“Double”. “Normal x 2” has the same video size as “Double” but of a lesser quality,
while consuming less network bandwidth.
“Power line frequency (for fluorescent light)”, the fluorescent light will flash
according to the power line frequency that depends on local utility. Change
the frequency setting to eliminate uncomfortable flash image when the light
source is only fluorescent light.
There are three dependent parameters provided for video performance
adjustment. “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.
Click on this button to pop up another window to tune
“Brightness”, “Contrast”, “Hue” and “Saturation” for video compensation. Each
field has eleven levels ranged from -5 to +5. In “Brightness” and “Contrast”
fields the value 0 indicates auto tuning. The user may press
to
fine-tune the image. When the image is O.K., press
to set the image
settings.
Click on this to recall the original settings without
incorporating the changes.
