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 inductive loops to be replaced every year. For these types of 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 cablefree live video from the VIDS camera to the controller cabinet, where the video image processor is housed. Overview of Wireless Video Image Detection Vantage Wireless System Installation Guide 2.4 GHz FM Video Transmission The ITERIS Wireless Vantage System utilizes the license-free 2.4 GHz band to transmit live video from the VIDS camera to the 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 the nature of FM communications. Frequency modulation receivers detect and use the strongest signal they receive. Wireless Vantage video transmitters are lowpower 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). Document 4931005, Version 2.0 Overview of Wireless Video Image Detection 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 photocell and its receptacle (see Figure 1). The photocell can still provide nighttime switching capabilities while providing continuous 24-hour power to the camera. Transmitter antenna Vantage wireless camera/ transmitter unit Photocell Power adapter Luminaire (safety light) arm Luminaire Figure 1. Vantage Camera Power Overview of Wireless Video Image Detection Vantage Wireless System Installation Guide 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 flexible VIDS product that accommodates almost any intersection and mid-block configuration.

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. 10 Installing the Camera and Receiver Unit Vantage Wireless System Installation Guide 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: Remove the existing photocell. Plug in the photocell power adapter in its place. Install the original photocell into the top of the adapter. 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: Document 4931005, Version 2.0 Installing the Camera and Receiver Unit 11 • 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.

In Out Antenna side Cabinet side Figure 10. Antenna Pre-Amp The pre-amp should be connected as shown in Figure 11. When connecting the pre-amp: • Do not mount the pre-amp in the cabinet. • The pre-amp should be mounted as close to the antenna as possible. • Make sure the bias-T and pre-amp are correctly oriented. • For optimal performance, the total LMR-400 coax cable run from the antenna to the receiver should not exceed 150 feet. To connect the pre-amp: Connect the end of the antenna coax cable to the IN side of the pre-amp. See Figure 12.

LMR 400 coax cable Securing the Pre-Amp Installing the Receiver Coax Cable CABLE TYPES Although it depends on your installation configuration, coax cable must be pulled from the receiving antenna to the traffic control cabinet. Use type LMR-400 coax cable to connect from the 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 Connections Inside the Cabinet on page 21. 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: Use a sharp utility knife to strip the end of the coax cable as shown in Figure 15. Be careful not to score or nick the shield, dialectric, or center conductor. 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 Document 4931005, Version 2.0 If there is foil on the dielectric, make sure the foil does not make contact with the center conductor. Installing the Camera and Receiver Unit 17 Center conductor Teflon foam dialectric 7/16" Braided shield Coax cable outer sheath 1/4" /16" Figure 15. Stripping the Coax Cable Connector body Figure 16. Coax cable Attaching the Coax Connector Body Check the connector for shorts as shown in Figure 17. Set your multimeter to the continuity or resistance setting (ohms). 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. 18 Installing the Camera and Receiver Unit Vantage Wireless System Installation Guide Figure 17. Checking the Coax Connector for a Short Solder the cable to the connector body at the points indicated in Figure 18. Make sure the soldering gun tip is clean and well tinned. Make sure you can visibly see the braided shield and the copper center conductor through the holes in the connector body. Heat the connector body with the soldering gun until solder flows into the holes for the center conductor and the braided shield. Repeat this 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). A low power soldering iron will not have the wattage to adequately heat up the connector to allow the solder to flow properly. Make sure you are using a high heat soldering gun with a rating of at least 100/140 watts. CAUTION Do not overheat the connector. Overheating can cause the dielectric to melt and allow it to create a short between the center conductor and the shield. Document 4931005, Version 2.0 Installing the Camera and Receiver Unit 19 Solder holes Figure 18. Soldering the Coax Cable and Connector Body After soldering the center conductor in place, check the connector again for shorts as described in step 3. 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. 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). Connector shell Figure 19. 20 Installing the Camera and Receiver Unit Coax cable Assembling the Connector Body and Shell Vantage Wireless System Installation Guide Making Connections Inside the Cabinet INSTALLING THE BIAS-T AND SURGE PROTECTION DEVICE 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. 15 VDC in Bias-T power plug RF DC (pre-amp/antenna side) RF (surge protection side) Figure 20. Bias-T 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. 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. 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.) Document 4931005, Version 2.0 • Be sure to install the orange “O” ring into the groove on the suppressor body. • Properly ground the bracket using 10 AWG green wire. Installing the Camera and Receiver Unit 21 Figure 21. Figure 22. Surge Protection Device (Exploded View) Surge Protection Device (Assembled) Use the N-to-SMA adapter cable (see Figure 23) to connect the surge protection device to the receiver unit. The N connector side of the cable connects to the PROTECTED side of the surge protector, and the SMA side of the cable connects to the ANTENNA input connector on the receiver. Figure 24 shows the bias-T, surge protection device, and receiver properly connected.

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. • The SMA side of the N-to-SMA adapter cable must be 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.

Specifications for the signal splitter are on page 38. Note A separate signal splitter is not necessary with a multichannel 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.

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 singlechannel receivers, see Figure 2 on page 6 and Figure 33. For multichannel 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. 30 Installing the Camera and Receiver Unit Vantage Wireless System Installation Guide Multimeter DC voltage test points Receiver Figure 33.

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 of the camera as shown in Figure 35. Lens adjustment module (LAM) Figure 35. 32 Connecting a LAM to the Camera Installing the Camera and Receiver Unit Vantage Wireless System Installation Guide 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? 21 • 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 OUT side of the pre-amp goes to the RF DC side of the bias-T. 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: 15 • Make sure the cable run is less than 150 feet. • Make sure that LMR-400 cable is used. • Make sure that the connectors are installed correctly. Make sure the camera/transmitter rubber duck antenna is in a vertical (NOT horizontal) position.
