Are there safer ways to preserve video evidence in dangerous situations?

Do you know of any app or tool for safer video recording in a dangerous situation?

I mean something more than just recording a normal video on your phone. If someone attacks you, threatens you, or you are in a situation you need to document, a regular phone video can be stopped, the phone can be taken, the battery can die, or the file can be deleted afterwards.

I’m wondering if there is an app that starts uploading the video immediately while recording, or works like a live stream to the cloud, so the footage does not only exist on the device.

Ideally, it would also be possible for a family member or another chosen person to access the stream or download the video later if something happens. Another important part would be that the person recording could not instantly delete the footage under pressure, at least not without some delay or external confirmation.

Does anything like this exist? Or do people use some other setup for this kind of situation?
