Long Distance Metal Movement Detecting Sensor

SNOOPER is the exclusive and innovative solution for detecting the movement of an iron object (guns, rifles, etc) from a long distance away. It can detect the sneaking movement of enemy forces in a forest, and a Hummer from 15 meters away.

SNOOPER is the perfect tip and cue sensor for military purposes and also can be utilized as an anti-terror system to protect citizens. 

This technology originated from the MAD sensor using Josephson effect in extremely low temperature, and MAGO technology entirely re-designed the sensor so as to need no cooling system and uses very low energy, and finally has made a long distance metal detector -  SNOOPER that is the smallest MAD sensor in the world. MAGO Technology has the top tier leading technology about the ultra precision magnetic sensor. Now SNOOPER is used for the security of borders, government entrance, surveillance of important facilities all over the world. 

SNOOPER can measure the nano level perturbation of Earth magnetic field that produced by the movement of ferrous materials.  It is not affected by rain, snow, leaves and wild animals, and reacts only to the movement of an iron object.

SNOOPER is the smallest MAD sensor in the world that can be easily connected to an IT device. It can be used for the detection of enemy movement for military purpose, and as a stealth metal detector for civilian to prevent terrors.

SNOOPER has the special kind of analog-digital hybrid detection structure, and also the signal processing unit that has a function of extracting exact target signal from micro-sized noisy signal stream.

Conventional motion detectors cannot be used in a forest because they also react to snow, rain, leaves and wild animals. Meanwhile, a SNOOPER reacts only to the movement of an iron material. The movement of an iron should belongs to a human, because iron is a human's tool. SNOOPER does not make a false alarm by wild animals.


SNOOPER-DP SYSTEM uses two of SNOOPER sensor that can be easily installed on the standard barrier pole, and the system detects the movement of an iron object that are passing between two sensors without a body check. 

SNOOPER-DP SYSTEM was developed to protect children and civilian from terrors and crimes, and it has an unique capability to cancel out the disturbance from a large-sized moving iron object nearby such as an elevator. The system is a kind of STEALTH INSPECTION SYSTEM.  People does not feel any inconvenience, and it gives security guys very important information about visitors.

SNOOPER-DP system can detect iron object that pass between two sensors in real time. SNOOPER-DP system has the specially designed analog-digital hybrid compensation structure against the effect from a large-sized moving metallic object nearby.  

SNOOPER-DP is the best hidden metal detector system for public safety WITHOUT BODY CHECK. It is possible to get both of that visitors does not feel any inconveniences and security guys get the important information about visitors including a VIP without sign of displeasure. The sensor of SNOOPER-DP was designed to be installed on a standard barrier pole.

SNOOPER can easily be interfaced to the user's system by LAN, USB and Wireless, etc. We have 4 types of basic package with different product composition each other, so customer can choose one of them for their own purpose and environment.

We also have the total solution of surveillance system with SNOOPER, please contact us. ( )



USB Package

SNOOPER USB package is the basic kit of SNOOPER. User can easily connect the sensor to a standard PC. This simple system can be used on a strategic point outside, corridors and under fences. SNOOPER is connected to USER's PC by an USB port, and do not need an extra power supply.
Composed with:

SNOOPER Sensor Head + USB Interface + PC S/W



Wired LAN Package

If you use a wired LAN package, you can easily connect SNOOPERs to your own conventional surveillance system by standard LAN interface, which makes the whole system empowered with an extra-ordinary function and special ability.

Composed with:

SNOOPER Sensor Head + Wired LAN Interface + Protocols



LAN / RELAY Package

LAN / RELAY interface has the function of SAC(Stand Alone Controller) for operating RELAY instantly on the board. User can easily build the system which has a function to turn on a light or to make a siren when a metallic object detected. 

The package also has the function of LAN connection, so user can build up a variety of security systems with this package.


SNOOPER LAN/RELAY Package obtained CE and FCC certificates. This package now contributes to the protection of Europian people from terrorism.  
Composed with:

SNOOPER Sensor Head + Relay/LAN Interface



Long Distance Package

The connection cable of a SNOOPER can be extended up to 1km with this package. The extender receiver embeds the SAC(Stand Alone Controller) to operate a relay and let the user notify with warning sound and LED. This package is the perfect system for front lines or borders.

Composed with:

SNOOPER Sensor Head + Extender + Extender Receiver

Option Modules

Besides SNOOPER Package, a variety of option modules are available for the user's applications, and it is also possible to build up the USER's own interface model.  Please contact us. ( )

Stand-alone Controller

Using stand-alone controller makes simpler system configuration, and it is easy to build up small and powerful security system with SNOOPER.

Wireless LAN Interface

Using the Wireless LAN Interface, user can install SNOOPER more conveniently.

RF TX/RX/Repeater

RF transmitter and repeater expands  communication distance with easy installation.
