我正在使用 Arduino uno 板、Arduino 以太网屏蔽和 dcs-930L Ip 摄像头以及伺服电机开发安全系统，我的地址是直接从网络浏览器访问视频和照片，我使用以太网屏蔽来设置一个网站，这样我就可以控制它实际工作的伺服器，所以我想做的是设置一个按钮，这样当我点击它时，它会从我的网络摄像头给我一个 video/image 它可以是在同一个 Arduino 网站内或打开另一个 window 浏览器！感谢您的帮助！谢谢

Answer 1

如果您想在网站上添加一个按钮来打开一个新的 window 显示 IP 摄像机提要，您可以使用此 HTML，只需将 PutUrlHere 替换为 URL 的摄像头馈送：

<a href="PutUrlHere" target="_blank">
    <input type="button" value="Show Camera">
</a>

编辑：

对于您的程序，您应该能够在您希望按钮显示的任何地方执行此操作：

client.println("<a href='PutUrlHere' target='_blank'><input type='button' value='Show Camera'></a>");
