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
“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.
