Smart home systems

Hi,

With so many forums and blogs discussing on smart home systems,I am trying to find out which is the best smart security camera which can give me a 180 degree view of my porch and also capture HD Video and i can control the system through my smartphone.Amazon.com and Cannykart.com have some good collection of these security cameras.can someone suggest which one i should go for..I dont want a cheap product which will give away in two months.
