I. PURPOSE: To provide guidelines on the proper use of License Plate Recognition (LPR)
Systems, commonly known as License Plate Reader systems.
II. POLICY: To provide guidelines for the implementation, installation, training and use of mobile
and stationary License Plate Reader (LPR) technology and equipment to scan, detect, and
identify license plate numbers. The LPR system shall be restricted to legitimate law enforcement
uses for the purpose of furthering law enforcement goals and enhancing public safety to include
but not limited to providing information to officers that will assist in on-going criminal
investigations, crime prevention, crime detection, the apprehension of wanted persons and
stolen vehicles, the recovery of missing and endangered persons and the identification of
unregistered and uninsured motor vehicles.
III. DEFINITIONS:
Alert – An audible and/or visual signal activated upon the read of a license plate by the LPR
system that has not been visually verified by an officer against the photo in the LPR system.
Confirmation – (Confirmed Hit) – A hit by the LPR System that has been validated as active
by NCIC/FCIC/DAVID.
Hot Lists – A list of stolen plates and vehicles entered into the National Crime Information
Center (NCIC) as well as Amber, Silver alerts associated with a vehicle tag, wanted criminals
and others of specific interest to law enforcement that have a vehicle or tag associated to
them. This may also be vehicles entered into the Gainesville Police Department’s local
database, which are the subject of ongoing criminal investigations.
License Plate Reader (LPR) – A specialized system consisting of equipment designed to read,
store, and check license plates. The LPR is commonly mounted to a patrol vehicle and
connected to a computer within the vehicle. However, there are other device configurations
utilized such as stationary/fixed or mobile platform such as a department vehicle or speed
trailer.
Vehicle Mounted – An LPR device mounted to a department owned vehicle where the
vehicle operator receives the “HIT” information.
Mobile Platform – An LPR device that can be moved to specific locations that collects data
autonomously, and that can relay “HIT” information to a deputy, officer, investigator or
dispatcher to\n\n--- Page 2 ---\n\nGAINESVILLE POLICE DEPARTMENT
assist in the resolution of traffic or investigative issues.
Fixed platform – An LPR device that is secured at a specific location to collect data
autonomously. And that can relay “HIT” information to an officer, investigator or dispatcher to
assist in the resolution of traffic or investigative issues, transmitted by cellphone technology.
IV. PROCEDURE
A. Training and Issuance:
1. The vehicle mounted LPR Device, mobile platforms, and LPR databases will
only be issued to Department members who have completed agency approved
training. Documented training may include classroom training, review of
manufacturer’s recommendations, and policy guidelines for use. [CALEA
41.3.9.c]
2. All LPR Devices must be operated and maintained in accordance with the
manufacturer’s recommendations as detailed in the training provided prior to
use.
B. Guidelines for Use: [CALEA 41.3.9.a]
1. License Plate Reader systems, associated equipment and databases are
authorized for official law enforcement purposes only. Any member who misuses
the License Plate Reader equipment and associated databases or data may be
subject to disciplinary action.
2. The License Plate Reader device reads the license plates of moving or parked
motor vehicles using LPR Optical Character Recognition Technology and
compares against a Hot List. Additional features of the LPR system include
searching and flagging vehicles for official investigative purposes.
3. During operation, License Plate Reader “hits” are indicated by an audible and
visual alarm. An LPR “hit” shall not be used as the sole reason for a traffic stop or
enforcement contacts until all provisions contained in this section have been
satisfied. Contact with the vehicle and its occupants will only be made after the
“hit” is confirmed.
i. The member receiving the notification must first visually verify that the
Hot List entry matches the digital image displayed by the LPR. If, for any
reason it does not match, the “hit” will be rejected. If, however, it does
match, the “hit” will be accepted and the member will verify the “hit”
through NCIC/FCIC. Once NCIC/FCIC is confirmed then enforcement
action may be taken, such as a traffic stop.
ii. Unless separate probable cause exists, officers will not stop or detain a
vehicle based solely on a hit from the LPR system which has not been
confirmed.
iii. . After stopping the vehicle and prior to taking action, the violation will
be confirmed via teletype.
iv. Any enforcement or investigative action initiated from the LPR hit
shall be documented.

C. Maintenance and Repair: Any member who learns an LPR, whether fixed, mobile,
or attached to a vehicle becomes inoperative, they shall immediately communicate
this issue with their supervisor. The supervisor will then inform the appropriate
Bureau Commander.
D. Data Security, and Access: Scanned License Plate information is sent to an off site
server that is maintained by the vendor. This server has been authorized by CJIS, NCIC
and FCIC after confirmation that it has met all applicable standards for maintaining,
updating and relaying secure criminal information. For an individual to access this server
the individual must be FCIC certified and complete additional LPR specific training before
access is permitted by Log On and Password. [CALEA 41.3.9.b]
E. Date Storage and Retention: All information gathered and disseminated is located off
site by the LPR Vendor which has met state and federal standards applicable for the
retention of criminal information. The duration of access to scanned data will be (3) three
years. [CALEA 41.3.9.d]
