Video codec 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 date and time of Network Camera

that is maintained by a built-in real-time clock.

“Color”, select either one for color or monochrome video display.

"Size", there are three options for two video sizes. “Half” has quarter size of

“Normal”. “Half x 2” has the same video size as “Normal” but has worse quality.

However it consumes 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", it limits the maximal refresh frame rate that can be

combined with the "Video quality control" to optimize the bandwidth utilization and

video quality. If users want 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 in order to send maximal frames within the limited bandwidth when images

change drastically. Consequently to ensure the video detail (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 both if Network Camera is installed

upside down.

“White balance”, choose the suitable option for best color temperature.

, click 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. The user may press

to fine-tune the image. When

the image is O.K., press

to memorize the image settings. can be clicked to

recall the original settings without changes.
