    (kbps)].
    - Only one of [0.5], [1], and [1.5] can be selected for [I 
    Frame Interval (sec)].
     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.
     The included RM-Lite cannot record H.264 video.
     H.264 video can be displayed using Admin Viewer and RM-
    Lite Viewer. H.264 video cannot be displayed using VB 
    Viewer.

    Set the multicast address for audio transmission in the 
    range 224.0.0.0 to 239.255.255.255 (IPv4) or an 
    address beginning with ff00::/8 (IPv6).
    To disable Multicast, set to [0.0.0.0] (IPv4) or [::0(::)] 
    (IPv6).
    (2) [Multicast Port]
    Set the multicast port number for audio transmission 
    to an even number in the range 1024 to 65534.
    To disable Multicast, set to [0].
    (3) [Multicast TTL]
    Set the effective scope of multicast distribution 
    between 0 and 255.
    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]

    size of the RTP stream.
    The video sizes for JPEG will vary depending on the 
    [Video Size Set] configured in [Video] > [All Videos] 
    (p. 61). The video sizes for H.264 will be determined 
    according to the [H.264(1)] and [H.264(2)] settings 
    configured in [Video].
    In addition, [H.264(1)] and [H.264(2)] cannot be set 
    for multiple RTP streams.
    (2) [Frame Rate]
    Set the frame rate if RTP streaming JPEG video. For 
    H.264, the frame rate is determined by the [Video] > 
    [H.264(1)] or [H.264(2)] > [Frame Rate] setting 
    (p. 62).
    (3) [Multicast Address]
    Set the multicast address for RTP streaming in the 
    range 224.0.0.0 to 239.255.255.255 (IPv4) or an 
    address beginning with ff00::/8 (IPv6).
    To disable Multicast, set to [0.0.0.0] (IPv4) or [::0(::)] 
    (IPv6).
    (4) [Multicast Port]
    Set the multicast port number for RTP streaming to an 
    even number in the range 1024 to 65534.
    To disable Multicast, set to [0].
    (5) [Multicast TTL]
    Set the effective scope of multicast distribution for 
    RTP streaming between 0 and 255.
    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.
    (6) [Audio Transmission]
    Set RTP streaming audio transmission to [Disable] or 
    [Enable].
    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.

    Important
     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 
    the audio, if the LAN cable is unplugged and plugged in 
    again. If this occurs, reconnect from the Viewer.
    Important
    If the setting of [HTTP Port] or [HTTPS Port] is changed, the 
    camera may become inaccessible from the active web 
    browser. Check beforehand the precautions in “Important” in 
    “[Reboot Item] Setting Items Requiring Rebooting” (p. 87).
