11.13 Security

You can improve system security by setting security parameters.

11.13.1 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.
RTSP Authentication
Digest and digest/basic are supported, which means authentication information is needed when
RTSP request is sent to the device. 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, the third-party platform might not be able to log in to the
device or enable live view because of compatibility. The encrypted algorithm with high strength
is recommended.
WEB Authentication
Digest and digest/basic are supported, which means authentication information is needed when
WEB request is sent to the device. If you select digest/basic, it means the device supports digest
or basic authentication. If you select digest, the device only supports digest authentication.
WEB Digest Algorithm
MD5, SHA256 and MD5/SHA256 encrypted algorithm in WEB authentication. If you enable the
digest algorithm except for MD5, the third-party platform might not be able to log in to the
device or enable live view because of compatibility. The encrypted algorithm with high strength
is recommended.
Note
Refer to the specific content of protocol to view authentication requirements.
