High Picture Quality and High Zoom Ratio
The SNC-Z20P incorporates a 1/4 type CCD with Exwave HAD technolo-
gy, offering high-resolution images with excellent sensitivity and achieves
a horizontal resolution of 460 TV lines. The built-in auto-focus 18x optical
zoom lens enables the user to obtain clear images even when enlarged. A
maximum 216x zoom ratio is available when the optical zoom and 12x dig-
ital zoom are used together. To cover a wide angle of view, an optional VCL-
0637H Wide Conversion Lens can be attached.
Remote Monitoring / Control Over Networks
The SNC-Z20P 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 brows-
er to monitor its live images and control the unit without the need for addi-
tional software or plug-ins. Up to 50 users can simultaneously access,
monitor, and control the images of a single SNC-Z20P camera. And, by
installing the optional IMZ-RS Series Monitoring Software, up to 32 cam-
eras can be simultaneously monitored and controlled from a single or mul-
tiple PCs. 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
2
(PDA). 
High Frame Rate
The SNC-Z20P offers a maximum frame rate  of 25 fps
1
, allowing 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-Z20P 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. Generally, 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.
Selectable Image Quality and Size / Image Flip Function
The SNC-Z20P gives you the flexibility to select image quality and image
size according to your network bandwidth. Employing the industry-
standard JPEG-compression format, the SNC-Z20P has a selectable
compression ratio between 1/5 and 1/60.  Also, the image size can be
selected from four modes: 736 x 544, 640 x 480, 320 x 240, and 160 x
120. Images from the camera can be electrically reversed upside down –
allowing the camera to be installed in a variety of locations and positions.
Day / Night Function 
and Slow Shutter
The SNC-Z20P offers a Day / Night function to provide optimised sensi-
tivity in both day and night shooting scenarios. As the scene illumination
reduces and the image darkens, the infrared filter is automatically
removed and the camera switches to B/W mode, achieving a minimum
illumination of 0.01 lx (F1.4, 50IRE, Slow shutter OFF) – a drastic improve-
ment from 0.7 lx minimum illumination in colour 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 1 second.
Backlight Compensation (BLC)
The Backlight Compensation (BLC) function helps to overcome strong
backlighting effects, which often cause the subject of the picture to be
cast into shadow. The picture brightness can be adjusted automatically to
allow for changes in lighting conditions, optimising the image intelligibility
under very adverse lighting conditions.
Versatile Interfaces
PC Card Slot
4
A built-in PC card slot on the front panel of the SNC-Z20P enables you to
increase the SNC-Z20P storage capacity for pre/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™ media card with a
Memory Stick/PC card adaptor can also be used.
Wireless Network Operation
The SNC-Z20P is compatible with an IEEE 802.11b-compliant wireless
PC card allowing wireless network operation
5
RS-232C Interface (Transparency Function or VISCA™ Protocol)
The SNC-Z20P has a transparency function available via the RS-232C
interface. This allows external equipment connected to the RS-232C port
of the camera to be controlled from a PC over the network. Also, the SNC-
Z20P can be controlled with the VISCA protocol from an external control
device, allowing local control of zoom and camera settings.
Analogue Composite Video Output
The SNC-Z20P can output an analogue composite video signal from a
BNC connector located on its rear panel. This allows recor<ding or mon-
itoring of the local image by connecting video equipment such as time-
lapse recorders, hard disk recorders, multiplexers, and video monitors.
