Figure 2. The HD’s radar footprint
˿For best performance, make sure the lanes being detected are all
parallel to each other; avoid on- and o-ramps/turn lanes that angle
away from the road.

10 • SmartSensor HD User Guide
˿Make sure all monitored lanes are within 6 to 250 . (1.8 to 76.2 m)
of the sensor. Up to 22 lanes can be detected.
˿If you’re putting a sensor on a road with stoplights or stop signs,
position the sensor toward middle of the block, to reduce the likeli-
hood of having stopped vehicles in the HD radar footprint.
Figure 3. Midblock installation
˿Keep cable lengths in mind when you pick mounting locations;
when you use the Wavetronix cable, cables can be as long as 600 .
(182.9 m) if you’re using 24 VDC and RS-485 communications; for
longer connections, consider alternate wired and wireless options.
˿Consider timing: aer a vehicle passes in front of the sensor, there’s
a slight delay before the data for that vehicle is sent from the sensor.
In a time-sensitive application, like supplying a variable message
sign with per vehicle warning messages, make sure the sensor is far
enough upstream from the sign that the system has time to collect
the data, process it, and send it to the sign by the time the vehicles
reach the problem area.
˿See if you can take advantage of any existing infrastructure in the
area. e sensor can be mounted on existing poles (with the excep-
tion of wooden poles and trees), as long as they fall within the
acceptable oset range. You may also be able to tap into existing
cabinets, power sources, and communication networks. All of these
options could save you time and money.
For more information.

section of the
Wavetronix website
to learn more about
cable lengths.

bottom of the pole. If
installing a new pole,
remember that part
of the pole will likely
be below ground.
Definition. Offset is
the distance between
the pole the sensor
is mounted on and
the edge of the first
lane to be detected.

Additional information
˿If the roadway is frequently used by tall vehicles, consider choosing a
higher mounting height to help avoid occlusion.
˿Don’t use an oset of less than 6 . (1.8 m). Also, the sensor can be
up to 230 . (70.1 m) from the road, but don’t go out that far if you
can avoid it; it could lead to decreased accuracy.
˿For best results, choose the mounting height in the Height column
in the table. If you can’t, just keep it somewhere in the acceptable
range.
Note. Some countries,
such as the UK, have
their own variant
of these mounting
guidelines due to
differences in road
layouts and traffic
profiles. Please
consult with your
local Wavetronix
office to ensure
you are installing
to the correct local
guidelines.

Chapter 1: Choosing a Mounting Location • 13
Occlusion and multipathing
ese are two problems you might face while using a radar detector.
Figure 4. Occlusion
Occlusion occurs when one object blocks another object from the sen-
sor’s view, as shown above. is can happen with
˿Tall vehicles like semi trucks
˿Signs
˿Barriers and sounding walls
˿Trees and more
Normal
detection
Signal that doesn’t
return to sensor is
scattered
Signal bouncing off
wall causes false
detection
Figure 5. Left: direct path return; right: multipath return
Multipathing occurs when a large at surface near the sensor interferes
with detection. A radar signal can bounce around several times between
the surface and the vehicles before returning to the sensor. is can
make the sensor detect a vehicle where there is none.

14 • SmartSensor HD User Guide
is can happen with
˿Buildings
˿Signs
˿Guard rails
˿Sounding walls and more
Fixing occlusion problems
˿Move the sensor higher on the pole (keeping it within the recom-
mendations in the mounting guidelines table).
˿Move the sensor to another spot on the freeway if possible, away
from obstructions.
˿If there’s a very large barrier in the median, you could do the following:
Use one sensor on either side of the road, pointing in (be sure to
give the two sensors a 70-./21.3-m lateral oset and put them on
dierent RF channels).
Put two sensors on the same pole in the middle of the median,
both pointing out (put them on dierent RF channels), but this
would mean they are next to the barrier in the median and that
could cause multipath problems.
Fixing multipath problems
˿Move the sensor if possible; make sure it is separated from overhead
signs, overpasses, tunnels, parallel walls, etc. A 30-. (9.1-m) lat-
eral separation would be ideal, but even just a few feet can make a
dierence.
˿Adjust the sensor’s sensitivity thresholds in SmartSensor Manager
HD, as covered in chapter 8.
Note. A good rule of
thumb is that 50% of a
vehicle must be visible
above any barrier in
order to be detected.

Installing the
SmartSensor HD
Attaching the mount to the pole
Figure 6. Attaching the mount
1 Insert the mounting straps through the slots on the mount.
2 Position the mount on the pole at the height you chose from the
mounting table in the previous chapter.
3 Point the head of the mount toward the middle of the lanes you want
to detect.
4 Tighten the straps.
Note. Be sure to
keep the straps
adjustable, because
once you’ve used the
alignment tool in the
software, you may
need to fine-tune the
sensor’s positioning.

16 • SmartSensor HD User Guide
Attaching the sensor to the mount
Figure 7. Attaching the sensor
1 Align the bolts on the sensor’s backplate with the holes in the mount.
2 Make sure the large 10-pin connector at the bottom of the unit is
pointing towards the ground.
3 Push the bolts through the mount holes.
4 Place the lock washers on the bolts, thread on the nuts and tighten.
Aligning the sensor to the roadway
Figure 8. Up-and-down positioning
1 Tilt the sensor down so the front is aimed at the center of the detec-
tion area.

Chapter 2: Installing the SmartSensor HD • 17
Figure 9. Rotating the sensor on a hill: incorrect (left) and correct (right)
2 If the sensor is installed on a road with an uphill/downhill grade,
rotate the sensor so that the bottom edge matches the grade of the
road (this will require the purchase of a rotating sensor backplate).
Figure 10. Side-to-side positioning
3 Adjust the side-to-side angle so it’s perpendicular to the ow of trac.
Applying silicon dielectric compound
Figure 11. Applying the compound

18 • SmartSensor HD User Guide
1 Tear the tab o the tube of silicon dielectric compound that came
with the sensor.
2 Squeeze about half of the compound on the connector at the base of
the sensor.
Connecting the cable
Figure 12. Cable run through pole (left) and through conduit (right)
1 Insert the cable connector into the sensor connector. Be aware that it
is a keyed connector.
2 Twist the cable connector clockwise until you hear it click into place.
3 Run the cable through the pole. Leave a small amount of slack at the
top; this reduces strain, allows you to create a drip loop as shown
above, and gives you something to work with should you someday
need to move the sensor to a dierent spot on the pole.
4 If there’s excess cable, don’t cut it, as you may need it at a later time;
leave it in the pole.
Note. The HD sensor
uses an 8-conductor
cable that can
be ordered from
Wavetronix. It’s also
possible to order a
retrofit HD with a
legacy connector;
this would use the
older 9-conductor
SmartSensor cable.
Note. When you run
the cable through the
pole, don’t drill through
the sensor mount, as
the sensor and sensor
mount may need to be
adjusted in the future.

Installing Power, Surge
Protection and Communications
How you install power, surge protection and communication modules
varies based on what enclosures you’re using and where they’re located.
Installations with a pole-mount box only
As shown below, this is an installation where the sensor cable runs down
the pole to the pole-mount box and to nowhere else. Power comes from
solar, a battery, or a power line that runs straight to the pole; communi-
cations are wireless or use a comms line that runs straight to the pole.
Figure 13. Installation with pole-mount box and no cabinet
Warning. We strongly
recommend you follow
the guidelines in this
chapter, especially as
they relate to surge
protection. Failure to
properly protect your
sensors from surges
will void the sensor
warranty. If you need
