Hello, Community!
Have a nice day to you!
This topic describes the method for handling image blur problems of motorized zoom-lens box cameras.
Motorized zoom-lens box cameras include IPC6112 series and IPC6122 series.
Solution
Manually Adjusting the Focus
This topic describes how to manually adjust the camera focus to adjust the image definition.
On the camera web page, click Preview to access the video preview page.
On the control panel in the left pane, click the buttons for adjusting the focus, as shown in the picture.
The manual focus adjustment buttons are
and .
If the video image changes from blurry to clear and then from clear to blurry, there is a definition point. In this case, you can adjust the focus to the definition point.
If there is no definition point, go to the next step.
Check whether the c- or cs-mount lens is incorrectly used
Lenses can be classified into C-mount and CS-mount lens. If a C-mount lens is to be installed in the CS mount, a C/CS adapter must be used. Otherwise, a fault may occur on the camera.
Check whether the lens mount matches the camera.
If a C-mount lens is to be installed in the CS mount, a C/CS adapter must be used, as shown in the picture.
If a C-mount lens is used and the camera mount is of the C type, go the next step.
If a CS-mount lens is used and the camera mount is of the CS type, go the next step.
Check whether the camera lens is blocked
Image blur will occur when the camera lens is blocked by an object.
Check whether the camera lens is blocked by an object onsite.
If yes, remove the object.
If no, go to the next step.
Check whether the video image is clear.
If yes, no further action is required.
If no, go to the next step.
Adjust the camera surveillance distance
If the distance between a camera and an monitored object is less than the minimum surveillance distance, the camera lens cannot be focused, resulting in image blur.
Check the distance between the camera and the monitored object on the site or through live video.
If the distance between the camera and the monitored object is less than the minimum surveillance distance, adjust the camera installation angle or location to enable that the distance between the camera and the monitored object is greater than the minimum surveillance distance.
If the distance between the camera and the monitored object is greater than the minimum surveillance distance, go to the next step.
Check whether the video image is clear.
If yes, no further action is required.
If no, collect logs and contact Huawei technical support engineers for assistance. For details about how to collect logs, see Collecting Information and Seeking Technical Support.
Adjust the lens aperture
A too large or too small aperture may result in image blur.
On the camera web page, click Preview to access the video preview page.
On the control panel in the left pane, click the buttons for enlarging and narrowing the aperture, as shown in the picture.
If the video image becomes clear after aperture adjustment, no further action is required.
If the video image is still blurry after aperture adjustment, collect logs and contact Huawei technical support engineers for assistance. For details about how to collect logs, see Collecting Information and Seeking Technical Support.
