Changing NVR Camera IP assignments to same range as LAN

[rpine]

Question -- I would like my cameras to be on the same network range as the network port of the NVR.
If I change the DHCP range on the NVR (the addresses that it hands out to the cameras, then reboot each camera, will that work?
Will the NVR allow my PC to directly access the cameras, or will it block it?

LAN: 192.168.5.0/24
Would like NVR to assign cameras to 192.168.5.225 - 192.168.5.232

So - can the NVR Network side be 192.168.5.5 with the NVR handing out addresses in the 192.168.5.225 - 192.168.5.232 range?
AND - will the NVR pass the traffic between Network and NVR Switch ports?

Or - do i have to run the cameras into a POE switch on my network and let the NVR discover them?

Why do you want to give the cameras the same IP and open yourself up to that many more chances of the cameras being hacked?

The NVR acts as a firewall intentionally.

If doing what you want to do is simply to access the cameras on a PC, this isn't the best way to access the camera GUI from a PC.

Not sure which NVR you have, but the concept is basically the same. This is for a Dahua OEM NVR:

To get into the camera GUI from the NVR, you need to first access the NVR GUI by going to a computer and opening up a browser (preferably Internet Explorer (yeah we know) but Pale Moon will work as well) and type in the IP address of the NVR and login that way. Next go into the camera settings page on the NVR and look for the Microsoft e Web Browser and select it and it will go to the camera GUI (photo credit bigredfish from his PSA thread). Your screen may look a little different to get into the camera gui and see if doing it this way gets you access to some other features the NVR is blocking - do not worry about the Port number and circle as that was from another issue someone posted.

The user/pw for the cameras should be the same as the NVR unless YOU changed the camera user/pw.


How to enable native Internet Explorer in Windows 10 and 11:

• Open Notepad:
  • Copy then paste the single line of code below into Notepad:
  • CreateObject("InternetExplorer.Application").Visible=true
  • Save as OpenIE.vbs
• Make sure the the file name ends in .vbs not .txt, If it ends in .txt you must rename to .vbs
• Create a shortcut to the above file and double-click it anytime you want native Internet Explorer.

For a Hikvision NVR, you would "enable virtual" host on the NVR... then you can access the cameras from a PC on the LAN using the NVR LAN IP/Port addresses like...http://192.168.154.5:65001 (in my case, 192.168.154.5 is the LAN IP address of the NVR):



Port 65001 is for camera connected to PoE port 1, 65002 for PoE port 2, etc.

Changing the NVR internal switch to the same subnet as the NVR may cause problems, and I don't believe it will auto assign the IP's you want.

The way to do this is by either:
A- plugging the cameras into an external switch (and the NVR into that same switch or any switch on the same LAN network)
or
B- In the networking tab for "Switch" tick the box for "Bridge Mode". This essentially turns your NVR switch into a std network switch. In this case, as in method A, you would need to assign each camera a static IP on your 192.168.5.X segment

Put a POE switch on the network, and thank me later. the lag you could experience trying adjust the settings in the GUI of each cam can get slow when your porting the Camera out of the NVR and into Your BI PC ( if your using BI)
or out to a mobile App. Some NVR's wont allow the internal switch to match the NVR's WAN port Ip range.

I haven’t found the internal switch to be annoyingly slow at all using the NVR switch, perhaps its something on your network or BI?

That's possible....
I had/have the slower thruput NVR (80Mbps) 4108 model. When i was running 5-6 cameras thru the NVR switch to my Cisco gigabit switch there was slow loading of the individual camera GUI's. the wait time became frustrating. Sometimes it would not finish loading. and the slow reaction when bumping the zoom up or down made it annoying.
So I moved the cams to the POE ports on the Cisco, and slow loading/lag/wait time to individual cam GUI's disappeared. And the NVR's responsiveness returned to normal.

Always a pain in the ass to find network bottlenecks. Especially for us non-network edumacated guys
