The development of video surveillance technology is in two aspects of the pressure. The one hand, the role and functions of the monitoring system is recognized by all walks of life have shown a huge demand, video surveillance has become a social, environmental monitoring, business regulation, state control, in particular, is the preferred and necessary means of public affairs management.
On the other hand, exposed the shortcomings of the early projects and built systems reflect the many technical problems and shortcomings, the system is running and management of the problem is not well resolved. The huge amount of information obtained by the system, but it is in low level of application. The system input in the construction, real benefits and expectations of the difference larger. Obviously, the pressure in this respect is to monitor the development of the negative factors.
The interaction of these two pressures, combined with video technology, the rapid development of new technologies are emerging, and its maturity and the actual effect is not proof of the practice, resulting in the user during the selection hesitant. Some commented that the current video surveillance system construction is in dilemma, indecisive entangled state.
