TH4 Advanced Configuration
G Sensor settings recomendation
We recommend the default G-Sensor settings for large bus movement detection.
Smaller vehicles may require lower thresholds - some experimentation may be necessary to define the optimal configu
-
ration for each vehicle type. If thresholds are set too low, they may generate many alarms.
ITEM
DESCRIPTION
VALUE [DEFAULT]
Axis
X - forward/back axis
Y - left/Right axis
Z - vertical axis
Vector - combination of X and Y axes (to capture driver behavior incidents)
Accident - combination of X and Y axes (higher threshold settings, to
capture vehicle accidents)
n/a
Current
The current (live) values measured by the G Sensor (display only)
n/a
Threshold
Set from 0G to 6.0G. This value configures the threshold level. Any value
beyond the threshold triggers the output, as configured in the Output field.
X = [+/- 2.00]
Y = [+/- 2.00]
Z = [+/- 3.00]
V = [+ 3.00]
A = [+ 5.00]
Output
If the specified G Sensor threshold value is exceeded, the DVR triggers the
selected output (DVR log entry, Signal, or Alarm).

Peak
Use the observed peak values to refine threshold settings.
Peak values reflect detected G Sensor levels for axis, Vector, and Accident
activity.
