When your PC and IP camera are on different subnets, you won’t be able to connect to the camera’s web interface. This is a common issue when setting up surveillance or wireless transmission systems. Fortunately, you can solve it quickly with a few simple network adjustments.

Why You Can’t Access the Camera

Let’s look at a typical case:

PC IP: 192.168.10.85 → Network: 192.168.10.0/24
Camera IP: 192.168.2.254 → Network: 192.168.2.0/24

These two devices are on different network segments (subnets).
Without a router or proper configuration, your PC simply doesn’t know where to send packets destined for 192.168.2.x.

راه حل 1: Change the PC IP to Match the Camera’s Subnet

این است quickest and easiest method, suitable when your computer is directly connected to the camera or connected via a simple switch.

ویندوز

باز کنید شبکه & Internet Settings → Ethernet → Change adapter options.
Right-click your network adapter → Properties → Internet Protocol Version 4 (TCP/IPv4) → Properties.
Set the following: IP address: 192.168.2.100 Subnet mask: 255.255.255.0 Default gateway: leave blank
کلیک کنید باشه, then open your browser and go to http://192.168.2.254.

💡 After configuration, don’t forget to change your IP back to its original address (به عنوان مثال, 192.168.10.85) to restore normal internet access.

لینوکس

Find your network interface: ip a (مثال: eth0, enp3s0, ens33)
Assign a temporary IP: sudo ip addr flush dev eth0 sudo ip addr add 192.168.2.100/24 dev eth0 sudo ip link set eth0 up
Visit http://192.168.2.254 in your browser.
When done, revert to your original IP: sudo ip addr flush dev eth0 sudo ip addr add 192.168.10.85/24 dev eth0 sudo ip link set eth0 up

راه حل 2: Add a Secondary IP (Keep Internet Access)

If your PC must stay connected to the internet or another network, شما می توانید add a second IP address instead of changing the main one.

ویندوز

رفتن به Ethernet → Properties → IPv4 → Advanced.
کلیک کنید Add under “IP addresses” and enter: IP address: 192.168.2.100 Subnet mask: 255.255.255.0
کلیک کنید باشه.
Now your PC has both:
- 192.168.10.85 (for the main network)
- 192.168.2.100 (for the camera)

لینوکس

Add the second IP: sudo ip addr add 192.168.2.100/24 dev eth0
تایید کنید: ip a show dev eth0 You should see both IPs listed.
Access the camera via: http://192.168.2.254

This setup is temporary. After reboot, you can repeat the command or make it permanent using your system’s network configuration tool.

راه حل 3: Use a Router or Static Route (For Larger Networks)

If your PC and camera are connected through different routers or VLANs, you’ll need routing between the two subnets.

On the main router (به عنوان مثال, 192.168.10.1), add a static route:

Destination network: 192.168.2.0
Subnet mask: 255.255.255.0
Next hop: 192.168.10.x  (device that connects to the 192.168.2.x network)

Once routing is active, both devices will be able to communicate normally.

Troubleshooting Checklist

If you still can’t access the camera:

Check the network cable و camera’s link lights.
Ensure your firewall isn’t blocking local connections.
Try pinging the camera: ping 192.168.2.254
Confirm the camera’s IP address using the manufacturer’s search/config tool.
Restart your network interface or router after changes.

نتیجه گیری

When your PC and IP camera are on different subnets, they can’t communicate directly — but you have multiple easy solutions:

Temporarily change your PC’s IP
Add a secondary IP for dual access
Configure routing for multi-network setups

Once both devices share a compatible network segment, you’ll be able to log in to your IP camera’s web interface and begin streaming, ضبط کردن, or configuring it right away.
