其实这个所谓的奥秘已经不能再称之为奥秘了，早在05年的时候网上就已经暴出了这个问题。就是通过google，我们能找出很多网络摄像机，查看并操作。甚至很多需要密码的，可以绕过密码的连接查看并控制。原理十分简单，利用google hack——通过特定关键词，让google返回我们想要的结果 。具体操作如下：

打开google，输入下面的任意一行，从返回的结果中，打开就行了。其中命中率比较高的几个关系词为：

 1nurl:ViewerFrame?Mode=（摄像头由Panasonic公司生产）
 2intitle:"Live View / - AXIS" | inurl:view/view.shtml
 3inurl:indexFrame.shtml Axis（摄像头由瑞典Axis Communications公司制造）
 4intext:"MOBOTIX M1" intext:"Open Menu"（其他品牌的摄像头）
 5intitle:"WJ-NT104 Main Page（其他品牌的摄像头）
 6intitle:"Live View / - AXIS" | inurl:view/view.shtml
 7inurl:indexFrame.shtml Axis
 8intitle:"Live View / - AXIS"
 9intext:"MOBOTIX M1" intext:"Open Menu"
10inurl:"ViewerFrame?Mode="
11intitle:"WJ-NT104 Main Page"
12intitle:snc-rz30 inurl:home/

注：上面括号中的内容不要输入。

另外网上还流传一个所谓的完全版，内容如下：

而通过对关键词搜索得出的结果来看，之前网上流传的所谓这样的“无主摄像机”有几万个的说法并不夸张。其中axis公司的占比最多，日本的几家数码的公司点比次之。不过大多为一些老旧的设备。清晰度上并十分高。像目前一些新兴的网络摄像机，安全保护做的都十分好，一般不会存在这样的问题。如webcam和产品结合的较好的dlink的mydlink 网络摄像机等需要通过用户和密码认证才行，而另外一些其网络摄相机产品不支持web直接访问，需要客户端软件才行。

最后不得不说下，也许我们真的从未了解过google的强大。
