A member mentioned that he upgraded his SD card used in a Samsung camera from their 'Ultra' to 'Extreme Plus' line. While those terms sound like marketing mumbo jumbo they do reflect one major specification difference.
An 'Ultra' card supports Class 10 speed (30 MB/s read) while an 'Extreme Plus' line supports UHS-1 (80 MB/s read). See the SanDisk series overview / comparison page.
By comparison, "Axis recommends using SD cards of acknowledged good quality with speed class 4 or higher." That's far far lower than both a Class 10 or an UHS-1 card.
On the other hand, lots of IPVM members are reporting problems with Axis edge storage recording, presumably with non UHS cards.
So this begs the question - do surveillance applications need the more 'powerful' UHS (Ultra High Speed) cards?
And, if so, do IP cameras even support that?
Any ideas? Experiences?
