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.

Important
• 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 RM-
Lite Viewer. H.264 video cannot be displayed using VB
Viewer.
