It looks like . . .
. . . a number of microwireless pinhole cameras that I have, but I do not think for a minute that it is any kind of government conspiracy - rather, I believe that the individual making the presentation is the creator of the "conspiracy". It would take a professional evaluation of the unit to determine if it was real. Is it wired into the "box" for power (8 to 9 volts required), and to whom is it transmitting? The little pinhole cameras typically have an non-obstacled range of no more than a thousand feet. Start throwing walls and windows in front of them, and that transmit range goes way down. Are there black Suburbans outside his house, or black helicopters above his domicile?
