Police staff reported that, during the reporting period, the license‑plate‑reader hot list produced about 57,000 hits on vehicles of interest and more than 42,000 hits classified as stolen plates. An investigator overseeing major cases told the board LPR results are “100% useful” and said the technology has been integrated into routine patrol and investigative workflows. “I could say with confidence that license plate readers have helped solve a majority of our homicide cases,” the presenter said.

Board members asked whether the large counts include duplicate reads — for example, the same plate captured multiple times across the city — and police confirmed duplicates are included in those totals. Members also noted the department faces data‑volume challenges similar to those discussed for Raven: high numbers of alerts can exceed immediate processing capacity.

Police characterized LPRs as valuable for follow‑up and investigative leads, for tracing vehicles associated with crimes and for locating stolen vehicles or vehicles with stolen plates. No policy changes or new procurement decisions were made at the meeting; the report was provided for board review and questions.

Less critical: the department also said the monthly technology packet includes usage metrics for the drone program, cell‑site simulator, ALPR, FLOP and Raven and invited board members to submit questions if they want more detail.","mediaType","Video","parentTitle","Surveillance Advisory Board - Special Meeting - August 21, 2025","oneSentenceSummary","At the board’s monthly technology briefing police said automatic license plate readers generated roughly 57,000 'hot list' hits this year and more than 42,000 stolen‑plate hits; presenters said LPR data are routinely used by patrol and investigations and have helped with homicide investigations.","taxTitle","Vallejo, Solano County, California","taxId",5493,"location","headline","","shortSummary",{"_33":76,"_35":36,"_37":38,"_39":77,"_41":78,"_43":79,"_45":80,"_47":81,"_49":82,"_51":83,"_53":84,"_55":56,"_57":58,"_59":85,"_61":62,"_63":64,"_65":86,"_67":68,"_69":70,"_71":68,"_72":73,"_74":73},6135978,"Vallejo surveillance board appoints ad hoc work‑plan committee; separate tower policy committee to be formed",202,2242000,2444000,"/Search/View?dp=1&key=5670908-8bf4cf5000fdba2e0c8f6482f1cad9f2&start=2242&end=2444","https://assets.pipeline.soar.com/5670908-8bf4cf5000fdba2e0c8f6482f1cad9f2/thumbnail_2242000.jpg","/articles/6135978/Vallejo/Solano-County/California/Vallejo-surveillance-board-appoints-ad-hoc-workplan-committee-separate-tower-policy-committee-to-be-formed","https://secure.pipeline.soar.com/6135978-8af6e9b30f6a2a129e0199f87f4250ed/orig.mp4?Expires=1771120642&Signature=OJnAQvKAU0yzJBOK222rrEDPC5NHATTgv0M56gdObS5O-R7bPkTyGjttYB06VpsdFIXUM0x-cT8GX1oa34mK1hlqKJjNFTA3A3FKTdrOOhn1fGX~DKMPGCT5Tdq0hvOKGkj3mholuaLI7DYj~9t1NrMXq9MoUJeM0xWAb7U-1oWup-nR9eoOJAHzrFkqCzJB5YwlVHYVS59bTHQez4xSkENogx~Kzg93~WeQQxpNPLMAtoz8RE5xjsMVdHCrsVMMuPFRtyoBkQjodIrAsE1DCvHF6HVS60RZ~PkCBCZcIses2Wv-F2D8HBpyCzEpNKMzbkBRBdHQ5aRdIDLBNObs2w__&Key-Pair-Id=KUT5TJCACFTXG","The Vallejo Surveillance Advisory Board voted to form an ad hoc subcommittee to draft a work plan for the board’s work.

Chair Lee accepted nominations and Board Member Stewart was nominated and agreed to serve. Two other board members volunteered; the board then held a roll call to approve the subcommittee. The motion passed by roll call with members voting yes, and the board recorded the motion as passed.

Board members clarified the limits and purpose of the ad hoc committees. City Attorney Reisner explained ad hoc committees must have a single distinct purpose and be time‑limited. The board discussed that the surveillance tower technology‑use policy would be drafted by a separate ad hoc committee; the same board members may be appointed to that separate committee at a later meeting.

The board scheduled the next regular meeting for the third Thursday and said it will agendize appointment of the surveillance tower policy committee at a future meeting. No formal policy language was drafted at this meeting; the action was limited to appointing the work‑plan subcommittee and confirming that a distinct committee for tower policy would be considered later.

Less critical: that the earlier volunteer list from the previous meeting was discussed, and some members sought clarification about why this item was agendized again; staff said the current meeting was the formal agendized vote.","The Surveillance Advisory Board appointed an ad hoc subcommittee to draft a work plan and agreed members of that subcommittee may also be appointed to a separate, distinct ad hoc committee to draft a surveillance tower technology‑use policy at a future meeting.",{"_33":88,"_35":36,"_37":38,"_39":89,"_41":90,"_43":91,"_45":92,"_47":93,"_49":94,"_51":95,"_53":96,"_55":56,"_57":58,"_59":97,"_61":62,"_63":64,"_65":98,"_67":68,"_69":70,"_71":68,"_72":73,"_74":73},6135980,"Vallejo advisory board recommends city pursue Flock Raven gunshot‑detection system",721,481000,1202000,"/Search/View?dp=1&key=5670908-8bf4cf5000fdba2e0c8f6482f1cad9f2&start=481&end=1202","https://assets.pipeline.soar.com/5670908-8bf4cf5000fdba2e0c8f6482f1cad9f2/thumbnail_481000.jpg","/articles/6135980/Vallejo/Solano-County/California/Vallejo-advisory-board-recommends-city-pursue-Flock-Raven-gunshotdetection-system","https://secure.pipeline.soar.com/6135980-eda66a88b40a6a7a65b2d93763b33086/orig.mp4?Expires=1771120642&Signature=jfnmOmN0qrJGNHoFOc61QsBCLKQaBadwN9q1nK6y56lMW4gxeR3LXhyumZyUgDiRpSdOotePcvQa3Mzy1-Lj2y1vxsK-wB2evBqiCo1tMo8LB29RcbRbgKScOTXRqkSC2ghsUZkjHzX39KvnKyBB0Sl6GD1cBY3A7PYw6P9gKPHNzcTJq284Ro00CcEsr5HiAIULK9SQkLTj9F8bA5xPefSg8tfzckrbpYr4R3fUqU8bmQuEBy2GQOPFFuATgOyoylYvFIlw8v~FIU5q7jjdf3MMFhpn-GpOfIp0XCXq2t~-JKBDUg2f-i46WlaBJUI15fZTDhlgGoD8QLKGhAMyvA__&Key-Pair-Id=KUT5TJCACFTXG","The Vallejo Surveillance Advisory Board voted to recommend that the City Council consider using Flock Raven, a gunshot‑audio detection system, after a presentation by police staff about a beta test of the technology.

The board’s recommendation followed a presentation by Captain Bautista, who described Raven as “gunshot audio detection technology” and said the department ran training in June and September, began beta testing on Sept. 6 and implemented Raven with dispatch on Sept. 11. “My recommendation would be to move forward with the technology of, Flock Raven,” Bautista said.

Board members discussed the system’s operational benefits and limits. The department reported 1,003 Raven alerts from Sept. 6 through July 31 and 342 separate shots‑fired incidents during the same period. Combined, the department recorded 1,345 shooting alerts and incidents and said 99 investigative cases were generated from those data points — 26 traced to Raven alerts and 73 to caller‑reported shots. Police said 37 incidents had both a Raven alert and a 911 shots‑fired call; in 21 of those incidents officers located a scene within five minutes after a Raven alert, and in five cases Raven helped locate a scene after a gunshot‑wound victim walked into a hospital and could not give a location.

Police staff and dispatch staff described how Raven alerts are reviewed and entered into the city’s computer‑aided dispatch (CAD) system. The department said Raven is not integrated with CAD, and early in the beta not all Raven alerts were entered as separate 10‑75R shots‑fired incidents. Dispatchers receive Raven notifications on a separate console and, when possible, input an approximate location into dispatch. The department said priority and officer response depend on whether a 911 caller also reports shots; a confirmed 911 shots‑fired report will typically elevate the call to a priority‑1 response.

Presenters described the criteria the department uses to label an alert confirmed: a gunshot‑wound victim on scene, physical observation of shots, surveillance video, or physical evidence such as casings or strike marks. The department stressed that an alert labeled “unconfirmed” does not necessarily mean no gunfire occurred.

Board members pressed on data quality, coverage and placement. One board member warned that Raven sensors were not randomly sited but placed where police anticipated violence, a pattern the member said could be “self‑reinforcing” and resemble predictive policing. Police replied the beta used a limited number of sensors chosen from prior gunshot‑analysis and that additional sensors would be needed for citywide coverage. The department also said multiple Raven alerts can result from multiple volleys in a single incident and that triangulation of clustered sensors is used to locate events rather than counting a single gunshot as multiple independent events.

Members asked how often Raven alerts have directly solved homicides. Police staff said Raven alerts alone do not solve homicides but that Raven has supported investigations by identifying additional locations where casings were found, tracking movements of suspect vehicles and corroborating information from other agencies. Bautista said the department had “at least 50 confirmation stories” fitting the stated confirmation criteria and emphasized the operational time savings Raven produces for patrol.

A motion to recommend the City Council consider the use of Flock Raven was made and approved in a roll call vote; four board members voted yes and the chair recorded an abstention. City Attorney Reisner read the request as “that the Surveillance Advisory Board make a recommendation to the Vallejo City Council concerning the use of Flock and gunshot detection technology.”

The board’s recommendation will go to the City Council for a final decision. The department said further work is needed to expand coverage, improve CAD integration and refine dispatch handling and confirmation procedures.

Less critical details: the department presented heat maps showing high concentrations of Raven alerts in sections of North Vallejo — identified in the presentation as Country Club Crest and the Cimarron Hills — parts of central Vallejo west of Highway 80 and a southern area identified in the presentation as South Palleo. Police said the heat maps reflected alerts accumulated during the beta period rather than a fully citywide deployment and declined to share a citywide heat map publicly because it would reveal Raven locations.","After a July–September beta, the Surveillance Advisory Board voted to recommend the Vallejo City Council consider adopting Flock Raven. Police presenters cited faster scene location and investigative leads; board members raised coverage, confirmation rates and potential for self‑reinforcing deployments.","actionData","errors"]
