3.3 Overview of functions
Network video server
The VideoJet XF E is a compact network video server for two (VideoJet X20 XF E) or four
(VideoJet X40 XF E) connected video sources. It is primarily designed for encoding video,
audio and control data for transfer over an IP network. With its encoding in the H.264 format,
the VideoJet XF E is ideally suited for making existing analog CCTV cameras IP-compatible and
for remote access to digital VCRs and multiplexers.
The use of existing networks means that integration with CCTV systems or local networks can
be achieved quickly and easily.
Two units, for example a VideoJet XF E as a sender and a VIP XD HD as a receiver, can create
a standalone system for data transfer without a PC. Video images from a single sender can be
received simultaneously on multiple receivers. Audio signals can also be transmitted from and
to compatible units.
Triple Streaming
The VideoJet X20/X40 XF E encoders use Dual Streaming to generate two independent
IP video streams per channel. This allows viewing and recording at two different quality levels
to save disk space and bandwidth. As a third stream for easier third-party integration they
provide an independently configured M-JPEG stream. On alarm, they can send an e-mail with
JPEG images attached.
Video encoding
The VideoJet XF E uses the H.264 video compression standard. Thanks to efficient encoding,
the data rate remains low even with high image quality and can also be adapted to local
conditions within wide limits.
Audio encoding
The VideoJet XF E uses the G.711 and L16 audio compression standards. G.711 is the default
setting both for live transmission and recording. When configuring with a Web browser, you
can select L16 for recording. Using video management systems, L16 is also available for live
audio.
Viewing
View the VideoJet X20/X40 XF E 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 HD video decoder you can present the video with
ultimate clarity. Adaptive bit rate encoding enables viewing from remote sites over bandwidth-
limited connections and wireless connections to mobile clients. Latest HTML5 technologies
provide easy access from Android, Windows Phone and iOS based mobile devices.
Region of interest (ROI)
Get every detail even on lower bandwidth or smaller video window by panning, tilting and
zooming a region-of-interest cut-out from the full image. ROI is possible on both live viewing
and playback of recordings.
Advanced remote playback
Bosch’s latest enhancements—adaptive bit rate encoding and transcoding—allow replay of
recordings over bandwidth-limited connections with smooth browsing through the footage
while not missing any detail. Be it a remote guard searching for a specific evidence or alerted
by alarm notification, quick access to the relevant recording is easily achieved, and recorded
images are presented in original quality even over weak links.
