Avoid Amazon Blink stuff if you do this. I set some up for someone and they're a total scam. They advertise a local only mode that doesn't require a subscription, but it's crippled and makes the cameras nearly unusable. They disable thumbnails and bulk deletion of video.
Worst of all, they'll stealthily enable a "trial" subscription for 3 months when you set them up in local mode, so they seem ok until they get crippled with demands for a subscription fee.
