Sony's New Fixed Network
Color Camera SNC-Z20N
— Making the Remote
Possibilities Endless
With a variety of network-ready products, Sony is leading
the way into the new world of network-based surveillance
and monitoring applications. In 2002, Sony introduced the
SNC-RZ30N Pan/Tilt/Zoom IP camera, offering the flexibility
to view scenes from anywhere across the globe over a
standard IP network. With the SNC-RZ30N clearly
demonstrating the advantages of network cameras, Sony
now explores the possibilities of remote-monitoring
applications even further with the introduction of its new
fixed network camera, the SNC-Z20N.
The SNC-Z20N incorporates a highly sensitive 1/4 type
CCD with Exwave HAD
TM
technology for superb picture
quality. Images are compressed using the industry
standard JPEG-compression format for efficient
distribution over a network. Equipped with an auto-focus
18x optical zoom lens, this camera can zoom in on small
or distant objects with exceptional clarity. Frame rates of
30 fps
1
at VGA resolution is just one of the many
capabilities of the SNC-Z20N. Its built-in web server
allows images to be viewed and controlled from a PC
running a standard web browser. The SNC-Z20N also
offers a variety of other sophisticated features such as
Day/Night mode, Slow Shutter, and Activity Detection
functions, ideal for remote monitoring operations.
With its network functionality, superb picture quality, and
sophisticated features, the Sony SNC-Z20N is the right
choice for network monitoring applications.
1 In order to achieve the maximum frame rate, adequate PC processing power
and network bandwidth are required.
Remote Monitoring/Control Over
Networks
The SNC-Z20N is equipped with a 100Base-
TX/10Base-T (RJ-45) interface and a built-in
web server. This allows a PC running a
standard web browser to monitor its live
images and control the camera without the
need for additional software or plug-ins
(see Fig. 1). Up to 50 simultaneous users can
access, monitor, and control the images of a
single SNC-Z20N camera. In addition, images
can be viewed from a Personal Digital
Assistant (PDA)
2
(see Fig. 2).

Explorer with Jeode plug-in version 1.9.1 (CPU: Strong ARM
206MHz or higher, 64 MB RAM or more).

FEATURES

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.

Versatile Interfaces
AC 24V/DC 12V/Power-over-Ethernet
Operation
The SNC-Z20N offers a choice of three different power
supplies. AC 24 V or DC 12 V can be supplied
through the standard power terminal. Power can also
be supplied via an Ethernet CAT5 cable from an IEEE
802.3af-compliant power supply system*. AC 24 V,
DC 12 V, or PoE (Power-over-Ethernet) is automatically
selected according to the power supplied.
* Network equipment capable of supplying IEEE 802.3af-
compliant power is required. Please contact a local Sony
office or authorized dealer for recommended network
equipment.
PC Card Slot* Fig. 3
A built-in PC card slot on the front panel of the
SNC-Z20N enables the user to increase the
SNC-Z20N’s storage capacity for post-alarm recording
by adding either a flash ATA memory card or an ATA
hard disk drive (HDD) card. IC recording media such
as a "Memory StickTM" media card with a Memory
Stick/PC card adaptor can also be used. In addition,
the SNC-Z20N is compatible with Cisco’s Aironet®
C350 series IEEE 802.11b wireless PC cards, allowing
for wireless network operation.
RS-232C Interface
(Transparency Function or VISCATM Protocol)
The SNC-Z20N has a transparency function available
via the RS-232C interface. This allows external
equipment connected to the RS-232C port of the
SNC-Z20N to be controlled from a PC over the
network. Also, the SNC-Z20N can be controlled with
the VISCA protocol from an external control device,
allowing local control of zoom and camera settings.
Analog Composite Video Output
The SNC-Z20N can output an analog composite video
signal from a BNC connector located on its rear panel
(see Fig. 4). This allows the camera images to be
directly recorded or monitored by connecting video
equipment such as time-lapse recorders, hard disk
recorders, multiplexers, and monitors.
Alarm Function
Activity Detection/Alarm Trigger
The SNC-Z20N is equipped with a built-in activity
detection sensor that can be set to trigger an alarm or
a switch through alarm-output ports. If a change in
luminance level is detected in the field of view, an
alarm is automatically triggered. In addition, the
SNC-Z20N comes with an alarm-input port to receive a
trigger from an external sensor.
Pre-/Post-Alarm Image Storage
With the internal 8 MB buffer or a memory card
installed in the PC card slot, the SNC-Z20N can store
hundreds of pre-alarm and post-alarm still images at
an alarm trigger received either from the activity
detection sensor or the alarm input.
Image Transfer using FTP/SMTP
The pre-/post-alarm images stored at the time of an
alarm event can be transferred to an FTP server, and
the still image can also be sent to a specified e-mail
address as a JPEG attachment, enabling the user to
see what happened when an alarm occurred.
