细思有点恐，家里的摄像头好像被黑了去年家里开始了双职工加女佣带娃的模式，所以决定装个摄像头。强迫症受不了拉电线，于是找了个私人公司装了个固定的--就是没有明线，墙上挖了槽埋线进去，而且自带了硬盘等等。两个摄像头，1000多新币，其实主要是人工安装费，比自己买两个小蚁贵多了。这个contractor是我们小区电动门还有门禁系统的vendor, 自称也给各大超市做监视系统的，也算是小有规模。摄像头品牌叫做大华。
之后使用正常，有专门手机App看，而且也是改过密码的，没用default。
这个月突然发现手机app看不了了，显示fail to connect. 简单的重启等动作没用。初步troubleshooting 发现接口的IP完全PING不到，开始还怀疑硬件坏了。今天叫了vendor来修，连上显示器直接进入主机。过程不细说，反正幸好家里有个前network engineer, 跟vendor一通整，发现接口IP被换了。从192.x的IP换成了10.x的外网IP。这就很可疑了。换回192.x的IP后可以连接，显示一切正常摄像头上的小灯也亮了但是屏幕是黑的。又省略无数字的troubleshooting, 发现在image setting 里亮度对比度等全部被设置成0。调高后就正常了。
另外通过log看到IP被改的具体时间是某天早上10点。再回放那天当时的录像，女佣正在扫地，家里� (more...)
刚看到，转一个：what just needs to be fuck off or die already?
"Internet of things" home camera companies that sell cameras for monitoring your children that require that the video feed be streamed to their servers.
The security implications of this are ridiculous. Remember how people complained about the Kinect putting a camera in your living room? At least that one would require your xbox to be taken over for somebody to spy on you. These cameras constantly upload videos of your household by design. And a quick google search for "camera vulnerability" shows how insecure these things are.
Most of the top amazon results are for this sort of camera, but you can easily get a camera that can stream to your PC or qnap/synology NAS instead. If it's streaming to your LAN only, it doesn't open up so many ludicrous security vulnerabilities. If you set up a home VPN, you can get the same remote access features without paying for their "cloud recording" services.
