Long Range EO IR Gyro-Stabilized ISR System

The Guardian 4HD is a powerful medium to long range gyro-stabilized ISR camera system. Guardian’s flexible payload
configuration makes it a smart choice for a wide variety of platforms.


NVTS’s Guardian 4HD precision gyro-stabilized camera system delivers high definition imaging, long range optics and
precision targeting in a compact package.


Designed for in theatre operations, the Guardian 4HD delivers superior detection, stabilization, crisp imagery and
targeting data using our True HD Visible and Thermal Cameras.


Image Enhancement: This standard feature works on both Thermal and HD Visible Cameras
bringing out important visual details that otherwise would be “washed out” in a low contrast picture. Image
Enhancement is essential in hazy & low visibility conditions.


Edge Sharpness: This Guardian feature sharpens objects edges and resolution within the
video image for both Thermal and HD Visible Cameras, yielding a clearer and sharper video image.


Local AGC: This feature provides wide dynamic range of the video image for both HD
Visible and Thermal camera. The Guardian’s Local AGC feature is especially needed when the scenery has a wide
range of gray levels, such as when the imagery includes sea and sky, sea and land, burning objects, etc.


  • Multi-axis high performance gyro-stabilization using advanced sensor technology providing steady imaging
    in extreme conditions.
  • Dual on-board processors run a sophisticated Adaptive Kalman Filter (AKF) for superior static, dynamic
    inclination estimates, and inertial measurements.
  • True HD Thermal /Visible Cameras enables razor sharp recognition at long ranges.
  • On screen display enabling fast operator information assessments
  • Large Format HD 2.2 megapixel Visible with 30X Optical Zoom
  • HD Thermal 1.2 megapixel (1280 x 1024) Cooled MWIR delivers 4x the image resolution compared to the
    standard 640 x 480 resolution.
