I. Authentication
You can improve network access security by setting RTSP and WEB authentication.
Go to Configuration → System → Security → Authentication to choose authentication protocol and method according to your needs.

If you select digest/basic, it means the device supports digest or basic authentication. If you select digest, the device only supports
digest authentication.
RTSP Digest Algorithm
MD5, SHA256 and MD5/SHA256 encrypted algorithm in RTSP authentication. If you enable the digest algorithm except for MD5,
