Set the file naming convention to overwrite the same file, such as webcam.jpg .

// download single snapshot by id or dataURL directly function downloadSnapshotById(snapshotId) const snap = snapshotsArray.find(s => s.id === snapshotId); if (!snap) return; const link = document.createElement('a'); const dateStr = new Date(snap.timestamp).toISOString().slice(0,19).replace(/:/g, '-'); link.download = `evocam_$dateStr.png`; link.href = snap.dataURL; link.click();
You can create a truly branded experience for your viewers by editing the video overlay in EvoCam's WYSIWYG canvas. You can add and customize:
.cam-btn.primary background: linear-gradient(105deg, #2563eb, #1d4ed8); border: none; color: white; box-shadow: 0 8px 18px -8px #1e3a8a; Best Practices and Optimizations // download single snapshot
// tooltip for better interaction : small const styleInfo = document.createElement('style'); styleInfo.textContent = `.cam-btn:disabled opacity: 0.5; cursor: not-allowed; filter: grayscale(0.1); `; document.head.appendChild(styleInfo); </script> </body> </html>
If your website receives high traffic, hundreds of concurrent users downloading a 200KB image every 2 seconds will rapidly drain server bandwidth.

Use code with caution.
To make this functional, you must link the video source to the live stream URL generated by EvoCam (often an RTSP or HLS link). For modern mobile support, the HLS ( .m3u8 ) link is generally preferred. 3. JavaScript and MediaDevices API
