Knoxville, TN (WOKI / WVLT) – The Knoxville Police Department is responding to community questions and concerns about its use of automated license plate reader technology, commonly known as ALPRs.
In a public statement, Knoxville Police Chief Paul Noel said the department wants residents to have a clear understanding of how the systems work, what information is collected and what safeguards are in place to prevent misuse.
“There has been significant recent public discourse about automated license plate reader cameras, how the technology works, and the safeguards in place to protect privacy and prevent misuse,” Noel said. “Our community deserves clear answers to those questions.”
KPD’s History with License Plate Readers
According to Noel, KPD has been using license plate reader technology for more than a decade.
The department first deployed mobile ALPRs in 2013 and began using fixed ALPR cameras on public roadways in 2021.
Currently, KPD operates:
- 19 fixed Axon ALPR cameras
- 8 additional fixed cameras scheduled for installation in the coming weeks
- 30 mobile ALPR systems integrated into patrol vehicle dashcams across the department’s three patrol districts
How the Technology Works
Noel said there are misconceptions about what ALPR systems are capable of doing.
According to the chief, the cameras take “moment-in-time” photographs of passing vehicles and license plates. He emphasized that the systems:
- Do not record continuous video
- Cannot identify vehicle occupants
- Do not track a vehicle’s movements in real time
Instead, the technology captures license plate information that can be compared against law enforcement databases and investigative leads.
Crime-Fighting and Public Safety Tool
KPD says ALPR systems have become an important investigative resource.
Noel stated that the cameras help officers and detectives:
- Recover stolen vehicles
- Locate wanted individuals and violent offenders
- Generate leads during criminal investigations
- Find missing or endangered people more quickly
Police officials say the technology has contributed to numerous investigations and public safety efforts since being deployed.
Privacy Policies and Oversight
Addressing privacy concerns, Noel said KPD has strict policies governing the use of ALPR technology and the handling of collected data.
The department has published policies outlining system administration, approved uses, data storage and retention requirements. Noel said responsible use and transparency are critical to maintaining public confidence.
“We have strict policies closely regulating the use of our ALPR technology,” Noel said. “Our department is entirely committed to the ethical and transparent use of technology.”
Noel added that KPD’s ability to continue using license plate reader systems depends on public trust, strong safeguards and open communication with the community.
The statement comes as discussions continue across East Tennessee regarding the use of Flock cameras and other automated license plate reader systems by law enforcement agencies.
