Bosch Releases VideoJet Xpro

The new digital Bosch video transmission system VideoJet XPro is a virtual matrix network-based system for CCTV applications such as large-scale alarm systems or corporate TV. Compared to analog matrix systems, the VideoJet XPro boasts many advantages like, i.e. the high number of channels and video quality as well as signal recording over longer period of times. It also allows for remote control functions of cameras. These characteristics as well as the exceptional price/performance ratio make the system an economic alternative to an analog multiplexer with external digital video recorder.

The 7-HE cabinet housing in 19 inch technology offers sufficient space for a maximum of 20 VideoJet XPro cartridges, transmitting a total of up to 160 real-time video signals. The cartridges exist in three different versions: the V8 transmits either eight PAL or NTSC video channels, type VA8 offers eight additional full-duplex audio channels. The third type of cartridge provides two hard discs with 120 GByte storage capacity each for signal recording.

Each cartridge provides non-multiplexed MPEG-2 video streams simultaneously over Gigabit-Ethernet and ISDN interfaces. The datarate is sufficient for up to 480 frames per second in DVD quality with a maximum resolution of 720 x 576 pixels. The images can be viewed on commercially available standard PCs with web browsers, workstations with software decoders or monitors with MPEG-2 Bosch hardware decoders. It is possible to select any chosen camera for viewing on the monitor by remote control via network (LAN/WAN). In addition to live viewing of current events, VideoJet XPro archives the video stream on hard discs ' on site with the hard disc cartridge of the system as well as decentralized with network video recorders. By transmitting in multicast technology, several receivers may use the video stream simultaneously.

VideoJet XPro takes into account the differing requirements for live viewing on a monitor and recording of video images. It is thus possible to select for recording purposes a D1 resolution with just one frame per second which saves resources and to switch to real-time imaging of 25 frames per second for live viewing. The "dual streaming" of the virtual matrix system transmits both signals in parallel, which allows for freely selectable combinations as regards frame repetition rate.
