We have the ability to see who is calling us on our phones before we commit to answering and as a highly antisocial person I believe its only fair that we can apply the same tech to our front doors, the Wire-Free 720p Smart Video Doorbell from Swann does just that and even allows you to ignore potential visitors from anywhere in the world. One of the immediate features we were happy to notice was that it can be mounted in a completely wire-free configuration, this makes installation and location an absolute breeze, however this is also where we came across

The Circle 2 from Logitech is a versatile home security camera that can be used in a wired or wireless configuration, inside or outside the home.The super easy-to-install camera features a 180° wide-angle lens that records in 1080p HD and is Wi-Fi connected to allow you to store your footage in your own private cloud. The Circle 2 is beautifully made, using premium materials, looks attractive, and you can choose to power it from the mains or via the rechargeable built-in battery which gives you total freedom when it comes to installation location.
