Full 16CH D1 Network DVR @Top advanced arithmetic: H. 264 (MPEG4 Part 10) video compression. Powerful chipset: Adopt Philip-Trimedia Chipset that has 16DSP. One DSP deal with one channel. @ High stability: Absolute Hardware compression and professional embedded operating system. @ Real time: 16ch video and audio synchronized display and record real time. @Perfect image: 9 grade image level from 128k to 4. 5M. It can satisfy with low bit rate for network transmission. And also for suitable bit rate for high image recording. @ Good network transmission: It can transmit on PSTN, ISDN, ADSL, WAN, LAN. @ Built-in 8 HDD: For industrial configuration. Don't pay any money on Disk Array. @ Individually working: Each channel compresses the signal at real-time individually, the parameters of resolution, frame, and record time can be set up separately. @ Support real watermark technology so that compressed image file can't be juggled.
