H.264(1) Configure settings using H.264(1) when using H.264 video for upload or memory card recording. H.264(2) video cannot be used for upload or memory card recording. H.264(1) video can be displayed using Admin Viewer and RM-Lite Viewer. It cannot be displayed using VB Viewer. (1) [Video Size] Select the size of the transmitted video. The video sizes that can be selected depend on the [Video Size Set] setting. (2) [Bit Rate Control] Select [Do not use bit rate control] or [Use bit rate control]. Select [Use bit rate control] when [Video Format] under [Upload] is set to [H.264(1)] or when [Video Format] under [Memory Card] is set to [H.264(1)]. (3) [Target Bit Rate (kbps)] If [Use bit rate control] is selected in (2), select a desired target bit rate from the 17 levels from [64] to [16384]. (4) [Video Quality] If [Do not use bit rate control] is selected in (2), select a desired quality from 1 to 5 (total 5 levels) for H.264 video transmission. Greater values have higher quality. (5) [Frame Rate (fps)] Select [30], [15], [10], [6], [5], [3], [2] or [1] (fps) for the frame rate of video transmitted. (6) [I Frame Interval (sec)] Select [0.5], [1], [1.5], [2], [3], [4] or [5] for the I frame interval (sec) for H.264 video. H.264(2) Refer to the settings for "H.264(1)" for details about [Video Size], [Bit Rate Control], [Target Bit Rate (kbps)], [Video Quality], [Frame Rate (fps)], and [I Frame Interval (sec)] settings. Important • When streaming two H.264 videos, setting the video size settings for H.264(1) and H.264(2) to the following combinations restricts the frame rate to a maximum of 15 fps. For all other combinations, a frame rate of up to 30 fps can be selected. H.264(1) 1920 x 1080 All sizes 1280 x 960 1280 x 720 H.264(2) All sizes 1920 x 1080 1280 x 960 1280 X 720 • When [H.264(1)] is selected for the memory card recording and upload settings, the following restrictions apply to the [H.264(1)] setting. - Only [Use bit rate control] can be selected for [Bit Rate Control]. - Only [3072] or less can be selected for [Target Bit Rate (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 RMLite Viewer. H.264 video cannot be displayed using VB Viewer. (1) [H.264(2)] Select [Enable] to distribute H.264 video using two streams. H.264(2) video can be displayed using Admin Viewer and RM-Lite Viewer. It cannot be used for upload, memory card recording, or by VB Viewer. On-screen display 62
