Review on Call with motion sensor Ring Video Doorbell 2 electronic wireless by Nguyn Thng Qun  (Chu ᠌

Has pros: High-quality intercom with the possibility of video surveillance. The wide-angle camera captures a large area. It is possible to record video (along with audio) on the detector on the cloud service and view the video in real time either through the website or through the mobile application. Function of the remote answer to a call in a door. Low price for an annual subscription to the cloud service: about 3,500. Its cons: When working from the battery, the charge lasts for two to three days. Charging the battery is long, more than four hours. You can connect a constant power supply, but I did not find ready-made adapters in 2022 stores. I had to assemble myself. Payment for a subscription to a cloud service works only with cards of foreign banks. The price on the 2022 market is quite high: Chinese counterparts are two times cheaper.
