Analyze Live Video Streams

// Capture frame from video
const canvas = document.createElement('canvas');
canvas.width = video.videoWidth;
canvas.height = video.videoHeight;

const ctx = canvas.getContext('2d');
ctx.drawImage(video, 0, 0);

const frame = canvas.toDataURL('image/jpeg');

// Send to Moondream API
const response = await fetch(apiUrl + '/query', {
  method: 'POST',
  headers: {
    'X-Moondream-Auth': apiKey
  },
  body: JSON.stringify({
    image_url: frame,
    question: 'Is there a delivery person at the door?'
  })
});

// Process the answer
const data = await response.json();

if (data.answer.includes('yes')) {
  // Trigger alert
  sendAlert('Delivery person detected');

  // Log event
  logEvent({
    timestamp: Date.now(),
    detection: data.answer
  });
