The Digital Eyewitness ION Eclipse features an open architecture design that allows maximum flexibility to customize the system and upgrade with future technology. The DEW ION Eclipse includes three compression schemes: MPEG1, MPEG2 and MPEG4, with a choice of recording rates for each. The compression is user selectable and can be changed even after the system is installed. The ION Eclipse offers hard drive (HDD), DVD-RAM and Compact Flash file storage options and manual, hard-wired and wireless file transfer options. Different controller/monitor configurations include an integrated overhead console with monitor; separately mounted monitor and controller; or a mobile computer as the system's controller/monitor. The ION Eclipse includes up to three minutes of pre-event recording. Options include ClearComm DSS (a 900 MHz Digital Spread Spectrum wireless audio system), crash record activation and GPS.
