Also, it's not that good, especially if you watch near the end where you can see the laptop screen, the targetted point doesn't track the guy very precisley, even when he has a large white square, = high contrast target, against a staionary background. a camo'd crawler might make it.
It only tracks one target, 2 people could rush it.
Since the camera doesn't move the arc of fire is limited.
Since it's range is the same as the yours, just hose it down, one ball to the camera and it's defeated
, even splatter would probably degrade it's effectiveness pretty fast.
For current use at a commercial field a human would have to have their finger on the trigger, they could be at a remote location though. even off field.
I think it would be fun to see, I'd love to try and assault a base protected by a few of these.
