Talk to me about security cameras. What's a decent option that includes viewing in app over the internet?

Nest cameras look neat. Netgear has the "Arlo" line, with several options. Those two lines seem to be the best regarded. I'm looking for a couple outdoor and maybe one indoor camera. Being able to remotely (via phone or web) see what's going on (with alerts) would be nice. Recording for at least a handful of days would be nice. And good enough image quality (minimum 720p) so that things seen on screen are distinguishable as to what they are.

I know there are tons of other considerations for this sort of tech, but I'm curious what those of you who know about these things are using for your security systems?

Thanks.
