LONG RANGE ADVANCED
SURVEILLANCE SYSTEM
  
 
 
Benefits
Conduct 24 hours reconnaissance
and surveillance missions.
Detect targets, outside direct fire range.
Suitable to install on Navy vessels and Grand Vehicle .
Identify and pinpoint targets
Before they become threats.
Use of sophisticated digital image processing for overlay reticule and optional target tracking, or dismounted on tripod
     
 

The LRAS4 with optional laser range finder and infrared forward looking system is a full automated advanced long–range surveillance systems for boarder security , army scout and surveillance purpose providing the real time capability to detect , recognize, identify and pinpoint far- target locations.

The LRAS4 bridges the gap between currently fielded system and the future scout and cavalry system.

The LRAS4-1 system is a new version of LRAS4 by changing the optical lens to zoom lens which provides more magnification, better resolution and eliminates the finder lens system.
Lens focal length : 85 to 1200 mm (f/4.0)
