@jason Looking at your NVR screen shot, I notice that your three cameras belong to the same network 192.168.0.XXX. That means all your three cameras are connected to the switch of your network and not your NVR PoE internal switch. Is that so?
Usually the first 8 camera entries in the NVR list are the ones connected to the NVR PoE switch and usually have consecutive IP numbers starting from 192.18.0.2 up to 192.168.0.9. In your case the second camera has an IP 192.168.0.11 which is outside the range of the NVR internal IP range. It seems that at some point in the past you connected the second camera at your main LAN (not at the NVR) and then you reconnected the camera at the NVR and therefore the NVR kept the external IP hence the XXX.XXX.XXX.11.
Also usually the inernal NVR IP range is 192.168.254.2 up to the number of the cameras the NVR is licensed. You say that your LAN is on the range 192.168.0.XXX. Therefore it seems that you have changed the NVR internal IP range to 192.168.0XXX in order to match your LAN IP range. That s wrong, or at least enough to create the problems you have even though the NVR internal PoE lan is isolated from the external LAN.
Also there is a documented problem or disfunctionality regarding the assignement of the camera IPs between the internal PoE switch and the external LAN, in another thread in this forum.
There are a lot of contradictions in you setup.
Please confirm my assumptions above.
Here is my proposal.
1. Diconnect all your cameras fom everywhere and understad all my proposed steps before you execute them.
2. Ensure that the IPs of the NVR internal LAN have consecutive IPs starting from XXX.XXX.XXX.2 up to XXX.XXX.XXX.9. If that is not the case, then try to change all the IPs at the NVR camera list manually to make them consecutive.
3. Since your external LAN is of the range 192.168.0.XXX then ensure the IP of the NVR is in this range, say 192.168.0.100. Ensure that this IP IS NOT in the DHCP IP range of your router. If it is, either limit the DHCP range pool OR change the NVR IP outside the DHCP IP pool range. Mind you, so far I am not talking about the NVR internal PoE LAN swich.
4. Ensure that you can access the NVR web interface from your LAN side.
5. Lets configure now the NVR internal PoE switch for the cameras. Set the NVR internal cameras gateway to 192.168.254.1. This is the usual default IP from HIK.
6. Reboot the NVR and you must notice that the IPs in the NVR camera list have changed to 192.168.254.2 - 192.168.54.9 (even though you have no cameras connected).
We have finished with the NVR setup. Continue with the cameras.
7. At this moment your cameras have IPs like 192.168.0.XXX. If you connect them to your LAN, you will be able to access them normaly. Change the IP of one camera to 192.168.254.2, the gateway to 192.168.254.1 and the subnet mask to 255.255.255.0. After the IP change and camera reboot you will not be able to access the camera from the LAN, which is normal. (Remember if you want to change the camera IP, change your laptop IP to 192.168.254.1 and connect the camera and the laptop to a switch or router on their own, avoid crossover cables)
8. Connect the camera to your NVR and reboot the NVR. You shoud be able to see the camera in the NVR camera list. If you cannot see the camera or you get any error, remember that you must set the camera password correctly in the camera definition of the NVR to the camera password you have defined in the camera. Remember the NVR is just another user accessing the camera automatically. If the NVR tries to log to the camera with the wrong camera password you will get an error.
9. If your NVR has the "Virtual host" feature enable it. Now this camera is accesibe from the LAN with an address 192.168.0.100:65001 (i.e. the NVR IP plus the internal ports 65001-65008). The next camera will be accessible as 192.168.0.100:65002 and so on.
10. If above steps are succesfull, repeat steps 7-9 for every camera seperately and assigning a camera IP like 192.168.254.3 and so on. Never connect many cameras all of them at the first time.
If you have any problems at any of the above steps, report back and send us screen shots of the network settings of the NVR and the camera. Ensure that you always tell us the following information.
1. The LAN router IP
2. The DHCP IP pool range of the router
3. The IP of the NVR
4. The IP of the NVR internal gateway of the PoE switch
5. The IPs of the camera.
Apologies for the long post but clear instructions are always long (the occupational hazard!!!).
