1. video files can choose to preserve video disk, in addition to the system tray, can be video, video is video disk file directory under "RecData" directory.

2. log files stored in the installation directory under "LogDb" directory.

3. the company LOGO stored in the installation directory under "Oem" directory, users can be added according to their own needs their company LOGO only need to amend

"CompanyLogoBk.bmp", "LogoBk.jpg" two pictures, then replace " CompanyLogo.bmp "," Logo.jpg "two picture on it.

1.3. Application Environment

The configuration of the system requirements are as follows:

Hardware

CPU: P4 1.7GHz and above Memory: 256 MB and above

Cards: 64 MB of memory Geforce 4 and above

Software

Disk Space

In order to ensure the normal operation of video, hard drive space shall not be less than 80 G.

1.4. Relevant technical characteristics and feature

Efficient use of the software in C + + and VCL advanced a combination of all of the OOA / OOD design concept.

 efficient use of cross-platform XML parser.

 use the thread pool technology, greatly reduces system resource overhead.

 the use of advanced Copy-On-Write technology, reducing redundant memory overhead.  use of mainframe and client-use completion ports, reduce data transceiver, in connection with

the delay time, all data and commands to adopt a port, the elimination of the multi-network DVR to bring out The routers do not use mapping port bottlenecks.

 use memory pool technology and reduce the frequency distribution of the memory system overhead.

 multithreading mutex adopted advanced literacy recursive locks, compared with the traditional Windows Lock Yong higher performance.

 use STL, Template, Template Meta-Programme, will run the system that compile-time expenses, the savings in operating system overhead, a reduction of the code, and increase the flexibility of the program, with more use of safeguard.

(5)

 extensive use of the universally recognized " Design Patterns", such as: Abstract Factory, Builder, Singleton, Composite, Command, Iterator, Proxy, very conducive to software development.

 more use of binary tree, hash algorithm, making access and faster processing.

 use exception handling mechanism, even if the board is due sdk or applications in a very specific situation, the same procedures can be achieved in the context of abnormal machine and the hardware / software environment to facilitate later revision.

 will use skin and functional separation xml and procedures to facilitate rejuvenate.

 accordance with the functions of software modules to facilitate the modification and maintenance.

 a self-extracting RAR installation forms to facilitate the replacement of LOGO and company information.

 each channel the same time only one video file, saving disk space.
