1. Receiving Inspection
• When you receive your SpeedSpy™, you will want to inspect all
the components for freight damage. Take pictures to document
any damage.
• Notify the freight company immediately of any damage,
preferably while the driver is present.
• Record the damage on the bill of lading and keep a record of the
problems or damage.
• Inspect the SpeedSpy™ for scratches or nicks that might have
happened during shipping.
2. Setup
2.1 Find a Good Location
Position the SpeedSpy™ in a straight line of sight from the motorist’s
view, either before or after a curve and not at a sharp corner (See
Figure 4.2 Angular Interference). The SpeedSpy™ can be mounted on
most roadside poles with the included hardware.
WARNING:
Before proceeding, open the enclosure and remove
any items that are not bolted in place. Remove the 12
VDC battery by unscrewing the three wing nuts from
the battery retaining plate. Disconnect the white
Molex connector. Remove the battery retaining plate
and carefully lift the battery unit with wire harness
completely out of the enclosure. For more on this see
Section 3.1 - Removing the Battery.

2.2 Setting Up the SpeedSpy™
Before rst use, plug the charger into a 110 – 120 VAC wall socket
and charge the rst battery by connecting the male/female (white)
Molex™ 2-pos connectors. Refer to the charger manual for further
instructions. After charging the rst battery, disconnect the Molex™
connector and attach the second battery and charge it.
1. The SpeedSpy™
includes an integral
mounting plate
assembly for attaching
to roadside poles.
Use the universal
clamp kit to mount
the SpeedSpy™
bracket to the pole
rst with the security
lock hole facing up.
(Figure 2.2b) Please
refer to the universal
clamp kit package for
instructions for sizing the stainless steel straps.
2. Clamp the mounting bracket to a pole. After cutting the straps
to correct length, run each strap through the side strap holes
located on the pole ange of the bracket. Make sure that the
security lock hole is facing up then place the mounting assembly
against the pole (4 -5 ft. from the ground facing trac ow),
position the straps, insert the fasteners and tighten. See Figure
2.2b.
3. Position the SpeedSpy™ enclosure onto the pole mounting
bracket by aligning the four base bolts into the four
corresponding bracket slots. Allow the enclosure to fall into
place. Secure the SpeedSpy™ enclosure by placing the supplied
lock through the security hole on the bracket. See Figure 2.2c

4. Unlatch the enclosure door and open. Insert one of the two
12 VDC lead sealed batteries. (See Section 3.1- Removing and
Attaching the Battery for details.)
5. Insert the EZ Stat™ module into the male 9-pin connector.
Reference the red locator label on the enclosure door.
6. Turn on the unit. The power switch is located inside the box.
The unit will operate for approximately two days before the
battery must be recharged. Close and lock the case. The unit is
waterproof only when the case is sealed. Failure to seal the case
may lead to permanent damage to the radar unit.
7. The EZ Stat™ will collect speed data events. The EZ Stat™ reads
vehicle speeds 5 times per second. When a moving object is
detected by the radar, the logger expects it to be present for
at least 4 seconds, then receive a zero speed. The maximum
speed will be recorded with the timestamp in the memory of the
logger module.
NOTE: The EZ Stat™ will not create a record if another car is in range
of the radar before the rst one passes beyond the antenna. When
trac is heavy, there will be no gap (zero speed) in speed readings,
and the EZ Stat™ will see the whole cluster of cars as one event.

3. Components
3.1 Removing the Battery
Start by removing the three battery plate wing nuts and the battery
retaining plate. The battery is positioned sideways with the battery
terminals on the right. Stand the enclosure on a at surface with the
battery upright. Next carefully pull the battery from the enclosure.
3.2 Installing and Attaching The Battery
Ensure that the three battery
plate wing nuts and battery
retaining plate have been
removed. Stand the enclosure
on a at surface with the
battery cavity upright.
Position the battery sideways
with the battery terminals on
the right and slide/push the
battery back between the guide tubes. Replace the battery retaining
plate and secure using the three wing nuts. Tighten the wing nuts
enough to secure the battery and prevent movement. Connect the
male/female white colored Molex™ connectors.
3.3 Battery Charger
The charger is designed
for mounting. However we
recommend that you use it
as a desktop device. Charge
the batteries at the oce to
minimize having to remove
the SpeedSpy™ enclosure. If

3.5 System Interface (SI-3)™
The SpeedSpy™ features the
Decatur Electronics System
Interface (SI-3)™ directional
radar—a high-performance
radar system that comes
congured to monitor only
the trac that is approaching
the radar antenna. Radar
sensitivity has been pre-set for
optimal operations. Fog, heavy
rain, snow, and blowing dust
can reduce the speed detection range.
3.6 EZ Stat™ Module
The SpeedSpy™ includes
an EZ Stat™ module and
the software application for
trac data collection.
3.7 Tuning Fork Test
If the SpeedSpy™ has come equiped with a tuning fork then the fork
can be used to verify that the logger is receiving speed data.
To begin the test, make sure the SpeedSpy™ is turned on and that
the EZ Stat™ data logger is plugged in. The green LED on the EZ Stat
will be blinking. There is 60 seconds from the time the SpeedSpy™ is
turned on in which to perform the test. After 60 seconds the system
would need to be turned o and back on if the test is to be repeated.
1. Tap the tines of the fork on a rm, non-metallic surface. The
tuning fork will ring audibly. Then place the tuning fork that you
Figure 3.5
SI-3™ Antenna

SpeedSpy™User’s & Installation Manual
12
tapped with the narrow side facing about 3 inches directly in
front of the antenna. (See Figure 3.7).
Figure 3.7
Place the vibrating tuning fork about 3 inches in front of the antenna
• Only tap the tuning fork against hard plastic, wood, and
materials that are softer than metal. Repeatedly tapping
the tines on hard surfaces, such as metal and concrete,
can damage the tines and invalidate the fork for future
tests.
2. Observing the LED on the EZ Stat™, pull the tuning fork to one
side so that the fork is no long able to be read by the antenna.
The LED on the EZ Stat™ will blink red once indicating that the
information has been saved.
If the LED does not blink red once, then there may be an issue with
the EZ Stat™. Remove the EZ Stat™ and plug it into the computer
that has the EZ Stat™ software installed on it. Open the software and
press the "Connect" button. Check to make sure that the box labeled
"Product" says "OnSite Series Trailers". If the box says "Decatur Radar"
then change the setting to "OnSite Series Trailers" and press the
"Disconnect" button and try the EZ Stat™ again in the SpeedSpy™.

4. How Radar Works
Understanding potential radar interference and what you can do
when it occurs can greatly increase the radar’s performance.
Determining a vehicle’s speed begins with the radar antenna
transmitting and directing a beam of microwave energy (radio
waves) at an approaching (or departing) target vehicle. When energy
from this beam strikes a vehicle, a small amount of the beam is
reected back to the antenna in the radar device. The reected signal
frequency shifts by an amount proportional to the speed of the
target vehicle. This is known as the Doppler eect. The radar device
then determines the target vehicle speed from the dierence in
frequency between the reected and transmitted signal.
4.1 Interference Sources and Remedies
When properly installed and operated, Doppler radar is extremely
accurate and reliable. However, variations in the environment can
cause situations and circumstances, which can cause spurious (erratic
and unusually low or high) speeds to be recorded.
4.2 Angular Interference (Cosine Eect)
The cosine eect causes the system to record a speed that is lower
than the actual vehicle speed. This condition exists when the target
vehicle’s path is not parallel to the antenna, including conditions
such as the vehicle traveling on a curve or a hill as shown in Figure
4.2.
Figure 4.2
The Cosine Eect
Velocity
Vector
Angle
SpeedSpy™

SpeedSpy™User’s & Installation Manual

As the angle between the beam of the antenna and the target
vehicle increases, the recorded speed decreases. Ideally, an angle
of zero degrees (0°) is preferable, because the recorded speed is the
actual target vehicle speed (see Table 4.2).
The following table shows the eect that an increasing angle has on
a recorded speed:
Horizontal Angle Degrees

80 mph 80 79 79 79 78 77 75 69 57 40 0
Table 4.2
Actual and recorded speeds at antenna-to-target angles
Small angles (less than 10°) have little eect on accuracy. As the angle
increases, the recorded speed decreases. At 90°, the target speed is
0 - grossly incorrect.
4.3 Feedback Interference
When the radar beam is directed at computer screens, streetlights
and other electronic devices, it can record spurious speeds. To correct
this type of interference, relocate the SpeedSpy™.

7. EZ Stat™ Data Logger
The SpeedSpy™ package includes a USB Product ash drive, a USB
cable and the EZ Stat™ module.
• When the EZ Stat™ is used with one of Decatur
Electronics's trailer products, such as the SpeedSpy™,
the EZ Stat™ draws power from the SpeedSpy's™ serial
connector. Non-Decatur products that have serial
connectors will not have this special power connection
and therefore will not be able to power the EZ Stat™.
Figure 7
Flash Drive, USB cable and EZ Stat™Module.
7.1 EZ Stat™ Module
Use the EZ Stat™ module to collect trac data from a select number
of Decatur’s speed measurement products.
• Data is only collected in real time. The OnSite™ product
does not store data in a le for later transfer. Instead
speed data is sent immediately to the EZ Stat™. For that
reason the EZ Stat™ must be left connected until such
time as data analysis is needed.
7.1.1 The USB Port
The EZ Stat™ has a mini-USB receptacle. Use the included USB cable
to connect the EZ Stat™ to the computer's USB port.
7.2 EZ Stat™ Software Installation
The ash drive contains the User Manual, EZ Stat™ software along
with additional information on Decatur products. (Refer to Section

SpeedSpy™User’s & Installation Manual
19
9.2 for installation instructions.) Use the EZ Stat™ software application
to examine data collected with the module.
• To install the Decatur EZ Stat™ software you must
have administrative rights. In addition, the software
automatically downloads a driver from the web.
Therefore, the computer must be connected to the
internet and the automatic update feature must be
enabled, otherwise an error message will occur when
you try to run the application.
