Sounds like its alot less useful in detecting if your home than the heat detecting cameras they have been using for years. In terms of privacy
invasion Id say this is a pretty piss weak tool and nothing to worry about.
I can see more potentially life saving applications than privacy invading ones
Except that thermal imagers cannot see into your home but this technology can.
To stop this type of scanning through walls, you need to be aware of
the TYPE of Radio Frequencies (or other bands!) used for scanning
through items. One key term is "FREQUENCY" or the number of
Cycles Per Second (also known as Hertz) used to send a signal
into or through an item or wall.
The higher the frequency, the shorter the distance (i.e. range)
per unit of power (i.e. expressed in Watts) that the wave can
travel on a coherent basis without being scattered, attenuated,
refracted, diffracted and reflected by in-between objects
such as buildings or walls or by the atmosphere.
To Stop MOST Radar, RF and Wireless through-the-wall detection
systems, you use multi-layer sheets of mu-Metal, Tungsten, Copper
and other types of sheeting that are RATED to STOP RF waves from
800 MHZ to 1900 MHZ (i.e. many cell phones), 2 to 5 GHZ (wireless 802.xx)
and the 8, 9, 15 GHZ, 30 GHZ, 60 Gigahertz bands (Radar) and then up to
1 Terahertz+ systems they use to scan for items within and through
walls, ground, water and other objects.
See link on Radio Frequency bands:
If you make sure your walls and doors are properly covered with those
layered materials, with any seams in doorways, window coverings and
other openings that are covered fully and properly to prevent leakage,
you are in effect creating a Faraday Cage!
See link on Faraday Cage:
A Faraday will protect against ANY type of Radio Frequency scanning
OTHER than acoustic energy scanning (i.e. 0 to 100,000 Hz or 100 KiloHertz).
But you can even protect yourself against soundwave imaging by including
acoustic (sound) absorption panels into your Faraday Cage-enabled
home designs! It would make your home interior a heck of a lot
quieter from outside noise as an added benefit!
If you're TOTALLY paranoid about being scanned through the walls,
you could ALSO protect yourself against X-Ray and Gamma Ray band
scanning techniques by adding THICK (2 millimetres up to 100 millimetres)
Lead, Tungsten or even GOLD multi-layer sheeting to your Faraday Cage
home protection system. If you have PROPERLY fixed all seams
(i.e. doorways, window coverings, etc) you would also be
protected against EMP (Electro Magnetic Pulse) effects!
If you're of the DIY (Do It Yourself) type you can use 1/16th-of-an-inch
single-sheet panel aluminum and a 1/16-of-an-inch sheet of cheap steel
that are glued to and separated by a sheet of 1/4 Inch plywood that is
FULLY PAINTED with RF Protection paint. Then paint the entire
sandwiched sheet with 3 coats of polyurethane truck-bed liner
paint for its sound insulation and weather proofing qualities:

Spray-in Truck Bed Liner Paint: (polyurethane is best!) as final covering:
The TWIN combination of aluminum and steel sheeting
on RF painted plywood form a TYPE of RF shielding
SIMILAR to mu-Metal but is a heck of a lot cheaper!
See Mu-Metal Link:
Cover your entire house with 4x8 foot sheets
of such DIY RF sheeting and MAKE SURE TO COVER
ALL SEAMS in between each sheet with RF Painted
metal strips and ENSURE YOU SHIELD ALL your
windows with anti-RF screens and you are
SET against almost all types of
This type of sheeting can be MADE for less than
$100 to $125 per 4x8 foot sheet if you can buy the
RF shielding Paint, 1/16" thick aluminum and steel
sheeting at bulk prices 25 sheets minimum to get
The spray-in-truck liner cover paint goes
for between about $60 to $135 for a 1-gallon can
which can cover one to two full sheets.
If you're more cost conscious use polyurethane
exterior paint at about $30 a can at
Lowes hardware store!
Hope this helps!
