PRE- ALARM:
This option determines that images prior to an alarm will be recorded in the hard-disk drive. When an
alarm is triggered the device will record the image prior to the alarm for 5 seconds. (
10 frames/sec
)

NOTE: If the device is already under recording mode before an alarm, the pre-alarm recording
will not take effect.
MOTION SETTING:
The motion detection function is convenient for users lacking an alarm trigger input, but can also be
used with an alarm trigger input. If this function is enabled, any movement will trigger the alarm
recording just like an outside trigger signal. Before using the motion detection function, please turn
the
CH1/ CH2/ CH3/ CH4
options to
ON
, and set the
SENSITIVITY
(1 ~ 5 ) to a suitable value.
