NOTE: The difference between optical and digital zoom is that
optical zoom uses the lens within the camera to draw the image
closer via zoom in or out to achieve the desired effect. Optical zoom
remains the same quality and full resolution of the zoomed image.
On the other hand, Digital zoom takes a portion of an image and
expands the partial image to the full size of the original image;
therefore, the image quality will be reduced.
G/V/T Model:
For these models, maximum 12× digital zoom function is allowed to be
enabled. The default setting is <ON>.
P/M/S3/S4/S5/S6 Model:
For the three models, Digital zoom ratio is adjustable from <02> to <12>.
The default setting is <OFF>. For P model, if Image Stabilization function is
turned on, it will limit the effect of Digital Zoom.
• SLOW SHUTTER
The shutter speed determines how long the image sensor is exposed to
light. To see clear image in a dark environment, please enable Digital Slow
Shutter function and select a slower shutter speed.
G/V/T/S3/S4/S5/S6 Model:
As enable the Digital Slow Shutter function, the Dome Camera will
automatically adjust the shutter speed basing on the light condition of
installation environment. It enables users to see objects in a dark
environment under 0.1 lux.
P/M Model:
The shutter speed is adjustable in P and M models. With the slowest shutter
speed, users can see objects in a dark environment under 0.1 lux or see
smooth video image with a higher shutter speed. For the M model, the
options are from <1/2> to <1/60> (NTSC) and <1/1.5> to <1/50> (PAL). For
the P model, the slow shutter speed is adjustable from <1> to <1/60>
(NTSC) and from <1> to <1/50> (PAL).
NOTE: For P and M models, the Digital Slow Shutter function is
conditional on 1) shutter speed: ＞ 1/50 or 1/60; 2) in AE AUTO
mode; 3) Image Stabilizer function is OFF.
