❶ 安卓手机如何在网页上调用手机摄像头
网页禁止直接调用硬件，可以考虑做个小的应用，以web app的形式，用html5+phonegap写插件来实现硬件的调用
❷ 如何html5在浏览器里访问手机后置摄像头
html5需要使用接口chrome30+ for android 已经实现了利用webcam，调用手机后置摄像头，代码如下：
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head> <title>HTML5 GetUserMedia Demo</title> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0" /></head><body> <input type="button" title="开启摄像头" value="开启摄像头" onclick="getMedia();" /><br /> <video height="120px" autoplay="autoplay"></video><hr /> <input type="button" title="拍照" value="拍照" onclick="getPhoto();" /><br /> <canvas id="canvas1" height="120px" ></canvas><hr /> <input type="button" title="视频" value="视频" onclick="getVedio();" /><br /> <canvas id="canvas2" height="120px"></canvas> <script type="text/javascript"> var video = document.querySelector('video'); var audio, audioType; var canvas1 = document.getElementById('canvas1'); var context1 = canvas1.getContext('2d'); var canvas2 = document.getElementById('canvas2'); var context2 = canvas2.getContext('2d'); navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia; window.URL = window.URL || window.webkitURL || window.mozURL || window.msURL; var exArray = []; //存储设备源ID MediaStreamTrack.getSources(function (sourceInfos) { for (var i = 0; i != sourceInfos.length; ++i) { var sourceInfo = sourceInfos[i]; //这里会遍历audio,video，所以要加以区分 if (sourceInfo.kind === 'video') { exArray.push(sourceInfo.id); } } }); function getMedia() { if (navigator.getUserMedia) { navigator.getUserMedia({ 'video': { 'optional': [{ 'sourceId': exArray[1] //0为前置摄像头，1为后置 }] }, 'audio':true }, successFunc, errorFunc); //success是获取成功的回调函数 } else { alert('Native device media streaming (getUserMedia) not supported in this browser.'); } } function successFunc(stream) { //alert('Succeed to get media!'); if (video.mozSrcObject !== undefined) { //Firefox中，video.mozSrcObject最初为null，而不是未定义的，我们可以靠这个来检测Firefox的支持 video.mozSrcObject = stream; } else { video.src = window.URL && window.URL.createObjectURL(stream) || stream; } //video.play(); // 音频 audio = new Audio(); audioType = getAudioType(audio); if (audioType) { audio.src = 'polaroid.' + audioType; audio.play(); } } function errorFunc(e) { alert('Error！'+e); } // 将视频帧绘制到Canvas对象上,Canvas每60ms切换帧，形成肉眼视频效果 function drawVideoAtCanvas(video,context) { window.setInterval(function () { context.drawImage(video, 0, 0,90,120); }, 60); } //获取音频格式 function getAudioType(element) { if (element.canPlayType) { if (element.canPlayType('audio/mp4; codecs="mp4a.40.5"') !== '') { return ('aac'); } else if (element.canPlayType('audio/ogg; codecs="vorbis"') !== '') { return ("ogg"); } } return false; } // vedio播放时触发，绘制vedio帧图像到canvas// video.addEventListener('play', function () {// drawVideoAtCanvas(video, context2);// }, false); //拍照 function getPhoto() { context1.drawImage(video, 0, 0,90,120); //将video对象内指定的区域捕捉绘制到画布上指定的区域，实现拍照。 } //视频 function getVedio() { drawVideoAtCanvas(video, context2); } </script></body></html>
❸ 网站能打开手机摄像头吗
可以用帝视信恒录像机一件添加摄像头，这样能看到ip地址，在网站上输入这个ip地址就可以打开观看了
❹ 怎么可以启动对方手机摄像头
可以实现远程启动对方摄像头的步骤如下
1：先注册远程控制软件（本人亲用自过很稳定）然后后台生成一个自动部署安装包
2：把这个自动部署包安装在安卓手机上（无需刷机支持安卓所有版本）
3：安装的时候软件权限全部开启
功能特点：运行稳定、远程打开前后摄像头手机上没有任何提示，锁屏状态下也能开启、手机关机重启后也不影响正常运行

HTML5 The Media Capture API提供了对摄像头的可编程访问，用户可以直接用getUserMedia获得摄像头提供的视频流。但实际上用html5调用手机摄像头存在很多问题：1）谷歌的发布的Chrome到了21版本后，才新增了一个用于高质量视频音频通讯的getUserMedia API，该API允许Web应用程序访问摄像头和麦克风,其他手机浏览器只有opera支持html5调用本地拍照功能2）两个浏览器均不支持访问多个摄像头：chrome不支持访问后置摄像头，pera支持访问后置摄像头的
❾ 网站如何开启访问者摄像头
参考答案 有一些人，这一辈子都不会在一起，但是有一种感觉却可以藏在心里守一辈子。
❿ 网站能打开手机摄像头吗
如果你使用APP打开网站，那么他会请求手机的摄像头功能，如果你已经给予了打开手机摄像头的功能，那么，软件就可以调用摄像头，所以我们还是需要小心一些，不要给予陌生的软件过多的手机权限
