Precautions
Please read carefully before use
1. In a logistics park trailer scene, a radar has a blind spot,
thus one radar is needed above and below to ensure vehicle passage.
The radar installation should not be level with the pole.
Installation height for cars: 60cm-65cm from the bottom of the
radar to the driving surface. Installation height for trailers:
100cm-110cm from the bottom of the radar to the driving surface.
2. If the radar's front is obstructed by license plate recognition
or other objects, it must be installed on a separate pole to avoid
these obstructions.
3. In areas with many ground covers or large metal plates, usage is
not recommended. Small area covers or tracks can be used
(confirmation with manufacturer's technical staff required).
4. Radar is not recommended in sharp turn scenarios, or in mixed
pedestrian and vehicle roads as pedestrians can interfere with the
radar.
5. In scenarios where vehicles enter and exit simultaneously, it's
required that each vehicle corresponds to a single pole; do not
follow vehicles or linger under arm.
6. For advertisement arm, barrier arm, or fold arm, the best
installation position for the radar is facing the direction of
incoming vehicles. If not possible, each vehicle should correspond
to a single pole and avoid lingering under arm.
7. Do not power the radar using a 12V output from a barrier gate
motherboard; an independent 12V 1A~2A power supply is needed.
8. When the pole's lowering angle exceeds 45 degrees, the radar's
sensitivity to detecting intruding objects will decrease.
Installation Instructions (Schematic)
Install the radar vertically on the barrier box with the indicator
light facing upwards.
Installation height for cars: 60cm-65cm from the bottom of the
radar to the ground.
Installation height for large vehicles: 100cm-110cm from the bottom
of the radar to the ground.
Distance between the radar and the barrier arm: 20cm.
