How to use Curl to download the camera configuration file
Answer
Curl is a command line HTTP client that allows you to send/receive or transfer data to and from a server. You can use this tool to send a request to the camera so that it can send you the configuration file, to do that please follow the next steps:
Step 1. Download the Curl program using the following link: https://curl.se/download.html. For convenience, you can also download the Windows binary build which can be found in the following link: https://curl.se/windows/.
Note: This tutorial will focus on Windows binary build.
Step 2. Extract the files in any desired location:
Step 3. Open the folder and go to the “bin” folder, click on the explorer bar and type “cmd.exe” to run the command prompt from this folder.
Step 4. In the command prompt type the following command:
curl.exe –anyauth –digest -u root:
Where,
–anyauth — pick any authentication method
–digest –use HTTP digest authentication
-u –user
-H –header
-L –follow redirects
camera_backup.tar.gz –camera backup file
Because the camera uses CSRF (Cross Site Request Forgery) protection, you must include the following headers:
***-H “Host:
***-H “Referer:
-H “Accept-Encoding: gzip, deflate” <
-H “Connection: Keep-Alive” <
-H “Accept: text/html, application/xhtml+xml, image/jxr, */*” <
***This data MUST be included, everything else is optional
After the command is sent you will see the following reply:
Step 4. Go to the Curl bin folder again and retrieve the configuration file.

Shut down Safe100.net and 2bthere.net servers
We are announcing that Safe100.net server for DDNS and express link 2bthere.net server will not accept any new device registrations from camera firmware x.2202.x.x and NVR firmware 4.2.x.x. With this retirement plan, the full service will be closed down by the end of 2023 and already registered devices will continue to work until that closing date.
What does close down mean?
This means that from camera firmware x.2202.x.x and NVR firmware 4.2.x.x, customers will be unable to register new devices from Safe100.net for DDNS and 2bthere.net for express link on VIVOTEK devices. All services will be closed down by December 31, 2023 and registered devices will continue to work until the closing date, December 31, 2023.
What can I do for my current devices now?
1. Check if your devices are using Safe100.net for DDNS or 2bthere.net for express link.
