Digital Video Server With Storage And WiFi The Digital Video Server is an embedded surveillance device specially designed for network application.It’s used the newest technics and high integration single chip SOC with powerful linux RTOS (Real-time Operating System) realize high performance and low cost digital mutimedia process. Built-in (ARM9+DSP) and high speed video frequency processor, realizes the code, network transport and video record in a body's media processing, had guaranteed system's high integration rate, the redundant reliability and the high stability to actually realize industry level MTBF (Mean Time Between Failure).Optimized H.264 video compression algorithm assures image transmission clearer and more fluent. Support IDE, USB, the SD card interface, convenient user realizes the video storage and the data backup; Built-in Web Server allows user to carry out remote control via Internet Explorer conveniently.Furthermore, central management software can be used for integrated surveillance and management of multiple video servers, so that build up large and multilevel video surveillance system.| Model | NVS901D /NVS902D / NVS904C | NVS901WD /NVS902WD / NVS904WC | | Video Input | 1、2、4channel composite video, PAL/NTSC ，BNC (1.0Vp-p, 75Ω) | | Video Compression | H.264 Baseline Profile@Level 2.2 | | Video Definition | PAL：352*288（CIF），704*288（2CIF），704*576（D1）；
