DDNS
DDNS is a service that maps Internet domain
names to IP addresses. DDNS serves a similar
purpose to DNS: DDNS allows anyone hosting a
Web or FTP server to advertise a public name to
prospective users.
Unlike DNS that only works with static IP
addresses, DDNS works with dynamic IP
addresses, such as those assigned by an ISP or
other DHCP server.
What this means is that the DVR does not need a
Static IP address to be available for viewing
remotely over the World Wide Web.
IP Set
When a fixed IP address is being used, the Use
Dynamic IP should be set to NO.
The IP Address, Gateway and Subnet Mask need
to be set, these will generally be given by the
Network Manager.
DSL refers to all types of Digital Subscriber Line
such as ADSL and SDSL.
The DVR Port and WEB Port can both be
changed if required, default are 2000, and 80
respectively.
NTP Setup

clock synchronised with an External clock.
