Network Features
Adaptive Rate Control
In order to control QoS (Quality of Service) levels over a
network, the SNC-RZ25 employs an adaptive rate
control function. This function automatically varies the
video bit-transfer rate to meet changing network
conditions. Adaptive rate control also selects the most
appropriate frame rates, preventing audio and video
breakup.
Simultaneous Access
Up to 20 users in JPEG mode or 10 users in MPEG-4
mode can simultaneously access the SNC-RZ25 and
monitor images separately.
Multicasting Capability
The SNC-RZ25 has a built-in multicasting capability.
When configured with a multicast router, the unit
can efficiently stream video and audio to a large
number of users.
Compact Flash™ (CF) Type Card
Slot/Wireless Capability
A built-in expansion slot for Compact Flash cards is
integrated into the SNC-RZ25, enabling you to store
additional images on CF media as required.
You can also opt to install the SNC-RZ25 in a
wireless network to avoid unsightly wires, as the CF
type card slot can accept the optional SNCA-CFW1
Wireless Card. This wireless card is IEEE 802.11b
compliant.
Alarm Functions
Motion Detection
*4
/Alarm Trigger
The SNC-RZ25 is equipped with a built-in motion
detection function that can generate an alarm through
its alarm-output port or trigger another device to
perform a variety of actions. The motion-detection
function uses vector information so that unwanted
noise components do not accidentally trigger the
alarm. In addition to these features, the SNC-RZ25 is
equipped with a sensor-input port that can receive a
trigger from an external sensor.
*4
The motion detection function is available only with
MPEG-4 compression.
Pre-/Post-Alarm Image Storage
With its built-in buffer memory, the SNC-RZ25 can
store several seconds of pre-alarm and post-alarm
images when the motion detector, the sensor input,
or both trigger an alarm.
Maximum Image Storage Capacity
(Definable from the Setup Menu)
MPEG-4 Compressed Images: Approx. 30
seconds
*
(pre-/post- 15 sec)
.
*
when image size is 320 x 240 at 30 fps and 512 kbps
JPEG Compressed Images: Approx. 10 seconds
*
(pre-/post- 5 sec).
*
when image size is 320 x 240 at 15 fps and image
quality is set to Level 3
Image transfer using FTP/SMTP
*5
All of the pre-/post-alarm images stored at the time of
an alarm event can be transferred to an FTP server for
later viewing. Also, a still image at the time of an alarm
event can be sent to a designated e-mail address.
*5
All images transferred using SMTP are in JPEG format.
Network Security Features
IP Filtering
With IP filtering, access to the SNC-RZ25 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.
Password Protection
User names and passwords can be assigned to allow four
levels of access. The administrator has complete
access/control of the cameras; while the other three levels
of access can be set to limit user privileges to functions
such as PTZ control, viewing, and trigger control.
Analog Composite Video Output
The SNC-RZ25 can output an analog composite
video signal via the BNC connector on the unit's rear
panel.
*6
This feature is ideal for sending signals to a
local recording device or monitor.
*6
The SNC-RZ25N output is in NTSC format (525/60), and
the SNC-RZ25P output is in PAL format (625/50).
