A:Answer You need internet and a router for these. You can use a baby monitor as a security cam without internet, but it won't send it to your phone. I do use a baby monitor to keep an eye on my car at night. The camera just looks out the window.
I recently became aware of the security cam phenomena, after our place was broken into. I now have a number of the blink minis, and they are a total game changer. I can be anywhere; pull out my phone, and look at the front yard, front door, driveway, back door, etc. It's crazy how well it works. My phone will "ping", and i'll look at the blink app, and there is the neighbor's dog walking across the yard! It's worth it to get internet and wifi just for these.
