Installation Guide)
Important:
• Design and enhance security countermeasures to prevent leakage of information such as image data,
authentication information (user name and password), alarm mail information, FTP server information, etc.
Perform the countermeasure such as the access restriction using the user.
• After the unit is accessed by the administrator, make sure to close the web browser for added security.
• Change the administrator password periodically for added security.
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.
Important:
• The settings for the network security vary depending on the network to which the recorder is to be connect
-
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.
