Resolution
The resolution defines the size of the saved images. The entries are made using H.261/CIF
(Common Intermediate Format) and define length x width in pixels.
Frame Rate
The frame rate defines the number of individual images that are saved every second. The
higher the frame rate the more fluid the playback.
Bit Rate
The bit rate is a measure of the degree of compression of video data. It thus has a direct
impact on the image quality of the recordings.
A low bit rate stands for a high degree of compression with a relatively small volume of data.
But the image quality also is poor. A high bit rate stands for a low degree of compression
with a relatively large volume of data. The Image quality is very good.
