Budget video surveillance and cloud drive storage, how to organize?

Question

CCTV

Good afternoon, the task is to organize video surveillance in the house,
Requirements:
1. storage of video up to 5-7 days in the cloud,
2. storage of alerts, for example, from a motion detector.
3. Notification of detection in a telegram chat
There will be about 5 cameras, rather ip with IR illumination, as a local server that will upload to the cloud will be a nettop or a laptop with a processor below core i3.
The first point is not important if 2 and 3 work well.
4. Your option
I can't store everything locally because there is only one house on the site and in case of theft they can take away the laptop from the video. (There is no place to hide the dvr).
By cloud I mean google, ya, mail drives.

Usually cameras are able to write to FTP, and you need to start from this.

Use a cloud service for video surveillance. For example, https://ru.ivideon.com
Notifications when a motion sensor is triggered in the android, ios application. To connect to the cloud, you need to find out the rtsp link to the stream. Usually in the documentation or google. There are no more special rakes.
