通过WEB调用大华网络摄像头
1.要调用的大华摄像头为Dahua 大华DH-IPC-HFW2100P-0600B 网络摄像机 (白色)，摄像头外形如下图所示
2.调用效果如下图所示
4.解压OCX包单击文件中的reg.bat注册dll
5.新建index.html关输入以下代码
视频控件body {font-family:"", arial;margin:0 auto; padding:0; }
div,form,img,ul,p {margin: 0 auto; padding: 0; border: 0; overflow:hidden; list-style-type:none; }
h1,h2,h3,h4,h5,h6 { margin:0; padding:0;}

6.保存并用IE打开，请允许加载Active控件，如果不出问题则调用成功
注意事项：
1.SSOcx.SetDeviceInfo("192.168.1.108",37777,0,"admin","admin");注意修改成你的摄像机的IP地址、端口、通道、用户名、密码
2.大华的dll要注册成功，检查有没有注册的方法：打开注册表，搜索classid号，如果有表明OCX控件注册成功，classid号为：30209FBC-57EB-4F87-BF3E-740E3D8019D2
3.改方法试用于IE，其它浏览器不行
4.第一次用IE打开一定要加载控件，如果IE阻止控件会导致调用失败。如果IE阻止加载控件，请在Internet项目->安全->自定义级别 中将ActiveX控件和插件下的所有项都启用
