Multicast
Multicast IP
The Multicast Menu is used for configuring the Multicast IP Address to which media
stream is delivered when a client, such as Decoder, VMS or NVR software, is
connected in 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 media protocol is
set to Multicast.
DDNS
Select the DDNS (Dynamic DNS) Server to use. Select from one of the two servers:
True DNS:
TrueDNS Service is used in this mode. Systems can be registered on
the website for TrueDNS service:
http://ns1.truecam.net
. System will have a domain
name of xxx.truecam.net style. Please refer to user guide document for True DNS
service.
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 the Current Domain entry of Network
page. E-mail setting is not mandatory.
Check IP Disable:
If ‘Check IP Disable’ is selected, it will skip to check its own
IP Address. In Fixed IP Mode, the set IP will be registered on the DDNS Server. In
DHCP Mode, dynamically assigned IP will be registered on the DDNS server. Normally,
‘Check IP Disable’ should be
unchecked
in order to obtain the Public IP in the network.
Bit Rate Control
When one or more clients are connected to the same camera, due to bandwidth
differences, some clients do not have enough bandwidth to receive the encoded stream
completely. In this case, it is possible to select the way video streaming is received:
-
Frame Drop Mode:
Encoding is performed strictly according to video settings.
When a client is connected through a network with less bandwidth, it may not receive all
the frames. Frames are dropped on the sending module if the network is bottlenecked.
-
Suppression Mode:
Encoding bit rate and frame rate are adjusted not to drop
any frames when the network bandwidths are limited to some clients. In this case, all
clients can be affected by the averaged bit rate and frame rate.
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.
