Vivints currently product is not a smart home solution; it is a security system with a simple camera and an automated door lock. If you are looking for a smart home solution I would suggest you look else where.
There are cheaper and more versatile systems on the market.
Even Vivint's older products are more versatile than their current product. Maybe in a few years when they get their act together Vivint will have a good product but for now I would suggest you go elsewhere.
