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

3.下载大华网络摄像头OCX包，下载地址http://download.csdn.net/detail/whzhaochao/5965005

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

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
