1.2.7 Zooming
The camera has two zoom features. The first is an optical zoom that allows you to magnify images by up to 2.3× and a digital zoom feature that allows you to further magnify images by up to 2×, for a total zoom range of 4.6×. This feature is referred to in this document as the “4.6× zoom” feature. The 4.6× zoom feature can be used when:
–
Viewing video images on the single camera page
The second zoom feature is a 10× (by area) digital zoom. This feature uses the ActiveX Controls installed on your PC; when using this feature, the lens itself does not zoom. This means that while you are using the 10× digital zoom, another user can be looking at the same image with no zoom. This feature is referred to in this document as the “10× digital zoom” feature. The 10× digital zoom can be used when:
–
Viewing video images on the single camera page (when the 4.6× zoom feature is disabled)
–
Viewing video images from multiple cameras on the multi camera page
–
Viewing buffered MJPEG video images on the buffered image page
There are 3 ways to use the zoom features, as explained later in this section.
Note
•
As the digital zoom magnification increases, image quality decreases.
•
You can move the lens as normal (selecting a preset, using the navigation buttons, etc.) even when zooming.
•
If the 4.6× zoom feature is disabled for general users or guest users, or when zooming while viewing buffered MJPEG video images, the 10× digital zoom is available. The digital zoom magnification (×1.0–×10.0) is displayed briefly while zooming.
•
When [Tele End] is displayed at the top of the operation bar, the lens cannot zoom in any further. When [Wide End] is displayed, the lens cannot zoom out any further.
•
When using the optical zoom to zoom out, the lens zooms in slightly after the zoom out. This is a characteristic of the camera’s zoom feature, and is not a malfunction.
