This Wi-Fi-enabled doorbell, also known as the smart bell is of great use! This doorbell lets you know who is at the door whether you are at home or not.
Apart from offering peace of mind and relieving curiosity of knowing who arrived at the door, this bell is affordable and easy to use.
Formerly known as Doorbot, the founder Jamie Siminoff valued it at $7 million. The offer was eventually turned down but it attracted a lot of buyers due to its home security capabilities.
Recently Amazon bought this in a business deal for $ 1 billion as it swore by its versatile capabilities. If Amazon trusts the product, we have enough reasons to believe it.
