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 Stick
TM
" 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 VISCA
TM
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.
