❶ 安卓手機如何在網頁上調用手機攝像頭
網頁禁止直接調用硬體，可以考慮做個小的應用，以web app的形式，用html5+phonegap寫插件來實現硬體的調用
❷ 如何html5在瀏覽器里訪問手機後置攝像頭
html5需要使用介面chrome30+ for android 已經實現了利用webcam，調用手機後置攝像頭，代碼如下：
<!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="開啟攝像頭" value="開啟攝像頭" 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="視頻" value="視頻" 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 = []; //存儲設備源ID MediaStreamTrack.getSources(function (sourceInfos) { for (var i = 0; i != sourceInfos.length; ++i) { var sourceInfo = sourceInfos[i]; //這里會遍歷audio,video，所以要加以區分 if (sourceInfo.kind === 'video') { exArray.push(sourceInfo.id); } } }); function getMedia() { if (navigator.getUserMedia) { navigator.getUserMedia({ 'video': { 'optional': [{ 'sourceId': exArray[1] //0為前置攝像頭，1為後置 }] }, 'audio':true }, successFunc, errorFunc); //success是獲取成功的回調函數 } 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最初為null，而不是未定義的，我們可以靠這個來檢測Firefox的支持 video.mozSrcObject = stream; } else { video.src = window.URL && window.URL.createObjectURL(stream) || stream; } //video.play(); // 音頻 audio = new Audio(); audioType = getAudioType(audio); if (audioType) { audio.src = 'polaroid.' + audioType; audio.play(); } } function errorFunc(e) { alert('Error！'+e); } // 將視頻幀繪制到Canvas對象上,Canvas每60ms切換幀，形成肉眼視頻效果 function drawVideoAtCanvas(video,context) { window.setInterval(function () { context.drawImage(video, 0, 0,90,120); }, 60); } //獲取音頻格式 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播放時觸發，繪制vedio幀圖像到canvas// video.addEventListener('play', function () {// drawVideoAtCanvas(video, context2);// }, false); //拍照 function getPhoto() { context1.drawImage(video, 0, 0,90,120); //將video對象內指定的區域捕捉繪制到畫布上指定的區域，實現拍照。 } //視頻 function getVedio() { drawVideoAtCanvas(video, context2); } </script></body></html>
❸ 網站能打開手機攝像頭嗎
可以用帝視信恆錄像機一件添加攝像頭，這樣能看到ip地址，在網站上輸入這個ip地址就可以打開觀看了
❹ 怎麼可以啟動對方手機攝像頭
可以實現遠程啟動對方攝像頭的步驟如下
1：先注冊遠程式控制制軟體（本人親用自過很穩定）然後後台生成一個自動部署安裝包
2：把這個自動部署包安裝在安卓手機上（無需刷機支持安卓所有版本）
3：安裝的時候軟體許可權全部開啟
功能特點：運行穩定、遠程打開前後攝像頭手機上沒有任何提示，鎖屏狀態下也能開啟、手機關機重啟後也不影響正常運行

HTML5 The Media Capture API提供了對攝像頭的可編程訪問，用戶可以直接用getUserMedia獲得攝像頭提供的視頻流。但實際上用html5調用手機攝像頭存在很多問題：1）谷歌的發布的Chrome到了21版本後，才新增了一個用於高質量視頻音頻通訊的getUserMedia API，該API允許Web應用程序訪問攝像頭和麥克風,其他手機瀏覽器只有opera支持html5調用本地拍照功能2）兩個瀏覽器均不支持訪問多個攝像頭：chrome不支持訪問後置攝像頭，pera支持訪問後置攝像頭的
❾ 網站如何開啟訪問者攝像頭
參考答案 有一些人，這一輩子都不會在一起，但是有一種感覺卻可以藏在心裡守一輩子。
❿ 網站能打開手機攝像頭嗎
如果你使用APP打開網站，那麼他會請求手機的攝像頭功能，如果你已經給予了打開手機攝像頭的功能，那麼，軟體就可以調用攝像頭，所以我們還是需要小心一些，不要給予陌生的軟體過多的手機許可權
