Network security function
The 2 network security function are provided to the recorder.
Access restriction by the user authentication and the host authentication
When "On" is selected for the user authentication and the host authentication, users will be restricted to access the recorder.
Access restriction by changing the HTTP port number
By changing the HTTP port number, it is possible to prevent illegal access such as a port scanning, etc.
• To enhance the network security
Divide the subnet into several subnets using a router, and dualize the authentication using the authentication functions of the rout-
er and the recorder. If connecting the recorder to a network that is not secure, enhance the security by installing a VPN between
the recorder and a host PC, or other security measurement.
Important:
• The network settings of the recorder will be different depending on the settings of the LAN or the Internet service provider to
which the recorder is to be connected. Ask your network administrator for the network security.
