Audio/Video Codec Parameters
Audio Parameters
“Mute” Check the option will make the Network Camera reboot to force all the connection
using HTTP mode to view the video, therefore no audio can be heard at any client side.
“Improve audio quality in low bandwidth environment” Check the option will make the
Network Camera reboot to make communication of audio channel more efficient.
“Audio Source” The selection can be “Internal microphone” or “External
microphone”. When “External microphone” is selected, the red light of the Network
Camera will blink once a second.
Video Parameters
“Text on video” The text will be displayed in the black bar above the video window with a
timestamp. The timestamp is captured from the date and time of the Network Camera that
is maintained by a built-in real-time clock.
“Color” Select either for color or monochrome video display.
"Size" There are five options for three video sizes. “Half” is the quarter size of “Normal”.
“Half x 2” has the same video size as “Normal” but of a lesser quality, while consuming
less network bandwidth. “Normal x 2” will do digital zoom with factor of 200% for both
width and height of the video, and “Double” will have the Network Camera sending
704x480(NTSC)/704x576(PAL) size video to every connections with the maximum
frame-rate of 10.
"Maximum frame rate" This limits the maximal refresh frame rate, which can be combined
with the "Video quality control" to optimize bandwidth utilization and video quality. If the
User wants to fix the bandwidth utilization regardless of the video quality, choose "Fix bit
rate" and select the desired bandwidth. The video quality may be poor due to the sending
of maximal frame rate within the limited bandwidth when images are moving rapidly.
Consequently, to ensure detailed video quality (quantization rate) regardless of the network,
it will utilize more bandwidth to send the maximal frames when images change drastically.
"Flip" Vertically rotate the video.
"Mirror" Horizontally rotate the video. Check options both if the Network Camera is
installed upside down.
“White balance” Adjust the value for best color temperature.
