Kevlar Sheets for Your Home Walls
Home security is more important today than ever. You may have even considered Kevlar Sheets for your home or car. They are available and there are some companies who specialize in these things. The military uses them in Humvees and other vehicles. In the Vietnam War the spotter planes and helicopter pilots would put bullet-proof vests on the floor boards since the AK-47 rounds would come up thru the aluminum and kill pilots. Without getting too dramatic you might wish to employ the same strategy in your home. Carbon Kevlar sheeting can be placed in walls in certain safe rooms to protect you and your family. You can put them in the ceiling so when Cinco de Mayo comes around and everyone is firing guns into the air no stray bullets will come thru your roof and kill you while you sleep; like you can sleep anyway with a bunch of drunken, mariachi playing, pinata cracking, loud yelling folks are having an all-night party anyway? Don't laugh you know what I am saying here. If you have a two-story you might wish to put them in the floor boards in kids rooms; perhaps in the walls of the master bedroom. You can purchase these sheets on the Internet; here is one company we found: http://www.geminicomposites.com/products/kevlarsheet.html Another major important thing to have is a good alarm system, one which you can rely on to give you those precious moments you need to get the family into a safe protected room and for you to lock and load and go hunt yourself down some soon to be dead burglars. Think about home safety, alarms, Kevlar and a good weapon to take out the evil do'ers who have invaded your family's domain.

Protect Your Family From Solar Flares
Protect your family from solar flares. Solar flares emit dangerous gamma radiation, which affects everything from gravity waves to the Earth's tectonic system. These solar flares are dangerous to human life. The Gamma Radiation is dangerous to the human bio system. Many severe solar flares can cause cancer and It heats up the atmosphere and can drastically change weather patterns too. We have had some serious solar flares in the last few years, which have affected our lives. Some say that Earthquakes are in part due to the disruption of the natural electromagnetic distribution of the Earth along with causing disruptions in gravity waves.
Emergency Telephone Numbers
Emergency is a situation that poses an instant threat to human life or possessions though this description may be different in some areas. Deliberate bogus reports of an emergency are usually prosecuted as an offense. One should call for help any time there is a danger for life or public order. The emergency telephone number is a special case in the country's telephone number sketch.
Who Abducted the Missing Child?
What is going on with these people who feel they can walk onto your property or in front of your home and abduct your child? If those parents had installed a hidden camera in their home, the police could use the recordings from the camera and have a quick lead to find the child and return them safely. Being prepared for the unthinkable act of your child being abducted by installing hidden cameras is much better than wishing later you had installed cameras!

Katrina: Lessons Learned on the Nature of Man
For many years, novels and films have given us apocalyptic views of how easily mankind could disintegrate into ruthless barbarity once removed from the constraints of law and order, and the comfortable smooth machinery of "civilization". But all that was just fiction, right? Not really. The reality is in the news.
Who Has Keys to Your Castle?
One area of home security that is often overlooked, and one of the most visible, is the common key. Even if you are the owner of a new house, or the first tenant of your apartment, you cannot be sure that no one else has a key to your door.
Fire Safety Tips
Did you know that fire is the third leading cause of accidental deaths in the United States, yet most people ignore it. More than 150 workplace fires occur every day. So many of theses untimely deaths could have been prevented if they only had a plan.
Eavesdropping and Counter-Measures: Technology and Techniques
You need to know how to protect yourself, since your security department or
any consultant may not be truly aware of these threats and therefore not
dependable. Since September 11th, a number of businesses entered the security field with little to no knowledge of the trade itself; only of its profit potential. Even outfits that have been around for some time and well-established have not been able to stay current with the latest innovations.
Realistically, viewing your threat level has to be considered since everyone
should expect some sort of impending privacy issue no matter how small. Thanks
largely to the Internet you can arm yourself with much of the knowledge and
equipment that the so-called experts use. If a respected agent of computer crimes
for the Secret Service in NYC had his T-Mobile Sidekick hacked, who knows what else
happens out there to others in any business.

We'll start acoustic ducting evaluation is the inspection of air ducts, baseboard
heaters, coffee rooms, lounges, bathrooms or any way the architecture of a building
can transfer sound. A simple example is to put your ear to a wall and listen.
Basically anything that requires the use of the naked ear is called an acoustic
bug. Softer surfaces can help muffle sounds but there are more efficient means out
there. So be aware that the way an office site is designed can act as a conduit for
conversations. Also, be aware of any changes can have adverse affects. Simply
playing music can do wonders for masking conversations.
Inspection of telephone equipment and wiring is called line analysis. This is
trickier than it seems since sometimes a possible weakness has an actual purpose to
the telecommunication system. Especially if it requires constant maintenance and
software upgrades.
All instruments should be opened and inspected. Ideally they should be
compared with a known safe phone or device. If you're not sure, just remove that
piece of loose components and wiring and see if the phone still works. The wiring
can be modified in a switch within the handset that essentially turns it into a
microphone. If you bypass this hook switch, you can listen in from anywhere on the
landline. Technical
equipment won't be able to detect this. Time Domain Reflectometry is the sending
of a pulse down a telephone line. If there is some sort of disruption; a wall outlet or
wiretap; a portion of the pulse will be
sent back to the device called a Time Domain Reflectometer (TDR). Then the time
difference between the reflection and the continuous run is measured. This helps in
determining the distance to the anomaly.
These devices can perform all sorts of diagnostics including mapping a wire
network. That can be useful in locating a hidden phone. Hidden phones have several
obvious uses such as making long distance phone calls to being placed in an office
across the street to receive betting requests by bookies; a practice called back
strapping. If you open up the modular jacks where you connect your phone, you'll
usually see four wires. In most cases only two wires are connected; commonly
known as ring and tip. If you see all four connected, be aware that is not usually
consistent for most wiring situations, especially in homes. The other two wires
could be used for a bugging device.
For instance, the microphone you use in a voice recorder can be cut in half.
Connect the mike head to one set of unused wires anywhere on the phone wire.
Then, so long as there are no breaks in the wire, connect the other end to the jack
that connects to your recorder. Now place your recorder to be VOX (voice) activated
and now you have an extremely reliable bug. By the way, this should be manually
inspected for since using a specialized bug detector may see nothing wrong or
inconsistent. A bug such as this that connects to a wire is called a direct tap.
The other general type is called an inductive tap. This is when an instrument is
outside a wire but can still distinguish what's transacting over a wire. They are
harder to detect since they don't draw power from the line such a standard
telephone would. These are referred to as snuffle bugs. A simple probe used in
hunting wire signals has a speaker, which can display sounds. By
accident one day I was working on an apartment intercom system while using a
probe. I could hear conversations throughout the building quite clearly just
through the intercom boxes mounted on walls from the master unit in the
basement.
If you're using wireless headsets or cordless phones, the radio signals can be
intercepted. A cordless phone acts like a radio, but depending on the frequency and
a few other factors, can make interception extremely difficult. With some
manufacturers, you can buy the same model as your neighbors or the office and
have it join their phone system. Double check Caller ID boxes to see if they also
record numbers dialed besides obviously those being received. If you're using VOIP
(Voice Over IP), remember that calls can be recorded in a fashion identical to
intercepting data between two computers.
These packets of data can reassemble an audio file. Obviously electronic
devices possess semiconductor components such as diodes, resistors and such. The
method to hunt for these components is called Non-Linear Junction Detection
(NLJD). The NLJD unit emits a radio signal while listening for the return signal from
an electronic device. This becomes very useful when a bug is embedded in a picture
frame or wall. The eavesdropping device doesn't have to be active for it to be
discovered. If a device is active and transmitting wirelessly (or even on a wire), you
can detect it with a Radio Frequency Spectrum Analyzer. Depending on the detection
device used, you can determine whether voice, data or video is being sent, and
possibly listen to the data. Try to use different size antennas or buy one that
collapses. Different frequencies can be detected more efficiently by using various
sizes. The use of filters with antennas can also help pinpoint devices on specific
frequencies.
Electronics such as computers, FAX machines and especially CRT monitors can
radiate electromagnetic signals or pulses that can be received by other equipment.
This is known TEMPEST. One way to complicate the surveillance of this is to use
certain fonts and line walls or equipment with different gauges of copper mesh wire.
You can further enhance this posture by using special paints, which block radio
transmissions.
Radio waves will look for a leak or break, so be careful of defensive
applications. One-way window tints can help in blocking signals. Since an
electronic device could generate some heat they can be detected in another way.
The use of a thermal imagery device can detect and actually see minute amounts of
heat radiated for your viewing. You can hide the heat signatures by using creams or
neoprene. Technology exists to collect information from blinking LEDs of modems,
routers, print servers and similar devices. You can only see some general blinking
but with the use of properly tuned optics, filters, oscilloscopes and good timing you
can discern much more. One of the LEDs on your keyboard can be altered to blink
while you are typing in a fashion similar to Morse Code. You can also use a tap in
the keyboard that sends out radio waves again similar to Morse Code and no anti-
virus software will ever be able to find it. Even when a CRT computer monitor is
facing a wall the light can be in a sense read by its flickering emanations from some
distance. A good defensive measure is to buy new LCD flat panel types.
Another approach to attacking FAX machines is to simply record the noises it
makes and play it back to another machine. I used to do this for a client so they
could keep a record of all the faxes they made and received. There are creative and
potentially illegal defenses against wiretappers and Peeping Toms. One is to
transmit an extremely high pitch down the wire, thereby rupturing the listener's
eardrums. I knew someone who once sent a powerful electrical spike down his
phone wire thereby destroying his divorced wife's recorder.
By the way, this leads to another topic-expect the device to be discovered
someday. Don't leave your fingerprints on it. He found it and had it dusted, thereby
producing some prints. My friend used this as leverage against the Private
Investigator that planted it. Advice to Private Investigators, a word to the wise: if you
do this part-time, hire someone who does this full-time. This P.I. lost his license
and almost went to jail. The lawyer who recommended him got into a lot of trouble
as well. He received some unwanted attention from the Feds because of his
telephone dealings went across state lines and also happened to involve the Post
Office.
There is another budding field related to this topic called Protective
Intelligence. Currently there are only a few experts who do this kind of work.
A laser or an infrared beam can be used at a considerable distance from a
target building. Conversational sounds can vibrate unto solid objects such as
windows. The beam's reflection varies in relation to the movement to the window,
which is received and converted back into something audible. To mask the sounds,
you could attach a vibrating device (basically an altered electric razor) to the
window.
Of course if the window is open, then a laser can target another object instead
of the window. A beam of light or laser can be directed to go through a window
onto a solid object thereby nullifying such defensive measures again. Generally you
really can't detect such attacks unless the laser, infrared or light beam is being used
that moment. Certain materials can be used to detect IR emissions, as well as the
use of passive night vision gear. Certain fabrics or even a curtain may actually show
the spot where a beam of light or laser is being focused. Unless the room is dusty or
you have an artificial can smoke, you can follow the beam up to a point and
guesstimate it's location. One type of optical bug is an infrared transmitter. When
placed in the area of interest for transmission of the conversation to an infrared
receiver which will then translate the conversation into an audible format.
Many of these same procedures used can be applied to locating hidden
cameras. A relatively new device uses a series of lasers to seek out optics. This was
originally intended to locate snipers by bodyguards.
I have listed the techniques, counter-measures and then the counter to the
counter-measures to prevent any false sense of security. Usually constant vigilance
is your best weapon besides knowing what to look for. Even if you find a "bug
sweeper" with good credentials, certifications and experience, ask them detailed
questions. Not just to test them but also for your own peace-of-mind. This makes
our job easier and we appreciate greatly when dealing with knowledgeable
customers.
Alarm System: Glass Break Detectors
Alarm System Glass-break detectors- Glass-break detectors are also known as "Audio Discriminators".
They are a perimeter device because they catch a burglar attempting to make entry into your home or business as opposed to walking around the interior and being picked up by a motion detector. They are available in both hardwired and wireless versions. The detector mounts in a wall or ceiling and listens to an area approximately 35 feet in all directions. They do not hear through walls or around corners or into a room because the door is open. The more windows you have in a device's area of protection, the better the value. Some examples of good coverage are as follows.
Securing Home Water Supplies; Conservation of Water Planning
Generally when it rains the water runs off the house and yards into the gutter and into pipes or storm drains which feed it into the river, stream or ocean. This conventional approach is problematic in that many of the countries regions are in severe drought. As we expand our population base we will see issues where the growth and water usage far exceed the regional annual rainfalls. This will indeed over tax the water supplies and cause issues with exacerbated droughts and lengthy recoveries. Eventually if kept unchecked we will be in perennial drought in most of our nation.
Security Alarm System Motion Detectors
Passive Infrared Motion Detectors- These detectors are also known as PIR detectors. The technology they utilize is "passive infrared". The device is mounted on a wall or in the corner of a room. It sends invisible fingers out into the covered area in several layers. The top layer goes the furthest and averages about 60 feet straight ahead and 35 feet on the sides.
Turn Your Home Into A Fortress
The best way to turn your home into a fortress is to carefully and strategically consider all your options. First you need to make a layout of your property and look at an aerial diagram of your home. Then you will need an aerial of the neighborhood, you can go to Google maps for this. Aerials pictures can provide you with possible escape routes of burglars. Drainage ditches, side roads, school playgrounds and wooded areas. You can also get an idea of every possible way the burglars might try to park a moving van without being seen or without being noticed. Often burglars look for areas where they can park a van or pick-up undetected for hours while they load up your prize possessions.
Alarm System Keypads
The keypad is the device you and your loved ones will interface with daily. It is typically placed at one or more of the following locations:
Home Security: Your Yard is the First Line of Defense
You may not believe it but most burglars do not plan their break ins. They are crimes of opportunity. They pick what appears to be a simple target. If they see a greater risk than they anticipated, they move onto a safer target. Therefore the more effort you take to keep your home from seeming to be a simple target, the safer you will be.
Security Cameras For Your Peace of Mind
The reasons for installing cctv cameras are the same whether you own a home or business. Protecting your property, family and employees is probably at the top of your list of priorities. You're not the only one that feels that way. Sales of home and business security systems have exploded in recent years. Even before 9/11, security system sales were on the rise. After the terrorist attacks, sales of home and business security cameras rose by as much as 20% over the course of three months.
How to Use a Fire Extinguisher
Millions of people everyday rely on fire extinguishers to put out minor fires which start in the home. Fire extinguishers contain a powder which is known to instantly put out a fire and prevent it from spreading any further. In 2004, fire extinguishers saved over 25 lives in the United States and prevented over 1,500 injuries. Fire departments all over the world encourage home owners to have at least one fire extinguisher in the home at all times. That said, studies show that approximately 80% of homeowners do have at least one in their home, but the question is do they know how to use it?
Numbers That Can Save Your Life
It's one of those things we don't give a second thought about. Many of us move into a house and never even change the number that's on the house. Why should you, it's the right number and that's all that matters. Well it may be the right number but can you see it at night or from the road? If there is an emergency and you have to call an ambulance, you certainly don't want them wasting valuable seconds looking for your home. Having a visible house number both day and night is critical.
