Least expensive & long term iPad option?
I have several places that I want monitoring capability and I'm thinking that the best solution is used iPads. Am I thinking correctly that any iPad that runs IOS 10 or newer should be OK? And that memory/cpu shouldn't be a factor?
Likelihood that the iPad app will begin requiring a newer version of IOS and so I should get something that supports a minimum of IOS xx.x ?
I'll likely get something from Gazelle or Backmarket though I'm open to suggestions/warnings :-) All but one can fairly easily be powered so a worn battery isn't a huge concern.
