The installation of the DVR:
The coodinate system of DVR is shown as below:
(vertical upward direction)
Z-axis
(the side with LED)
X-axis
(the side without lock )
Y-axis
The X-axis is the front of the DVR(the side with LED). The Y-axis is the left side of the
DVR(the side without lock). And the Z-axis is the vertical upward direction.
The coodinate system of the vehicle is shown as below:
Forward
Left
DVR has various installation postures and inclinations.
For example, if the X-axis of the DVR(the front side) is consistent with the driving
direction of the vehicle, this is front installation. If the X-axis of the DVR is opposite to
the driving direction of the vehicle, this is reverse installation. And there are other
situations, just like lateral fixation.
Therefore, the installation way is needed to be set before using. Besides, there is a
situation that the DVR may be slightly tilted, so it is needed to correct the sensor at
the same time.
