3.8 Network – Streaming
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.
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.
