Some Issues with Troubleshooting steps

Unable to Access Camera on NX

If NX Witness cannot access an IP camera connected to the Katana switch, follow these steps to troubleshoot the issue:

  1. Check LAN Connection

    • Ensure Katana LAN is connected to the Katana switch
    • Identify active interface (e.g. enp0s31f6)
    ip a

  2. Check Camera IP Reachability

    ping <camera-ip>
    • If ping works → NX configuration issue
    • If ping fails → continue below

  3. Camera IP on 192.168.50.0/24

    Ping existing Katana IP:

    ping 192.168.50.17

    If unreachable, add an additional IP (non-conflicting):

    sudo ip addr add 192.168.50.100/24 dev enp0s31f6

    Retry pinging the camera IP.

  4. Camera IP on a Different Subnet

    Add a temporary IP in the camera’s subnet:

    sudo ip addr add 192.168.X.100/24 dev enp0s31f6

    Example:

    sudo ip addr add 10.10.10.100/24 dev enp0s31f6

    Retry pinging the camera IP.

    If it is pingable ➕ Add additional IP using Linux GUI

  5. If Camera Is Still Not Reachable

    • Check camera gateway configuration
    • Ensure gateway is reachable
    • Confirm no IP conflict
    • Verify camera is active on switch port
    • Power-cycle camera (PoE off/on)

  6. If Ping Works but NX Cannot Access Camera

    • Verify camera credentials
    • Check NX status (Offline / Unauthorized)
    • Add camera manually using IP
    • Restart NX Media Server
