Aside from that, the Mevo's selling point is its smart, on-the-fly editing. The 4K cam automatically detects objects (such as faces) and lets you switch between virtual camera angles either on its own or manually, through the mobile app. If everything goes smoothly, it'll look like you have an elaborate multi-camera setup even when you're the only person in the room. The big catch is simply the battery life: you're limited to an hour of recording unless you get an add-on that brings another 10 hours.

Livestream's camera ships in July for a hefty $399, although you can save $100 if you pre-order it now. That's expensive if you're just looking to document your personal adventures (you're probably better off using only your phone). Mevo is more for video bloggers, businesses and anyone else that wants to produce professional-looking live video without a studio's worth of equipment.
