Quick Install - Dedicated Micros digital sprite 2 Setup Manual

With analogue recording, the image quality is dependent on the type of VCR
being used; VHS or S-VHS. Digital Sprite 2 allows the image quality to be
altered by adjusting the image size, for example, low quality is 14KB, medium
is 18KB, and 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.
Standard 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 16
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
Hard disk capacity
Using a larger hard disk will allow image quality, recording rate, or recording
time to be increased. For example, an 80GB disk can record for 8 days at the
default settings (24-hour time-lapse mode at Medium quality).
Tip: As a rule-of-thumb recording at the default settings* will use 10GB of
storage per day, i.e. an 80GB unit will record for 8 days.
Calculating recording time
Digital Sprite 2 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:

* 24-hour time-lapse mode, 6PPS, and medium quality images, 18KB.
