Dynamic DNS is a method, protocol, or network service that provides the capability for a
networked device, such as a router or computer system using the Internet Protocol Suite, to
notify a domain name server to change, in real time (ad-hoc) the active DNS configuration of its
configured hostnames, addresses or other information stored in DNS.
Multicast

Multicast IP
The Multicast menu is used for configuring the Multicast IP Address where the
media stream is delivered when a Decoder, VMS or NVR software is connected in
the Multicast Mode. The Multicast IP Address selection range is between 224.0.0.0
and 239.255.255.255. The selection can be used only when the media protocol is
set to Multicast.
DDNS
Select DDNS (Dynamic DNS) Encoder to use. One of the two can be selected:

DynDNS
DynDNS service is used in this mode. Refer to
www.dyndns.org
for details.
ID, Password and Domain name are needed when DynDNS is set.

Vdyn
Vdyn is a DDNS service provided by Visionica (
http://visionica.com
). No further
configuration is required for using this service. It internally uses the MAC address
for the registration. When it succeeds, the domain name of the form
001C63A607EC.visionica.info is displayed on Current Domain entry of the
Network page. Email setting is not mandatory.

Check IP Disable
If
“Check IP Disable” is selected, it will skip to check it’s own IP. In
Fixed IP Mode ,
the set IP will be registered on the DDNS Encoder. In DHCP Mode , a dynamically
assigned IP will be registered on the DDNS Encoder. Normally Check IP Disable
should be unchecked in order to obtain the public IP in the network.
Bitrate Control
When more than one device is connected to the camera, due to the bandwidth
differences, some do not have enough bandwidth to receive the encoded stream
completely. In this case, it is possible to select the video options:

Frame Drop Mode: Encoding is performed strictly according to video settings.
When a device is connected through a network with less bandwidth, some frames
may be dropped.

Suppression Mode: Encoding bitrate and frame rate are adjusted so frames are
not dropped even when the network bandwidths are limited on some devices. In this
case, all devices can be affected by the averaged bitrate and frame rate.
