RTSP:
Settings for RTSP transmission.
RTSP port:
The standard port for RTSP transmission is 554. Alternatively, this port can have a
value of 1024-65535. If several IP cameras are located in the same subnetwork, then
each camera should have their own unique RTSP port.
RTP:
Settings for the RTP transmission (Real Time Protocol).
Unicast streaming:
When using Unicast streaming, the video and audio files are transmitted to a recipient
who requested the data.
Port range:
The standard port range for RTP Unicast streaming is 5000-7999. Alternatively, the
port range can have a value of 1027-65535.
Multicast streaming:
Multicast relates to a 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.
Multicast address:
Entry of the Multicast server address.
Image Size:
Select from the following image resolutions (pixels): 1280x1024, 1280x720,
640x480, 320x240.
Frame rate:
Specifies the frame rate in frames per second (fps).
Quality:
Settings for the quality of the video stream.
Auto:
The video quality is adjusted automatically according to the available network
bandwidth.
Fixed quality:
The video quality is set to a fixed level. The network bandwidth requirements
can rise or fall according to demand.
Fixed bitrate:
The bit rate of the video stream is set to a fixed level. The video quality can
vary according to the level of activity.
IP interval:
This parameter specifies the full-screen interval. The full-screen interval (IP
interval) specifies how often a full-screen image is contained in the video
stream (differential image procedure, MPEG-4). A lower value requires more
network bandwidth, but leads to an improvement in image quality.
