美国多个城市正在停用Flock的自动车牌读取摄像头系统，改为采用执法技术公司Axon提供的替代方案[1]。这一转变的核心驱动力是隐私考量——Axon的自动车牌识别（ALPR）摄像头仅支持机构间的一对一数据共享，而非Flock拥有的全国性查询网络[1]。
从2月开始，城市层面的决定陆续出现[1]。锡拉丘兹市议会以7比1投票支持该市警察局与Axon的合同[1]；3月，丹佛市议会以7比6的微弱多数批准用Axon摄像头替换Flock系统，一年期合同包含50台ALPR摄像头[1]。同月，科罗拉多州朗蒙特市一致投票批准与Axon的新协议[1]。到了年中，威斯康星州格兰德奇特镇投票放弃Flock转向Axon[1]，7月，科罗拉多州道格拉斯县警长办公室签订了近2280万美元的合同，部署100台Axon摄像头[1]。12月，密歇根州费尔代尔市以"隐私问题和Flock未能保护存储在城市ALPR网络上的图像"为由放弃Flock[1]。德州诺克斯维尔市则向现有Axon合同追加940万美元修正案[1]。
两个系统的关键差异在于监控范围[1]。Flock系统的核心功能是提供国家级查询工具，允许警察跨州搜索摄像头数据，而Axon则不具有全国性网络[1]。
Multiple U.S. cities are abandoning Flock's automatic license plate reader (ALPR) system in favor of alternatives from Axon, an enforcement technology company.[1] The shift reflects growing concerns about privacy and data management, as Axon's ALPR cameras, which mount on streetlights or police vehicles to collect license plate data, operate without the nationwide query network that Flock provides.[1] Instead, Axon supports only one-to-one data sharing between agencies, positioning itself as a more privacy-conscious option.[1]
The migration has accelerated across multiple jurisdictions. Syracuse's city council approved a contract between the Syracuse Police Department and Axon in February with a 7-1 vote.[1] Denver followed in March, voting 7-6 to replace its Flock system with 50 Axon ALPR cameras under a one-year agreement.[1] Grand Chute, Wisconsin, abandoned Flock in June to switch to Axon.[1] Douglas County, Colorado, signed a contract with Axon in July for 100 cameras worth nearly $22.8 million.[1] Fairfield, Michigan, made the transition in December, citing "privacy concerns and Flock's failure to protect images stored on the city's ALPR network."[1] Longmont, Colorado, unanimously approved a new Axon agreement in March.[1] Knox, Texas, added a $9.4 million amendment to its existing Axon contract.[1]
The central distinction between the systems lies in their query capabilities: Flock's key feature is a national search tool allowing police to query camera data across state lines, while Axon lacks a nationwide network.[1]
