What is the Advantage of PC-based Disk Video Recorder (DVR)

• PC-based disk video recorder (DVR) offers several advantages:
  A larger storage space (easily extended storage hard drive), suitable for a long video, local storage stability.
  Good interface and document management, through the mouse, keyboard, as long as the person used a computer can operate it well;
  Hardware and software upgrades easier, product updates more faster.
  Maintenance costs are low; the general failure could be repaired through replace parts.
  Hardware and software design of embedded systems are usually more difficult, but it provides the user with the following benefits:

  Easy to use, don’t need PC operating skills; as long as the user used DVD / VCD, he could use embedded DVR, do not need to learn how to move the mouse, double-click the computer mouse and other complex operation.
  High stability of the system, software fault tolerance better, don’t need people to manage it. Embedded DVR with embedded real-time multi-tasking operating systems, video surveillance, compression, storage, network transmission and other functions concentrated in a smaller device, the system’s real-time, stability, reliability greatly improved, suitable for unattended environment;

  Software solidified in the FLASH / EPROM, non-modified and high reliability. PCDVR software is generally installed on the hard disk, the system abnormal shutdown could cause the system files are damaged or the system hard disk is damaged, causing the collapse of the entire system, reliability is poor. Embedded DVR software solidified in the FLASH / EPROM, no system files are damaged and the hard disk may be damaged, reliability is high.
  The system used embedded real-time operating system boot fast. PCDVR using desktop operating system, Windows, Linux, etc., required a longer time. Embedded DVR use the embedded real-time operating system, which can be cut, just need a few seconds.
  Hardware and software are low cost. Embedded DVR with integrated hardware architecture, not need to buy graphics card, memory, and other equipment as PCDVR, hardware cost less than PCDVR.
  The software uses proprietary embedded operating system; users do not need to pay for the part of the costs (equipment suppliers, the part of the costs included in development costs).
  Embedded DVR have small size, simple and compact structure. Embedded DVR hardware using integrated design, unlike PCDVR structure; the whole system structures is simple, small size, light weight, but also improve system stability and reliability.
