Additional Info

This compact, affordable infrared thermal camera is designed specifically for machine vision

It’s perfect for those applications that only require the benefits of a thermal image but don’t need exact temperature measurement.

Key Features of the FLIR A65

  • IR Resolution – 640 x 512 pixels
  • Extremely affordable and Compact
  • GigE VisionTM (fast image transfer via low-cost standard cables over long distances)
  • GenICamTM protocol support (generic programming interface for all types of cameras)
  • Power over Ethernet (PoE)
  • Synchronization (configure one camera as master and others as slave(s))
  • General Purpose Input/Output (GPIO)
  • High sensitivity < 50 mK – < 50 mK
