It would be a rather simple device to make at home. But that price is really good for a manufactured item. I could probably make it for $20 as a DIY but $69 isn't bad.

when no one even knows what kind of drones will be used or what they look like?
There are dozens of flying gizmos that could be defined as a drone.

We aren't going to have armed weaponry flying over us every day and blowing up neighborhoods and buildings all over the country.

This drone panic is idiocy and this guy is simply a scammer.

But that one is more for following people than for using electronic surveillance to check on what is occurring in any particular home. Theoretically there must be some degree of proximity for this to occur, albeit not noticeable proximity. I imagine that WIFI is as vulnerable to spying by drones as is the visible spectrum via cameras. I posted an article here a bit back regarding DHS having placed spy tech in domestic drones despite having claimed not doing so. It will pay to bone up if you are an activist, although of course in so doing, you will present "negative space" equally as "visible".

Fuck the security state and its neocon/plutonomy/Bush family masters.

way to dismantle our right to privacy. It's crazy that it has come down to this but the powers-that-be don't give a shit about our rights.

to have a raspberry pi and a microphone in it. It would probably have to be at least 4 inches long. And if you are going to mount it outside it would have to be weatherproofed, I'm thinking this is vapor.

That I know I is there how exactly do I then "protect" my home from surveillance?
