Webcam Motion Sensor is a free opensource Windows application for detecting and capturing motion via webcamera. Captured snapshots can be uploaded to Google Drive.
Webcam Motion Sensor doesn't capture video, it's capture snapshots and can be used with free Google Drive subscription (15Gb limit).
It very simple to use. Just unpack ZIP - archive and run WebcamMotion.exe. Configure folder for snapshots.
You can upload your captured copies to Google Drive.
Set checked "Upload copies to google drive" and choose directory for copies. After pressing "OK" you will be asked to approve permissions to use Google Drive at your Google Account. Now, all of snapshots will be uploaded to Google Drive. Copies will be instantly deleted after uploading.
Application can send notifications to Telegram when motion detected. It is consist of snapshot and alarm message.
Set checked "Send motion detection notifications to Telegram". Enter your phone number and click "Send code". You will receive code in Telegram Application. Enter this code and click "Login". If everything fine, then session status will be changed to "Active".
Messages will be sent to self chat. Messages in self chat are coming already readed and without sound notification. So, you need to look new messages in Telegram sometimes. Yes, it's really not cool, but I have no idea how to do it better without using Telegram Bots. If you have better ideas, you can contact me.
