An ideally designed SD event detection system operating flawlessy would be effectively equivalent to SD continuous recording because motion within any single minute would be detected and recorded.
If motion visible but too subtle to register occurred during any minute nothing would be recorded during that minute and context it may have provided for the prior or succeeding minutes will be absent.
If continuous recording were made the only option the problem for the devs would be to make detection as close to ideal as possible and to design an interface whereby the user responding to a detection alert notification would be taken directly to the time point on the SD card where the detection occurred.
Cloud clips would be adjunct to the operation of an independently operating local system.
This requires a reliable consistent local storage system which SD as far as I can tell is not and will not be.
Which may be why they introduced that network local storage device thingy.
Now if all this deductive/inductive foofaraw is valid I would hope that devs would be compassionate enough to tell their friends the motivated customer not to break a sweat troubleshooting a flawed system that is on the brink of being replaced.
If they can’t do this because that would mean some people would stop buying the current product until the improved product debutes then ok I get it game-set-match.
But I’m guessing they will not abandon the SD card option because hell a lot of people are dedicated to it in a big way and may not want their recently purchased gear to be thought of and treated as entry level or legacy.
Or some such thing galumph.
