(According to the actual requirements of the urban public security monitoring system, construction standards and the needs of security technology, we comprehensively use electronic information technology, computer network technology, network video monitoring technology, etc. in combination with the actual situation of the site, and carry out the system design in accordance with the premise of relevant national technical regulations and the principles of advanced, reliable, reasonable and applicable. To ensure that the intention of the builder is fully reflected, the interests of investors are protected, the benefits are maximized, and the convenience of future user maintenance, use, maintenance and system expansion is fully considered. In the project design of urban public security monitoring system, our design principle is based on the technology of "large-scale IP digital network integrated monitoring system", and its technical principle is as follows: with the development of IP broadband technology and the improvement of integrated networking technology, the demand for network integrated monitoring is increasing, the scale is also increasing, and the functional requirements are becoming more and more complex. Faced with this situation, many systems use the method of repeated investment to rebuild the private network of each system, repeatedly increase the investment cost, and manually operate between systems.)
