Not sure they can be done that way.
The bulk of the update could probably occur in this fashion but each cam would likely need its own seperate hit in order to set its pq pair. Any card would then have to match boxkey and pq pair.
I would assume that Kudelski would only produce "hits" for cams that are registered as in use by a provider that has gone to N2 and these would only be transmitted on that providers channels.
