Yes, sure it is possible. While viewing the video stream, tap the ‘Camera’ icon to reveal the in-app camera functions: capture image, record video, and gallery.
Tap on ‘Capture’ to take a snapshot or on ‘Record’ icon to start manual recording.
Please note that manually recorded videos are not saved onto the Cloud. Instead, they are saved onto your mobile device, and you can access them from the tab ‘Gallery’ within the app.
The maximum length of time you can manually record video to your smart device is defined by the amount of memory available on that smart device.
