● After accessing this product as an administrator, be sure to close all web browsers to strengthen security.


● Do not reuse user names (administrator names) and passwords for other recorders or products.

Enhance network security

Encrypt the communication between the recorder and camera and enhance the network security. The registration of the secure communication license allows you to encryption of the recorded data will further enhance the security.
Contact your dealer for Secure Communication Kit. 
In addition, network security can be enhanced by the following measures.
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 connected 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 security.
