Very Long Range Surveillance and Target Acquisition System

NERIO-VLR is a modular Electro-Optical (EO) Surveillance, Target Acquisition (STA), and Reconnaissance system designed to satisfy a broad range of current and emerging customer requirements.

These include:

  • Mobile STA and Reconnaissance
  • Border security and Critical National Infrastructure protection
  • Coastal surveillance
  • Air Defense and Counter-UAS

The NERIO-VLR boasts a two axis Pan and Tilt head with a high reliability slip ring to provide a continuous 360° by ± 60° Field of Regard. It can optionally operate in a multi-point tracking mode utilizing a closed loop low latency embedded video auto-tracker. NERIO-VLR utilizes the SLX SuperHawk Thermal Imaging (TI) camera for provision of a 24 hr operational capability, with 21.5° to 1.5° zoom field-of-view.
