High-Quality Images
High Frame Rate
These cameras support a maximum frame rate of 30
fps (NTSC)/25 fps (PAL) when the image size is VGA
(640 x 480) in both MPEG-4 and JPEG modes, resulting
in clear and smooth-moving images. The frame rate
can be set to meet your specific network
environment and system requirements.
Dynamic Frame Integration
These cameras incorporate Dynamic Frame Integration
(DFI) technology to reproduce clear images for both
still and moving objects within an image.
DFI technology detects movement within the image
and reproduces those areas with minimal blurring,
while areas in the image with little or no movement
are displayed naturally with minimal jagged edges.
This unique algorithm also takes advantage of the
interlaced-scanning CCD, which is inherently more
sensitive than progressive-scan CCDs and can provide
clear 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.

Wide Dynamic Range With DynaView
Technology
The SNC-RX570 incorporates DynaView ™ technology,
which 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
speed are then combined into one image using an
advanced DSP LSI. Additionally, as these high-
contrast scenes may have different lighting
conditions, two white balance circuits are employed –
one for normal shutter speed and the other for high
shutter speed. This advanced technique reproduces
high-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.
