The Ring Video Doorbell Pro costs $249 (£195/AU$325, converted).
You can program the Ring Pro to send you alerts whenever someone rings the doorbell or when it simply detects motion.
The Video Doorbell Pro measures just 1.85 inches wide -- significantly smaller than many models sold today.
This connected buzzer has a detachable face plate and your purchase includes all four interchangeable color finishes: satin nickel, venetian (pictured), satin black and pearl white.
This buzzer also works with IFTTT, Wink and select standalone devices, like Belkin WeMo products and Kevo smart locks.
