VadoHD的视频规格依然只有720p，并且没有光学变焦功能，只支持两倍数字变焦，设备通过USB接口与外界连接。
The camera still shoots at 720p with a fixed optical zoom (but 2X digital) lens and attaches directly through its own USB connector.
另外，您可以选择5x数字变焦，(产生的结果更像数字变焦)和基本的开启 /关闭 /自动闪光设置。
Otherwise, you have options for a 5x digital zoom (which produces results that look like a digital zoom) and basic on / off / auto settings for the flash.
