5.5 DDNS configuration
In picture 3，router-1 obtain wide area network IP address through ADSL，the IP
address is dynamic，we could not know the real-time IP address of the device from
internet，therefore，we need to obtain the address through DDNS server in internet，
camera-1 will send message to the DDNS server for each defined-interval time，the
DDNS server analyze the IP address of router-1 it connected，then we can obtain the
IP address from DDNS server. Therefore，the domain name stands for the dynamic IP
address， if the device can not be found by IP address，the domain name is not
available.
