USA racing pics

[Heisenberg]

Similar to the AU thread of the same name.

Used to have a huge (but not scalable) edge on the US in-play horse racing markets but having looked into it again recently since the demise of the AU stuff, it's obvious that the market is a whole lot more intelligent these days.

Someone is getting fast pics, now it's not tracksiders because most of the tracks aren't allowing patrons on course (and there's also the ban on Betfair over there, easily circumvented I know but still an obstacle.

Done a lot of digging and while there are dozens of sites offering streaming (ADW's and subscription services, as well as BFLV), they are all sourced from the same provider and latency is essentially identical. I don't expect anyone to give away their golden goose but does anyone have any clue on where these pics are coming from? Thanks!
