NVR / Camera System
Lorex NVR
Lorex NVRs are locked to Lorex DDNS. Use the pfSense/router workaround instead.
1
Log into your Lorex NVR
Lorex NVRs are locked to the Lorex DDNS cloud service and do not support third-party DDNS providers.
The best workaround is to run the check-in script on your pfSense or OPNsense router instead — since the NVR sits behind the router, they share the same WAN IP.
See the pfSense / OPNsense guide for setup instructions.
This is a Lorex firmware restriction. Very old Lorex firmware may show NO-IP as an option — if so, continue with steps 2 onward.
2
Navigate to Network → DDNS
From Main Menu go to: Settings → Network → DDNS (or in the web interface: Configuration → Network → DDNS)
3
Configure DDNS settings
Enable DDNS and fill in the settings:
• Enable: ✓
• Type: NO-IP or Custom
• Server: greatddns.com
• Domain: your-hostname (subdomain only, e.g. "mylorex")
• Username: your GreatDDNS username
• Password: your GreatDDNS password
• Interval: 5 minutes
If you see a "Lorex DDNS" option, skip it — that is a paid Lorex cloud service. Use NO-IP or Custom instead.
4
Alternative: Custom HTTP update URL
If your Lorex firmware supports a custom update URL, enter this directly:
https://greatddns.com/api/checkin/?token=YOUR-DEVICE-TOKEN
This works on newer Lorex firmware that allows a fully custom DDNS endpoint.
5
Save and verify
Save the settings. Your NVR will attempt an update within 5 minutes. Check your GreatDDNS dashboard to confirm the device is showing as Online.
6
Set up port forwarding
To view your cameras remotely, forward these ports on your router to the NVR's local IP:
• HTTP: 80 or 8080
• RTSP: 554
• Media: 35000 (Lorex default)
Check your Lorex NVR's Network settings for the exact ports — they can vary by model.
