To work with the service, the camera must support image recording to a remote FTP server when motion is detected. Most modern cameras can do this, but it’s advisable to verify this in the camera’s documentation or in the list of compatible cameras before buying. You can also use programs that work with the laptop’s camera and can write to FTP, for example, iSpy

Registration is free, minimum data is required, only e-mail is required. Add a new camera to your account, get FTP login and password in its properties to specify it in the camera settings.

Enter the server, login, password in the camera settings, configure motion detection, and saving images to FTP. Make sure the camera detects motion and uploads pictures. If necessary, set up the time during pictures will be saved.
Download the Android-app and enable "Enable notification" in the camera settings to receive event notifications.
