High-Quality Images
High Frame Rate
T
hese cameras support a maximum frame rate of 30
f
ps (NTSC)/25 fps (PAL) when the image size is VGA
(
640 x 480) in both MPEG-4 and JPEG modes, resulting
i
n clear and smooth-moving images. The frame rate
c
an be set to meet your specific network
e
nvironment and system requirements.
Dynamic Frame Integration
These cameras incorporate Dynamic Frame Integration
(DFI) technology to reproduce clear images for both
s
till and moving objects within an image.
D
FI technology detects movement within the image
a
nd reproduces those areas with minimal blurring,
w
hile areas in the image with little or no movement
a
re displayed naturally with minimal jagged edges.
T
his unique algorithm also takes advantage of the
i
nterlaced-scanning CCD,which is inherently more
s
ensitive than progressive-scan CCDs and can provide
c
lear images even under low-lighting conditions.
JPEG Picture Quality Settings With
Constant Bitrate Algorithm
Users can preset the JPEG picture quality from among
ten levels. In addition,because these cameras
incorporate a constant bitrate algorithm, they limit
the data bitrate while maintaining high-quality
images. This is useful for calculating the required
storage capacity and bandwidth during installation.
Image Stabilizer
The image stabilizer function of these cameras minimizes
the appearance of shaky images caused by low-
frequency vibration to provide stable and sharp
images. This function is useful for outdoor surveillance
and traffic monitoring applications when environmental
vibration effects such as wind are common.

t
echnology,
w
hich dramatically improves camera dynamic range
by 128 times when compared to conventional
cameras. This results in clear image reproduction,
even in extreme high-contrast environments. The
camera captures the same image twice – first with a
normal shutter speed, and then with a high shutter
speed. The dark areas captured at normal shutter
speed and the bright areas captured at high shutter
s
peed are then combined into one image using an
a
dvanced DSP LSI. Additionally, as these high-
c
ontrast scenes may have different lighting
c
onditions, two white balance circuits are employed
o
ne for normal shutter speed and the other for high
s
hutter speed. This advanced technique reproduces
h
igh-contrast images with proper color.
Powerful and Versatile Zoom Capability
The SNC-RX570 incorporates a powerful 36x optical
zoom lens,allowing for a zoom capability of up to
432x when used in combination with its 12x digital
zoom. The SNC-RX550 and SNC-RZ50 incorporate a
26x optical zoom lens and the SNC-RX530 incorporates
an 18x optical zoom lens.
Users can choose a camera that has the appropriate
zoom ratio for their specific application requirements.
