Bosch VideoJet X20 SN Video Encoder with 2 Video Input
Bosch VideoJet X SN encoders belong to a family of highperformance, 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 rackmounted. These powerful and flexible devices represent the cutting edge of high-performance Video-over-IP for CCTV today.FunctionsFlexibilityVideoJet 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 networkattached 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 StreamingThe 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 RecordingYou 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 ProfilesThe 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 EncodingFirmware 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 ResolutionWhen 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.Access SecurityThe 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.IntelligenceWith 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.ViewingView 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 controlConfigure 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 UpgradeRemotely upgrade the VideoJet X SN encoders whenever new firmware becomes available. This ensures up-to-date products, thus protecting investment with little effort.ONVIF conformanceFirmware 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.
