Easy Mounting and Flexible
Installation
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.
MPEG-4 and JPEG Compression
Formats
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
standard JPEG compression format is selectable
from the setup menu. The SNC-DF Series also
supports variable bit rates up to 2Mb/s.
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.
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.

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
