United States cities actively install a sound monitoring system: privacy controversy-monitor, terrorism-IT information

Information on IT due to issues such as counter-terrorism needs, United States cities were positive installing sound listening systems for public transportation systems deployment, but the moves have caused a lot of public dispute over privacy protection.

However the opposition seems to be not enough to affect the Government's decision now, New Hampshire, Connecticut, Maryland, Michigan, Ohio, Nevada, Oregon, and California cities have already installed or are preparing to install such a device. In Maryland's public transportation system, for example, 65% of 82% Metro buses and sound recording capability.

However, such initiatives are not all across the United States to promote, for example, New Jersey was ready to deploy a Metro system monitoring equipment, but because the opposition is too large, resulting in the Metro canceled the project. But the overall trend, if the United States has not improved the security situation, the move probably will continue to promote it.

美国城市积极安装声音监听系统：隐私保护惹争议 - 监听,反恐 - IT资讯

IT资讯讯 由于反恐等问题的需要，美国多个城市都积极安装部署公共运输系统的声音监听系统，但这一举措引发了很多民众对于隐私保护问题的争议。

然而这些反对声似乎不足以影响政府决策，目前马里兰州、新罕布什尔州、康涅狄格州、密歇根州、俄亥俄州、内华达州、俄勒冈州和加利福尼亚州的各个城市都已经安装或者正准备安装此类设备。例如在马里兰州的公共交通系统中，65%的公交车和82%的地铁有声音记录能力。

不过这种举措也并非全美都能推广，例如新泽西州本来准备在地铁系统部署这一监控设备，但由于反对声浪过大，导致地铁部门取消了该项目。但从整体趋势来看，如果美国的安全形势没有好转，这一举措恐怕还会继续推进下去。
