Enhance network security

It is possible to enhance the network security by dividing the subnet using a router to authenticate users twice

(by the recorder and by the router). When connecting the recorder to an unsecured network, secure the network

connection by installing a VPN (Virtual Private Network) device, etc. between the recorder and the host PC.

ed such as an intranet or Internet service provider. Refer to a network administrator for further information

about the network security.

[Connection example]

By using a firewall, etc., it is possible to use packet filtering and protocol filtering to enhance the network secu-

rity.
