Download Aspizo-Traffic-Analyzer-Setup-3.4.25.exe from the Download page and run the installer. Open the Desktop shortcut — the app UI opens immediately; first-run engine setup runs in the background (may take several minutes online). No ZIP extract, no START-ASPIZO.bat, no CMD windows for clients.

Enter Survey ID, survey date, and lane direction labels (e.g. Left/Right or Up/Down). Set buffer seconds if your DVR clock differs from actual survey start time.

Paste a local DVR video folder path, copy videos into the app inbox, or import from a Google Drive share link. Supports Uni+ DVR filenames like Uni+ DVR_ch4_main_20241229150000_20241229160000.mp4. Formats: MP4, AVI, MKV, MOV, ASF, DAV.

Choose speed mode: Fast, Balanced, or Accurate. Draw or auto-place the count line on video. Enable dual-lane mode for bidirectional surveys. Use Flip Direction if vehicle flow appears inverted.

After processing (or stopping mid-run), export CSV with all detected vehicles. Fields include Date, Time, Lane, Direction, Vehicle Class, Speed (km/h), Axles, and Spacing (m). Compatible with Aspizo workflow.

App won't start? Re-run Setup as Administrator and allow first-run dependency install. 0 detections at night? Try day footage first or adjust count line placement. Blank Excel? Ensure CSV opened with UTF-8 encoding.
