[Linux-based NVR] What characters are allowed in the Backup FTP Server’s authorization?

Question

If the issue “Failed to back up recordings” occurs, please check whether the configured username and password contain any characters that are not within the supported specifications.

This article explains which characters are allowed in the Backup FTP Server’s authorization (Username and Password).

Answer

Only the following characters are allowed in the Backup FTP server’s username and password: [0–9] [a–z] [A–Z] [-].
If the password contains any characters outside this list, the NVR will not be able to recognize it, and the recording backup to the FTP server will fail.
