2) This is not something we plan on offering. Today the Meraki MV infrastructure is managing way in excess of a petabyte of data and a billion individual video files. Taking the data off the camera and out of our infrastructure looses the associated metadata and the ability to perform all the cool things we offer such as motion search, heat maps, and motion based retention.
We don't want to offload the problem of dealing with large amounts of video to customers when we have already solved that management aspect. We know some customers want to store longer or have offsite backup, and we will investigate how to offer this in the future.
Regarding camera destruction or theft, no system offers perfect protection from a disaster. I have personally spoken to customers whos hard disks died, RAID arrays became corrupted, or even one who had their NVR stolen. In each instances, all video was lost. With MV, yes you may loose a camera, but the likelihood of catastrophic data loss is significantly lower. If camera theft and destruction is of concern, use the MV71. It is extremely rugged and I can personally attest to beating one with baseball bats, crowbars, and hammers. It is a tough little beasty.
3) This comes up now and again as an ask. My main question back is "How would you power it?"
