13 Limits of the System
The following limitations have to be taken into account when using the
device:
•
The autofocus system of the camera preferably focuses on high-contrast
objects in the captured scene. However, when the infrared (IR) LEDs are
enabled, the continuous autofocus system automatically focuses on
objects in the captured scene that reflect IR light very strongly and directly
into the lens, such as traffic signs or license plates. Other areas and objects
in the image may then be out of focus.
•
At an object distance of less than 10 meters in combination with a high
zoom level (more than 25 times), the autofocus speed may decrease.
This is due to technical reasons and does not constitute a defect.
•
If the camera is tilted up to the maximum position at the lowest zoom
level (wide end of the zoom range), parts of the camera body may be-
come visible in the outer image areas.
This is due to the lens design and does not constitute a defect.
