 Network load will increase if a larger video size is set or 
higher video quality and target bit rate are set, as this 
increases data size per frame. As a result, the following could 
occur:
JPEG: The frame rate may drop
H.264: Video may be temporarily disrupted
 Block noise may become noticeable if a large video size and 
low target bit rate are set. 
 The data size may increase depending on the type or 
movement of the subject. If the frame rate remains low or 
other undesirable conditions continue for a prolonged 
period, lower the video size or quality setting.

To disable Multicast, set to [0].
The TTL (Time To Live), representing the effective 
scope of multicast distribution, is decremented each 
time the signal passes through a router. When the value reaches 0, the signal can no longer be 
distributed. For example, if TTL is set to [1], multicast 
distribution is confined to the local segment only and 
cannot be distributed by the router.
RTP Streaming 1 to 5
You can make settings for each stream, RTP Streaming 1 
to RTP Streaming 5, in a 5-session RTP stream 
distribution.
(1) [Video Size]

Note
 RTP stream URL
rtsp://IP_address:port_number/rtpstream/config1(~5)=r|u|m
[=r|u|m] is optional and can be omitted. If specified, specify 
only one option.
r: Requests RTP over TCP
u: Requests RTP over UDP
m: Requests multicast
Example: RTP streaming 1 request using RTP over TCP
rtsp://192.168.100.1:554/rtpstream/config1=r
Note that the actual operation is dependent on the RTP client 
application, so the URL does not necessarily specify the 
method used for transmission.
 For H.264, the bit rate control and video quality are determined 
by the settings in [Video] (p. 62).
 Regardless of the [Server] > [Audio Server] > [Audio 
Transmission from the Camera] setting, RTP streaming audio 
will be used.
However, to use audio settings, select [Enable] for [Audio 
Transmission from the Camera] and make the settings.
 The [Access Control] > [User Authority] > [Video Distribution] 
and [Audio Distribution] settings are not used for RTP.
 RTP streaming video may not be viewable on systems using a 
proxy server or firewall. If the video cannot be viewed, 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 
several seconds until streaming ceases.

 Video and audio can be distributed to up to 30 clients. 
However, when there are many clients or they are connected 
to the camera over an SSL connection, the video frame rate 
may slow down and the sound may drop out if audio 
reception from the camera is enabled.
 The volume, sound quality, etc., may change depending on 
the characteristics of the microphone used. 
 If [Input Volume] or [Echo Canceller] settings are changed after 
setting volume detection, check the detection setting again. 
 Connect a speaker with amplifier to the camera (“Installation 
Guide” > “Audio Input/Output Terminals”). 
 If [Enable] is selected under [Echo Canceller], the sound 
quality or volume may be affected. Utilize this function as 
necessary according to the installation environment and how 
the camera is used. 
 The video and audio may not be synchronized.
 The audio may be temporarily interrupted, depending on the 
performance of the computer and the network environment.
 The audio may be interrupted if anti-virus software is 
enabled.
 Communication may be temporarily interrupted, cutting off
