the web GUI's of the LPR cameras to make some adjustments this morning and I'm getting a blank page regardless of browser (IE or Pale Moon). Any ideas on what the issue might be?

That was the first thing I did was to flush the browser cache and history, closed and reopened the browsers and even restarted the laptop, no joy. I had access last night. The reason I wanted to open the web page on the cameras was that I noticed the one LPR went out of focus in the early morning. I wanted to check some settings.
I just tried to access the web GUI on an older Windows XP laptop with no luck either. All other cameras I have access to the web pages, except the LPR cameras on both computers and all browsers (Google, IE and Pale Moon 32)
After the cache clearing, the next option is to delete the extensions/plug-ins, and if that doesn't work then it is delete the browser history.
I have seen a few instances where the browser history is holding on to some item and clearing the history and I can see the camera again.

Here's the weird thing, I did an IP scan of the network with the 2 LPR cameras disconnected from the NVR and then connected one at a time to a POE switch and direct to computer. Neither LPR camera IP address is found on the network. If I connect my spare 5442 to the POE switch, it shows up on the network as the usual address.
I'm not sure why neither LPR camera is showing an IP address with an IP scan
Is the spare 5442 on the same IP subnet as your network?
By default, the NVR assigns IP subnets in the 10.x.x.x range and it may not be seen as being on the network as they are not on the same subnet.
If you make your computer the same subnet of the cameras, you will be able to access it.
Which NVR model and firmware date do you have?
Neither LPR camera is connected to the NVR currently. If I connect either one to the POE switch directly, neither report an IP address and I scanned two different sets of values. If I connect the 5442 to the POE switch an IP scan returns with the usual 192.168.X.XXX IP address. I did not change the IP address on any of the cameras from default, only thing that changed was the password, so any camera I connect to the POE switch separately, should theoretically return the usual IP address, no?
If you connected the LPR to the NVR POE port, the NVR will assign it a static IP address of 10.x.x.x. and the only way to access it if you disconnect it from the NVR is to make your computer subnet 10.x.x.x. Or do a factory reset to get the camera back to 192.168.1.108
If you never connected the cameras to the NVR POE ports (that would have assigned static 10.x.x.x addresses) and never assigned them static IP addresses, then you have an IP conflict as every camera would have the same 192.168.1.108 address and that can cause the blank screen also when trying to login.

Ok, just so I understand what you're saying - if it starts with an IP address of 192.168.1.108, once plugged into the NVR, the NVR will assign a 10.X.X.X IP address permanently?

Generally yes. ALL new Dahua cameras come with 192.168.1.108 by default.
When you plug it into a PoE NVR the NVR will automatically switch it to 10.1.1.x so its internal switch takes over (assuming you haven t manually given the camera a different static IP
This works as long as you havent messed with the IP setting on the camera. Otherwise, all best are off and its up to you to manually assign it or factory default it

As long as you dont mess with the IP at all on the camera, I have successfully moved them from NVR to a switch with 192.168.1.X and back to the same original NVR port and they have adopted the 10.1.1.x IP again. (DHCP mode)
But this isnt guaranteed depending on NVR model and FW versions
So its probably sitting on your switch with a 10.1.1.x address
Best thing is to manually assign the IP, even if on a different device BEFORE you unplug and move it.
So when I want to take a camera from the NVR PoE to an external switch, first thing I do is, while still connected to the NVR, I switch the IP on the camera to Static 192.168.1.X, hit save, close the browser, then unplug it quickly.
Then I plug it into the external switch and its there and done.
^^^^
Same thing in reverse if taking it from an external switch to the NVR
Of course you want to avoid using 192.168.1.108 or duplicating any other IPs already being used on the 192.168.1.X network

Lets go back to this though, when you say you're getting a blank page, show a pic. Are you getting NOT FOUND or is it showing the 192.168.1.X address in the address bar and no message at all?
If you havent changed anything or moved them since the last good login, it shouldnt be the IP address
What IS the IP address you think they should be at, were at yesterday?

Ok its not a networking problem and I'm guessing you can see the camera fine in live view of the NVR or DMSS or SmartPSS whatever, so not a camera issue
There is a camera at that address. (name Web and little icon)
Its a browser issue where I started
The browser isnt fully rendering the page. Plugin or browser

Yes, we have ATT here and they supply the modem/router unit. The 192.169.2.X was what I chose to make it a little harder for outside entities to get in. Back in 2020 we had Spectrum until a Spectrum employee across the street started playing games with everyone's internet by back-feeding through the lines.
I asked previously which NVR make/model and firmware date.
My neighbors NVR does this trying to access the newer GUI thru an older GUI NVR. Sometimes it works and sometimes it doesn't. When it doesn't work, we pull the camera off the NVR and change the computer to the 10.x.x.x subnet and access that way.
