Motion detection recording and sensitivity level setting: When there is an object
moving and its movement amplitude exceeds the preset motion detection sensitivity
level, Motion detection recording will be triggered. For this kind of event recording, the
pre-record time will be set as 15s and the post-event time is configured by Event
Duration above.
Total video file length = pre-recording file length (default time 15s) + file length
(configured by Event Duration).
If motion detection is off, event recording will not be triggered. Motion detection
sensitivity can be set to two levels, low / high. Motion detection recording is on when
low / high is selected. Motion detection recording is off when OFF is selected.
8.9 G-sensor Sensitivity
G-sensor Event Detection settings:
Through the nine-axis G-sensor, DVR can measure the acceleration and angular
velocity of the vehicle when it goes forward or turns. If the specific threshold is
exceeded continuously within a certain period of time, the corresbonding alarm will be
triggered and recorded.
The threshold and duration time of triggering alarm can be configured according to
different usage scenarios. The shorter the duration time is, the smaller the threshold
is, the higher the sensitivity of triggering alarm will be.
Go to “Record - G-sensor Sensitivity-Setup” page. The interface is shown as follows.
G-sensor triggered recording and sensitivity level setting: When the acceleration
or gyroscope of the G-sensor reaches the preset sensitivity value, G-sensor
recording will be triggered. For this kind of event record or alarm record, the
pre-record time will be set as 15s and the post-event time is congured by Event
Duration above.
Total video le length = pre-recording le length (xed 15s) + le length
(congured by Event Duration).
If G-sensor triggered recording is o, event recording will not be triggered.
G-sensor sensitivity can be set to two levels, low / high. G-sensor triggered
recording is on when low / high is selected. G-sensor triggered recording is o
when OFF is selected.
