MPEG-4 and JPEG Compression
Formats
Easy Mounting and Flexible
Installation
The SNC-DF Series supports both the MPEG-4
and JPEG compression formats. The high
compression ratio of MPEG-4 provides smooth
moving images over networks even when
bandwidth is limited. If higher quality still
images are preferred, then the industry
The SNC-DF Series can be wall-mounted or
ceiling-mounted with the supplied ceiling-
mount bracket. What's more, the 2.7x vari-
focal lens incorporated into these cameras can
be freely rotated, allowing for easy adjustment
of the camera's viewing angle after installation.
standard JPEG compression format is selectable
from the setup menu. The SNC-DF Series also
supports variable bit rates up to 2Mb/s.
a (Panning): 150°
b (Tilting): 75°
Image size can be selected from six modes:
640 x 480, 480 x 360, 384 x 288, 320 x 240,
256 x 192, and 160 x 120.
c (Rotating): 150°
High Frame Rate
The SNC-DF Series produces images at a
maximum frame rate of 30fps (NTSC) /25fps
(PAL)*3 when the image size is 320 x 240 in
both MPEG-4 and JPEG modes, producing clear
and smooth-moving images.

In order to view images at the maximum frame rate,
adequate PC processing power and network bandwidth
are required.
Audio Monitoring
Incorporating an external microphone input,
the SNC-DF Series is capable of picking up
sound from camera site clearly. The unit is also
equipped with an audio line output for active
speakers; allowing users to communicate with
the remote site, expanding the capability of
remote monitoring applications.
Ceiling Surface Mount (SNC-DF40)
Day/Night Function (SNC-DF70)
The SNC-DF70 features a "Day/Night"
capability, which provides optimized sensitivity in
both day and night shooting applications.
As the scene darkens, an infrared filter is
automatically replaced with a clear filter and the
camera switches to B&W mode, allowing for
operation at a minimum illumination of 0.2 lx at
F1.0, or 0 lx*4 using an IR Illuminator from 3rd
party vendors*5.
*4
0 lux means absence of visible light to the naked eye.
Please contact your local Sony dealers for 3rd-party item.
Ceiling Flush Mount (SNC-DF40)
*Optional YT-ICB40 Ceiling-mount bracket is required.

Ruggedized Design (SNC-DF70)
Alarm Functions
The SNC-DF70 is specially designed to be used
for outdoor surveillance or indoors for vandal
resistant applications. The cameras are housed
in a heavy-duty aluminum die cast enclosure
with a durable polycarbonate viewing window.
These cameras comply with the IP66*6 standard
for protection against water and dust.
Motion Detection/Alarm Trigger
The SNC-DF Series 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 to detect motion so that unwanted
noise components do not accidentally trigger
the alarm. In addition to these features, the
SNC-DF Series is equipped with a sensor-input
port that can receive a trigger from an external
sensor.
*6
Ingress Protection (IP) standard is a system for numerically
classifying the degree of protection provided by
enclosures of electrical equipment against solid objects
and liquids. IP66 means there is no ingress of dust and
the equipment is protected against powerful water jets.
Network Features
Pre-/Post-Alarm Image Storage
Adaptive Rate Control
With a built-in buffer memory, the SNC-DF
Series can store several seconds of pre-alarm
and post-alarm still images when an alarm is
triggered by the motion detection function, the
alarm input, or both.
To meet Quality of Service (QoS) requirements
over a network, the SNC-DF Series provides an
adaptive rate control function. This function
automatically varies the bit rate of audio and
video data to meet changing network
conditions and selects the most appropriate
frame rates. This function helps prevent audio
and video breakup.
Image storage capacity
MPEG 4 image: Approx. 15 s* (pre-/post- 7.5 s)
*when the image size is 320 x 240 at a frame rate of
30fps and a bit rate of 512 kbps
JPEG image:
*when the image size is 320 x 240 at a frame rate of
15fps and the image quality is set to Level 3
Approx. 10 s* (pre-/post- 5 s)
Multicasting Capability
The SNC-DF Series has a built-in multicasting
capability that enables efficient video and audio
streaming to a large number of users.
Image Transfer Using FTP/SMTP
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, the still
image captured at the time of an alarm event
can be sent to a designated e-mail address.
Simultaneous Access
Up to 20 (JPEG mode)/10 (MPEG-4 mode) users
can simultaneously access any of the SNC-DF
Series cameras and monitor images separately.
Analog Composite Video Output
Network Security Features
Access to the SNC-DF Series 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.
In addition, user names and passwords can be
assigned to allow three levels of access.
The administrator has complete access/control
of the cameras; while the other two levels of
access can be set to limit user privileges to
functions such as viewing, trigger control, etc.
The SNC-DF Series is equipped with an analog
composite video output, allowing camera
images to be directly recorded or monitored by
connecting video equipment such as time-lapse
recorders, hard disk recorders, and monitors.
