Cleaning
Great care should be used with your camera's optics. They are delicate and can be damaged by
improper cleaning. The FB-Series thermal camera lenses and windows are designed for a harsh
outdoor environment and have a coating for durability and anti-reflection, but may require cleaning
occasionally. FLIR Systems, Inc. suggests that you clean the lens when image quality degradation is
noticed or excessive contaminant build-up is seen on the lens.
Note
Rinse the camera housing and optics with low pressure fresh water to remove any salt deposits and
to keep it clean. If the front window of the camera gets water spots, wipe it with a clean soft cotton
cloth dampened with fresh water.
Do not use abrasive materials, such as paper or scrub brushes as this will possibly damage the lens
by scratching it. Only wipe the lens clean when you can visually see contamination on the surface.
Use the following procedure and solvents, as required:
•
Acetone – removal of grease
•
Ethanol – removal of fingerprints and other contaminants
•
Alcohol – final cleaning (before use)
Step 1
Immerse lens tissue (optical grade) in Alcohol, Acetone, or Ethanol (reagent grade).
Step 2
With a new tissue each time, wipe the lens in an “S” motion
(so that each area of the lens will not be wiped more than once).
Step 3
Repeat until the lens is clean. Use a new tissue each time.
Image freezes momentarily
By design, the camera image freezes momentarily on a periodic basis during the Flat Field
Correction (FFC) cycle (also known as Non-Uniformity Correction or NUC). Every so often, the
image will momentarily freeze for a fraction of a second while the camera performs a flat field
correction. A shutter activates inside the camera and provides a target of uniform temperature,
allowing the camera to correct for ambient temperature changes and provide the best possible
image.
No video
If the camera will not produce an image, check the video connection at the camera and at the
display. If the connectors appear to be properly connected but the camera still does not produce an
Do not disturb or move camera during cleaning. The detection analytics on the FB-Series ID camera
are set and calibrated based on the exact position and camera angle. Inadvertent realignment may
require relocation and recalibration of detection regions.
