Alarm. com app is a extremely reliable security app that connects to dozens of control panels, sensors and z wave products. The majority of all companies use Alarm. com except for the two giants, ADT and Vivint. Anything that uses alarmdotcom as it's backbone is a safe bet. If you want what is hip and cool definitely go for Pulse or Vivint which have their own unique app. In my experience, Vivint's is the best at security camera recording with the ability to go back and fetch time points on the footage easily. Most others takes a long time to go back and view footage, re capture it if needed for authorities. Thanks for the coverage on this post, in buying a home security system this control aspect from smart devices is actually what I'm researching first. Then whoever has the best platform is whom I'm going to be using. You should also consider whether the external doors themselves are strong enough to withstand attack.
