Hawkeye Radar Installation and Maintenance Guide for Freeways v2.0 PAGE 1
Hawkeye is an advanced front-firing radar unit with unprecedented detection and
data collection capabilities. The radar can detect vehicles up to 1000 feet away from
it. It provides separation in speed, range and angle with nearly 100% accuracy, and
utilizes high-speed modulation of adaptive beams to achieve those results.
To take full advantage of the technology, the traffic professionals and any deployment
project parties must ensure that the solution components and adjacent parts
are properly assembled and installed. Rhythm has been partnering with top
manufacturers with proven track record of development and innovation in the field of
traffic and overall detection technologies.
The Hawkeye hardware solution components and physical parts have been approved
for quality by Agency Standards: UL497B and UL508A. They are compliant and
compatible with NEMA TS1, TS2, and ATC traffic cabinets and controllers via industry
standard connections. The Hawkeye radar solution has been devised to integrate
well with both Rhythm-owned deployments and with new, brand-agnostic solutions.
Tip: For information on utilizing the Hawkeye data analytics soware, refer to the
Hawkeye ASPM/AFPM User Guide.

CHAPTER 2 - Tools
and Equipment
Tools and Equipment Needed
• ”(13mm) socket and socket wrench or combination wrench
• Slotted screwdriver
• Band straps and fastening tool
• Network cable tester
• Shielded Cat6 RJ45 connectors and crimping tool
• 12 AWG copper wire; wire strippers
Network Cable Terminations
1. All network cable terminations should be pinned according to EIA/
TIA T568B specifications.
Fig. 1 Wiring with RJ45 Pinouts per T-568B Standard
Note: If cabling is connected to the camera and/or radar before being
properly terminated and tested, warranty is null and void.
2. Test the network cable terminations using a Fluke Micro Scanner or a similar device,
before plugging in the equipment. Required data shown on the tester is Length,
Resistance, Frequency, and Insertion Loss Margin.

Networking Bandwidth
To operate successfully following the installation, the Hawkeye radar solution requires
network connection within steady networking bandwidth. This chapter provides an
overview of the available communication methods.
“Bandwidth” is the amount of network communication traffic that can flow through a
given point. Think of bandwidth as plumbing and water as traffic. A small copper pipe
allows a small stream of water to flow, but to get more water to the other end faster,
you need a larger diameter pipe. Similarly, if you need more network traffic to get to
the other end faster, you need more bandwidth. Water traffic can be measured in cups
or gallons; network traffic is measured in “bits” and “bytes.” A byte equals eight bits.
* All bandwidth speeds are raw throughput speeds and do not count networking overhead, which can use up
to 30+% of the bandwidth.
** DSL and cable modem connections typically advertise their speeds as something like 1.5 to 10 Mbps.
However, this is the download speed. Hawkeye radar communication is more dependent on upload speeds.

Fiber Optic 10 Gbps (10,240 Mbps) @ 30

Wireless 54 Mbps Throughput varies depending on
distance and amount of vegetation/
buildings between antennae; typical
speeds range from 5 to 20 Mbps;
throughput also is dependent on the
WiFi standard being used; currently
standard 802.11n offers up to 300
Mbps
DSL/Cable Modem ** 128 Kbps - 1.5 Mbps DSL lines are not available everywhere;
throughput is strongly dependent on
the distance between the DSL modem
and the telephone central office switch
CHAPTER 3 – Networking Needs
for Infrastructure

Hawkeye Radar Installation and Maintenance Guide for Freeways v2.0

Tip: Be careful when reading specifications that mix bits per second (bps) with Bps
(bytes per second). For example, a 100 Mbps connection is slower than a 50 MBps
connection (50 MBps = 400 Mbps). There is also confusion regarding the definition of
“kilo.” In some computing contexts, it means 1024; in others it means 1000. Similarly,
“mega” can mean either 1,000,000 or 1,048,576 (1024 x 1024). However, these
numbers are close enough in practical terms to not matter.
Note: Rhythm Engineering requires a minimum of 2 Mbps download and
1 Mbps upload speed. It is recommended that customers consult their
Communications department and Rhythm Engineering for finding an optimal
networking solution for their specific deployment.
Networking Requirements
The Rhythm system uses Internet Protocol (IP) address labels to communicate. IP
communication is a robust and proven technology that has allowed the Internet
to evolve.
The word “Internet” in Internet protocol can be a little misleading – it is not
necessary for the network to be open to the public internet. Typically, the network
used by Rhythm products is either sequestered behind firewalls or totally isolated.
Municipalities with an existing networking plan can oen just incorporate the traffic
network into their broader networking scheme. However, it is required that Rhythm
Engineering can connect to the existing network by means of a VPN tunnel, to
provide remote support and maintenance to Hawkeye system units.
Before installing Hawkeye, be sure to have the following
networking items in place:
• A fully configured and installed router with VPN and firewall capabilities
• Ports 5000 and 5001 to be opened so that the processor can broadcast the
Hawkeye UI
• VPN access for at least four unique Rhythm users
• Static IP address assignments for each device processing unit, with designated
subnet/gateway
• Minimum bandwidth of 2 megabits per second (Mbps) download speed and
1 Mbps upload speed
Note: The only networking equipment provided by Rhythm Engineering is the
network switch that resides on the equipment panel (for communications at the
intersection). All other networking equipment must be purchased separately.
CHAPTER 3 – Networking Needs Post-Installation

Determine Where to Mount the Radar Sensor
The radar sensor will need to be mounted to a rigid pole, overhead sign, or extension arm.
If mounting on an overhead sign, do not mount the radar directly behind the sign, as this
will result in reflection interference.
Ideal mounting height for the radar should be between 25-30 . to the ground reference
point of the vehicles.
Fig.2 Location of radar mounting Fig.3 Direction of radar beam when
mounted properly
Install Extension Arms
When installing from a vertical pole, extension arms can be used to provide a more direct
view of the on-coming traffic for the radar sensor. Any extension arm must be at least 2“
nominal diameter.
Pull Network Cable
Outdoor, shielded, 23 AWG solid copper, direct burial rated Cat6 or better cable needs to
be run to the location where the radar sensor will be installed. Each Cat6 cable run must
be under 328 feet (100 m). If the run exceeds this length, Ethernet repeaters (approved by
Rhythm Engineering or procured from Rhythm Engineering) must be used.

CHAPTER 5 – Mounting the
Radar Assembly
The mounting bracket consists of four major components. Some assembly will occur
during mounting. The part underpinning the assembly is the radar bracket, which
needs to be adjoined to three additional parts.
The unit, when bolted together, allows mounting of the radar directly on a mast
arm or vertical pole. Band straps are used to attach the assembly to the pole. This
assembly supports alignment adjustments in three directions.
A context camera and an Ethernet surge protector will need to be mounted
separately and each of them fastened to the same pole. For instructions on installing
the context camera, check the Axis M2026 - Large FV Camera Installation Guide.
