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.

Performance:

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.
