过去数年中人们对声频复核报警的好处宣传可谓多矣,毫无疑问这项技术对减少误报警出动和确认出现场犯罪的发生都取得了惊人的成就。 然而至今这些好处却由于两主要问题而没有什么体现。 1.以往的报警确认系统成本昂贵; 2.必须更换服务良好的现有设备才能取得声音检验技术带来的好处。 ……毫无进展！ In the past few years, there has been a lot of publicity about the benefits of audible and visual alarms. There is no doubt that this technology has made amazing achievements in reducing false alarms and confirming the occurrence of crimes in the field. However, these benefits so far have not been reflected by two major problems. 1. Previous alarm validation systems were expensive; 2. The benefits of sound inspection techniques had to be achieved by replacing existing well-serviced equipment. ……no progress!
