Inconvenient system management

     As adopting analog video or some quantity of dividing into of the hard disk video relatively a long time, because of lacking systematism, some system can similarly remote login, but it is not only low efficiency of form of protection and management to login one by one, but also can't give attention to two or more things at the same time and inconveniently manage.

The picture is of low quality

      One of the main purposes of work of safe monitoring is when the accidental event happens, can collect evidence or distinguish through the video system, so high-definition picture quality is very important. The quality draw of existing digital recording and network transmission are standard of VCD, definition is not enough.

Can't carry through system linkage

     The traditional control type can be offered and linked the function in this locality too, but when need to cross over network to reach remote, this function is unable to realize. Because it is very all-pervading phenomenon that some undesirable elements often maliciously destroy automatic teller machine at the same time, even tramps in the street often enter the self-help bank to stay or enter to prevent sunstroke at summer, which bring more trouble to security work of bank.

      Application, popularization of the computer system, the fast development of he communication technology of the network and picture compression technique and transmission technology, make the industry of safety technique and precautions adopt the latest computer, communication and picture processing technology, and transmit the digital
