Resolution
The resolution denes the size of the saved images. The entries are made using H.261/CIF
(Common Intermediate Format) and dene length x width in pixels.
Frame Rate
The frame rate denes the number of individual images that are saved every second. The
higher the frame rate the more uid 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.
