UAVs have become inexpensive, widespread, and quiet.
Standard security systems cannot detect them.
Specialized sensors are required that can:
  • detect small targets;
  • operate in complex environments;
  • provide data for automated response.

Solution Portfolio
UAV Detection Radar

Short- and medium-range radar systems optimized for detecting small low-flying targets
Key characteristics (approximate but representative):
  • Detection range: up to 3–10 km
  • Detection of small targets with low signature
  • Azimuth and elevation measurement
  • Radial velocity measurement
  • Tracking of up to 50–200 targets simultaneously
  • Dynamic update rate
  • 24/7 operation
Advantages:
  • all-weather capability
  • independence from lighting conditions
  • primary threat detection sensor
Acoustic Detection System

An array of directional microphones with algorithms for isolating UAV acoustic signatures.
Characteristics:
  • Detection range: up to 500–1500 m
  • Direction finding
  • Classification: UAV / bird / transport
  • Operation in urban environments
  • Low power consumption
  • Autonomous deployment
Advantages:
  • detects small UAVs without radio signals
  • operates where radar is limited
  • improves accuracy in multisensor operation
Video Analytics and Optical Modules

PTZ cameras with UAV detection and tracking algorithms.
Characteristics:
  • Automatic target tracking
  • Optical and thermal imaging channels (depending on configuration)
  • Detection of small objects
  • Integration with radar and acoustic systems
  • ONVIF / RTSP support
Advantages:
  • visual confirmation
  • reduction of false alarms
  • collection of evidential records

All data is aggregated within a unified platform.
Electronic warfare (EW) initiates target suppression.
Systems can:
  • operate autonomously;
  • operate in pairs;
  • operate in a full multisensor configuration.
Proprietary Radio Communication
All modules are unified through their own secure radio network:
Features:
  • independence from external internet;
  • fault tolerance;
  • operation in field conditions;
  • channel encryption;
  • scaling to a distributed network.
The system continues to operate even if external communications are disconnected.
