Set up DDNS on your cameras
from your phone
Create a hostname, write the DDNS settings straight into a Dahua or Hikvision camera over WiFi, and watch every IP change from one app. No laptop on the ladder.
Works with 50+ camera brands · Hostname updates in under 60 seconds
Built for the job, not the desk
On-site configuration usually means a ladder, a laptop balanced on something unstable, and a browser open to each device while you type server addresses and credentials one field at a time. Repeat for every camera on the job.
No laptop required
The whole flow runs on the phone you already carry. Connect to the site WiFi and start configuring.
Scan instead of typing
The app lists every device on the network with its open ports and vendor, so you know what you are working with before you start.
Find problems before you leave
Built-in port and CGNAT checks tell you whether remote access will actually work while you are still on site and can still fix it.
Auto Setup writes the configuration for you
Open a hostname, tap Auto Setup for CCTV Camera, and the wizard registers the device, writes the DDNS configuration into it, applies the right DNS servers, and verifies the hostname afterwards.
Have the device's address and the port its admin interface answers on, plus an admin username and password. The port field defaults to 80 for devices reached over HTTP, but use whatever the device actually listens on — 37777 on a Dahua recorder, 34567 on a Xiongmai one.
Find the device
Type the LAN IP and port, or let Scan IP and Scan CCTV find it. The sheet shows your current WAN IP so you can fill that field with one tap.
Pick the brand
Choose from Hikvision, Dahua, EZVIZ, IMOU, XMEye, HiLook and Tiandy, or use Other for anything else and follow the guided manual steps.
Enter the login and start
Give the wizard the camera's own username and password and it does the rest. If a step fails it reports which one, so you know whether the problem is the credentials, the port or the network.
Auto Setup talks to the device directly, so in practice you run it with your phone on the same network as the camera. Working remotely is only possible if the device's port is already open. Managing hostnames and watching IP changes works from anywhere either way.
What the app configures, brand by brand
| Brand | What the app configures |
|---|---|
| Dahua / IMOU | Registers the device, writes DDNS config, sets DNS servers, and can enable motion detection with email alerts |
| Hikvision / EZVIZ / HiLook | Auto-registers the device and pushes DDNS and DNS settings through the ISAPI interface over HTTP |
| XM / Xiongmai | Configures DDNS on devices that speak the native protocol on port 34567 |
| Tiandy | Selectable in the brand picker |
Anything else falls back to guided manual steps. Read the full auto-configuration walkthrough
A DDNS dashboard in your pocket
The app is not only a setup tool. Every hostname you own is here, with its full configuration block and its history.
Manage every hostname
Create hostnames, edit labels, keep private notes, move one between packs, and see how much of your quota is used and when it expires.
See every IP change
The home screen shows your WAN IP with the country, region and ISP behind it. Each hostname keeps an update history with timestamps and status codes.
Get told the moment it changes
Turn on IP change alerts per hostname and get a push notification when the address moves or a hostname is about to expire.
Check the port without leaving
Test whether a port on your device is reachable from the internet straight from the hostname screen.
Twelve network tools, one tab
The Tools tab is a small toolbox for field work, grouped into three sections.
Check for CGNAT before you configure anything
Carrier-Grade NAT is the one thing no amount of camera configuration can fix. When your ISP puts you behind CGNAT you do not have a real public IP, so connections coming in from the internet are blocked.
Be clear about what DDNS can and cannot do here: Dynamic DNS does not get you past CGNAT. It keeps a hostname pointed at your public IP as that IP changes, but it cannot create a public IP you were never given.
The CGNAT Checker in the app tells you which situation you are in and runs a NAT loopback test at the same time. If it reports CGNAT, the fix is with your ISP: ask for a public IP address, which many offer as a paid option.
The other half of the same problem is port forwarding. Even with a real public IP you still need the relevant ports open on the router — 554 for RTSP, 37777 for Dahua — because DDNS only solves the changing-address half. Test a port from your browser
Routers, firewalls and everything else
Cameras are not the only thing on a job. Under DDNS Configuration, every hostname screen carries ready-made parameter blocks you can open and copy on the spot.
Devices that let you change the server address
The values that replace another provider's endpoint, which is usually all a Hikvision or Dahua recorder needs.
CCTV camera, NVR and DVR
The generic hostname, username and password block.
Dahua Auto Register
For recorders with no DDNS menu. The device dials out to the registration server, so it is the one case that does not need an inbound port open.
DrayTek Vigor
The fields to fill in on DrayTek's own DDNS menu.
Windows
A lightweight update client that keeps the hostname current on its own.
Linux via crontab
A ready-to-paste curl line for a Raspberry Pi, CentOS or Ubuntu box.
pfSense
The update URL and credentials for the built-in Dynamic DNS client.
MikroTik RouterOS
The update script and its parameters.
Underneath it all the update endpoint is DynDNS-compatible, so anything that can make an HTTP request will work — a NAS, an IoT board, your own script.

Frequently asked questions
Is the FastDDNS app free?
Yes. The free plan includes one permanent hostname renewed annually, unlimited 30-day temporary hostnames, the Auto Setup wizard, IP monitoring and every network tool, with no credit card required. Paid plans start at $20 a year for more hostnames that stay active for as long as the plan is valid.
Do I need a static IP to use FastDDNS?
No. FastDDNS updates your hostname automatically whenever your ISP changes your IP address, usually within 60 seconds. That is exactly what Dynamic DNS is for.
Which camera brands support automatic setup?
The Auto Setup wizard covers Dahua, IMOU, Hikvision, EZVIZ, HiLook and XM/Xiongmai, including generic recorders that use port 34567. Tiandy is selectable in the brand picker, and anything else falls back to the guided manual steps.
Does the app work if my ISP uses CGNAT?
No. Behind Carrier-Grade NAT you have no real public IP, so inbound connections are blocked and Dynamic DNS cannot change that. The CGNAT Checker in the app confirms whether this is your situation; the remedy is to ask your ISP for a public IP address.
Does Auto Setup work over mobile data?
Normally no. Auto Setup connects to the camera directly, so on a job you run it with your phone on the same WiFi as the device. You can point it at a WAN IP instead, but only if that port is already reachable from the internet. Once the device is configured, managing hostnames and watching IP changes works from anywhere.
Can I use the app with routers and firewalls?
Yes. Each hostname screen carries ready-made parameter blocks you can copy into MikroTik RouterOS, DrayTek Vigor, pfSense, the Windows update client or a Linux cron job. The update endpoint is DynDNS-compatible, so any device that can make an HTTP request will work.
Do I still need to forward ports?
Yes, for anything you want to reach from the internet. DDNS only keeps the hostname pointed at your changing IP address; the router still has to let the traffic through. The one exception is Dahua Auto Register, where the device opens the connection outward instead.
Can I use one account on both Android and iOS?
Yes. Your account and hostnames are the same on every device you sign in on, and on the website as well.
Can I rename a hostname later?
No. A hostname keeps the name it was created with. If you need a different name, create a new hostname and point the device at it.
Do I need a laptop to configure cameras?
No. The whole flow runs on the phone. Auto Setup reaches the camera or recorder over the local WiFi network, so you can finish an installation on site without carrying a laptop up a ladder.
How do I get told when my IP changes?
Turn on the IP change notification switch on the hostname you care about, and the app pushes an alert when the address changes. Check that notifications are also allowed for the app in your phone's system settings.
How is this different from a web-only DDNS service?
Most DDNS providers give you a web portal and leave every device to you. This app connects to cameras over the LAN and writes their configuration itself, hands you copy-ready parameter blocks for routers and servers, and adds push notifications, IP history, port checking, CGNAT detection and network diagnostics in the same place.
