Kilobytes and Gigabytes are units of storage:

1GB = 1024 Megabytes (MB)

1MB = 1024 Kilobytes (KB)

With analogue recording, the image quality is dependent on the type of VCR being used; VHS or S-VHS. The unit

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.

Note: 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.

Using a larger image size will ll 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.

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 gure and is not effected by how many cameras are connected. 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

The unit calculates the recording time automatically when the record rate and image quality are entered.
