Cities in Brazil and the UK use face cameras. They want to stop crime and find bad people.

巴西與英國的城市使用面部識別攝影機，旨在阻止犯罪並尋找犯罪分子。

São Paulo has many cameras. The city wants 100,000 cameras by 2028. They want to find missing people. But some people say the cameras do not stop crime.

聖保羅擁有許多攝影機。該市希望在2028年前安裝10萬部攝影機，以尋找失蹤人口。但有些人認為這些攝影機無法阻止犯罪。

In the UK, shops use a system called Facewatch. It tells the police when a thief is in the shop. Some people say this is bad for privacy.

在英國，商店使用一套名為Facewatch的系統。當小偷進入商店時，該系統會通知警方。有些人認為這對隱私不利。

These cameras often make mistakes. In Brazil and the UK, the cameras often stop Black and Asian people by mistake. Also, these systems cost a lot of money.

這些攝影機經常出錯。在巴西與英國，攝影機經常誤將黑人與亞裔人士攔截。此外，這些系統的成本非常高昂。

Governments want more security. But many people say these cameras are not fair.

政府希望加強安保，但許多人認為這些攝影機並不公平。

Local governments and private companies in Brazil and the United Kingdom have introduced large facial recognition networks to improve public safety and prevent theft in stores.

巴西與英國的地方政府及私人公司引入了大型人臉辨識網路，旨在提升公共安全並防止商店盜竊。

In São Paulo, the 'Smart Sampa' project has installed 50,000 cameras, with plans to reach 100,000 by 2028. This system connects public cameras with private sensors to find missing people and criminals. Officials claim this is necessary due to high crime rates; however, the Centre for Security and Citizenship Studies (CESeC) emphasizes that there is no clear drop in murders or thefts. They argue that because organized crime has become more professional, simple street surveillance is less effective.

在聖保羅，「Smart Sampa」計畫安裝了 50,000 支攝影機，並計劃在 2028 年前達到 100,000 支。此系統將公共攝影機與私人感測器連接，用於尋找失蹤人口與罪犯。官員聲稱由於犯罪率高，此舉是必要的；然而，安全與公民研究中心 (CESeC) 強調，謀殺或盜竊案並沒有明顯下降。他們認為，由於有組織犯罪已變得更加專業，單純的街道監控效果已然降低。

Similarly, the UK retail sector uses a system called 'Facewatch' to alert police when repeat offenders are spotted in shops. While the British Retail Consortium asserts that rising crime caused this change, civil rights groups argue that it is an unfair violation of privacy. Furthermore, there is a legal gap because the rules for police use of biometrics may not apply to private businesses.

同樣地，英國零售業使用一套名為「Facewatch」的系統，當在商店發現慣犯時會通知警方。雖然英國零售聯盟主張犯罪率上升導致了這一改變，但民權團體認為這是對隱私的不公平侵害。此外，由於警方使用生物辨識的規則未必適用於私人企業，因此存在法律漏洞。

Both countries face serious criticism regarding racial bias and technical errors. In Rio de Janeiro, reports show that about 80% of wrong arrests caused by facial recognition involved Black citizens. Likewise, evidence from the UK shows higher error rates for Black and Asian people. Consequently, critics argue that the huge spending on these systems—such as Rio's 670 million reais investment—wastes money that should be used for public services and legal reforms.

兩國在種族偏見與技術錯誤方面均面臨嚴重批評。在里約熱內盧，報告顯示約 80% 因人臉辨識導致的誤捕涉及黑人公民。同樣地，來自英國的證據顯示，黑人與亞洲人的錯誤率較高。因此，批評者認為在這些系統上的巨額支出——例如里約投資的 6.7 億雷亞爾——浪費了應當用於公共服務與法律改革的資金。

The current situation shows a conflict between governments trying to provide security and the growing opposition from legal and civil rights groups.

目前的情況顯示，政府嘗試提供安全保障與法律及民權團體日益增加的反對聲音之間存在衝突。

Municipal and private entities in Brazil and the United Kingdom have implemented expansive facial recognition networks to enhance public security and retail loss prevention.

巴西與英國的市政與私人機構已實施大規模的面部識別網絡，以強化公共安全與零售業防止損失。

In São Paulo, the 'Smart Sampa' initiative has established a surveillance apparatus comprising 50,000 cameras, with projected expansion to 100,000 by 2028. This system integrates public infrastructure with privately owned sensors to identify fugitives and missing persons. The adoption of such technology is attributed to persistent public insecurity and the repurposing of pandemic-era monitoring tools. However, the efficacy of this deployment is contested; the Centre for Security and Citizenship Studies (CESeC) reports no discernible reduction in homicides or thefts, noting that the shift toward sophisticated organized crime conglomerates renders street-level surveillance less effective.

在聖保羅，「Smart Sampa」計畫建立了一套包含 50,000 支攝影機的監控裝置，預計到 2028 年將擴展至 100,000 支。該系統將公共基礎設施與私人感測器整合，用以識別逃犯與失蹤人口。採用此類技術歸因於持續的公共不安全感以及對疫情時期監控工具的重新利用。然而，此次部署的成效存在爭議；安全與公民研究中心 (CESeC) 報告指出，謀殺或盜竊案並無明顯減少，並 noting 隨著組織犯罪集團趨向精細化，街道層級的監控效果已然降低。

Parallel developments are evident in the United Kingdom's retail sector via the 'Facewatch' system. This technology enables real-time alerts to law enforcement upon the identification of recidivist offenders. While the British Retail Consortium cites escalating retail crime as a catalyst, civil liberties organizations argue that such measures constitute a disproportionate infringement on privacy. A critical point of contention is the regulatory disparity between public and private sector applications of biometrics, as proposed legal frameworks for police use may not extend to commercial entities.

英國的零售業亦透過「Facewatch」系統展現出平行發展。此技術可在識別出累犯時，向執法部門發出即時警報。儘管英國零售聯盟將零售犯罪升溫視為催化劑，但公民自由組織認為此類措施構成了對隱私的不成比例侵犯。一個關鍵的爭議點在於生物識別在公共與私人部門應用之間的監管差異，因為針對警方使用的擬議法律框架可能並不延伸至商業實體。

Both jurisdictions face significant critiques regarding algorithmic bias and systemic inaccuracy. In Rio de Janeiro, reports indicate that approximately 80% of erroneous arrests linked to facial recognition involved Black citizens. Similarly, evidence from the UK suggests higher misidentification rates for Black and Asian populations. Furthermore, the high fiscal expenditure on these systems—exemplified by Rio de Janeiro's 670 million reais investment—is viewed by critics as an opportunity cost that diverts resources from essential public services and fundamental judicial reform.

兩個司法管轄區均面臨關於演算法偏差與系統不準確的嚴重批評。在里約熱內盧，報告指出約 80% 與面部識別相關的錯誤逮捕涉及黑人公民。同樣地，來自英國的證據顯示黑人與亞裔人口的誤認率較高。此外，這些系統的高額財政支出——例如里約熱內盧 6.7 億雷亞爾的投資——被批評者視為機會成本，分散了本應投入於基本公共服務與根本司法改革的資源。

The current landscape is characterized by a tension between institutional efforts to project security and growing judicial and civil opposition to biometric surveillance.

目前的局勢呈現出機構試圖展現安全性，與司法及公民對生物識別監控日益增長的反對之間存在緊張關係。
