What should I do if my camera's default IP (192.168.1.108) is already in use?

If your camera's default IP (192.168.1.108—common for Dahua, Lorex, and many unbranded units) is already in use by another device, you will experience an IP Conflict. This prevents you from accessing the camera's web interface and can cause both the camera and the other device to drop offline.

Here is the professional workflow to resolve this and move your camera to a "safe" address.

1. The "Manufacturer Tool" Workaround (Easiest)

Manufacturer search tools (like Dahua ConfigTool or SADP) use "Broadcast" packets that can see the camera even if its IP is conflicting or on a different subnet.1


  • The Fix: 1. Download and run the Dahua ConfigTool (or your brand's equivalent).2

    2. The tool will show a list of devices.3 Look for the camera with the 192.168.1.108 address.

    3. Click the "Modify IP" (pencil icon).

    4. Change the address to something unique (e.g., 192.168.1.210).

    5. Enter the camera’s password to confirm the change.+1

2. The "Direct-to-Laptop" Isolation

If the network conflict is so severe that the tool can't find the camera, you must isolate it from the rest of your network.4


  • The Fix:

    1. Unplug the camera from your router or switch.

    2. Plug the camera directly into your laptop’s Ethernet port (use a PoE injector if the camera isn't battery-powered).5


    3. Manually set your laptop's IP address to 192.168.1.5.

    4. Open a browser and go to http://192.168.1.108. Since the "other" device is no longer in the way, the camera's login page will load.

    5. Go to Network Settings and change the IP to a new, unique address.

    6. Plug everything back into your main router.

3. Clear the "ARP Cache"

Sometimes your computer "remembers" that .108 belongs to a different device (like an old printer), even after you change the camera's IP.

  • The Fix: Open the Command Prompt as Administrator and type:

    arp -d *

    This clears the memory of which MAC address belongs to which IP, forcing your computer to look for the camera's new address from scratch.

Pro-Tips to Avoid Future Conflicts

Rule

Action

Check the Range

Before assigning a new IP, type ping 192.168.1.X in your computer to see if the new address you want is already taken.

DHCP Reservation

Log into your router and "reserve" an IP for your camera's MAC address so the router never gives that address to a guest's phone.

Go High

Assign cameras addresses high in the range (e.g., .200 to .254). Most routers start giving out addresses at the bottom (.2, .3, etc.), so "going high" avoids future collisions.
