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 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 three options for two 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.

"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 ranging from -5 to +5. 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.
