DIGITAL ZOOM
This option allows users to enable or disable the 12× digital zoom. The digital
zoom is activated after the full optical zoom level has been reached.
NOTE:
The difference between optical and digital zoom is that optical
zoom uses the lens within the camera to draw the image closer by
zooming in or out to achieve the desired effect. Optical zoom retains
the full resolution and quality of the zoomed image. By contrast, digital
zoom takes a portion of the image and expands that portion to the full
size of the image; however the image quality will be reduced.
18×/26× Model:
For these models, maximum 12× digital zoom function can be enabled. The
default setting is <ON>.
23×/35× Model:
For these models, the digital zoom ratio is adjustable from <02> to <12>. The
default setting is <OFF>.
For 35× model, if Image Stabilization function is
turned on, it will limit the effect of Digital Zoom.

SLOW SHUTTER

To see a clear image in a dark environment, please enable this function and
select a slower shutter speed.
18×/26× Model:
When the digital slow shutter function is enabled, the PTZ Camera will
automatically adjust the shutter speed basing on the lighting condition of the
installation environment. It enables users to see objects in a dark environment
under 0.1 lux.
