| Application Fields
4008CS series is a kind of new generation embedded DVR produced by our company. Nowadays, video surveillance technology is developing rapidly for the aim of digital, connected and intellectualized. The core technologies--compression algorithm, network technology, intellectualized technology and etc. are all integrated in DVR. Therefore, audio and video codec card, embedded DVR and DVS are absolutely the core components of digital video surveillance system. As the Chinese business is developing at a very high speed, DVR and DVS have already been widely used in finance, electric power, posts, government, military, public security, transportation, irrigation works, prison, market place, hotel, wharf, station and many other fields and places in last 10 years.
Application Mode
The true integrated security system can be developed within hardware platform based on embedded DVR and central controlled software platform. The integrated security system, as a word, is a system which integrates security hardware just like monitors, guards, burglar alarm, voice communication based on the definition of soft equipments for a coordinated control. Surveillance system like that integrates graphic monitor, burglar alarm, one card management, patrol management, boundary surveillance, building facilities monitor, digital map and etc., which can also provides surveillance interface design and source distributed service for system integrators.
Characteristics Instruction
8-channel CIF pre-real-time hardware encoding card adopting PHILIPS earlier 13XX DSP as the coding chip processor, fits for scenes with few or stable moving such as the digital surveillance of offices and passages.
High stability, preview with little system resource, lower than 5% for simultaneous 16-channel recording, recommended maximum channel number is 32 in ordinary commercial computers and 64 for business computers. It fits for Windows2000/XP/LINUX operating platform, and it can be compatible with all kinds of main boards and display card.
Rich functions, real-time audio and video streaming compression, optional coding frame format, image quality, code rate and video parameters of video signal; motion detection, object detection, OSD, LOGO and partial shelter are supported.
8-channel video and 2 channel audio are supported in the encoding card, of which channel 1 and 5 support live monitoring.
