Intra Frame Period: In the H.264 mode, if there is little motion and most of the video content does
not change from frame to frame, the H.264 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.
Maximum frame rate: Click on the drop-down list to choose the frame rates of “30FPS”, “15FPS”,
“7FPS”, “4FPS” and “1FPS” in all resolution.
Video quality: Selects the image quality level of JPEG images captured from “Highest”,
“High”, “Medium”, “Low” and “Lowest”.
Selects the image quality level of H.264 images captured from “Constant bit”
(4M, 2M, 1M, 512K, 256K, 200K, 128K and 64K) or “Fixed Quality“ (Highest,
High, Medium, Low and Lowest).
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.
