FAQ
Problem
Solution
No response after the
Radar is powered on.
When the Radar is powered on, the power indicator light will
glow. If not, check whether the power cord is firmly connected.
Check whether the polarity of the power cord is correct, the
supply current and voltage conform to the Radar label, and
PoE (802.3at) power supply is normal.
Power supply is normal but
the Radar cannot detect
objects.
Make sure that radar's installation direction is correct. See "2.2
Detection Range" and "2.4 Installation".
Check whether the network port is connected.
No object is found in the
detection area but there are
detection signals.
Check if the Radar installation direction faces the detection
region, and there is no intense electromagnetic equipment in
the detection region to interfere the Radar.
The pole with the Radar installed on is not swaying.
No weed or swaying branch in the detection region. If any,
prune them regularly or draw a shield area around them.
Does a target behind a solid
object can be detected by
the Radar?
Electromagnetic wave of the Radar cannot penetrate objects such
as cement, rocks, glasses, and metals. If any, a blind zone will be
formed behind these objects.
Is radar's detection range a
sector?
No. The detection distance in front of the Radar is farther than the
sector shows, but for the margin area, it is shorter than the sector
shows.
Targets close to the Radar
cannot be detected.
Due to limitations of installation height and horizontal detection
angles of the Radar, a blind zone will be formed close to the Radar.
The vertical detection angle of the Radar is ±α (Generally, if signal
strength is –3 dB, α is 10°). For detailed maximum blind zone
distance, see Figure 2-2.
How does the Radar
perform in severe weather?
Electromagnetic wave of the Radar can detect the target in
blurry visual conditions such as heavy fog.
In foggy or rainy days, radar's detection range might decrease
slightly for the reason that electromagnetic wave might be
damaged more or less. However, there is certain redundancy
for the Radar performance when it leaves the factory, so it can
conform to the standard requirements even though it is
influenced by adverse factors.
A false alarm might occur in areas with hail or heavy snow.
