2.1.2 G sensor
The accelerometric sensor continuously generates three analog signals relating to the
acceleration values detected on the X, Y and Z axis.
X axis: It is aligned with the vehicle travel direction
Y: It is perpendicular to the axis X and is associated lateral acceleration
Z axis: is orthogonal to the axes X, Y and is associated to the vertical axis.
The acceleration values on the three axes acquired are included in the field:
X: 0.78 ~ 1.76GY: 0.78 ~ 1.76GZ: 0.98 ~ 1.95G
2.1.3 GPS Sensor
The GPS satellites 20 is integrated in the system and is able to acquire the position coordinates and
time of the system.
OCTOBOX 4V VEDR
uses the position information and time to determine the average speed and
also to upgrade the system real-time clock integrated.
GPS signal reception depends on environmental factors that determine the visibility of the satellites.
The status of GPS signal reception is notified by the alarm LED 'GPS' on the rear of the camera body.
2.1.4 Real Time Clock
The 20 satellites GPS is integrated in the system and is able to acquire the position coordinates
and time of the system.
OCTOBOX 4V VEDR
uses the position informations and time to calculate the average speed
and also to upgrade the system real-time clock integrated.
The GPS signal reception depends on environmental factors that determine the visibility of the
satellites.
The status of GPS signal reception is notified by the alarm LED 'GPS' on the rear of the camera
body.
2.1.5 Backup Battery
In case of serious accidents there is the possibility that the event determines the interruption of
OctoBox Powerline supply.
