Before diving into the technical steps, it’s important to understand why you might want to change the VLAN for your G4 Doorbell.
Most home networks operate on a single flat network—meaning all devices, from your laptop to your smart fridge, share the same network space. While this works fine for basic use, it poses security risks. If one device is compromised, it could potentially access others on the same network.
VLANs solve this by creating separate virtual networks within your physical infrastructure. For example, you might have:
– VLAN 10: Main devices (laptops, phones, tablets)
– VLAN 20: IoT devices (smart lights, thermostats, cameras)
– VLAN 30: Guest network
By placing your G4 Doorbell on a dedicated IoT VLAN (like VLAN 20), you isolate it from your primary devices. This reduces the risk of unauthorized access and improves network performance by reducing unnecessary traffic.
Additionally, some advanced users configure VLANs to prioritize certain types of traffic. For instance, video streams from your doorbell might be given higher priority on a specific VLAN to prevent lag or buffering.
So, changing the VLAN isn’t just about security—it’s about smarter network management.
Prerequisites: What You’ll Need
Before making any changes, ensure you have the following:
1. Admin Access to Your Network Switch
Most G4 Doorbells are powered and connected via Power over Ethernet (PoE). This means they plug directly into a PoE switch—often a Ubiquiti UniFi Switch. You’ll need administrative access to this switch to modify VLAN settings.
If you’re using a UniFi Dream Machine (UDM) or UDM Pro, you can manage everything through the UniFi Network Application. For third-party switches, you may need to log in via a web interface or CLI.
2. The UniFi Network Application
If you’re using Ubiquiti equipment (which is common with G4 Doorbells), the UniFi Network Application is your control center. Make sure it’s installed on a computer, phone, or accessed via the cloud.
You can download it from the official Ubiquiti website or access it through your UDM’s web interface at https://unifi.yourdomain.com or https://192.168.1.1 (default IP).
3. The Correct VLAN ID
You’ll need to know which VLAN you want to assign to the doorbell. This should be part of your overall network plan. Common VLAN IDs for IoT devices are 10, 20, or 100—but it depends on your setup.
If you haven’t created the VLAN yet, you’ll need to do that first in your network settings.
4. A Static IP or DHCP Reservation
Changing VLANs can sometimes cause devices to lose their IP address. To avoid this, assign a static IP or set up a DHCP reservation for your G4 Doorbell. This ensures it always gets the same IP, even after network changes.
You can find the doorbell’s MAC address in the UniFi Network Application under “Devices” > “G4 Doorbell” > “Properties.”
5. A Backup of Your Current Configuration
Before making any changes, back up your current network settings. In the UniFi Network Application, go to Settings > Maintenance > Backup and download a backup file. This lets you restore your setup if something goes wrong.
Step-by-Step: How to Change the VLAN of Your G4 Doorbell
Now that you’re prepared, let’s walk through the actual process of changing the VLAN.
Step 1: Log in to the UniFi Network Application
Open your web browser and navigate to your UniFi controller. If you’re using a UDM, go to https://192.168.1.1 (or your custom domain). Log in with your admin credentials.
Once logged in, you’ll see the dashboard with all your connected devices.
Step 2: Locate Your G4 Doorbell
In the left-hand menu, click on Devices. Scroll or search for your G4 Doorbell. It should appear with its name (e.g., “Front Door”) and show its current status (online/offline).
Click on the doorbell to open its properties panel.
Step 3: Note the Current Network Settings
Before making changes, take note of:
– Current IP address
– MAC address
– Current VLAN (if visible)
– Connected switch port
This information will help you troubleshoot if the doorbell goes offline.
Step 4: Create or Confirm the Target VLAN
If you haven’t already created the VLAN you want to use, do so now.
Go to Settings > Networks. Click Add Network and choose VLAN Only or Corporate (depending on your needs).
Fill in:
– Name: e.g., “IoT Devices”
– VLAN ID: e.g., 20
– IP Settings: Assign a subnet (e.g., 192.168.20.1/24)
– DHCP: Enable if you want devices to get IPs automatically
Save the network.
Step 5: Configure the Switch Port for the New VLAN
Now, you need to tell the switch port (where the doorbell is plugged in) to use the new VLAN.
Go to Devices and find the switch your doorbell is connected to. Click on it, then go to the Ports tab.
Find the port number where the G4 Doorbell is plugged in (e.g., Port 3).
Click the gear icon next to the port and select Edit.
In the port settings:
– Set Native Network to the new VLAN (e.g., “IoT Devices” or VLAN 20)
– If using tagged VLANs, ensure Tagged Networks includes the new VLAN
– Make sure PoE is enabled (the doorbell needs power)
Save the changes.
Step 6: Assign a Static IP or DHCP Reservation
To prevent IP conflicts, assign a fixed IP to the doorbell.
Go to Settings > Networks and select the new VLAN network (e.g., “IoT Devices”).
Click on DHCP Reservations and then Add Reservation.
Enter:
– Device Name: G4 Doorbell
– MAC Address: (copy from the doorbell’s properties)
– IP Address: e.g., 192.168.20.50
Save the reservation.
Step 7: Reconnect the Doorbell (If Needed)
In most cases, the doorbell will automatically reconnect to the new VLAN within a few minutes. However, if it goes offline, you may need to power-cycle it.
Unplug the Ethernet cable from the doorbell or switch, wait 10 seconds, and plug it back in. This forces the device to renegotiate its network connection.
Step 8: Verify Connectivity
Return to the Devices section and check if the G4 Doorbell is back online.
Click on it and confirm:
– It shows the new IP address (e.g., 192.168.20.50)
– The status is “Connected”
– The VLAN is correctly assigned
You can also test functionality:
– Open the UniFi Protect app
– View the live feed from the doorbell
– Test motion detection and two-way audio
If everything works, congratulations—you’ve successfully changed the VLAN!
Troubleshooting Common Issues
Even with careful planning, things can go wrong. Here are some common issues and how to fix them.
Issue 1: Doorbell Goes Offline After VLAN Change
This is the most common problem. It usually happens because the doorbell can’t obtain an IP address on the new VLAN.
Solution:
– Check that the switch port is correctly configured for the new VLAN
– Ensure DHCP is enabled on the target VLAN network
– Verify the DHCP reservation is correctly set
– Power-cycle the doorbell and switch port
Issue 2: No Video or Audio in UniFi Protect
If the doorbell is online but the feed is blank or audio doesn’t work, the VLAN might be blocking necessary traffic.
Solution:
– Ensure the VLAN allows traffic on ports used by UniFi Protect (typically UDP 7443, 7080, 7442)
– Check firewall rules—some VLANs block inter-VLAN communication by default
– If using a UDM, go to Settings > Routing & Firewall > Firewall Rules and allow traffic between VLANs if needed
Issue 3: Doorbell Gets Wrong IP Address
If the doorbell receives an IP from the wrong subnet, the DHCP reservation may not be working.
Solution:
– Double-check the MAC address in the reservation
– Ensure the reservation is on the correct VLAN network
– Restart the DHCP service on your router or UDM
Issue 4: PoE Not Working After VLAN Change
If the doorbell loses power, the PoE settings on the switch port may have been reset.
Solution:
– Go back to the switch port settings
– Confirm PoE is enabled
– Try a different port or cable to rule out hardware issues
Issue 5: Can’t Access UniFi Network Application
If you’re locked out after changing VLANs, you may have accidentally isolated your admin device.
Solution:
– Connect your computer directly to the main network (not the IoT VLAN)
– Use a wired connection to access the UDM
– Restore from a backup if necessary
Best Practices for VLAN Management
To keep your network running smoothly, follow these best practices:
1. Document Your Network
Keep a simple diagram or list of:
– VLAN IDs and purposes
– Device IPs and MAC addresses
– Switch port assignments
This makes troubleshooting much easier.
2. Use Descriptive Names
Instead of “VLAN 20,” name it “IoT_Cameras” or “Smart_Devices.” This improves clarity.
3. Limit Inter-VLAN Traffic
Only allow necessary communication between VLANs. For example, your main network may need to access the doorbell for video, but the doorbell shouldn’t access your laptop.
Use firewall rules to enforce this.
4. Regularly Update Firmware
Keep your UDM, switches, and G4 Doorbell firmware up to date. Updates often include security patches and VLAN-related fixes.
5. Test After Changes
Always test functionality after reconfiguring VLANs. Don’t assume it works—verify video, audio, and motion detection.
