Export guide — Hikvision
Menus vary slightly by model, but every Hikvision recorder has an export path within a click or two of these steps. You'll need a USB stick (32 GB or larger). When you're done, head back to the upload steps.
Use the USB port on the front or back of the DVR/NVR box (not the TV/monitor).
Right-click with the recorder's mouse → Menu → Video Export (on some models: Export, or Playback → select clips). Log in if asked — it's the same PIN you use to view playback.
Tick the camera that sees your main sales floor. Set the date, and the start/end time to your opening hours (e.g. 09:00–19:00). If a Stream type option appears, pick Sub-stream — smaller file, same analysis.
Choose MP4 as the file type if offered, select your USB stick as the destination, and hit Export. The recorder shows a progress bar — a full day can take a while; you can leave it running.
Using a computer instead? Install iVMS-4200 (Hikvision's free desktop app), add your recorder, then Remote Playback → pick camera & time → Download. Files land as MP4 on your computer — send those.
