2 Overview of Wireless Video Image Detection Vantage Wireless System Installation Guide
Overview of Wireless Video Image Detection
Any major city that relies on vehicle detection for its signal control
system eventually experiences damage to traditional inductive
loops due to roadway construction or pavement failure. Damage
to inductive loops from road widening or re-surfacing projects can
compromise the reliability of vehicle detection. Maintaining
optimum traffic flow during construction can be difficult due to
temporary striping and lane closures.
Adverse weather conditions also impede repair of inductive loops
and at times may delay repair activities for several months. During
such times, intersections that rely on a failed inductive loop may
go into max-recall for the duration.
The use of wireless video transmission facilitates rapid
deployment for permanent and temporary applications while
maintaining superb vehicle detection where inductive loops or
other vehicle detection methods cannot be deployed or repaired.
Benefits of Standard and Wireless VIDS
Although wireless video communications technology is not new,
its application in vehicle detection provides enormous benefits.
Video image detection systems (VIDS) in general provide
flexibility in the placement of vehicle detection zones. Temporary
lane closures and lane markings can be easily accommodated by
moving the detection zones of the video image processor.
At intersections with a high volume of heavy vehicles, the constant
abuse of the roadway surface from heavy vehicles requires
inductiveloopstobereplacedeveryyear.Forthesetypesof
locations, VIDS is an excellent alternative detection method.
Utilizing wireless video transmission between the VIDS camera
and video image processor provides additional flexibility where
quick and low cost deployment is required. At many locations,
running high-quality coaxial cable may be difficult or impossible
because existing conduits are filled to capacity, blocked with
debris, or even frozen. Wireless video technology provides cable-
free live video from the VIDS camera to the controller cabinet,
where the video image processor is housed.
Document 4931005, Version 2.0 Overview of Wireless Video Image Detection 3
2.4 GHz FM Video Transmission
The ITERIS Wireless Vantage System utilizes the license-free 2.4
GHzbandtotransmitlivevideofromtheVIDScameratothe
controller cabinet. A wireless transmitter is integrated into the
camera and has no external components other than a 3-inch
“rubber ducky” antenna. The video transmitter is FCC compliant
and does not require the end user to have an operator license from
the FCC.
The wireless transmission system uses frequency modulation (FM)
techniques to transmit the video. This modulation scheme, unlike
spread spectrum transmission where data is digitized prior to
transmission, uses analog methods to modulate the video signal.
Digital transmission typically requires higher bandwidths than
FM-based systems.
There are several reasons why the 2.4 GHz band was selected.
Video transmissions in the 902-928 MHz unlicensed band require
too much bandwidth, and the 5.8 GHz unlicensed band encounters
signal reflections common to higher frequency devices at locations
where several obstructions and radio wave reflectors exists. Since
wireless video transmission devices are mounted at lower
elevations, signal poles, mast arms, signal heads, and even vehicles
may cause havoc with multipaths and reflections, resulting in
image ghosting, image shifting, and possibly even image
cancellation. The 2.4 GHz band avoids these problems.
Benefits of Using FM-Based Video Transmission
The question arises: How can multiple intersections use wireless
VIDS if they use the same frequency? This is possible because of
thenatureofFMcommunications.
Frequency modulation receivers detect and use the strongest
signal they receive. Wireless Vantage video transmitters are low-
power devices. Signal strengths of adjacent intersection video
transmitters are significantly lower than local transmitters and do
not cause interference, provided that adjacent intersections are at
least 250 feet away.
Other benefits of FM-based video transmission:
•Proven video transmission technology.
•Ease of deployment.
•Lower maintenance costs (does not require expensive
digital test equipment).
4 Overview of Wireless Video Image Detection Vantage Wireless System Installation Guide
Camera Power
The portability of the Wireless Vantage VIDS hinges upon how
power is provided to the camera. Since the recommended
mounting location of the Vantage wireless camera is on the safety
light arm above the signal head, the luminaire circuit supplies the
camera power. The only requirement is that the luminaire head be
controlled by its own photocell.
In this manner, power for the camera can be tapped prior to the
photocell by hardwiring in the power cable or by using a photocell
power adapter or power take-off (PTO) placed between the
photocellanditsreceptacle(seeFigure1).Thephotocellcanstill
provide nighttime switching capabilities while providing
continuous 24-hour power to the camera.

Receiver Antenna Type and Location
The wireless video receiver is located in the controller cabinet, and
its baseband video output provides full-motion video to the
Vantage VIDS. Getting clean, optimum radio waves to the video
receiver takes careful planning prior to system installation. As
with any wireless transmission, radio wave reflections, multipaths,
and obstructions can degrade signal quality.
For optimum radio wave signal reception, the receiver antenna
should be placed as high as possible to eliminate reflections from
ground level objects, such as pedestrian signal heads and moving
objects (high-profile vehicles, for example). The receiver antenna
height also dictates the amount of signal degradation induced
from pedestrians. A minimum height of 20 feet is recommended
for most applications. Some sites may require additional receiver
antenna height if direct line-of-sight between the transmitting
antennas and receiver antenna cannot be achieved.
A linear-polarized directional patch antenna for receivers provides
the best results in most applications. This type of antenna typically
has a 60–90 degree angle of reception and is designed for vertical
or horizontal polarization. A linear-polarized antenna rejects
reflected radio waves since polarization of reflected signals is
typically shifted in some manner. In addition, a patch-type
directional antenna provides rejection of reflected radio waves by
rejecting signals coming from behind the patch antenna.
Other Applications
Other applications for wireless VIDS are construction management
activities during road widening, intersection improvements, or
temporary lane closures. Locations where road surfaces are
continually damaged by heavy vehicles or severe weather can also
benefit from the use of wireless VIDS. At these locations,
permanent installations of the wireless system significantly
reduces recurring maintenance costs and headaches.
Mid-block vehicle detection can benefit from the use of wireless
VIDS by eliminating the need to install conduit and cabling from
the mid-block detection location to the intersection controller
cabinet. A higher-gain Yagi receiver antenna can be used to extend
reception distance to more than a mile.
The use of wireless technology in VIDS applications expands the
flexibility for deployment. Coaxial cable and other hard wiring are
no longer limiting factors. ITERIS has integrated their proven
Vantage VIDS with wireless video transmission to provide a more
flexibleVIDSproductthataccommodatesalmostanyintersection
and mid-block configuration.

Installing the Camera and Receiver Unit
Basic Installation Steps
Installing the Vantage wireless camera and receiver unit requires
the following steps:
1 Mounting the wireless camera/transmitter unit.
2 Connecting power to the wireless camera/transmitter unit.
3 Mounting the receiving antenna.
4 Connecting the receiving antenna pre-amp.
5 Installing the antenna coax cable.
6 Installing the antenna coax cable connectors.
7 Installing the bias-T and surge protection device.
8 Wireless receiver unit connections.
9 Determining wireless camera frequency.
10 Setting wireless receiver frequency.
11 Adjusting the antenna to obtain maximum RF signal
strength.
12 Adjusting the wireless camera focus and field of view.
Mounting the Wireless Camera/Transmitter Unit
To mount the wireless camera/transmitter unit, follow the
instructions for mounting a standard camera as described in your
Vantage Installation and User Guide. The connections required for
the wireless camera/transmitter unit are described in the next
section of this guide.
Document 4931005, Version 2.0 Installing the Camera and Receiver Unit 11
Connecting Power to the Wireless Camera/Transmitter
Unit
The RZ-3 wireless camera/transmitter unit can be powered using
either 120 or 220 VAC. The photocell power adapter (or power
take-off unit) can be used to provide 120 VAC to the
camera/transmitter unit (see Figure 5.
The new photocell power adapter can be used for either 120 or 220
VAC applications as a convenient power source for the
camera/transmitter unit. To use the photocell power adapter:
1 Remove the existing photocell.
2 Plug in the photocell power adapter in its place.
3 Install the original photocell into the top of the adapter.
4 Rotate the photocell as needed to orient it in the correct
direction (pointing north).
In some cases, luminaires have shorting plugs installed in the
photocell sockets. In this situation, the actual switching is probably
occurring at the service or cabinet utilizing a single photocell and
contactor relay. You can sometimes install a shorting cap at this
point, remove the shorting caps on the luminaires, and install the
Vantage photocell adapters along with individual photocells to
avoid having to use another power source.
If you cannot use the photocell power adapter, you need to
provide the camera with another source of 120 or 220 VAC. Use a
three-conductor, Neoprene, type SJOW, 16-AWG power cord.
Figure 5. Photocell Power Adapter / Power Take-Off Unit (PTO)
The photocell power adapter comes with an attached Deutsch
connector that plugs into the back of the camera/transmitter unit
to provide power (see Figures 6 and 7).
The 10 AWG green wire needs to be attached to the camera
mounting bracket and grounded to the signal pole arm (see
Figure 8). When attaching the ground wire:
12 Installing the Camera and Receiver Unit Vantage Wireless System Installation Guide
•Secure the ground bolt assembly to the camera bracket.
•Tighten the bottom of the bolt so that it digs into the pole
and provides good electrical contact with the pole arm.

Although it depends on your installation configuration, coax cable
must be pulled from the receiving antenna to the traffic control
cabinet.UsetypeLMR-400coaxcabletoconnectfromthe
receiving antenna to the cabinet. Coax cable specifications are on
page 35. The coax cable run should not exceed 150 feet.
Coax cable connections inside the cabinet are described in Making

If you are not using the photocell power adapter, the power cable
for the camera should be an SJOW-type, three-conductor, 16-gauge
cable.
INSTALLING COAX CONNECTORS
Coax cable specifications are listed on page 35.
To install a coax connector, follow these steps:
1 Use a sharp utility knife to strip the end of the coax cable as
showninFigure15.Becarefulnottoscoreornickthe
shield, dialectric, or center conductor.
2 Insert the end of the coax cable into the connector body as
shown in Figure 16. Thread the connector body onto the
outer sheath of the cable.
Note If there is foil on the dielectric, make sure the foil does not
make contact with the center conductor.

a Set your multimeter to the continuity or resistance
setting (ohms).
b Place one meter test lead so it touches the connector
center pin. Place the other test lead so it makes
contact with the connector body. With both ends of
the coaxial cable disconnected from any equipment,
you should have infinite resistance between these
points (no continuity).
If you do have a low resistance (continuity), there is
a short somewhere in the coax cable or connector. It
is most often at the connector due to improper
assembly. Examine the coax for cuts or tears. If
there is no visible damage, remove and re-install the
connector.
Measure the connector again after it is removed
from the cable. If the short disappears, the problem
is in the connector. If there is still a short, the
problem is with the cable.
Fix any problems before proceeding.

process for the holes on both sides of the connector.
Establish a good electrical connection between the
coax braided shield and connector body, and
between the center pin and coax center conductor.
The solder connections should be bright and shiny,
not dull and pitted (which results from cold solder).

20 Installing the Camera and Receiver Unit Vantage Wireless System Installation Guide
Figure 18. Soldering the Coax Cable and Connector Body
5 After soldering the center conductor in place, check the
connector again for shorts as described in step 3.
6 Perform an additional test for continuity. To perform this
test, take a jumper clip lead and short the center pin on one
of the connectors to the connector body. Go to the other
non-jumpered connector and measure from the center pin
to the connector body. You should measure a low
resistance (continuity).
If the resistance is over 10 ohms (no continuity), there is a
problem. It could be a broken center conductor in the coax
cable or (most likely) a poor or improper connection at the
coaxial connectors. Isolate the problem as described in
step 3b.
Note Poor connections on the receiver coax cable can result in poor
signal strength. Make sure these critical connections are done
correctly. If you are not familiar with proper soldering
techniques, consult another reference on the topic.
7 After verifying that there are no shorts, screw the connector
body and connector shell together as shown in Figure 19.
Use two adjustable wrenches (one to hold the connector,
the other to tighten it).

INSTALLING THE BIAS-T AND SURGE PROTECTION
DEVICE
1 Attach the bias-T to the LMR-400 coax cable that you pulled
into the cabinet from the antenna and pre-amp. Orient the
bias-T so that the RF-DC side goes to the antenna and the
RF side goes to the surge protector and receiver unit. See
Figure 20.
CAUTION The bias-T must be oriented correctly and located
between the pre-amp and surge protection device.
Improper installation will result in poor operation
and may also blow the receiver power supply fuse
and damage the pre-amp, bias-T, and receiver unit.
Figure 20. Bias-T
2 Plug the power cord from the bias-T into the 15 VDC
receptacle on the receiver unit.
In addition to providing power to the bias-T, power is
supplied to the pre-amp from the bias-T through the coax
cable without interference to the video signal and without
requiring additional wiring.
3 Install the male-to-male barrel adapter to the RF side of the
bias-T, and connect the SURGE side of the surge protection
device to the other end of the barrel adapter.
4 Assemble the surge protection device as shown in Figures
21 and 22. (Use a PolyPhaser IS-MT50LN, PSX, or suitable
equivalent. See page 36 for specifications.)
•Be sure to install the orange “O” ring into the
groove on the suppressor body.
•Properly ground the bracket using 10 AWG green

RECEIVER UNIT CONNECTIONS
Receiver units require several connections:
•The receiver unit requires a power source. Single-channel
receivers have a plug-in wall transformer power supply
that runs off 120 VAC. Multi-channel receivers have a
detachable power cord that needs to be plugged into a 120
VAC outlet.
•As described previously, the bias-T power cord must be
plugged into the 15 VDC receptacle on the receiver unit in
order for the pre-amp to operate properly.
•TheSMAsideoftheN-to-SMAadaptercablemustbe
connected to the SMA antenna input on the receiver.
•A short BNC-to-BNC jumper cable of Belden 8281F must be
attached from the video output to the Vantage unit video
input. Single-channel receivers require an RCA-to-BNC
adapter to adapt the RCA-type video output to a BNC-type
output connector.
•The receiver chassis must be grounded by attaching a green
10 AWG wire to the chassis grounding lug and running the
wire back to the cabinet grounding buss.
Figure 25 shows some of connectors and adapters that may be
needed when making these connections.

INSTALLING A SIGNAL SPLITTER
If you have multiple cameras and single-channel receivers, you
also need to install a signal splitter. Specifications for the signal
splitter are on page 38.
Note A separate signal splitter is not necessary with a multi-
channel receiver, which has a signal splitter inside the unit.
In this configuration, connect a jumper cable between the surge
protector and the input on the signal splitter, and then connect a
jumper cable between an output on the signal splitter and each
receiver unit. See Figure 26.

Setting the Receiver Frequency
SETTING THE FREQUENCY FOR SINGLE-CHANNEL
RECEIVERS
The frequency on the single-channel receiver is set using DIP
switches. The location of the DIP switches is shown in Figure 28.
Figure 28. Single-Channel Receiver DIP Switches
To set the frequency for a receiver, carefully remove the circular
access cover on the receiver unit to access the DIP switches, then
set the DIP switches to the appropriate frequency as listed in
Table 2 and shown in Figure 29.
Figure 29. Receiver Frequency DIP Switch Settings
CAUTION Turn on the DIP switch for one frequency only, and
leave all other DIP switches off. If you turn on the
DIP switch for more than one frequency, you may
damage the receiver.

Figure 32. Tuning the Receiving Antenna
Measure the receiver signal strength using the DC measurement
scale on a standard multimeter. Using banana-type jack adapters,
insert the meter probes into the color-coded test points on the
receiver unit to measure the DC signal strength. (For single-
channel receivers, see Figure 2 on page 6 and Figure 33. For multi-
channel receivers, see Figure 4 on page 7 and Figure 34.)
The signal strength should be 1–4 VDC. For optimal performance,
the signal strength should exceed 1.5 VDC.
Rotate the receiving antenna until you obtain the maximum
average signal strength. When you find the best position, tighten
the antenna permanently into place. Make sure the coaxial cable
has a drip loop, and tie-wrap it for added strain relief.
If you have multiple single-channel receivers or a multi-channel
receiver, you need to obtain the highest average signal strength for
each receiver or channel. Realize that adjusting the antenna to
obtain a higher reading for one may degrade the signal strength of
another. Adjust the receiving antenna to find a happy medium.

Adjusting the Camera Focus and Field of View
The field of view and focusing adjustment is the same for the
wireless camera as for the normal Vantage video camera. Refer to
your Vantage product user and installation guide for a description
of how to adjust the camera focus and field of view.
To adjust the camera focus and field of view, you need to connect a
Lens Adjustment Module (LAM) to the BNC connector on the back
ofthecameraasshowninFigure35.

Troubleshooting
If you have no video, poor video, or low signal strength, check the
following table
Table 3. Troubleshooting
Potential Problem See Page
Are all camera/transmitter units within the 120 degree operating
window of the receiving antenna?
29
Is the antenna adjusted to provide a signal strength of 1.5 VDC or
greater to all camera/transmitter units?
29
Are their any obstructions blocking the receiving antennas “line of
sight” path to any of the camera/transmitter units?
29
Are the pre-amp, bias-T, and surge protector connected in the correct
order and orientation?
•Make sure that the bias-T is in front of the surge protector (between
the surge protector and the antenna pre-amp).
•Make sure that the RF DC side of the bias-T is connected to the
pre-amp and that the RF side of the bias-T is connected to the surge
protector.
•Make sure the IN side of the pre-amp goes to the antenna and the
OUTsideofthepre-ampgoestotheRFDCsideofthebias-T.
21
Make sure that the pre-amp is mounted with the receiving antenna. 15
Make sure that the pre-amp connections are correctly weatherproofed. 16
Make sure that the bias-T’s power cord is plugged into the receiver unit. 21
Check the 15 VDC fuse in the fuse holder above the bias-T power plug
to make sure it is still good. Fuse is 250V 500mA.
6, 7
Check the coax cable from the cabinet to the receiving antenna:
•Makesurethecablerunislessthan150feet.
•Make sure that LMR-400 cable is used.
•Make sure that the connectors are installed correctly.
