DDNS server administrated
by Samsung Electronics.
Use External DDNS: Select if you wish to use a
DDNS server other than the
one offered by Samsung
Electronics.

If Samsung DDNS (websamsung.net) is
selected, a DDNS address will be automatically
allocated using the physical address of the
ethernet card attached to the main unit. With
an Ethernet card whose MAC address is
00-0c-8c-ab-cd-ef, for example, the domain
gets automatically assigned as aabcdef.
websamsung.net. Here, abcdef designates the
last six digits of the card's MAC address and
the “a” denotes the DVR (mode: SPR-9x16)
identifi cation code.

When confi guring an external DDNS (dyndns.
com, no-ip.com, changeip.com), it takes
approximately 30 to 60 seconds to update the
URL IP to the DNS.

If you are accessing a network directly via an IP
router, you must designate the DDNS network
port under the IP router’s setup menu.
If you are receiving dynamic IP allocation for your DVR
unit using your IP router’s DHCP feature, you must
designate a port for the received IP under the IP router
’s setup menu. For applications using an IP router,
Samsung Electronics recommends that instead
of using the DHCP feature you fi rst designate the
allocated IP and port number under the router’s setup
menu, set the main unit’s connection mode as fi xed
IP, and then directly enter the designated IP on the
IP router. Please refer to your IP router’s user manual
or contact the router manufacturer for instructions on
router confi guration.
