Yolo County’s research pass read nine Board of Supervisors agenda items from 2016 through 2026, the Sheriff’s license plate reader policy and its 2024-25 military equipment annual report, the City of Davis surveillance technology renewals packet of June 2024, the City of Woodland’s February 2026 council agenda, minutes and packet along with the police department’s 2025 military equipment annual report, and West Sacramento’s camera registry pages. The City of Davis website, the UC Davis Police Department, West Sacramento’s council records, the City of Winters, the county’s school districts and the vendor behind the Sheriff’s readers could not be read on this pass and remain open.
What's in use here
Davis Police runs license plate readers on parking enforcement vehicles. The council approved the technology in 2016, adopted the use policy in 2018, and reviews it every year. The city's 2024 report describes the system as used for parking enforcement and not shared; the policy also allows checks against national hot lists.
Woodland's council adopted a two-year, $300,000 Flock Safety contract on February 3, 2026 that folds "over 40" cameras bought one at a time into a single agreement. Four cannabis dispensaries reimburse the city $80,000 a year for cameras at their sites.
Board of Supervisors agenda items record a replacement license plate reader in 2016 and $59,000 for two more reader pods in 2018, joining three pods the Sheriff had already bought. No county record we fetched names a vendor, a current count or a location.
Woodland Police's 2025 military equipment report lists eight DJI aircraft across four models and a deployment table whose totals row counts 174 missions in 2024, from warrants and suspect searches to fireworks complaints, graduations and one planned protest.
The Sheriff's military equipment report for October 2024 through September 2025 states 51 drone deployments and lists the office's DJI aircraft by model. The Board of Supervisors approved the office's military equipment use policy and ordinance in November 2022 and took up the renewal in December 2025.
A December 2017 Board of Supervisors agenda item asked for $110,000 of Cannabis Task Force funding to mount an Epsilon 140 camera system on the Sheriff's Aerosquadron plane, with night vision, high definition recording and a real-time feed to deputies on the ground. Nothing in the records we fetched mentions the camera after that item.
West Sacramento Police invites residents and businesses to register private cameras on an Axon Fusus map, with an optional live-video connection that camera owners control.
Who runs it
The agency is the accountability unit: who voted, whose policy applies, and who answers a records request.

| 5 agencies on record. A jointly run system counts against each of its operators, so this column is not a county total. "Posted" means the policy is published where the law requires it. "On file" means we hold the document. "Not posted" and "not found" mean we could not find it on the agency's own website on the date shown; they say nothing about how the system is used. An agency with a dash has not been checked, which is not a finding. | ||||
