The Device is Not Registered in the DDNS Error

If you encounter the issue of “the Device is not registered in the DDNS” when you try to connect to you CCTV cameras using the mobile app ivms-4500, here is the solution to it:

1) While you are in the same network of your CCTV system, open your browser (Firefox recommended) from your computer (NOT mobile phone).

2) Type the URL address of your NVR/DVR, and login the system (if you are not sure how to do this, please refer to our remote support to get help from us)

3) Go to “Configuration” -> “Network” -> “Basic Settings” -> “TCP/IP”. Make sure the preferred and alternate DNS server is set to “” and “” respectively. Click “Save” when you are done.

4) Go to “Configuration” -> “Network” -> “Basic Settings” -> “DDNS”. Select “Asia” in Area (or Locality in some system). Select “Singapore” in Country and “Save”

The issue of “Device not registered” should be resolved by now.
