ASAP/ALPR GUIDELINES
PURPOSE
The purpose of this station order is to establish procedural guidelines and responsibilities for personnel to properly utilize and document hits and/or arrests derived from the fixed !Automatic License Plate Reader (ALPR) cameras and Automated Surveillance and Protection (ASAP) units in the Carson Station area.
BACKGROUND
ALPR is a computer-based system that utilizes special cameras to capture a color image, as well as an infrared image, of the license plate of a passing vehicle. The plate is automatically run to see if it is stolen, or has any other wants/warrants associated with it. If a match is found, the user is notified of the vehicle "hit" by an audible alert and an associated notation on the user's computer screen.
GENERAL GUIDELINES
Mobile ALPR unit users receiving an alert that a vehicle is stolen, wanted, or has a warrant associated with it shall immediately confirm the status of the vehicle by running the license plate either manually via the MDC/CAD or over the radio via SCC, unless compelling circumstances are present or officer safety issues make it unsafe to do so. In such cases, deputies shall confirm the status of the wanted vehicle as soon as possible. When requesting SCC to confirm the status of an ALPR hit, the deputy shall advise SCC the request is for an ALPR hit on a vehicle. In the case of a stolen vehicle hit, personnel may regard the vehicle as a known stolen vehicle while awaiting secondary confirmation. If the decision is made to initiate Code 9 operations prior to secondary confirmation, deputies shall request the Duplex Patch and announce their status in a manner similar to the following:
"Carson 163 is Code 9 behind a 10-29V ALPR hit..."
A vehicle pursuit is considered unauthorized until secondary confirmation has been obtained. This is why it is imperative that deputies include "ALPR" verbiage in their initial broadcast.

ALPR TRAILERS
There are three (3) ALPR trailers disguised as temporary roadside digital speedometer warning signs (alerting passing motorists of their speeds). Their placement throughout Carson's patrol area is at supervisor discretion or upon the recommendation of any sworn personnel. Placement of the trailers shall be logged in dispatch in a conspicuous location such as a grease board. The oncoming watch commander shall be notified of their location. The watch commander will ensure ALPR trailer locations are disseminated to all field personnel.1
DESK PERSONNEL RESPONSIBILITIES
- The Watch Deputy and Dispatcher shall insure the Target Alert System (TAS) is activated and enabled at all times
throughout their shift.
- In the event a hit is verified for a 10-29V, high bail or felony warrants, or Amber Alerts, the information shall be
relayed to the patrol units without delay.
- As soon as practical, a call shall be generated for documentation purposes. If the information is relayed via L-TAC,
and the vehicle is not located, an OBS shall !be generated by the desk and cleared if a patrol unit has not already done so.
- All Call/OBS generated from the fixed ALPR cameras shall be cleared with the stat code 836, even if the
targeted vehicle is not located. It is imperative we accurately record these hits to track the effectiveness
of the system for statistical purposes.
Please ensure the following stat codes are used:
835 - ASAP - ALPR/MOBILE
836 - ASAP - ALPR/FIXED CAMERA
Any incident associated with the ALPR system shall be documented using a secondary ALPR statistical code. The statistical code shall be written in the box on the top of the Incident Report (SH-R-49) and in the MDT clearance. ALPR statistical codes cannot be used for the issuance of an URN number, but shall be used as a secondary statistical clearance code only.
