Uncooled Thermal Cameras

• High solar rejection
• High penetration of smoke and many fogs
• MEMS-based, uncooled silicon detectors work well
• Lowest cost thermal technology

Representative Range Performance Options
14
Short/Medium Range Uncooled Cameras

• Typically used for ranges lt 2-3km
• Ideal for terrain-limited installations
• Ideal for border crossing walk-arounds

Multi-Sensor Dual thermal cameras day/night

Industry Trend
Rapid Migration to 640x480 sensors
Mid Format Detectors
Large Format Detectors
320 x 240 Pixels
640 x 480 Pixels
Having only 76,800 pixels to capture information
about the scene.
Having 307,200 pixels to capture information
about the scene.
What does this mean?
4x the resolution of mid format arrays. More
pixels means better image quality, creating
greater detection capability than mid format
sensors, which has created the move to high
definition.
17
Industry Trend
Advanced Signal Processing Yields Higher
Performance
A digital, thermal image has more information
in it than is obvious to the naked eye. The
detector can sense differences to 0.03C
Digital image processing allows us to apply
dynamic, regional contrast settings to enhance
human visual interpretation of events.
