The user must be logged in as Administrator in order to
make changes in the Stream 1 tab.
•
Click the Setup button.
•
Click the Configuration button.
•
Click the Stream 1 tab.
Use The Stream 1 tab to set up the transport mode and
parameters of the video stream one.
Encoding:
Stream one is available in H.264 or MJPG formats.
Video Format:
Choose resolution for stream 1 from drop-down menu.
The Bit rate can be selected at various levels between
256,000 and 8,000,000 bits per second (bps). Choose
4,000,000 for optimal bandwidth and video quality.
Frame rate can be selected from the drop-down menu.
NOTE: SD (standard definition) cameras must have both streams enabled. Stream 1 must use a frame rate
of 30fps (frame per second).
Streamimg:
Four supported transport modes can be used for stream one: unicast, multicast, RTP/TCP, and RTP/HTTP/
TCP. Selecting Multicast allows you to specify a multicast address to use. In all cases the packet size to use
can be specified as 550, 1400 or 8192 bytes.
Transport Mode: Choose from the drop down menu:
•
Unicast RTP/RTSP broadcasting: For video on demand between a single sender and a single re-
ceiver – and if the system does not have multicast capabilities (see Note 1 and Note 2).
•
Multicast broadcasting: For a large simultaneous number of viewers and for the most efficient
usage of bandwidth.
•
RTP/TCP: Use RTSP Interleaved method to traverse firewalls.
•
RTP/HTTP/TCP: Use HTTP tunneling method to traverse firewalls.
NOTE 1: Multicast requires a custom configuration of most routers. It is not possible to multicast
over the Internet.
NOTE 2: Only 8 simultaneous connections are allowed for a unicast broadcasting.
Default Multicast address: 232.0.0.52
Multicast Port: This parameter sets the destination multicast port for stream 2 using the RTP or M2TS trans-
port over UDP. Value: 1-65535. Default: 18000.
Max Packet Size: The factory default is 1400. For 10BASE-T networks use 550, 100BASE-T use 1400, and
1000BASE-T (GigE) with jumbo frame support use 8192 bytes.
RTSP Timeout: Sets the value of RTSP timeout in seconds. If a RTSP client does not send a keep alive
message during this interval, the RTSP server would disconnect the client. Use a value in the range 5 to
300 secs. 60 seconds is a recommended number.
Multicast TTL: Set the TTL (Time-to-live) for the multicast UDP packets sent using RTP or M2TS transport.
This value is applied to both streams. Value: any value in the range 1 to 255. Default value is 12 hops.
