u High-quality MPEG‑4 video over IP

u H.264 Baseline Profile encoding

u Units with one, two, or four video inputs

Bosch VideoJet X SN encoders belong to a family of
high-performance, single-, dual-, or quad-input CCTV
video encoders that feature DVD-like quality MPEG‑4
video, at up to 25/30 images per second, over IP
networks. The units support PAL and NTSC sources
and provide bidirectional audio communication in
parallel to video. They are built into a housing that can
be easily rack-mounted. These powerful and flexible
devices represent the cutting edge of high­performance Video-over-IP for CCTV today.

Functions

Flexibility

VideoJet X SN encoders offer unparalleled recording
flexibility. Stream video across the network and store
it using Network Video Recorders (NVRs). Record
locally on CompactFlash, an external USB hard drive,
or network-attached RAID iSCSI storage devices. The
built-in iSCSI support enables the VideoJet X SN
encoders to act as conventional DVRs while streaming
high-performance live video across the network.

Dual Streaming

The VideoJet X SN encoders use Dual Streaming to
generate two independent IP video streams per
channel if sufficient computational power is available.
This allows viewing and recording at two different

u Network-attached RAID storage via iSCSI

quality levels to save disk space and bandwidth. On
alarm, they can send an e‑mail with JPEG images
attached.

Dual Recording

You can record the streams independently on different
media. Thus video can be recorded centrally on iSCSI
drives managed by VRM Video Recording Manager and
redundantly on the local media. If necessary, for
example in case of a network failure VRM can fill up
the gap in the central recording (ANR, Automatic
Network Replenishment).

Recording Profiles

The encoders feature a highly flexible recording
scheduler, providing up to ten programmable
recording profiles and allowing individually assigned
camera profiles. With these profiles, you can
accelerate the frame rate as well as increase the
resolution on alarm, saving recording space during
non-alarm periods.

H.264 Baseline Profile Encoding

Firmware 4.0 enables the Bosch VideoJet X encoders
to use H.264 Baseline Profile to encode the video
signal. This allows reducing the required bit rate for a
given quality setting, or increasing the quality when
keeping the bit rate setting.

Frame Rates and Resolution

When one or two inputs are used, the encoders deliver
MPEG‑4 video over IP at a full frame rate of 25 (PAL)
or 30 (NTSC) images per second with up to 4CIF
resolution on every channel. If four inputs are used,
the maximum frame rate is 12.5/15 images per second
at 4CIF resolution and no Dual Streaming is possible.
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 the double performance in respect
to MPEG‑4. Frame rate values must therefore be
divided by two.
The maximum frame rates listed in the tables below
depend on the resolution, picture content and
movement, and the number of inputs used.

Access Security

The VideoJet X SN encoders offer various security
levels for accessing the network, the unit, and the data
channels. As well as password protection with three
levels, they support 802.1x authentication using a
RADIUS server for identification. You can secure Web
browser access by HTTPS using a SSL certificate that
is stored in the unit. For total data protection, each
communication channel—video, audio, or serial I/O—
can be independently AES encrypted with 128‑bit
keys, once the Encryption Site License has been
applied.

Intelligence

With built-in video content analysis, VideoJet X SN
encoders reinforce the Intelligence-at-the-Edge
concept where edge devices become increasingly
intelligent. The VideoJet X SN comes with built-in
MOTION+ video motion detection. This motion
detection algorithm is based on pixel change and
includes object size filtering capabilities and
sophisticated tamper detection capabilities.
Bosch offers more advanced video content analysis
(VCA) applications with its Intelligent Video Analysis
(IVA). A licensable option, it bases the IVA algorithm
on digital imaging technology that uses multi-level
image analysis of pixel, texture, and motion
(trajectory) changes.

Viewing

View the VideoJet X SN encoder video on a PC using a
Web browser, in the Bosch Video Management
System, or integrate it into another video management
system. By routing the IP video to a high-performance
VIP XD video decoder or a VIDOS Monitor Wall, you
can present the video with ultimate clarity.

Camera control

Configure and control your camera or dome using one
of the various pre-defined control protocols.
VideoJet X SN encoders provide a serial interface and
alternatively support Bilinx communication over coax
cable.

Easy Upgrade

Remotely upgrade the VideoJet X SN encoders
whenever new firmware becomes available. This
ensures up-to-date products, thus protecting
investment with little effort.

ONVIF conformance

Firmware 4.10 introduces conformance to the ONVIF
(Open Network Video Interface Forum) specification
guaranteeing interoperability between network video
products regardless of manufacturer. ONVIF
conformant devices are able to exchange live video,
audio, metadata and control information and ensure
that they are automatically discovered and connected
to network applications such as video management
systems.
