A July 8, 2022, Today article noted that the video was captured on a SimpliSafe security camera.
The Today article also quoted from SimpliSafe:
"Customer video and audio cannot be accessed without permission by anyone besides the owner, so we were just as shocked to see the video online after the customer shared it," Scott Braun, chief growth officer for SimpliSafe, told TODAY Parents in a written statement. "As a company that’s in the business of protection, we do not make light of events that would put our customers’ safety at risk, whether those incidents are within our control or not."
As to how the video ended up on the internet, the Today article reported:
After some digging, the family figured out how the video got online. Worried that any nearby vehicles may have been damaged, the homeowners sent video of the incident to the vehicles' owners, in case they had to file an insurance report. One of those owners sent the video to their brother, who they say then posted it on Reddit.
"The original poster of the video did actually reach out to us and sincerely apologized," the homeowner explained. "He never imagined that things would go this far. He actually took the video off of his page on Reddit, but by that time another gentleman on Twitter had posted it, and it just really blew up."
Please see above link supporting my prior statement.
I did not say ‘Ring did it’, however it seems a likely escape vector for such videos as the one in question.
