and then resizing it back to the pixel size of the original image —a process called interpolation. Digital
zoom simulates optical zoom, but the digitally zoomed portion will have a lower quality than the
original image.
Is digital zoom relevant for PTZ cameras?
When viewing live video from a pan-tilt-zoom (PTZ) camera, you can use the PTZ camera's own
optical zoom features, so digital zoom is not highly relevant for PTZ cameras. You can, however, use
the digital zoom feature if, for example, your user rights do not allow you to use the PTZ camera's own
optical zoom features.
Why can't I see any navigation buttons?
If the camera you are viewing video for is not a PTZ camera, you will only be able to zoom in on an
area of the image and you will only see the zoom buttons. Once you have zoomed in on an area of the
image, you will have access to the PTZ navigation buttons, which let you navigate within this zoomed
area.
PTZ and 360º lens images
Use of 360º cameras is not supported by all surveillance systems and some 360° cameras are not
supported by the 64-bit version of Microsoft Windows. Depending on your user rights, access to PTZ
controls from some cameras may be restricted. PTZ features may be limited when connecting to
selected surveillance systems. For a detailed outline of the features available on your particular
system, see the XProtect Comparison Chart on:
www.milestonesys.com .
360° lens images
If your views include 360° cameras or lenses, you can navigate 360° cameras images by clicking
either the arrow mouse pointer (the virtual joystick) or the PTZ navigation buttons that appear inside
the image (some types of 360° cameras have their own zoom buttons). The PTZ middle navigation
button lets you quickly move the camera to its default position. Zoom in and out using the plus and
minus buttons. If your mouse has a scroll wheel, you can use scroll to zoom in and out; click the scroll
wheel or middle mouse button to return to the default view.
The PTZ navigation buttons and the virtual joystick mouse pointer
On individual mice, the scroll wheel may have been reserved for special purposes, in which case
zooming may not be possible. Refer to your mouse configuration manual.
You cannot use presets (see "Select a PTZ preset" on page 112) for navigating 360° lens images but
you can save a favorite position.
