High Frame Rate
The SNC-Z20N produces images with a
maximum frame rate of 30 fps, allowing for clear
and smooth frame-accurate images to be
viewed. The frame rate can be set to a fixed or
variable frame rate, which is automatically
adjusted according to the available bandwidth.
Network Security Features
IP Filtering
Using the IP-filtering feature, access to the SNC-Z20N
can be restricted to one or more groups of selected
users. Up to ten different groups can be established
by defining an IP-address range for each group.
Setting these groups restricts access to the camera to
the defined IP-address range, while denying access to
all other addresses.
Password Protection
User names and passwords can be assigned to allow
four levels of access. The administrator has complete
access/control of the camera, while the other three
levels can be set to limit user privileges to functions
such as zoom control, viewing, trigger control, etc.
High Picture Quality and High Zoom
Ratio
The SNC-Z20N incorporates a 1/4 type CCD with
Exwave HAD technology that produces high-
resolution images with excellent sensitivity. The
SNC-Z20N achieves a horizontal resolution of
470 TV lines. Its built-in auto-focus 18x optical
zoom lens enables the user to obtain clear
images over long distances. A maximum 216x
zoom ratio is available when the optical zoom
and 12x digital zoom are used together.
Selectable Image Quality and
Size/Image Flip Function
The SNC-Z20N provides the flexibility to select
image quality and image size according to
network bandwidth. Employing the industry-
standard JPEG-compression format, the
SNC-Z20N has a selectable compression ratios
between 1/5 and 1/60. Also, the image size can
be selected from four modes: 736 x 480, 640 x
480, 320 x 240, and 160 x 120. Images from
the camera can be electronically inverted
including the analog video output - allowing the
camera to be installed in a variety of locations
and positions.
Day/Night Function and Slow Shutter
The SNC-Z20N offers a Day/Night function to
provide optimized sensitivity in both day and
night shooting scenarios. As the scene
illumination decreases and the image darkens,
the infrared cut filter is automatically removed
and the camera switches to B/W mode,
achieving a minimum illumination of 0.01 lx
(F1.4, 50 IRE, Slow shutter OFF) - a drastic
improvement from 0.7 lx minimum illumination
in color mode. In addition, the slow shutter
mode provides a remarkable enhancement in
sensitivity by allowing the charge accumulation
period of the CCD to be extended to a maximum
of one second.
Backlight Compensation (BLC)
The Backlight Compensation (BLC) function
helps to overcome strong backlighting effects,
which often cause the subject of the image to
appear dark. The image brightness can be set to
adjust automatically to compensate for adverse
lighting conditions.
