Border security monitoring

Helping border agencies maintain territorial integrity through real-time situational awareness

Overview

Traditional approaches to border security involve physical security, electro-optical surveillance, and radar. While these methods are essential, they have drawbacks, including limited coverage, scaling challenges, and human error.

Illegal activity at borders is often aided by communications devices that emit RF signals, such as cell phones, push-to-talk radios, or even radars. Therefore, by using a network of receivers and exploiting these signals, border forces can detect, classify, and geolocate emissions. Automated, passive 24/7 RF spectrum delivers a vast amount of additional intelligence, improving situational awareness without being overtly defensive.

CRFS works with military border forces and border agencies to create passive ISR solutions capable of interconnecting land, air, and sea missions. These include vehicle, drone, and tethered drone integrations and support border agency and EW operations.

Border security monitoring applications

Detect unmanned aerial vehicles (UAVs)

RF monitoring systems detect and geolocate unauthorized and modified UAVs that may be used for surveillance, smuggling, or other illicit activities in border areas.

Passive air defense

Pasive RF monitoring across borders spanning thousands of kilometers can provide covert intelligence on hostile aircraft or ISR drones conducting reconnaissance missions.

National security

Closely monitoring borders gives border forces tactical advantages and strategic awareness—useful for both cross-border cooperation and countering potential threats.

Illegal immigration control

Spectrum monitoring can help geolocate and monitor the movements of individuals and groups attempting to cross a border without the correct documentation.

Smuggling & trafficking control

RF monitoring technologies help identify and intercept attempts to smuggle contraband, narcotics, weapons, and human trafficking across borders.

Border intrusion detection

Intrusion detection systems identify any attempts to breach border security infrastructure, such as fences, barriers, or walls.

Unauthorized border crossing detection

Monitoring systems detect and alert authorities to individuals or vehicles attempting to cross both land and maritime borders without proper authorization.
