The NWD-455 FlexiDome IP is a high-performance, 1/3-
inch CCD 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, a BOSCH Video over IP (BVIP) decoder can
decode the stream for viewing on a CVBS or VGA monitor.
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, since these cameras no
longer require AC power.

Functions
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.
ONVIF
ONVIF (Open Network video Interface Forum) compliancy
ensures integration with third party management systems
and video network devices.
Intelligence
The FlexiDome 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.
Tri-streaming video
FlexiDome IP cameras can generate two separate H.264/
MPEG-4 video streams and one JPEG stream
simultaneously, while giving access to five users at a time.
This advanced tri-streaming capability, not typically found
in other IP CCTV systems, enables the user to optimize
live viewing and recording requirements to meet specific
site and enterprise needs. For example, BOSCH Video
over IP Systems (BVIP) can be configured to record video
at one quality setting (e.g. 3.75 IPS at 2CIF), while
simultaneously providing live images at the best possible
image quality (e.g. 30 IPS at 4CIF). Alternatively, the
system deliver a high bandwidth, H.264/MPEG-4 stream to
a local LAN user, while simultaneously streaming a low
bandwidth H.264/MPEG-4 stream to a remote user over a
WAN connection, while using the JPEG stream for remote
viewing, for instance, on a PDA.
