Feature suggestion just to add capability for up to 256GB or so for storage space separate from paid subcription for cloud storage. Just give people the choice, would be nice.
Yes please add memory card function. Lost internet connection for period of time and no way of knowing what occurred.
Where I would want to put the Ring doorbell is in a location with very slow internet and having it upload constantly would bog down the internet and not productive for anyone using the internet. Having a SD card to save the video would give this the push for me to purchase it rather then going to look at another device that has this feature.
Ring please respond to comments about feature requests, so we know your acknowledging customer desires.
