For example, if TTL is set to [1], multicast transmission is confined to the local segment only and cannot pass through the
router to be transmitted.
RTP Stream 1 to 5
Set each stream for transmission of the RTP stream 1 to 5 (video stream 1 to 4, and digital PTZ) on a per-stream basis.
[Video Type]
[Video Compression Method] and [Video Size] are displayed as set in [Video] > [Video].
[Multicast Address]
Enter the multicast address for RTP streaming as follows.
IPv4: Range from 224.0.0.0 to 239.255.255.255.
IPv6: Address starting with ff00::/8
Enter [0.0.0.0] for IPv4 and [::0(::)] for IPv6 to disable multicast.
[Multicast Port]
Enter the multicast port number for RTP streaming.
If set to [0], multicast is disabled.
[Multicast TTL]
Enter the effective range for multicast transmission of RTP streaming.
If set to [0], multicast is disabled.
The TTL (Time To Live), representing the effective range for multicast transmission, is decremented each time the signal
passes through a router. When the value reaches 0, the signal can no longer pass through the router and be transmitted.
For example, if TTL is set to [1], multicast transmission is confined to the local segment only and cannot pass through the
router to be transmitted.
[Audio Transmission]
Select whether to use audio transmission for RTP streaming.
[Enable] cannot be selected if [Audio] > [Audio] > [General Audio] > [Audio Input] is set to [Disable].
• RTP Streaming URL
rtsp://IP Address:Port Number/rtpstream/config1(to 5)=m
[=m] is the multicast request and can be omitted.
Note that since the actual operation is dependent on the RTP client application, the specified method is not necessarily used for
transmission.
• When H.264/H.265 video is selected, for bit rate control and video quality, settings respectively set in [Video] > [Video] > [Stream 1] or
[Stream 2] (P. 58) are used.
• The [Video Distribution] and [Audio Distribution] settings in [Security] > [User Management] > [User Authority] are not used for RTP.
• RTP streaming video may not be displayed in an environment using a proxy server or firewall. If this occurs, contact the system
administrator.
• If Host Access Restrictions are applied to a client while it is streaming using RTP over UDP, it may take from a few to tens of seconds
until streaming ceases.
• Regardless of the [Audio] > [Audio] > [Audio Server] > [Audio Transmission from the Camera] setting, audio RTP streaming will be
performed.
