Multicast
: select this item to steam video once to many users. It reduces bandwidth usage
by delivering a single stream of information to multiple network recipients.
IMPORTANT:
[Multicast]
mode is available only if
[MPEG-4]
compression is selected
.
When selecting any of available transport protocols, it automatically assigns data port:
HTTP
– 80, TCP – 554. If UDP is selected, it uses strictly defined port numbers range. The port
number is assigned when the camera establishes connection with a client.
NOTE:
«HTTP»
protocol is for networks where port number restriction is used. When such a security policy is
applied, most of the nonstandard ports are closed but port 80 is often open (443, 554, etc) and is used by
this connection type.
IMPORTANT:
When
[Multicast]
mode is selected, the number of simultaneous users for viewing the image is not
limited. To enable it, go to
SETTING
– Basic – Camera – MPEG-4 – Computer view
. When using the
other modes, the maximum number of simultaneous connections is 5 (depends on network port use).

enabled, it makes the video stream from the IP camera smoother when the connection is unstable
but may cause image delays up to several seconds.
