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 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” is the quarter size of “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.
