■Network Security
●WJ-HD220 Security Function
Host/User Authentication
Access can be limited by setting the authentication function to ON in the menu setup. Note: Be sure to change the password from the default setting "admin" to your own.
Changing the HTTP Port Number
Changing the port number will limit unauthorized accesses such as port scanning.
●For More Security
Using Routers
Authentication is doubled by use of routers: divid- ing into subnet, and verifying IP addresses by the recorder and the routers.
