路由器在门禁系统中的应用

文章目录 : 其他

在大城市中,无论是高档小区还是民房。大部分已经安装了门禁系统,有的使用身份证或者居住证刷卡进入(通过无线路由器把进入者的信息发送到控制中心存档)。这大大的提高了居住的安全性,减少了盗窃!目前,在一些发达国家中,门禁系统正以远远高于其它类安防产品的进度迅猛发展;门禁系统之所以能在众多安防产品中脱颖而出,根本原因是因为其改变了以往安防产品如闭路监控,防盗报警等被动的安防方式,以主动地控制替代了被动监视的方式,通过对主要通道的控制大大地防止了罪犯从正常通道的侵入,并且可以在罪案发生时通过对通道门的控制限制罪犯的活动范围制止犯罪或减少损失。近年来,GPRS门禁系统由于其自身的优势,已在国内悄然兴起,包括邮电系统,供电系统,银行系统,住宅小区,度假村等各种类型的场所都已有使用门禁系统的范例,通过这套系统的使用极大地提高了管理者的工作效率和管理区域内的安全程度。
