IP DVR SERVER
USER MANUAL
17
Motion JPEG Stream
Operation
Either activate or deactivate the specific stream. Primary Stream is
always active. If user is not using Secondary Stream, it’s always a good
idea to deactivate it. For example, if user is running on 320x240 Single
Resolution (only Primary Stream is active), IP DVR SERVER will perform
at 30fps; however, if running on Dual Resolution (activating both
Primary Stream and Secondary Stream), frame rate will be less than
30fps. (Please refer to M-JPEG Frame Rate on bottom of this chart for
further explanation).
Operation will also have effects on other functions as well. For
example, if you choose to run deactivate stream in “Record” or “Event,”
that specific function won’t perform normally.
Resolution
Choose size of image per stream.
Quality
Configure the quality of each stream.
Frame rate
Configure the maximum frame rate per second. Depending on usage of
Secondary Stream and Resolution configuration, maximum frame rate
might differ from the set value.
In case of Single Resolution, 640x480 is maxed at 15fps and 320x240
is maxed at 30fps. However, if running a Dual Resolution, two different
streams are activated concurrently, thus, resulting in lower maximum
frame rate.

Images of demo site from Linudix’s homepage is based on ActiveX and running only on Primary
Stream. However, user is able to choose between Primary Stream and Secondary Stream on the
integrated application, using our CGI/API.
