ANTIOCH, CALIFORNIA — Antioch could soon commit nearly $662,000 to a major expansion and overhaul of the city’s police surveillance technology.
The Antioch City Council is scheduled to consider a $661,687.54 sole-source agreement with Axon Enterprise on Tuesday, August 25. The package would establish 55 fixed automated license plate reader locations, equip six additional patrol vehicles with cameras and mobile plate readers, and provide the police department with 120 licenses for an artificial intelligence assistant.
The proposed contract would run for 49 months, beginning October 1, 2026, and ending October 31, 2030.

Cameras Would Be Installed in Two Phases
Under the proposed rollout, Antioch would deploy 38 fixed Axon Outpost license plate reader locations beginning in 2026. Another 17 locations would be added in 2027.
The city would also purchase six Axon Fleet 3 systems for additional patrol vehicles. Those systems combine in-car video with mobile license plate recognition, allowing cameras on police vehicles to scan plates while officers are on patrol.
Automated license plate readers photograph passing vehicles and extract information including the plate number, time and location. Axon’s system can also record visible details such as a vehicle’s color, make and general type.
Police can compare those records against authorized lists of stolen or wanted vehicles. Investigators can also search historical detections to determine where and when a vehicle was previously recorded.
Antioch already operates fixed license plate readers supplied by Motorola and Flock Safety. According to the council staff report, Motorola is decommissioning its platform, prompting the city to replace and consolidate both existing systems within Axon’s network.
The city reportedly had 17 Flock cameras as of April, meaning the proposed network would represent a substantial expansion of fixed coverage.
No Competitive Bidding Is Proposed
Police officials are recommending that the council approve Axon without a competitive bidding process.
The department already uses Axon Body 4 cameras, Axon Fleet in-car cameras and the company’s Evidence digital evidence system. Staff argues that moving the fixed license plate readers into the same environment would reduce the number of accounts, integrations, training programs and vendor relationships the department must manage.
The city’s municipal code permits sole-source purchases involving unique, proprietary or specifically designed technology.
Funding for the first fiscal year has already been identified within the Police Department’s existing General Fund budget. The proposed payments are:
- $175,403.86 during the 2026-27 fiscal year
- $135,500.04 during 2027-28
- $175,391.87 during 2028-29
- $175,391.77 during 2029-30
Payments after the first year would remain subject to Antioch’s annual budget process.
The AI Assistant Is Primarily Presented as a Translation Tool
The agreement also contains a significant AI component: 120 Axon AI Assistant licenses costing a combined $172,118.40 over the contract term. That represents approximately 26 percent of the package’s total price.
Antioch’s staff report presents the assistant primarily as a real-time translation tool built into the body cameras officers already wear.
An officer would manually activate the feature and use a push-to-talk process to communicate in more than 50 languages, including Spanish, Tagalog, Vietnamese, Arabic, Mandarin Chinese, Hindi and Persian. The system would not passively or continuously listen.
Activating translation would also start the camera’s audio and video recording. The recording would be uploaded to the department’s existing digital evidence system, while supervisors could audit when and for how long the translation feature was used.
Axon cautions that the AI-generated translation is intended for routine interactions such as traffic stops, public assistance and lower-level incident reports. It is not positioned as a substitute for a qualified interpreter during witness interviews, high-stakes incidents or situations requiring certified accuracy.
Axon markets its broader AI Assistant as also offering voice-enabled police policy questions and general question-and-answer capabilities. Antioch’s staff report, however, explains and justifies the 120 licenses solely in terms of translation. It does not specify whether those other AI capabilities would be enabled for Antioch officers.
Privacy Protections Remain a Central Question
License plate readers have helped police recover stolen vehicles and investigate shootings, burglaries, hit-and-run crashes, missing-person cases and illegal sideshows. However, the systems also create searchable records showing where vehicles have traveled.
In April, Antioch Police Lt. Bill Whitaker told ABC7 that the city’s Flock cameras had helped solve 31 felony cases since the previous August and recover thousands of dollars in property.
The proposed Axon system would not use facial recognition, conduct live registered-owner lookups or make enforcement decisions, according to the council report. A camera alert would remain an investigative lead that officers are expected to verify before taking action.
Antioch says its current policy restricts license plate data to legitimate law enforcement purposes. Historical searches must be connected to a specific police case or computer-aided dispatch event and include an investigative reason.
Access would be password-protected, logged and subject to audits. The department also says it will not provide direct or standing access to federal or out-of-state law enforcement agencies.
That restriction is especially significant in California, where state law limits the sharing of license plate data and generally prohibits providing it to federal or out-of-state agencies. Improper sharing by other California departments has fueled growing concern about the technology’s potential use for immigration enforcement and other forms of surveillance.
Axon says Antioch would retain control of its data and that sharing would be turned off unless the department deliberately authorized access for another California law enforcement agency. Searches, exports and sharing decisions would be recorded in audit logs.
Antioch’s current Flock system reportedly retains ordinary plate detections for 30 days. The new staff report does not identify a specific retention period for the replacement Axon network. Axon’s materials say each agency selects its own retention period and that the system automatically deletes non-evidentiary records when that period expires.
The proposal is listed as Item 9 on the Antioch City Council’s August 25 agenda. The regular meeting begins at 7 p.m. in the City Council Chambers at 200 H Street.
