I didn't bookmark them, unfortunately, but this question has been asked several times on HN that received good discussion. None of them felt outdated to me, really. I chose a wireless camera system, with a local DVR that I can access via PC or mobile. You can, if you choose, feed those cameras into different software programs and have all the motion sensing and advanced config you'd like. That might be more than you want to setup, though, and if that's true, there's some packages that sell DVRs with those same features. My sister, who isn't very tech savvy, has managed to do all kinds of things, like masking parts of the room from setting off motion detection, with the packaged software. Anyhow, I'd start off with the search feature.
