为什么上海地铁站出口安装16个摄像头？官方回应来了
近日，上海地铁7号线耀华路站4号出口因安装16个摄像头引发网络热议。网友拍摄的照片显示，这些摄像头密集分布在闸机上方，部分甚至朝向同一方向。
Shanghai Metro Line 7's Yaohua Road Station Exit 4 recently went viral online for installing 16 surveillance cameras. Photos show clusters of cameras above ticket gates, some pointing in identical directions.
针对公众质疑，上海轨交部门作出官方回应：
Shanghai Metro authorities provided this official explanation:
1. 设备更新过渡期
目前正在进行高清监控系统改造，新旧设备同时运行属于临时现象。新设备调试完成后将拆除旧设备。
1. Equipment Transition Period
The station is undergoing HD surveillance system upgrades. The coexistence of old and new devices is temporary. Obsolete equipment will be removed after new system testing.
2. 安全标准要求
根据上海市《城市轨道交通安全技术防范系统要求》，重点区域需满足：
• 清晰捕捉面部特征
• 视频存储≥90天
• 24小时不间断监控
2. Security Standards Compliance
Per Shanghai's Urban Rail Transit Security Technical Requirements, key areas must:
• Clearly capture facial features
• Store footage ≥90 days
• Maintain 24/7 surveillance
3. 重点监控区域
该出口为闸机集中区域，属于安防重点位置。类似情况也出现在10号线邮电新村站等站点。
3. High-Security Zone
This exit is a ticket gate cluster requiring enhanced surveillance. Similar setups exist at Youdian Xincun Station (Line 10) and other locations.
专家表示，地铁安防系统升级是国际趋势。伦敦地铁平均每个站台安装12-15个摄像头，纽约地铁关键区域摄像头密度更高。
Experts note that metro security upgrades are a global trend. London Underground platforms average 12-15 cameras each, while New York subway critical areas have even higher densities.
