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/RZ30P 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/RZ30P
clearly demonstrating the advantages of network
cameras, Sony now explores the possibilities of remotemonitoring applications even further with the introduction
of its new network camera, the SNC-Z20.
The SNC-Z20 incorporates a highly sensitive 1/4 type CCD
with Exwave HAD
Images are compressed using the industry standard JPEGcompression 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*
resolution is just one of the many capabilities of the
SNC-Z20. Its built-in web server allows images to be
viewed and controlled from a PC running a standard web
browser or the optional Sony IMZ-RS Series Intelligent
Monitoring Software. The SNC-Z20 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-Z20 is the right
choice for network monitoring applications.

Remote Monitoring/Control Over
Networks
The SNC-Z20 is equipped with a 100BaseTX/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-Z20 camera. And, by installing
the optional IMZ-RS Series Intelligent
Monitoring Software, up to 32 cameras can
be simultaneously monitored and controlled
from a single PC. The images from these
cameras can also be recorded to the PC's
hard drive. In addition, images can be viewed
from a Personal Digital Assistant (PDA)*
(see Fig. 2).
* Please contact a local Sony office or authorized dealer for
recommended PDAs.

*1 In the following text, “SNC-Z20” refers to both the SNC-Z20N (NTSC model)
and the SNC-Z20P (PAL model).
*2 The SNC-Z20N offers a maximum frame rate of 30 fps while the SNC-Z20P
offers a maximum frame rate of 25 fps. In order to achieve the maximum
frame rate, adequate PC processing power and network bandwidth are
required.

High Frame Rate
The SNC-Z20N produces images with a
maximum frame rate of 30 fps while the SNCZ20P offers a maximum 25 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-Z20
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-Z20 incorporates a 1/4 type CCD with
Exwave HAD technology that produces highresolution images with excellent sensitivity. The
SNC-Z20N achieves a horizontal resolution of
470 TV lines, while the SNC-Z20P offers 460 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. To cover a wide angle
of view, an optional VCL-0637H 0.6x Wide
Conversion Lens can be attached.
Selectable Image Quality and
Size/Image Flip Function
The SNC-Z20 provides the flexibility to select
image quality and image size according to
network bandwidth. Employing the industrystandard JPEG-compression format, the SNC-Z20
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.
* The image size for the SNC-Z20N is 736 x 480 while the
image size for the SNC-Z20P is 736 x 544.
Day/Night Function and Slow Shutter
The SNC-Z20 offers a Day/Night function to
provide optimized sensitivity in both day and
night shooting scenarios. As the scene
illumination reduces 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
be cast into shadows. 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-Z20 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
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-Z20 enables the user to increase the SNC-Z20
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 Stick
card adaptor can also be used. In addition, the
SNC-Z20 is compatible with certain IEEE 802.11bcompliant wireless PC cards, allowing for wireless
network operation.
* Please contact a local Sony office or authorized dealer for
compatible PC and wireless cards for use with the SNC-Z20.

(Transparency Function or VISCA
The SNC-Z20 has a transparency function available via
the RS-232C interface. This allows external equipment
connected to the RS-232C port of the SNC-Z20 to be
controlled from a PC over the network. Also, the
SNC-Z20 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-Z20 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-Z20 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-Z20 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-Z20 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.
