FEATURES
All-In-One PTZ Network Camera
The SNC-RZ25 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
*2
and a network
environment; no additional software is required. The
SNC-RZ25 is PTZ-capable with a pan range of 340°, a
tilt range of 120°, plus an 18x optical zoom
capability.

Pan/Tilt Range
High-Quality Images
Employing the latest 1/4-type Exwave HAD CCD, the
SNC-RZ25 delivers exceptional picture quality for your
remote monitoring applications. Also, because the
minimum illumination level is 0.7 lx at F 1.4, the
SNC-RZ25 operates extremely well even in low-light
conditions.
"Day/Night" Function
The SNC-RZ25 offers a "Day/Night" function to provide
optimized 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-RZ25 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 a minimal delay even over
limited bandwidths. The SNC-RZ25 also 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
30 degrees
selected from the setup menu.
High Frame Rate
90 degrees
The SNC-RZ25 produces images at a maximum frame
rate of 30fps
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.
340 degrees
In order to view images at the maximum frame rate,
*3
adequate PC processing power and network bandwidth
are required.
Bi-Directional Audio
The SNC-RZ25 supports both ITU-T G.711 and G.726
audio compression standards. Equipped with an
external microphone jack, the SNC-RZ25 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.
