作者:卓绍彩
摘要
当今社会,随着生活节奏的不断加快,电子电器的飞速发展,给广大群众及家庭带来了很大的方便,很多高档住宅都配备着各式各样的高档家具及电器以及贵重物品。正因如此,这也成了一些不法分子的经常犯罪场所。应此,很多居民都在为防盗而苦恼。报警器在这个时候就成为了防盗的利器,但市场上的报警器各有个样,可信度也各有千秋,经常出现误报的现象。出现误报主要有以下几个方面原因:红外探测器易受温度、光线等环境因素影响而产生误报;红外探测器对入侵行为判断力不够准确造成误报;也有些报警器的质量太差,如元器件的损坏和生产工艺不良造成误报;还有跟选择的设备、安装的方式、角度、位置、也有关;还有人为的因素主要有用户操作不当、不小心触发报警器、误闯、误入已经设防的访区等都会产生误报。
