Ackton P5000 - Manual (Page 11)

Due to the obstacle's position, angle or size, the reflected
signal may not reach the receiving sensor. Complex reflec-
tions may also occur in a complex environment causing
inaccurate detection. See examples 1, 2, 3, 4, 5 and 6.
Low lying obstacle
Complex environment: B will be
detected but A cannot be detected.
Distance A will be detected first, then
distance B, as the car reverses.
However, as the car nears, A will fall
into the sensor's blind zone. In such
cases, the system will misjudge B as
the closest distance.
When the car approaches a glass wall
(or any other smooth surface) almost
paralleled to the body of the car, the
wall may not be detected as most of
the signal is reflected away.
When the car approaches a smooth
slope, the slope may not be detected.
The system may not detect a small,
r ound, smooth pole.
Obstacles may not be detected
