Detailed Selling Lead Description
Technical Guidelines: Parameters of video Video input: PAL, NTSC 8 channel composite video input(BNC port, 1VP-P, 75ohm) Video output: PAL, NTSC A composite video output(BNC port, 1VP-P, 7575ohm) A VGA output(frequency: 60-85HZ, resolution ratio: 480*320-1024*768) Parameters of audio Audio input: 4 channel audio input(lotus, 20-100mv, 10K75ohm) Audio output: An audio output(lotus, 20-100mv, 1K75ohm) Compression arithmetic: Video compression: H. 264; Audio compression: G. 729 Image resolution ratio: Real-time display(704*576), Video compression CIF (352*288) Audio sampling ratio: 8K sampling point per second, 16 bit per sampling point The quality of the record: There are 12 in all, from high to low Operating system: Embedded real-time operating system (RTOS) Network port: Adaptive Ethernet port of 10M/100M HDD: Support 8 parallel IDE & 2 SATA Series port: RS485 Backup: SATA, Network Power supply: 220+-30% V, 50+-3% HZ Working temperature: -10 to 55 Working humidity: 10%--90% Power consumption (without hard disk): 25W Dimension: Width 440mm, depth 435mm, height 96.6mm Main functions: VG-858CF series embedded digital video recorder adopt high performance criterion of embedded real-time multiple operating system (RTOS) and embedded processor to set up a monitor system perfectly. All the codes are embedded in FLASH that the system is steadier and will not be interfered by external factors such as virus etc. It also can work steadily for a long time under abominable environment and under the situation with no guard. Compress Function 1. Support PAL/NTSC4.43/NTSC3.58 video signals 2. The video compression is H. 264, supports VBR as well as CBR 3. Can set up video picture quality and compression yard 4. Separatedly compress each audio and video signal stream, the compressed audio standard adopts G. 722, the sampled point is: 8K sampled point per second, 16bit per sampled point 5. Compound H264 is produced after compressing video and audio signals, the video and audio keep moving simultaneously and can set up no audio record when playback 6. CIF: There is low definition available 7. 6 kinds of record image quality for choosing, users can select video quality according to the special need, so as to ensure for enough long video time.
