$9.99 a month or $99 a year for a rolling 7 days of video. I guess most of that is a still, unattended image. Amazon cloud storage is cheap. It seems very expensive to me.
For example. My flatmate has a child. His ex-partner is prone to make stories in her head and go to the police with that. I'd be keen to host the kid until the father comes back from work, but I'm afraid of the ex-partner's accusations. I'm looking for a cloud storage service to store those hours for a few years, not to serve as legal proof, but to reassure the ex- that nothing weird happened. With Dropcam, that would cost me a few thousands dollars of storage per year, or am I mistaken?
