[LIGHTS OUT! SH TRAFFICPOLICE TEST NEW CAMERA]

Shanghai police announced the first camera with no light was installed. It was in response to complaints from drivers about digital cameras using bright lights that make it difficult to see at night. 

The surveillance camera was installed at the intersection of two of the city highways. Police said it no longer contains LED lights, but still detects traffic offenses and reads license plates through artificial intelligence, image enhancement and optical technology. The camera has recorded over 160 offenses since early September. Since 2019, Shanghai traffic police have switched 360 cameras to ones with dimmer lights.

夜晚行车，不少车主都曾有被强光电子警察影响视野的体验。为改善车主夜间行车体验，目前，上海交警已研发出了"无光电子警察"，将逐步取代原本刺眼的补光灯，为减少城市光污染再进一步。

晚上八点多，记者来到了逸仙路高架场中路匝道附近，在路况信息板的正上方，一个黑色外壳的摄像头，就是全市首套无光电子警察。与其他设备不同，在摄像头周边，没有较为刺眼的补光灯协助，完全依靠环境光，通过图像的噪点分布信息，识别车身和颜色。9月试点抓拍至今，已捕捉到了160余其违法行为。

实际上，从 2019 年起，上海交警部门已启动 研发新型 电子警察，目前，街面上除了刚刚启用的无灯电子警察以外，去年还更换了 360 套微光电子警察，只利用内置在摄像头内的较弱光源，来实现违法抓拍。
