A team of persons enter the Target's home or motel room and perform medical procedures and implantations while they are asleep. The government wants your personal frequencies so they can deliver torture through blasts of frequencies using ordinary communications platforms with WiFi frequencies of 2.4 GHz or 5.8-8 GHz. They use technology that can put thoughts and voices in your head, read your emotions or induce emotions and cause havoc with your hearing, sight, sleep and brainwaves. 
TI SECURITY
If a surreptitious entry is in order, there's not much you can do to prevent it.  Therefore, your security should be geared more towards detection, and evidence of physical tampering rather than that of entry prevention.  
you should setup your security in a fashion that will show physical evidence if any tampering has occurred.
I believe that there are four primary reasons for the surreptitious agent entries into a target's home:

    Survey and observe what's going on in your home;

    Surveillance setup;

    Psych-ops effects;  and

    Food, water & chemical tampering.
High-end Locks:  I'd recommend a keyed lock and a padlock for your door's exterior. 
Concealed Cameras:  Use multiple concealed or hidden cameras throughout your domicile at the earliest hint that you are being surveiled.  
Use invisible fluorescent dust on steps or handles. Loosely place a low-lying "hair wire" or micro-fiber across a walkway or doorway 
    Single Entryway:  Only one door should be accessible with a key from the home exterior and this door should be very visible to neighbors and the public. This door should be brightly lighted, consistently each evening (preferably with battery backup) so that it will potentially pique interest from neighbors in the event that the light is tampered with or turned off at night.  Place some type of eye-catching item (eg., a really small, non-annoying strobe light) in the vicinity of this door when you are away from home. This will continually attract attention and the occasional glance from neighboring and passing eyes.
 Posting:  Post a discreet and classy Reward Sign somewhere on your property "for the capture and prosecution of anyone found tampering with or attempting to burglarize your property." This posting will sit in the back memory of neighbors and those who have observed it and it will subconsciously draw more of their attention and glances to this area on a daily basis.
Trash:  Don't discard your trash within a contained bag ; empty your trash in free-form, allowing it to mix in with other refuse.
If you live in a rural location you will need more strategic deterrents.  Rural locations are actually more vulnerable because once you are away from the property, the criminals can move into action and spend as much time as is necessary to attack your property without the fear of being spotted.

[ Doors ]

Door hinges should not be exposed to the exterior. Doors should be windowless. The strongest door and lock in the world is only as secure as the frame and jam that envelop it. I recommend the use of both a high-end keyed lock and a high-end padlock for your doors exterior along with a interior-side-only-keyed-deadbolt. Knowledge on how to defeat these high-end locks eventually evolves, so the same models that are esteemed at the time of this writing may be irrelevant tomorrow
Wireless systems may seem hi-tech and cool, but they can be defeated via frequency jammers. Hard-wired units with a back-up uninterrupted power supply is preferable. When using keypads or combinations use confusing dummy sequences while only truly depressing the actual combination code keys. Heat signatures can be read on the touched keys with IR, and the unique frequencies of the individual keys can be sniffed-out with remote RF scanners.  ArgenMesh shielding could be explored in these situations. Infrared and wireless sensors can be jammed. Laser, acoustic, compression or fiber-optic sensors may be a better alternative.
[ Windows ]
Keep blinds drawn when away from home. Install a screw or stick into window jams to prevent the window from being slid open, even if the glass is broken.  Use security film, laminated or reinforced glass.
Hard-wired lighting, out of reach, is recommended in obscured areas of the home's perimeter.
[ Cameras ] 
Hard-wired cameras should be placed at exterior corner locations to allow for video capture of all angles.  (The wires of the cameras should be protected with flexible conduit or pipe which can be found at a home improvement store.)  They should capture areas of main entryways as well as obscured locations that neighbors can't see.  Infrared LED beam cameras reduce the need for additional exterior night-lighting (LED cameras cannot be used from behind a window or protective covering, due to reflection glare). Wireless cameras are susceptible to signal jammers. Connect cameras to a DVR or hard-wired computer that can either store the footage or relay the footage over the internet or to a smart phone. Utilize dummy cameras along with real cameras.  Use concealed or hidden cameras.  Utilize a wild game, hunter or nanny motion camera. Insure that the recording equipment is concealed or placed within a locked space that would show evidence if tampered with.
[ Automobile ]
Car alarms may only be a small annoyance to someone with skills.  One of those strobe light & siren combo units that locks onto a steering wheel may be more effective due to its novelty.  Use your manual key instead of remote key when possible to lower the risk of an offender cloning your remote signal key.  Unless you know and trust an automotive professional who will help you out, you should not even waste your time searching for GPS tracking units installed on your car.  They are really small now and their signals may be pulsed and difficult to detect or static until movement is detected. Some GPS units stay in sleep-mode until they are "called" by the offender to wake up and transmit coordinates.  There are some reasonably priced dash or mirror cameras available that may be useful in cataloging incidents involving offenders out on the street.  Watch for tampering with your tires or wheel bolts.  Watch for dripping fluid from under the vehicle.  
[ Information Technology ]
​Computers:  
Use an Ethernet land-line when possible and keep it disconnected as much as possible (air gapping).  Use open-source software applications.  
Use keyboard and hard-drive encryption software.  Use a robust and ubiquitous anti-virus program.  Use a robust Firewall!  
Utilize virtual operating systems when performing risky or private tasks (e.g,TAILS). Use proxy chaining or at least just a simple proxy.  Use encryption software (TrueCrypt).  Use encrypted email services.  
remove your phone's battery.  Place a small piece of electrical tape over front facing cameras.
Be aware that your device (computer or phone) can be tapped into remotely by RF sniffers.  The keys you press and the images on your screen all emit unique frequencies that can be scanned remotely and reconfigured into a character or image on the offenders system. 
Using something like screening metal Mesh/cloth may attenuate the signals your device emits when it is draped over your device.
    Pepper Spray - Non-lethal pepper spray in a compact canister can be used by anyone and can be very effective against man or beast.  Spend a little extra money for a quality multi-shot product.
    Telescopic Collapsible Baton - Non-lethal means of physically defending yourself around your property.  This is recommended over a  baseball bat, which can be extremely lethal;
    Blade - Lethal means to protect yourself in the event you can not access firearms    Firearm - Lethal means of self defense.  A quality revolver and shotgun make good home defense firearms.  When away from home, a quality pistol is the best option.
If you have a steering wheel lock in your car, it can double as a blunt-force club.  Lastly, there is one weapon you can carry with you everywhere --- your belt and buckle.  A heavy, solid buckle clasp or a loop buckle that could accept something hooked or clasped onto it (for example, a heavy key chain or ring of keys)
