Second encoding stream will be configured automatically to accommodate the selected
-
bandwidth limit. For example if bandwidth limit is set to 256 kbps than encoding settings of
all cameras will be set to 64 kbps for the 2
BVC playback, under low bandwidth control, streams I-Frame only to save bandwidth.
-
BVC export, under low bandwidth control, streams all I- and P-Frames. Even though this is
-
a slow process, no frames will be dropped.
BVC software version 1.4 SR5 (v1.4.464) is supporting this firmware v1.1.0
-
Important behavior:
Remote playback under bandwidth control:
-
o Recordings with 30IPS – 4CIF resolution could leads to a situation where playback is
quite difficult to stream in single speed I-Frames with bandwidth limit set to 256 kbps.
This because some I-Frames, especially with a lot of motion, are already bigger than
the 256 kbps.
In this release this is solved to start BVC playback with half-speed when the
recorder is under bandwidth control. This is the default playback speed and can
be changed by the user by pressing FWD so that playback goes to single speed.
Remote live viewing under bandwidth control:
-
o Lowest bandwidth limit can be set to 256 kbps. For live display the 2
automatically set to 64 kbps per camera. For single view the live picture quality can
be improved to select 256 kbps per camera.
