Video and audio server ports only need be changed if a network has security or
operational restrictions using these ports. In most cases, the RTP/RTCP video
and audio should use the default values.
While the RTP/RTCP audio/video ports by default are 6002-6005, this represents
the starting point for client connections. If 1 client is connected, then this
connection would use 6002-6005, but a 2
nd
connection would then use 6006-6009.
This may require proper router configuration if using the web UI outside of a
LAN.
Maximum Viewers refers to concurrent uses. Connections beyond this value will
receive an error upon connection.
Multicasting allows sending a message or data to a group via a single message.
The multicasting parameters are only for configuring a camera to use
multicasting. A networking environment that supports multicasting must be
setup which is beyond the scope of this document.
3.9 Network – DDNS
DDNS is used to map a dynamically assigned IP address (a device using DHCP)
with a hostname.
NOTE
: Certain network configuration will likely be required (i.e. mapping the IP
address recognized by the DDNS service to the IP camera) to implement DDNS.
Therefore, the network administrator will likely need to be consulted.
If the IP camera uses DHCP, a DDNS service can provide a hostname for use
with the IP camera.
Registration with one of the DDNS service providers (ddns.nu, dyndns.org) is
required for use of this feature.
