Body Camera to Record Myself Being Attacked While Voting

I'm probably going to have to vote in person instead of by mail. If I'm threatened or attacked by members of the Proud Boys or similar groups, I want it recorded.

So I'm looking for recommendations for a body camera that will record audio and video, and not just store it in the device, but also stream it in real time (or as quickly as possible anyway) to a remote location. If the camera is confiscated or destroyed I want the video available for me or my survivors.

I'll also take suggestions for an app for my Android phone, although I lean toward a standalone device.
