Bosch VideoJet X20/X40 XF E H.264 Video Encoder

X20/X40 XF E  Key Features


High-quality H.264 video over IPv4 and IPv6
Bandwidth-friendly adaptive bit rate encoding
Transcoding at the edge for advanced remote replay
Network-attached RAID storage via iSCSI
Local recording on CF card

X20/X40 XF E Description

Bosch VideoJet X20/X40 XF E encoders belong to a family of high-performance, dual- or quad-input CCTV video encoders that deliver real-time H.264 compressed video over IPv4 and IPv6 networks. The units provide two independent streams per camera with full frame rate at best quality for different purposes, like one stream for live viewing with lowest delay while the second stream is optimized for requiring only little recording space. VideoJet X20/X40 XF E encoders 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- or wall-mounted. These powerful and flexible devices represent the cutting edge of high-performance Video-over-IP for CCTV today.

X20/X40 XF E Functions


VideoJet X20/X40 XF E encoders offer unparalleled recording flexibility. Stream video across the network and store it using Network Video Recorders (NVRs). Record locally on Compact Flash, or network-attached RAID iSCSI storage devices. The built-in iSCSI support enables the VideoJet X20/X40 XF E encoders to act as conventional DVRs while streaming high-performance live video across the network.

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.


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.

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 Main Profile and Baseline Profile encoding Bosch VideoJet X20/X40 XF E encoders use H.264 Main Profile and Baseline Profile to encode the video signal. H.264 Main Profile allows encoding with the best encoding and compression efficiency while H.264 Baseline Profile maintains backward compatibility to less-advanced decoders.

Frame rates and resolution

The VideoJet X20/X40 XF E encoders provide dedicated hardware for encoding and thus are not limited in frame rate and resolution settings, nor in Dual Streaming.

Access security

The VideoJet X20/X40 XF E 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.


VideoJet X20/X40 XF E comes with built-in MOTION+ video motion detection. This motion detection algorithm is based on pixel change and includes object size filtering capabilities and sensitivity settings.

Camera control

Configure and control your camera or dome using one of the various pre-defined control protocols. VideoJet X20/X40 XF E encoders provide a serial interface.

Easy upgrade

Remotely upgrade the VideoJet X20/X40 XF E encoders whenever new firmware becomes available. This ensures up-to-date products, thus protecting investment with little effort.

ONVIF conformance

Firmware 5.50 introduces conformance to ONVIF 1.02 and ONVIF Profile S, providing interoperability between network video products regardless of manufacturer. In addition, Firmware 5.50 supports all applicable features of the ONVIF 2.2 specification. 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.
