Is that an infrared camera mounted to the top of the unit? If so, it would seem like it's detecting the location with infrared and pointing some energy at it. What if the device is, say, in a pocket? All the pics also seem to show the charging sleeves with their backs pointed at the unit. If they can't work from other directions, that's a huge red flag.
