9.1.4 Security

Security Level

Specify the IP address or the network domain from which the connections to the

NVR are allowed or denied. When the connection of a host server is denied, all the

protocols of that server are not allowed to connect to the NVR.

After changing the settings, click “Apply” to save the changes. The network services

will be restarted and current connections to the NVR will be terminated.

Certificate & Private Key

The Secure Socket Layer (SSL) is a protocol for encrypted communication between

the web servers and the web browsers for secure data transfer. You can upload a

secure certificate issued by a trusted provider. After uploading a secure certificate,

users can connect to the administration interface of the NVR by SSL connection and

there will not be any alert or error message. The NVR supports X.509 certificate and

private key only.
