Equipped security functions
The following security functions are featured in this unit.
Access restrictions by the host authentication and the user authentication

authentication to “On”. (section 11)
Access restrictions by changing the HTTP port

(section 13.1)
Access encryption by the HTTPS function
It is possible to enhance the network security by encrypting the access to units using the HTTPS

IMPORTANT
Design and enhance security countermeasures to prevent leakage of information such as image data,
authentication information (user name and password), alarm E-mail information, FTP server information,
DDNS server information, etc. Perform the countermeasure such as access restriction (using the user
authentication) or access encryption (using the HTTPS function).
After the unit is accessed by the administrator, make sure to close all the browsers for added security.
Change the administrator password periodically for added security.
