Outline of Functions
20
The recorder and cameras connected to it can be operated from a
PC on the network.
Enabled functions
When monitoring images from a camera with pan and tilt function.
The recorder has two network security functions.
Limit access with user authentication/host
authentication
Turn on the user and host authentication to limit users that can
access the recorder.
Limit access by changing HTTP ports
Illegal access from port scanning is prevented by changing the
HTTP port number.
• To improve security even more
To improve network security, use a router to divide the subnet,
make two layers of IP address authentication with the recorder
and router. If the recorder is connected to a network that is not
secure, you can improve security by inserting a VPN between the
recorder and the host PC.
Connection Examples
You can improve network security by using a firewall for packet and
protocol filtering.
