„ Live-view frame rate control (Sub stream): Sets the live view frame rate of the sub stream to
help reduce the CPU usage. If you have set the live view codec to be JPEG, select the number of
frames to allow in a second. If the live view codec selected is MPEG4 or H.264, select one of the
following options:
~ Maximum Live-view Frame Rate: View the video at the maximum frame rate possible.
~ Live-view Key Frame only: You can choose to view the key frames of the videos only instead
of all frames on the live view. This option is related to the GOP setting of the IP camera. For
example, if the GOP value is set to 30, there is only one key frame among 30 frames.
„ Live-view frame rate control (Main stream): Sets the live view frame rate of the main stream
with higher resolution when On Demand function is enabled. Refer to Live-view frame rate control
above to see the options available.
„ Image Orientation: You can adjust the image orientation by selecting Normal, Horizontal Mirror,
Vertical Flip or Rotate 180.
Note:
1. Some options are not available for GV-Fisheye Cameras.
2. When CPU loading is high, selecting Live-View Key Frame Only can reduce CPU loading by
jumping from key frame to key frame and dropping the non-key frames in between. When CPU
performance is poor or live view display is slow, select Frames to keep in live view buffer to
reduce the number of frames kept in buffer and achieve a real-time appearance by dropping
frames. These settings do not affect the frame rate of the recorded videos.
