Are there any options to automatically export video after a certain amount of time? We are looking to save all footage for archiving/historical purposes.
I don't believe there is. What type of retention are you trying to achieve? If you need extremely long retention then Meraki cameras may not be the best bet at this point. But using the "Enable motion-based retention? Deletes footage older than 3 days in which no motion was detected." Adds quite a bit more duration to the recordings than you'd normally get.
Nope, you can't do this short of hiring an FTE to sit there and export footage, one hour a time, for days on end.
If this is a hard requirement for you then you're really looking at the wrong product. This isn't a use case that the MV's are designed for.
This is exactly what I wanted to do with Meraki cameras. In my case I would like grab just one picture per day and to send it to some external storage or CLOUD space. A customer wants to send captured a "building proces" on the construction yard.
