3. Data management and data are safe
Data of the protection in video supervisory system not because be mixed accidentally baleful destroy formerly consequently, change and be being shown is special necessary. The data that transmits through wireless network or Internet can suffer intercept very likely. This meeting brings huge risk to sensitive data. To the hacker on a few nets or baleful employee, the safe protection that goes up to data processing system is built and take technology and management is insufficient. To this, very be necessary to be adopted to data add secret technology.
Of industry of the increase that orders as monitoring, application increasingly the promotion of the extension of cycle of time of generalization, monitoring and video definition, video data capacity also is developing at full speed. Although store in order to compress a form according to certain level these data, till the data of on 1000 TB needs file, memory,still have 100 TB, and need high speed transmit. Be aimed at these circumstances, a reality that optimizing solution of video memory, file and equipment to choose had been a lot of users considers.
Generally speaking, from the point of applied demand, the system of the design must have the following demand: Safeguard is had long the ability of failure free operation; Can deliver high-definition clear picture remotely in real time, come true time put; Have the capacity of data of agile memory image, memory withholds time to achieve particular demand; Image is transmitted must have prevent filch function, image data is had prevent distort function; Equipment operation must have safe management and control medium.
3, be based on the wireless video supervisory system of different network
1. Be based on the wireless video supervisory system of public mobile network
China moves and Chinese UniCom already owned the 2.5G mobile network that spreads all over the whole nation severally. Can undertake on mobile phone of palmtop computer, PDA long-range video is collected with transmit, what only should the place of network signal can realize video is wireless transmit, realize mobile monitoring truly.
The product of is based on shift public network wireless video monitoring that a lot of companies rolled out him. Be like June 2005, the 9 new generation CDMA of Beijing that roll out to bring limited company of peaceful science and technology are mobile video supervisory system; 6 years in December, research of company of technology of figure of Beijing century happy figure was developed " LOTOO I-Patrol " , integrated the medium of CDMA, GPS, this locality memory that is not hard disk (Flash) , can apply in a variety of circumstances well.
Current 2.5G technology paid close attention to the confluence that is the same as TCP/IP agreement, make mobile network reachs applied platform conformity with existing Internet technology easily. The professional work of mobile data communication that IP technology and the perfect union aux will be able to with mobile technology provide all sorts of high speed to pledge high for the user quite.
