Proof of Play

Proof of play (PoP) is an automated record confirming that a specific ad was displayed on a specific screen at a specific time. It is the standard delivery verification in DOOH.

CS Play generates proof of play from two independent sources:

Ad play log

Every ad play is recorded by the player application and reported to the server with a timestamp, screen, frame, campaign and ad. This log is the basis of Ad Play Statistics and statistics exports.

Photo captures

When a screen is equipped with an IP camera (CamGrabber), the system photographs the physical screen during ad playback — providing visual confirmation that the content appeared on the real installation. See Photo Captures.

Together, the ad play log and the photo captures form a complete proof-of-play package for client reporting and compliance.

Ad Play Log

The ad play log is always available — no additional hardware required. Each entry records:

  • Date and time of playback

  • Campaign and advertisement

  • Duration

  • Screen and frame

  • OTS (audience contacts, if an audience sensor is installed)

Access the full log on the Ad Play Statistics page. Export it as CSV, XLSX, or a per-day pivot table via Exporting Statistics.

Photo Evidence

Photo captures add visual proof on top of the ad play log. A camera icon on the Ad Play Statistics page marks ad plays that have photographic evidence attached.

Which ad plays get photographed depends on the CamGrabber photo-report schedule and the per-campaign "Photo report of each ad play" option — see CamGrabber Photo Reports.

Statistics CSV and XLSX exports include a Shot Paths column with photo URLs for each ad play — in XLSX the values are clickable hyperlinks.

Photo URLs in exports are time-limited. For a permanent copy, download photos as a ZIP archive from the Photo Captures gallery.

Sharing Proof of Play with Clients

  • Public statistics link — generate a shareable link on the campaign’s Statistics tab. The client sees ad play counts, a per-day chart, and campaign details without needing a CS Play account. See Sharing Statistics by Public Link.

  • Export files — send CSV/XLSX exports with ad play records and photo URLs.

  • Photo archive — download a ZIP of photo captures filtered by campaign and date range from the Photo Captures gallery.
