The Design Principle Of Network Camera
Dec 23, 2017

With the application of large scale security system in various public places, the demand of the intelligent video monitoring system to prevent the emergency of terrorist attacks and public security is increasing. Intelligent video monitoring system based on central processing due to factors such as computing power and communication bandwidth limits, cannot be applied in large-scale video surveillance applications, and the implementation of a distributed intelligent video monitoring system is the foundation of large-scale intelligent video monitoring application. Scene perception ability of the embedded intelligent camera network is an important part of a distributed intelligent video monitoring system, the research of the embedded intelligent camera related problem is the key to the implementation of a distributed intelligent video monitoring. From this, some people in the industry also proposed the design principles for the implementation of the intelligent network camera function. The main points are as follows:
Modular design
The modular design referred to here mainly refers to the modularization of intelligent function. In the intelligent function of embedded network camera, except its basic functions, every camera needs to form a module. Other functions can be realized by separate modules. This is more flexible and convenient, and can be embedded in different modules according to the needs of actual monitoring and application, so as to reduce design and manufacturing cost, and users are willing to accept it. Therefore, modular design can not only bring greater convenience to the design and production of manufacturers, but also suitable for practical application needs.
Reliability design
It is necessary for any product to require the system to design products with reasonable structure, durable products and reliable system operation. Product must be excellent EMC design, therefore, in addition to withstand all types of electromagnetic energy EMS interference, not a failure to adapt to all kinds of bad environment, also requires its own electromagnetic interference EMI performance reach the standard, do not produce more than standard required by the electromagnetic energy.
Practical design
So-called practical design, the system is practical, simple operation, less links, easy to learn, etc., can automatically feature set expediently, linkage and guard against theft, fire prevention, entrance guard system, high degree of automation, can make the system in the actual possible infringement cases pre/alarm in time. In addition, self-check function is required, and self-check results are reported to the management center regularly and monitored by the management center for immediate maintenance.
Economic design
In consideration of system economy, in addition to considering lowering the r&d cost and production cost of the system, the cost of using the system should also be taken into account, including maintenance and spare parts cost during the use of the system. In order to achieve high cost performance, design should not blindly pursue complicated schemes. In the premise of meeting the performance index, the design of simplified scheme is adopted as far as possible, which means that the structure is simple, high reliability and low cost.
