I interviewed Albert Chen at the Three-In_One factory in Taipei to discuss the different video borescopes that they produced. This company has developed technology to place a video chip in the tip of their line of scopes for crisp video. They produce a wide range of optical instruments for government, security, locksmith and automotive applications. I spent three days with the owners of the company and was shown their latest technology including wireless applications.

See my interview with cfh6W_Sh16Q.

LSS+ Version 2007 will soon be released. This new edition contains four new disks: LSS+ Infobase, LSS102, LSS205, LSS206. In addition, the update to the DAME version will be available at ALOA on July 22. The Defenses Against Methods of Entry series contains sixty video files detailing many covert and mechanical bypass techniques. Twenty new video files have been added to this collection, including material on the new pick tool for Mul-T-Lock that can allow some of these UL 437 rated cylinders to be opened in under one minute.

DAME is only available to Locksmiths, law enforcement and security professionals. A summary of all video files for the LSS+ collection has now been posted in the LSS+ On-line tour.

There is a significant amount of new material in the latest edition of LSS+, including approximately twenty interviews with biometrics professionals in the U.S. and England. In addition, a majority of the Wendt collection of locksmith and bypass tools are now integrated into the Infobase. A comprehensive list of updates by chapter will be posted shortly.

A High Security Supplement will be available later this year that will detail advanced bypass techniques for UL and ANSI rated cylinders. This will be a must-read for security professionals who rely upon these standards.

The new edition of LSS+ will be issued on DVD and 2GB USB drive due to the increased size of the Infobases. New security updates have also been implemented by Folio to protect the information from unauthorized access.

Discounted copies of LSS+ will again be available at DEFCON 15.

HIGH TECH MODULAR STRONG ROOMS: When they are really after you or your valuables!


Marc Tobias interviews CitySafe’s CEO Karl Alizade at their facility in New Jersey in May, 2007 about their portable strong rooms and vaults and why they are sought after by the military, banks, diamond merchants, cash handling facilities, foreign diplomats, VIPs and even drug dealers.

CitySafe is a small innocuous company located in New Jersey, about an hour south of Newark airport. Their CEO has thirty years of experience in designing, building and opening safes and vaults. Karl routinely consults with major insurance companies in the U.S., UK, and other venues with regard to protection and burglary prevention of high value assets, and the analysis of burglaries and the resultant failure of safes and vaults.

His company produces a modular strong room, built around individual concrete panels for which CitySafe holds several patents. These safes can be transported on palates and easily constructed in the field in a matter of hours by two or three men. They can be much more economical than traditional construction techniques because of their cost and versatility and are the only type of strong room enclosure that can be installed within an existing structure such as an embassy, royal palace or private home.


The heart of the system is a special mixture of cement that is produced in Germany then refined in the United States. The compound will withstand pressures of up to 30,000 pounds per square inch. In layman terms, that is a lot! The concrete is set around an extremely strong re bar matrix, shown in the photographs below. If you need protection against rocket propelled grenades (RPG), small and large arms fire (like fifty caliber machine guns), explosives (including shaped charges), twenty-pound sledge hammers and gas-powered grinders, then this is definitely what you need for your government facility, power plant, business or private residence.

CitySafe produces custom-sized safes and strong rooms for a wide array of users including diamond mines, third world dictators (who are always worried about their safety and that of their family in a coup), military organizations, public utilities, large jewelry stores and precious stone processing facilities, banks, CEOs of large corporations, diplomats, embassies, cash handling facilities and residences of the wealthy, including drug dealers. Even they have families that they need to be concerned about in the event of a hostile attack or vendetta raid by the competition!


These photographs show methods of attack and the results. Note the matrix of re bar that fortifies the concrete liner.

The company has a large manufacturing facility and because the size of the enclosure is based upon the use of a standardized modular panel, they can produce strong rooms, personal safe rooms and vaults to any requirement with short delivery times. The company is also negotiating licensing arrangements in several foreign locations that will allow local military and security personnel to meet their needs on a more urgent and local basis.

Normally strong rooms are constructed of concrete which is the most secure against attack and does not degrade with age. The problem with this type of construction is that strong rooms and vaults must generally be created at the time of building construction and very expensive vault doors must be set, often with cranes. Obviously, once installed these strong rooms are not movable. In addition, at least thirty days is required for the concrete to set.

The alternative (and less secure) construction technique (and also less expensive) is to employ several layers of wood, surrounded by relatively thin sheet-metal walls. Wood has been used as an insulator for both burglary and fire proofing for hundreds of years. From the security perspective it can lead to real problems. Over a period of twenty years all of the moisture can disappear and the wood will virtually disintegrate, leaving no real protection whatsoever. Some of New York’s Fifth Avenue jewelry stores might want to pay attention to this issue, as Karl Alizade and other experts can attest after evaluating successful burglaries. Many are at risk and do not know it.


The photograph shows wood material that was virtually worthless in a UL listed strong room that was the subject of a burglary of a jewelry store in New York. Karl analyzed the crime scene and was utilized as an expert witness. UL rated this material and certified that it would resist penetration of a ninety-six square inch hole for thirty minutes. According to Karl, it took the New York City Fire Department about four minutes to cut a large hole through the material, as shown in the video.

The CitySafe platform have been tested against a number of threats, including small arms fire, thirty rounds from a Russian Kalashnikov 4.45mm automatic rifle AK74, Kalashnikov SVD super rifle 7.62 APmm, GP25 grenade launcher, 40mm (Russian military), Laws type anti-tank weapon (Russian military), Rocket propelled grenade RPG7, and a variety of explosives and super-attack tools like gas-powered grinders, long crowbars, and twenty-pound sledge hammers.

If you need a strong room, vault, or personal safe room for your family or staff that is impervious to most forms of attack and can be transported to meet individual requirements, then you might want to look at this unique system. The firepower that this concrete will stop is unreal.

During the final firefight, Al Pacino screamed at his attackers in the 1983 movie Scarface “come and get me.” If he had been in a CitySafe enclosure I imagine the movie would have turned out quite differently. But then, we would not have been able to enjoy the farewell plunge of his bullet-riddled body into his swimming pool.

Images from LSS+: The Multimedia Edition of Locks, Safes and Security

This month we feature images of Medeco Biaxial and M3 cylinders, in connection with the article regarding security vulnerabilities of the M3.

The Medeco M3 cylinder utilizes the Biaxial technology but adds another layer of security and key control with the introduction of a patented slider mechanism. This slider is controlled by one of twenty-six steps on the key and is moved into the precise position to allow the sidebar to retract. Note the gates on the sidebar. There are corresponding tabs on the slider that must be perfectly aligned.
