Qual-Tron, Inc. (QTI) has been providing unattended ground sensors to military and government agency customers since 1986. QTI systems feature an extremely reliable communication link which has been utilized by border professionals around the world. Border security applications include primary detection on avenues of approach, outside the fence, early warning and the cueing of other systems’ equipment to augment and enhance effectiveness and save power consumption. The robust design of QTI equipment makes it an ideal trigger device to compliment camera systems, ground radar systems, acoustic systems or even systems with higher levels of lethality. QTI produces a range of seismic, magnetic, passive infrared, break beam, break wire, hydrophone, acoustic and other more specialized sensors. QTI sensors and transmitters can boast of three years in the field without a battery change. QTI sensors possess a very covert profile as these sensors are designed to operate while buried or concealed, making visual detection nearly impossible. The RF profile of much of QTI equipment is designed for maximization of stealth and minimization of power consumption as each transmission sent is a non-repeating short burst message, making it nearly impossible to detect, locate and intercept.


Qual-Tron Inc. (QTI) is a major supplier of Unattended Ground Sensors (UGS). QTI has pushed the envelope developing extremely low power sensors. These power needs have made it possible for QTI sensors to remain deployed for as long as two years. QTI has networked its systems with many operations around the globe. QTI sensors are deployed on every Continent and with every major Command. QTI has deployed its sensors in areas of both hot and cold temperatures while producing outstanding results. QTI sensors have successfully performed, in these areas, for more than 30 years with excellent reliability.

QTI has always been a small family owned business. Striving to provide a technologically advanced product. QTI has proven that the outstanding communications capabilities, of its products, have produced results for the Warfighter, Special Operations, Border Security, National Parks, The ease of fitting into an existing network or creating a network, has made QTI a go-to brand for many organizations worldwide.

Technical Attributes

  • Extremely low power sensors that can provide up to two years of sustainable operations with a small battery package.
  • Combine a digital architecture with a broad base of features designed around a modular configuration and you have a Situational Awareness product base that will give you the flexibility to fit most any intrusion need.
  • RF communications that allow digital wireless interface from each sensor pushed into a variety of network architectures to transfer critical data to a destination (C3) for analysis and response evaluation.
  • Event management capability to enable the operator to make an informed decision for interdiction and apprehension.
  • Sensor designs that are small, durable, and proven in the field of operation. New QTI sensors have reduced dimensions, reduced power requirements, reduced footprint, and increased efficiency. QTI sensors have stood the test of time.
