Quality
(10/20/30/40/50/60/70/80/90/100): You can adjust the recording quality. The
higher the number, the better the quality. However, the higher quality setting will consume
more hard disk space.

Sensitivity
(10/20/30/40/50/60/70/80/90/100): You can set the sensitivity of motion

prevent any data loss. However, in some special conditions, the system continues to record
even when no motion has occurred. This will result in a considerable amount of useless
data being recorded. In such a case, it is recommended to lower the sensitivity setting to
avoid wasting hard disk
