Multicast Transmission; Wlan - Abus CASA20550 Manuel Utilisateur

"RTP port for video" This port can be different from the default port 5558. The port number must always
be even.
"RTCP port for video" This port must be the "RTP port for video" plus 1.

6.5.7 Multicast transmission

Multicast is the message transmission from a single point to a group (also known as a multiple-point
connection). The advantage of multicast is that messages can be transmitted simultaneously to several
recipients or a closed user group without the bandwidth of the sender increasing according to the number
of recipients. When using multicast, the sender only requires the same bandwidth as a single recipient.
The packets are multiplied on each network distributor (switch, router).
Multicast allows data to be sent efficiently to many recipients at the same time in IP networks. This is made
with a special multicast address. In IPv4, the address range 224.0.0.0 to 239.255.255.255 is reserved for
this purpose.
The following multicast settings can be configured for streams 1 - 4 in the network camera.
Enable "Always multicast" to use multicast.
"Multicast group address" Specifies a group of IP hosts which belong to this group
"Multicast video port" This port can be different from the default port 5560. The port number must always
be even.
"Multicast RTCP video port" This port must be the "Multicast video port" plus 1.
"Multicast TTL" Time to Live
If you are setting up port forwarding in a router, all ports should always be forwarded this way
(RTSP + HTTP). This is imperative for successful communication.

7. WLAN

You can configure the WLAN settings for the network camera here. Enter the WLAN access data and press
"Save". A progress bar will be displayed while the configuration is being saved. The status LED changes
from green to red during this process, and then back to green. Wait until this process is complete and the
camera website has been refreshed.
After completing the WLAN configuration, the camera
must be restarted with the network cable
disconnected for the change from wired to wireless
mode.
The network camera supports the WLAN standard 802.11b/g/n. The camera automatically
detects which WLAN standard is being used. In order to benefit from the high data transfer
