Lock picking is the activity that opens a lock without the proper key. When we are thinking of it, usually we are associating it with illegal activities. But that isn’t always the case!

Let’s think for example what we can do if we have lost the house key or if we have locked ourselves outdoors. If we live on the ground floor we could jump through the window (if it’s not open we can easily break it with a stone). But if we are not, we either unlock the door or… break it (which is not a cheap solution). With a bit of talent and an unsophisticated lock, we can manage to unlock it ourselves. Though the reality is not quite like in the movies (when a door is unlocked in a couple of minutes, just in time for the hero to save the heroine). The best solution is to call for a professional locksmith, who is trained to deal with these situations. Read more…

Before departing for your much earned holiday be wise and review your home security. The latest figures from the FBI show a burglary occurs every 15.4 seconds in the USA. The majority of these break ins take place when the householder is away from the home. A great number of these burglaries could be prevented by beefing up your home security and installing a home security system.

The installation of a home security alarm, and home security surveillance cameras is one of the most common and effective ways to improve the security of your home instantly. Many of these home security products also have the option of home security monitoring.  But the installation of these devices does not guarantee you immunity, other steps and precautions need to taken to improve you overall security.

History

From the beginning of humankind people have felt the urge to protect what they possess. They start by covering the entrance of their caves with stones; later they hid their gold and jewels in the ground.

Then they discovered locks. These were first made of wood and rope. They served the purpose well, although they were not so nicely designed. There is a lot of historical proof which certifies the use of locks long before we could imagine. Even in the Bible (Old Testament, Books of Judges) we have frequent mention of locks and keys.

Types

In modern society we have keys and locks for everything: the house, the office, the car, the bike. We even have more than one key for the same building; keys and locks are so much a part of our daily routine that we don’t take them into consideration (or maybe we do that only when the ring of keys is too heavy to be placed in our pockets).

But we do give a lot of thought when we have to pick the type of lock or the type of key. Basically we are talking about mechanical locks (based on mechanical activation of the keys) electro-mechanical locks (can be both mechanical or electrical activated, but usually the key is replaced with numbered buttons that have to be pressed) and electrical locks (activated by a card key that has a particular code, programmed to be read by a card reader which is controlled by an automated central or a local processor).

How to pick the lock?

It is not as complicated as we think, but also not as easy as it appears in a lot of movies. Some say that this requires both art and science. We have to have a good knowledge of the lock mechanism and, some practice.

Firstly we insert a tension wrench in the lock (a screwdriver for example) and, with a slight pressure, turn the plug (the lock cylinder) like the proper key would have done (we have to figure out what is the normal direction for the key to be turned). It will help create a small place between the lock pins (placed inside the lock). Then we have to insert a lock pick in order to lift them up (like the proper key will do when inserted in the lock). Doing this and continuing to apply pressure on the tension wrench we will hear a slight click (made by the pins when they fall in the right position) and the lock will be unlocked.

For unsophisticated locks we can use a metal hair pin as a lock pick. But professional locksmiths need an adequate pick tools kit. Basically this contains a tension wrench (they have different shapes and sizes) and several picks(long pieces of metal which are curved up at one end). Some can use an electrical pick gun (contains long pieces of metal and when they vibrate push the pins up and unlock the lock).

Re keying lock

The process of re keying is quite simple (takes couple of minutes) and it shouldn’t be confused with the process of replacing a lock. Actually it consists of disassembling the lock cylinder and replacing all the old lock pins with new ones, to match the new key. Then the cylinder is reinstalled in the lock!

When for example a member of the family loses the house key we can assume that a burglar has it. We should immediately re key the house lock to prevent a potential theft. It doesn’t cost a lot in time and money, but it can spare us a big stress. The same procedure is advisable when moving into a new house/apartment.

The better the lock is, the harder it will be for a burglar to break in!

Now that you’ve weathered the winter, the door is open for you to focus on the maintenance of your home-not only the inside of your home but outside, too, making sure the house is safe and properly maintained. Doing this will help to prevent safety risks and costly repairs in the future. Dan Steward, president of Pillar To Post, North America’s largest home inspection service, offers these suggestions:

Inspect the deck: Wooden decks can become damaged and corroded from the harshness of winter. See if nails or screws are popping up. Clean the deck and seal it. Check electrical outlets and extension cords: Replace any loose-fitting plugs or frayed extension cords to prevent a fire hazard.

Unlike an overzealous reporter, who shoves his microphone into your face in his efforts to get your take on the latest, breaking news story, there is a multitude of reasons why you might just want to keep your listening devices a secret. One of the many ways in which you can do that is by using listening devices that look like a pen.

These clever little devices are actually very sensitive pen microphones, and when worn in a pocket on your shirt or jacket, are easily mistaken for the real thing. One such listening device is permanently stowed inside the clicker part of a Bic pen and it will work with virtually any recorder that contains an external microphone input with power. Plus it is ultra high sensitive. But you don’t have to just use these great pen mikes just for covert purposes. Granted, if you are standing near someone and need to secretly listen to their conversation, these pen mikes are great.

But there are lots of other reasons to use these sensational listening devices as well. Let us say that you are attending a lecture and you want to record it so that you can carefully go over it later at home when it is time to study. By wearing this hands free device you can do so easily. Or what if you are planning to attend a live music concert and you want to make a recording, you can be sure that by using these particular listening devices, you will get an excellent recording with clear, crisp sound, and deep bass.

Your home is a safe haven from the world, a place to relax and unwind with family and friends. Unfortunately, hidden dangers may be lurking behind the walls that threaten your safety and that of your loved ones. That’s why it’s a good time to find out just how safe your home is from electrical hazards.

According to the National Fire Protection Association, there’s plenty of reason for concern: Nearly 32,000 fires in the home were caused by faulty house wiring or damaged wiring devices each year between 1999 and 2002. However, there is something you can do to safeguard your home from dangerous electrical hazards. The Leviton Institute recommends that with May being National Electrical Safety Month, homeowners conduct an inspection of their home and outdoor areas as part of their regular spring-cleaning projects.

First, make sure pool pumps, hot tubs and outdoor appliances that require electricity are plugged into GFCI-protected outlets with weatherproof covers. Ground fault circuit interruptors safeguard you and your loved ones from dangerous electrical shock. GFCIs detect when current is leaking from an electrical circuit to ground and automatically shut off the power at the receptacle. They have saved thousands of lives since their introduction in 1972. When choosing a GFCI, it’s important to ensure the device is stamped with the UL logo.

In addition, kitchens, bathrooms, laundry rooms, or any other place around the house that has a water source within six feet of the receptacle needs GFCI protection. Check all outlets and switches for cracks, broken parts or loose-fitting plugs. Replace defective devices immediately, as well as those that feel hot to the touch. You should also inspect all power cords and extension cords: Those showing signs of cracking, fraying or obvious wear should be replaced immediately. Never run extensions under rugs, carpets or furniture where damage can hide.

Make sure outlets are not overloaded. Most household outlets are typically rated around 15-20 amps. Plugging too many appliances into one outlet can exceed that rating and create a fire or shock hazard.

When you use an extension cord, always plug the appliance into the extension cord first before plugging the extension cord into the outlet.

The chances are good that the person sitting next to you may have been a victim of a crime. Statistics indicate that 8 out of 12 Americans will become victims of a crime at least once in their lifetime. Most people think of violent crimes-rape, assault, robbery-when they think of victims.

But not all victims experience crimes of violence. According to the Office for Victims of Crime, frauds, identity theft and financial schemes victimize millions of Americans each year. Consumers fall prey to phony investment scams, get-rich-quick schemes, foreign lotteries, telemarketing fraud, Internet scams and identity theft every day. Millions of hard-earned dollars and life savings of victims line the pockets of scammers, who have no regard for their victims or the damage they’ve done to their lives.

Last year, 10 million Americans became victims of identity theft, according to the Better Business Bureau, with a loss of over $50 billion. Insurance frauds cost the average family $400-$700 per year in higher insurance premiums. And fraudsters in the multibillion dollar telemarketing industry target older Americans, with an estimated loss of over $500 million.

Victims often feel helpless in the aftermath of a crime. They feel alone and isolated by the crime and many are financially devastated. If you or someone you know or love does become a victim of a financial crime or any other type of crime, there are countless professionals and volunteers who stand ready to help cope with the consequences of the crime, to offer support, and to provide guidance that can help victims better understand their options.

The good news is that there are laws ready to protect victims. The Federal Crime Victims’ Bill of Rights was created to give victims a proper place in the criminal justice system, ensure they have the opportunity to be heard and provide assistance to further their recovery process. Most states also have victims’ rights laws for cases handled in the local criminal justice system.

Are fake security cameras effective?  The answer is a resounding “Yes.”

Fake security cameras have helped to prevent many crimes.  Mounted in high profile, totally visible locations, these cameras are not hooked up to anything, they mostly operate for a long time on batteries and sometimes have a few flashing lights or other obvious characteristics to make them look as if they are doing something.

Many a would-be robber has changed his or her mind about entering someplace illegally after spotting one of these dummy security cameras looking right at them. With today’s technology, an inexperienced thief really has no way to know whether or not he’s looking at a wireless, state of the art surveillance device or a fake security camera. Some of them actually pan back and forth, although these require more frequent battery changes.

Fake security cameras are especially effective in areas that you expect to be covered by security cameras. For instance, many of the cameras in subway stations around the world are fake security cameras and nobody can tell the difference. During hard times, when the crime rates inevitably rise and cities are strapped for cash, the ratio of fake cameras to real ones was about 2-to-1 in some metropolitan areas.

Knowing that the fake cameras would be regarded as real, the fakes were sprinkled in among the real ones to provide an extra incentive for would-be robbers and thieves to practice their trade in another location. Except for the lack of recorded footage provided by the real cameras, dummy security cameras are almost as effective in reducing crime rates in subways as the real ones are.

Only sophisticated thieves can tell — at a distance — whether they are being observed by a real security camera.

Home Security System are used throughout the United States, people know what Burglar alarms are and what they are used for. Nevertheless they may not know how they operate. Let?s see how this protection system works in detail.

The Circuit

Home Security Systems are a simple electric circuit. To open or close a light, you simply throw a switch. In a burglar alarm it?s the same except the switch detects the movements of the intruder such as the opening a door or window.

Two categories

In a closed-circuit system, the electric circuit is closed when the door is shut. This means that as long as the door is closed, electricity can flow from one end of the circuit to the other. But if somebody opens the door, the circuit is opened, and electricity can’t flow. This triggers an alarm.

In an open-circuit system, opening the door closes the circuit, so electricity begins to flow. Also in this system, The Alarm is triggered when the circuit is completed.

Magnetic sensor
A magnetic sensor in a closed circuit consists of a few simple components.

- a battery powering a circuit
- a spring-driven metal switch built into a door frame
- a magnet embedded in the door, lined up with the switch
- a separately-powered buzzer with a relay-driven switch.

Control box

The control box is hooked up to one or more alarm circuits, but it also has its own power supply. Once the alarm is triggered, the control box won’t cut it off until somebody enters a security code at a connected keypad. In most installations the control box is kept in a veered place so that the burglar can’t even think of disabling it then the alarm goes off.

You can help avoid electrical shock, burns and fires by beginning your year-round electrical safety awareness efforts now. This is the word being put out by the Electrical Safety Foundation International (ESFI).

“Despite the fact that improved product safety engineering, standards and electrical codes have reduced electrical hazards, thousands suffer from electrical shock and fires each year,” said ESFI President Brett Brenner.

To increase electrical safety awareness and protect those at home and in the workplace, ESFI has developed an electrical safety tool kit that includes statistics on electrical hazards and recommendations to avoid electrical shock, burns and fires. Read more…
