For your privacy and to better protect your system against security risks, we
strongly recommend the use of strong passwords for all functions and
network devices. The password should be something of your own choosing
(using a minimum of 8 characters, including upper case letters, lower case
letters, numbers and special characters) in order to increase the security of
your product.

Note: Refer to Appendix 2 for detailed information about port mapping.

Connecting the network camera via a modem
Purpose:
This camera supports the PPPoE auto dial-up function. The camera gets a public
IP address by ADSL dial-up after the camera is connected to a modem. You
need to configure the PPPoE parameters of the network camera. Refer to
Section 6.3.3 Configuring PPPoE Settings for detailed configuration.
Figure 2-6 Accessing the Camera with Dynamic IP
Note: The obtained IP address is dynamically assigned via PPPoE, so the IP
address always changes after rebooting the camera. To solve the inconvenience
of the dynamic IP, you need to get a domain name from the DDNS provider (E.g.
DynDns.com). Please follow the steps below for normal domain name
resolution and private domain name resolution to solve the problem.
