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.

  • Highly sensitive RF receivers 

  • Passive 1–1000km surveillance missions 

  • Hostile neighbor monitoring

  • Land border crossing monitoring 

  • Coastal surveillance 

  • Port protection & smuggling 

  • Small & wide-area sensor networks 

  • EW integrations

Border security monitoring applications

Drone-defense-icon
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.
