SUBJECT: SMART STREET LIGHTS AND GUNSHOT DETECTION AS
COLLABORATIVE TECHNOLOGIES
The purpose of this informal report is to provide an update on the implementation of gunshot
detection technology in conjunction with smart street lights.
In cooperation with the Transportation and Public Works Department (TPW), Police have the
ability to mount gunshot detection equipment onto streetlight poles from which that equipment
can draw the continuous power that it needs to operate 24 hours per day and seven days per
week. However, this arrangement is problematic because it tends to be energy -inefficient and
reduces the lifespan of light fixtures. Newer technology, known as "smart streetlights," would
resolve this issue by providing integrated power taps for gunshot detection equipment, security
cameras, and other devices that require Internet connections. The Police Department is in the
process of implementing two different brands of gunshot detection equipment: Flock and Acoem.
Acoem equipment is compatible with smart streetlight technology, whereas Flock units are solar -
powered and do not require an external power source. Furthermore, the vast majority of security
cameras in use by the Police Department are compatible with smart streetlight technology.
Currently, the city has 69,000 streetlights and the plan is to install a smart node on each light or
circuit throughout the city. This will be a citywide implementation.
To generate investigative leads, gunshot detection should be paired with a security camera
and/or license plate recognition technology. Notification of gunshots alone, even in specific
locations, is not necessarily beneficial to investigators. Smart streetlight technology can
incorporate the use of pan/tilt/zoom cameras (PTZ), license plate recognition devices, and many
other forms of equipment. If the City was to use a fiber optic infrastructure as part of its smart
streetlights, there could be some operating cost savings associated with the use of security
cameras, license plate recognition, and gunshot detection technology. These systems currently
use cellular technology, which requires a monthly data plan.
The first of the two gunshot detection technologies is the Flock Raven Gunshot Detection system.
The Flock Raven system costs $50,000 per square mile of coverage for a two-year lease. The
Flock Raven system we are purchasing was funded through a Texas Anti -Gang (TAG) grant. The
areas identified for the deployment of the Flock Raven system also currently have Flock cameras
and city PTZ cameras. The Flock and PTZ cameras work in conjunction with the Flock Raven
system to collect suspect vehicle leads. Flock Ravens do not need a power source as they are
self -powered via solar panels which allows them to be deployed anywhere. The department's
purchase of Flock Ravens allows for coverage of four square miles, divided into one -square -mile
areas. The Las Vegas Trail Neighborhood Improvement Project (NIP) funds an additional square
mile of coverage. The Las Vegas Trail NIP will also be providing additional cameras and license
plate recognition Flock cameras to support the gunshot detection technology.
The other gunshot detection technology is Acoem Gunshot Detection. Acoem Gunshot Detection
involves purchasing sensors and two years of licensing for $74,818. This technology is also

currently being funded by a Texas Anti -Gang grant. The Acoem system requires a power source,
thus limiting where it can be deployed. Each unit is self-contained and can be independently
deployed. The units are portable, but mounting and sensor configuration will need to be
accomplished with any new deployments. Each sensor will cover 500 feet and the department
currently has nine sensors ordered. The Acoem system is more commonly deployed during
planned mass events or in an area that has a large concentration of violent crime.
The neighborhoods where gunshot detection technology will be installed and deployed will
depend on violent crime and gun crime statistics, population density, funding sources, available
power sources, and existing cameras. Preliminarily we have decided on areas for deployment in
Stop Six, South Riverside near Cobb Park, the Historic Northside west of the Stockyards,
Rosemont near Rosemont Park, and Las Vegas Trail between Cherry Lane and Las Vegas Trail.
Exact areas of deployment will depend on up-to-date crime data when the resources are
acquired.
With the implementation of gunshot detection technology in conjunction with smart streetlights,
our goal is to be able to provide gunshot detection in more places when needed. The result would
be a more effective and efficient approach to the reduction of gun violence. We have not
implemented gunshot technology anywhere in the city, outside of initial testing, so we do not have
any data available to report on that type of flock technology specifically. However, in the last 365
days, we have had 1,992 incidents generated by the Real Time Crime Center that can be
attributed to the department's current Flock technology. Of those Flock related incidents, 406
resulted in an arrest. The goal we hope to achieve with gunshot detection technology
implementation is a higher percentage of arrests and successful prosecutions for fatal and non-
fatal shootings in the area where this technology is implemented.
In summary, the City's streetlight infrastructure provides the backbone for smart city technologies.
The two technologies can work independently of each other, but smart streetlights with dedicated
power and the Internet would enable the Police Department to investigate crime more effectively.
If you have any questions about smart streetlight technology, please contact Julius White, Senior
Capital Projects Officer for TPW, at julius.white@fortworthtexas.gov or 817-392-7686.
If you have any questions about gunshot detection technology, please contact Deputy Police
Chief David Carabajal at david.carabajal@fortworthtexas.gov or 817-392-4311.
