Quick Install - Dedicated Micros D4 Anleitung

With analogue recording, the image quality is dependent on the type of VCR
being used; VHS or S-VHS. D4 allows the image quality to be altered by
adjusting the image size, for example, LOW quality is 14KB, MEDium is 18KB,
and greater than HIGH is 25KB*.
Using a larger image size will fill the hard disk faster than a smaller image size,
as more space is required to store it. To achieve the same amount of recording
time when a larger image size is used requires the record rate (PPS) to be
reduced.
* Note that as for all digital recording, image quality can vary for different scene types, MEDium
quality may be 18KB in one scene, but it may be 30KB or more to get the same quality in a scene
with more detail.
Record Rate
The record rate is the amount of pictures recorded to disk in a second, or
pictures per second (PPS). This is a system wide figure, so whether 1 or 4
cameras are recorded, the record rate remains the same. The update rate per
camera can be worked out using the record rate:
Update rate = No. of cameras
Record rate
A table of common record rates can be found in Appendix 1.
Calculating Recording Time
D4 calculates the recording time automatically when the record rate and image
quality are entered. Alternatively, an interactive record calculator is available for
download from our web site:
