Description of function keys:
Mode:
Choose the video format from “JPEG” or “MPEG4”. It can be either JPEG
or MPEG4. In JPEG mode, the video frames are independent. However,
MPEG4 consumes much less network bandwidth than JPEG.
Frame size:
This option allows the user to choose the video resolution of the camera
between “1280x960”, “1280x720“, “640x480”, “320x240” and
“160x120”.
Maximum frame rate:
Click on the drop-down list to choose the frame rates of “30FPS”,
“15FPS”, “7FPS”, “4FPS” and “1FPS”.
Video quality:
Selects the image quality level of JPEG images captured from
“Excellent”, “Detailed”, “Medium”, “Good” and “Standard”.
Selects the image quality level of MPEG4 images captured from
“Constant bit” (8M, 6M, 4M, 2M, 1M, 512K, 256K, 200K, 128K and 64K)
or “Fixed Quality“ (Highest, High, Medium, Low and Lowest).
Intra Frame Period:
In the MPEG4 mode, if there is little motion and most of the video
content does not change from frame to frame, the MPEG4 encoding
can compress the video by intra-frame way to keep the quality from
loss.
You can set the desired time period to use intra-frame compression.
Audio Settings:
You can use the option to switch the external microphone on/off or
adjust the volume.
Encoding:
Click on the drop-down list to choose the audio encoding of “G.711” and
“G.726”. G.726 offers quality nearly identical to G.711, but it uses only
half the bandwidth.
