Create a custom IP configuration NVR its internal PoE cameras

Steps to Configure:

1. Check NVR NIC Settings:
   • Ensure that the NVR’s NIC1 is set to a static IP address (e.g., 192.168.100.3) with the appropriate subnet mask (e.g., 255.255.255.0) and gateway, if applicable.
2. Configure the Internal PoE Switch (NVR Port):
   • Many NVRs with built-in PoE switches use a default subnet for internal PoE cameras (e.g., 10.x.x.x or 192.168.x.x).
   • Access the PoE switch settings in the NVR menu, and look for options to change the subnet to match your desired range (e.g., 192.168.100.x).
3. Assign IPs to Cameras:
   • Log in to the NVR’s camera management interface.
   • Manually assign static IPs to the cameras, starting from .6 to .10, within the same subnet as NIC1 (e.g., 192.168.100.6, 192.168.100.7, etc.).
   • Set the gateway for the cameras to match NIC1 (e.g., 192.168.100.3).
4. Disable DHCP (Optional):
   • If the NVR acts as a DHCP server for the internal PoE cameras, you may need to disable DHCP and manually configure all cameras.
   • Alternatively, configure the NVR’s DHCP server to assign IPs only within your desired range.
5. Ensure Network Communication:
   • Check that NIC1 and the internal PoE cameras can communicate within the same subnet.
   • Verify if the NVR allows traffic routing between NIC1 and its internal PoE ports.

Challenges to Consider:

1. NVR Firmware Limitations:
   • Some NVRs are hardcoded to use a specific subnet for PoE cameras, and it may not be possible to change this. In such cases, you might need to use a separate external PoE switch.
2. Routing Between NICs:
   • If your NVR has multiple NICs, ensure that the routing configuration allows communication between the NICs and the cameras in the same subnet.
3. Camera Compatibility:
   • Ensure the cameras support manual IP configuration and are compatible with the NVR’s subnet.
4. Internal vs. External Network Segmentation:
   • Consider network security and whether you need to isolate the PoE camera traffic from the external network traffic on NIC1.

Verification:

After configuration:

• Test the connectivity by pinging the cameras from the NVR and vice versa.
• Ensure that the cameras are properly detected and displayed in the NVR interface.
