How Metal Gate Detectors and X-Ray Machines Work and why
Guardex gates and machines are uniquely different
and their operating technologies

Guardex is a worldwide leading brand in the security inspection field, holding multiple patents in x-ray imaging and metal detection technologies. As maintaining security becomes an increasingly challenging endeavor, Guardex hopes to help its partners minimize and control this endeavor by deploying Guardex products and solutions to keep ahead of security risks through innovative, technologically advanced and high quality products and solutions.

To clearly identify the difference between Guardex and its competitors, we will start by explaining the basic operating principle of X-ray imaging; x-rays interact with matter, passing through it and being absorbed by the matter than scattering from it Matter with high density absorbs x-rays more than matter with low density, resulting in x-ray images being brighter where the rays pass through lower density matter and darker where the rays pass through higher density matter.

MULTI-COLOR IMAGING

Guardex has been leading the x-ray imaging technology for nearly three decades, delivering advancement in x-ray imaging after the other, the latest being multi-color imaging, allowing for the identification of organic, inorganic, metals, compound materials, and empty space helping screeners accurately distinguish materials to identify and eliminate potential threats.

ENHANCED IMAGING

Guarde4s enhanced imaging technology simplifies the screeners job considerably, allowing screeners to shuffle through multiple imaging enhancement technologies to identify potential threats mom accurately, by allowing standard multi-color imaging, reverse color imaging, black and white imaging, Pseudo imaging, variable absorption rate imaging, low-energy penetration imaging, high-energy penetration imaging, elimination imaging (organic or inorganic materials), magnification imaging region al interest ImegIng

MACHINE LEARNING

Guardex’s machine teaming technology allows x-ray machines to learn patterns, image shapes and material compositions to better identify the same items in the future. Guardex’s machine learning has three modes; image recognition training mode (to teach the machine to recognize certain objects), dangerous goods image insertion mode (to teach the machine to recognize similar objects as in images) and explosives and drugs auxiliary examination mode (allows the machine to filter its image recognition algorithm to focus on explosives and drugs).

SOLUTIONS FOR EVERY APPLICATION

Guardex offers an extensive range of x-ray machines with range of tunnel sizes, conveyor speeds, enhancement features and footprints including standard vehicle, bus and truck x-ray scanning machines with safe high-energy x-ray generators for deep imaging penetration, capable of seeing through metals without any clarity loss to inspect trucks and cargo shipments without the need to unload or inspect every container to accelerate the passing of vehicles through security checkpoints.

To clearly identify the difference between Guardex and its competitors, we will start by explaining the basic operating principle of metal detection; metal detectors utilize pulse induction technologies by using a coil of wire to send powerful, short pulses of current through the coil generating a magnetic field which is affected or interrupted by metallic objects, thus identifying their presence.

ENHANCED SENSITIVITY

Guardex’s walk through and handheld metal detectors deploy multi-grade adjustable sensitivity levels as well as multiple detection programs allowing for the fast and accurate detection of metals of different sizes and configurations even when concealed.

REMOTE MANAGEMENT

Guardex offers its own software platform to interconnect walk through metal gate detectors to a monitoring platform by multiple communication methods (RS485, USB, Ethernet) allowing for remote monitoring and management of machines.

SUSTAINABLE OPERATION

Guardex offers multiple options to ensure 24/7 sustainable operation of its walk through metal gate detectors by offering IP65 outdoor rated protection housings as well as twelve and twenty-four hour backup uninterruptable power supplies, ensuring the sustainable operation of gates even in the harshest environments.

Trace detectors are detectors with the ability to detect tiny or `trace” amounts of explosive or narcotic residue or vapors. Trace detection can easily be divided into three types based on the whether the material being scanned had come in direct contact with the explosive or narcotic or not, Guardex has developed its trace detection products to be able to detect explosives and narcotics in both contact cases and even in case of being contained in non-contaminated barrier.

DETECTION THROUGH CONTACT

When an individual or their belongings comes in contact with explosives or narcotics; tiny particles of these compounds contaminate the individual or their belongings, a sample is taken either by wiping the individual’s hands, clothes, or belongings with a swab. The swabbed sample is then inserted into a trace analyzer and tested for explosive or narcotic residue using ion mobility spectrometry which measures the travel speed of ionized particles to identify the type of material.

DETECTION THROUGH NON-CONTACT

Because of the limitations presented by detection through contact due to lack of residue or inaccessibility to samples, detection through non-contact has become the more prominent technology, offering multiple trace and vapor detection techniques, the most common is Pseudo Random Sequence Ion Gate Technology multiplexed with the Hadamard transform which enhances on the on mobility spectrometry technology

DETECTION THROUGH BARRIERS

In case explosives or narcotics am placed inside seemingly innocent metallic or non-metallic bottles, in such a case optical and laser technologies using electromagnetic infrared and radio frequencies are used to identify the material inside the barrier / container by exciting (or increasing the energy level of) the contents inside the barrier / container. So that the material emits electromagnetic signatures which the detector uses to analyze and identify the composition of the material inside the barrier / container.
