The entries are made using H.261/CIF(Common Intermediate Format) and define length x width in pixels.Frame RateThe frame rate defines the number of individual images that are saved every second. Thehigher the frame rate the more fluid the playback.Bit RateThe bit rate is a measure of the degree of compression of video data. It thus has a directimpact on the image quality of the recordings.A low bit rate stands for a high degree of compression with a relatively small volume ofdata. But the image quality also is poor. A high bit rate stands for a low degree of compres-sion with a relatively large volume of data. The Image quality is very good.DeinterlaceThis function can be activated to increase the picture quality. It reduces the interlace effectin images with fast movements.Whether and to what extent the image quality can be improved depends on a large numberof variables. We recommend a check of the image quality after the recording has beenconfigured.6.5.1.2 Dallmeier IP and HD cameras¾ Ensure that the Expert Mode option is activated.¾ Select the Quality tab.¾ Observe the explanations given below.
