The 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 wall-
mounted or rack-mounted. These powerful and flexible
devices represent the cutting edge of high-performance
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 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.
MPEG‑4 4 inputs 2 inputs 1 input
4CIF 12.5/15 ips 25/30 ips 25/30 ips
2/3 D1 25/30 ips 25/30 ips 25/30 ips
2CIF 25/30 ips 25/30 ips 25/30 ips
ips = frame rate in images per second
H.264 4 inputs 2 inputs 1 input
2CIF 12.5/15 ips 25/30 ips 25/30 ips
ips = frame rate in images per second
