The app supports Dahua, Hikvision, IMOU, EZVIZ, HiLook, and Xiongmai cameras out of the box, plus MikroTik and DrayTek routers, pfSense firewalls, and any device that can run a curl command. It also includes built-in network diagnostic tools for field troubleshooting.
Why FastDDNS Works Better in the Field
If you install or maintain CCTV systems, you know how on-site configuration usually goes: a ladder, a laptop balanced on something unstable, and a web browser open to each device's admin panel while you type in DDNS server addresses, device IDs, DNS settings, and credentials one field at a time. Repeat that for every camera and every NVR on the job.
FastDDNS eliminates that workflow. Connect your phone to the same WiFi network as your devices, open the app, and the Auto-Setup Wizard guides you through each step:
- Discovers devices on your local network automatically
- Detects each device's brand without manual input
- Pushes the full DDNS configuration — server addresses, device IDs, DNS servers, and credentials — in one tap
No manual typing. No switching between browser tabs. No laptop required.
After setup, the app monitors every hostname and sends push notifications the moment an IP address changes. If port forwarding is not working or the ISP is blocking inbound connections, the built-in port checker and CGNAT detector tell you immediately — while you are still on-site and can fix it.
Set Up Cameras in Fewer Steps
The Auto-Setup Wizard helps installers save time on repetitive setup tasks. It handles the full configuration flow in a single guided process:
- Device registration with FastDDNS
- DDNS configuration written directly to the device
- DNS server settings applied
- Post-setup hostname verification
You select the brand, enter device credentials, and the app walks you through each step.
Supported Cameras at a Glance
| Brand | What the App Configures |
|---|---|
| Dahua / IMOU | Registers device, writes DDNS config, sets DNS servers, optionally configures motion detection and email alerts |
| Hikvision / EZVIZ / HiLook | Auto-registers device, pushes DDNS and DNS settings via the ISAPI interface over HTTP |
| XM / Xiongmai | Configures relay tunnels and DDNS settings for 34567-port devices |
Dahua and IMOU
The app connects to your Dahua camera or NVR over the local network, registers the device with FastDDNS, writes the DDNS configuration directly to the device, sets the correct DNS servers, and optionally enables motion detection with email alerts. The process runs from your phone and reduces the need for browser-based configuration or manual data entry.
Hikvision, EZVIZ, and HiLook
FastDDNS communicates with Hikvision-based devices through the ISAPI interface over standard HTTP. The app auto-registers the device, pushes DDNS settings and DNS configuration, then verifies that the hostname resolves correctly. Because it uses the device's standard web interface, setup stays simple and broadly compatible across Hikvision, EZVIZ, and HiLook models.
XM and Xiongmai
For Xiongmai-based equipment — including generic CCTV devices that communicate on port 34567 — FastDDNS configures relay tunnels and DDNS settings through the device's native protocol. The wizard handles device discovery, credential validation, configuration writing, and post-setup port verification with automatic error recovery if any step fails.
Create Hostnames and Track IP Changes
FastDDNS gives you a complete DDNS dashboard on your phone:
Hostname management — Create new hostnames, edit labels and notes, and access hostname credentials when needed. Each hostname displays its full configuration block including server addresses, device IDs, DNS server IPs, and ready-to-use update URLs for Linux, pfSense, and MikroTik clients.
Real-time IP monitoring — The app polls your hostnames automatically and logs every IP change with a timestamp and HTTP status code. You get a complete update history showing exactly when your ISP changed your address, how often changes happen, and whether any updates failed.
Push notifications — Receive instant alerts via Firebase Cloud Messaging when an IP address changes, when a hostname is about to expire, or when your subscription needs attention. Tapping a notification takes you directly to the relevant hostname through deep linking.
Port accessibility checker — Verify whether a specific port on your device is reachable from the internet, right from the hostname detail screen. This tells you immediately whether port forwarding is configured correctly.
Handle CGNAT With CCTV Relay
Carrier-Grade NAT (CGNAT) is one of the most common reasons remote access fails. When your ISP places you behind CGNAT, no amount of port forwarding will make your devices reachable from the outside.
FastDDNS includes a CGNAT Checker tool that detects whether your connection is behind CGNAT and runs a NAT loopback test. If CGNAT is confirmed, the app offers relay tunnels for Dahua, Hikvision, and XM cameras as a workaround. The relay feature walks you through port configuration, DDNS setup, and device registration with multi-step progress tracking and automatic error recovery.
Use FastDDNS With Routers and Other Devices
The Auto-Setup Wizard is not limited to cameras. FastDDNS also supports guided DDNS configuration for routers, firewalls, and general-purpose systems:
MikroTik (RouterOS) — The app configures network interfaces, IP addresses, gateways, DNS servers, port forwarding rules, and DDNS update scripts on MikroTik routers directly from your phone.
DrayTek (Vigor series) — Guided DDNS setup with step-by-step instructions tailored to DrayTek's interface.
pfSense — Provides the correct update URL and credentials for pfSense's built-in Dynamic DNS client.
Windows — Installs and configures a lightweight DDNS update client that keeps your hostname current automatically.
Linux and macOS — Generates a ready-to-use curl command or cron job for any system with a command line.
Any HTTP client — Any device or script that can make an HTTP GET request to the FastDDNS update URL will work. This covers custom setups, IoT devices, and automation workflows.
Built-in Network Tools
FastDDNS includes practical network tools for field troubleshooting: LAN Scanner, Ping and Traceroute, Port Checker, DNS and WHOIS lookups, and CGNAT detection. All tools are accessible from a single screen inside the app.
