Don’t bother buying Swann Security stuff, guys. Customer support is as a fatberg in a drain.
@Toolegs I had a good long look around the various options & knew somebody who used one of theirs; it looked like it was 12 years out of date the moment he bought it. Decent video quality in the dark though.
I'm leaning towards individual smart devices working through a hub now, but not sure how to pipe a set of looping camera feeds to a drive.
