Frequently Asked Questions
Common Issues
What should I do if the image shows motion blur or ghosting?
Image trailing may be caused by the following factors:
• Equipment moving too fast
• Observe the target moving rapidly
• Low device frame rate or exposure settings
It is recommended to stabilize the equipment and make appropriate adjustments to its settings.
Why are distant objects difficult to see clearly?
The clarity of distant targets is affected by the following factors:
• Lens focal length
• Ambient lighting
• Target size
• Atmospheric conditions (fog, humidity, etc.)
It is recommended to select the appropriate magnification or lens based on the application scenario.
Will lens fogging affect image quality?
Fog or condensation on the lens surface can degrade image sharpness.
Recommendation:
• Use a dry, soft lens cloth to clean the lens.
• Avoid frequent switching between environments with large temperature differences.
• Place the device in a dry environment.
Why is the image blurrier at the edges than in the center?
Some optical systems may exhibit slight edge blur at extreme fields of view; this is a normal optical phenomenon.
If the blurriness is quite noticeable, you can:
• Refocus
• Adjust the viewing distance
• Ensure the lens is free from contamination.
Why is the image too bright when using night vision devices during the day?
Night-vision devices are primarily designed for low-light environments; if used during the day or in bright lighting, the image may appear overly bright or overexposed.
Recommendation:
• Avoid using night vision mode during the day.
• Use the device’s Day Mode or Protection Mode
Is it normal for the device screen to flicker or briefly freeze?
Some thermal imaging devices perform automatic calibration during operation, which may cause the display to briefly flicker or freeze.
This is a normal phenomenon and will not affect the operation of the device.
