With this thing, why even bother carrying it around? This could be the beginning of the next generation of hunting technology.
This thing clearly doesn't need to be carried around by a person. They should just mount it on some kind of silent running RC ATV and send it out to the desired location. When something pops up on infrared, have it notify the hunter via SMS and they can call up the video feed on their smart phone and decide to take the shot or not. Hell, with the image recognition it seems to have, it could probably be tweaked to identify game and only send the message if it's the correct species.
With proper software, you could hunt from the convenience of your cubicle. Wouldn't even need to take time off work.
What a world we live in.
