以下是基于WebRTC技术实现远程实时监控的HTML代码示例:
```html
<!-- 监控端页面 -->
<!DOCTYPE html>
<html>
<head>
<title>远程实时监控 - 监控端</title>
</head>
<body>
<h1>远程实时监控 - 监控端</h1>
<video id="localVideo" autoplay></video>
<button id="startButton">开始监控</button>
<button id="stopButton">停止监控</button>
<script>
var localStream; // 本地视频流
var localVideo = document.getElementById('localVideo');
var startButton = document.getElementById('startButton');
var stopButton = document.getElementById('stopButton');
// 获取摄像头视频流
function getLocalStream() {
navigator.mediaDevices.getUserMedia({ video: true, audio: false })
.then(function(stream) {
localStream = stream;
localVideo.srcObject = stream;
})
.catch(function(error) {
console.log('获取摄像头视频流失败:', error);
});
}
// 开始监控
startButton.onclick = function() {
getLocalStream();
}
// 停止监控
stopButton.onclick = function() {
localStream.getTracks().forEach(function(track) {
track.stop();
});
localVideo.srcObject = null;
}
</script>
</body>
</html>
```
```html
<!-- 远程端页面 -->
<!DOCTYPE html>
<html>
<head>
<title>远程实时监控 - 远程端</title>
</head>
<body>
<h1>远程实时监控 - 远程端</h1>
<video id="remoteVideo" autoplay></video>
<script>
var remoteVideo = document.getElementById('remoteVideo');
// 建立PeerConnection连接
var peerConnection = new RTCPeerConnection();
peerConnection.ontrack = function(event) {
remoteVideo.srcObject = event.streams[0];
}
// 发送视频流到远程端
var sendStream = function(stream) {
stream.getTracks().forEach(function(track) {
peerConnection.addTrack(track, stream);
});
}
// 在监控端发送Offer
var sendOffer = function() {
peerConnection.createOffer()
.then(function(offer) {
return peerConnection.setLocalDescription(offer);
})
.then(function() {
// 将Offer发送到监控端
})
.catch(function(error) {
console.log('创建Offer失败:', error);
});
}
// 接收监控端发送的Answer
var receiveAnswer = function(answer) {
peerConnection.setRemoteDescription(new RTCSessionDescription(answer));
}
// 监听监控端发送的WebSocket消息
var ws = new WebSocket('ws://localhost:8080');
ws.onmessage = function(event) {
var message = JSON.parse(event.data);
if (message.type === 'offer') {
peerConnection.setRemoteDescription(new RTCSessionDescription(message.offer))
.then(function() {
return peerConnection.createAnswer();
})
.then(function(answer) {
return peerConnection.setLocalDescription(answer);
})
.then(function() {
// 将Answer发送回监控端
})
.catch(function(error) {
console.log('创建Answer失败:', error);
});
} else if (message.type === 'answer') {
receiveAnswer(message.answer);
}
}
</script>
</body>
</html>
```
需要注意的是,以上代码示例中涉及到的一些细节,如WebSocket的实现和信令服务器的搭建等,需要根据具体情况进行实现。此外,WebRTC技术在不同浏览器中的实现也存在差异,需要进行兼容性处理。
