Streaming
Primary
,
Secondary
: The camera supports dual stream video. The secondary stream
setting is dependent on the primary stream setting. When in the dual stream mode, the
resolution and quality settings of the secondary stream will be used during event actions
(FTP upload and image attachment to Emails).
Stream
: Select the stream usage.
Live/Recording
: A
llows simultaneous live monitoring and recording. This is supported
only in one of the streams.
Live
: A
llows live monitoring only.
Compression
: Set up the compression of images for streaming. The primary stream supports
only H.264 compression and the secondary stream supports only M-JPEG compression.
Resolution
: Set the resolution of images for streaming. A maximum of 4CTF resolution is
supported, and the resolution of the secondary stream cannot exceed that of the primary stream.
Quality
: Set up the quality of images for streaming.
Bitrate Control
: Set up the bitrate control mode for the H.264 compression.
CBR
(Constant Bitrate): Persists the current bitrate regardless of the amount of motion.
VBR
(Variable Bitrate): Adjusts the bitrate dynamically based on the amount of motion.
The less motion there is, the less network congestion and the less storage capacity. The
quality may not be good comparing to the CBR mode.
Frame Rate
: Set the frame rate of images for streaming. The frame rate of the secondary
stream cannot exceed that of the primary stream.
NOTES: Simultaneous connections to the camera might cause the frame rate to decrease
due to the network bandwidth overload.
