Ring Video Doorbell Pro is a doorbell that also acts as a surveillance camera. Thanks to a wide-angle lens with a 160-degree angle, it covers the territory not only at the door, but also in front of the house. A zoning function is provided – with its help, the owner of the house can highlight certain fate and, if movement is fixed on them, the corresponding message will immediately appear in the company’s application on the smartphone. To do this, Ring Video Doorbell Pro connects via Wi-Fi to your home network. Infrared LEDs allow you to shoot even in the dark. All captured videos in Full HD format are stored on a cloud service, the use of which is paid separately every month ($ 3). In addition, the device is equipped with a microphone and speaker, which allows you to communicate with the visitor without opening the door. The cost of Ring Video Doorbell Pro is $ 250.
