Bi-Directional Audio
The SNC-RZ25P supports both ITU-T G.711 and G.726 audio
compression standards. Equipped with a microphone input,
the SNC-RZ25P can be configured with a microphone so that
audio, including sound from distant objects, can be monitored
at the camera site. The unit is also equipped with an audio line
output for active speakers. Using these speakers, users can
send an alert or make an announcement, significantly
expanding the possibilities for remote monitoring
applications.
Alarm Functions
Motion Detection/Alarm Trigger
The SNC-RZ25P 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-RZ25P is
equipped with a sensor-input port that can receive a trigger
from an external sensor.
Pre-/Post-Alarm Image Storage
With its built-in buffer memory, the SNC-RZ25P 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 25 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*
3
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. A still image at the time of an alarm event can also be
sent to a designated e-mail address.
*3 All transferred images are in JPEG format. MPEG images are
converted to JPEG before being transferred.
All-In-One PTZ Network Camera
The SNC-RZ25P is equipped with a 100Base-TX/10Base-T
network interface and a built-in web server, allowing you to
configure the unit in any TCP/IP network. To run the unit, all
that is needed is a PC running a web browser*
1
and a network
environment; no additional software is required. The SNC-RZ25P
is PTZ-capable with a pan range of 340°, a tilt range of 120°,
plus an 18x optical zoom capability.

98 or higher operating system and
Microsoft Internet Explorer 5.5 or higher web browser.
High-Quality Images
Employing a 1/4-type ExwaveHAD CCD, the SNC-RZ25P
delivers exceptional picture quality for your remote monitoring
applications. Furthermore, because the minimum illumination
level is 0.7 lx at F 1.4, the SNC-RZ25P operates extremely
well even in low-light conditions.
'Day/Night' Function
The SNC-RZ25P offers a 'Day/Night' function to provide
optimised sensitivity in both day and night environments. As
the scene darkens, the infrared cut-filter is automatically
replaced with a clear filter and the camera switches to B/W
mode, requiring a minimum illumination of less than 0.01 lx.
Three modes can be set: automatic, manual, or a timer mode.
Selectable MPEG-4 or JPEG
Compression Formats
The SNC-RZ25P uses the MPEG-4 compression format to
achieve high-compression ratios without sacrificing image
quality. MPEG-4 allows smooth moving images to be
streamed over a wide range of bandwidths so users can
monitor high-quality moving images with minimal delay —
even over limited bandwidths. The SNC-RZ25P supports
variable bit rates up to 2 Mb/s.
Transmission protocols (TCP or UDP) and image size can be
selected to meet your network environment and application
requirements. The following image sizes are selectable:
640 x 480, 480 x 360, 384 x 288, 320 x 240, 256 x 192, and 160 x 120.
If higher quality still images are preferred, then the industry-
standard JPEG compression format can be selected from the
setup menu.
High Frame Rate
The SNC-RZ25P produces images at a maximum frame rate
of 25 fps*
2
when the image size is 320 x 240 in both MPEG-4
and JPEG modes, producing clear and smooth-moving
images. The frame rate can be fixed or set to a variable rate
that automatically adjusts to the available bandwidth.
*2 In order to view images at the maximum frame rate, adequate PC processing
power and network bandwidth are required.
