The NWD-495 FlexiDome
DN
IP is a high-performance 1/3-
inch CCD Day/Night network camera, designed to ensure
the highest possible image quality at all times. This ultra-
compact and vandal-resistant camera provides DVD-like
quality MPEG-4 video at up to 25 and 30 images per
second (for PAL and NTSC respectively) or H.264
encoding. Network video signals are sent over IP networks
and can be received and displayed on a PC web browser,
viewed and recorded using the DiBos hybrid recording
system, or managed as part of a VIDOS or BVMS video
management system. Moreover, send the stream to a
BOSCH Video over IP (BVIP) decoder for viewing on a
CVBS or VGA monitor.
The camera combines 15-bit digital video processing
(which enhances sensitivity) and XF-Dynamic (which
extends the dynamic range) to provide a sharper, more
detailed image with outstanding accuracy in color
reproduction. Depending on the available light, the
NWD-495 automatically switches from color to
monochrome, enhancing sensitivity for IR illumination to
provide high-quality images even in challenging low-light
conditions.
FlexiDome IP uses H.264 or MPEG-4 compression,
bandwidth throttling, and multicasting capabilities to
manage bandwidth and storage requirements efficiently
while delivering the best image quality and resolution. The
analog video service output and the on-screen displays
(OSD) simplify focus adjustment and network
configuration, leading to lower installation and support
costs. Power over Ethernet (PoE) makes installation
easier and more cost-effective because cameras no longer
need AC power
Functions
Day/Night Mode
In Night Mode, the NWD-495 provides enhanced night
viewing by increasing the IR sensitivity. The IR filter can
switch automatically from color to monochrome by
sensing the illumination level or be remotely switched via
a web browser. An internal, through-the-lens IR detector
enhances monochrome mode stability by preventing the
camera from returning to the color mode when IR
illumination is dominant.
XF-Dynamic
The highly accurate 15-bit digital signal is automatically
processed to reveal every detail of the image in both the
highlight and low-light areas of the scene simultaneously.
Intelligence
The FlexiDome Day/Night IP supports increased
intelligence at the edge that provides powerful tamper
detection for various combined picture cases arising from:
video loss, masking, hooding, defocusing, and diverted
camera. Bosch also offers Intelligent Video Motion
Detection (IVMD) as an additional licensable option. This
provides video content analysis (VCA) directly at the video
input for even more advanced VCA.
H.264 Baseline Profile Encoding
Firmware version 4.0 and higher enables the camera to
use H.264 Baseline Profile to encode the video signal. This
reduces the required bit rate for a given quality setting, or
increases the quality while keeping the bit rate setting.
Because H.264 Baseline Profile does not support field
encoding, interlaced video is not possible, thus resolution
is limited to a maximum of 2CIF. H.264 encoding requires
double the performance in respect to MPEG‑4. Frame rate
values must therefore be divided by two.
MPEG-4 Video Encoding
The FlexiDome MPEG-4 encoder creates high-quality
streaming video at low bit rates, minimizing bandwidth
and storage requirements, which further reduces costs.
Each FlexiDome IP camera can deliver up to 25 and 30
images per second (PAL and NTSC) at true 4CIF video
resolution.
