Surveillance in most cases will not save the play of a counter unless the house took a large beating. With the days of old, we had video tape and a ton of VCRs which made taking video tapes out of rotation and shelving them for counters costly and inaffective. I've worked stores that had a 25K pull and others were 50K and above.
Today many casinos are digital. This makes the saving of video and images easier, but they wont bother for a counter (especially a low end counter like were talking abouut here) with each return trip starts a new evaluation.
If surveillance needs to, they can obatin your name or players card information and pull up the dates you played, length of play,wager, table, B/I and cash out, ect.
