If you are looking for a smartphone based, self-monitored home security system in 2017, I recommend either iSmartAlarm or Abode. If you prefer a camera based system, I recommend Arlo Pro backed by SmartThings. This video reviews the basics of all three systems including apps, remote access, security cameras, home automation, as well as pros and cons.

I purchased the iSmart camera and everything SmartThings on my own, but the iSmartAlarm system, Abode system, and Arlo cameras were given to me for testing. I was NOT paid to make this video. All opinions are my own. If you choose to buy Arlo Pro or iSmart using the links above, I will receive a small commission which I will use to keep this channel up and running.
