With the continuous development of social economy, the soaring prices of raw materials and the increasing technological content of products, the management of raw materials, R & D and technology of products produced by factories is becoming more and more important.Relying on the strengthening of management within the factory, the self-consciousness of workers and the human factors of security, has been unable to meet the needs of enterprise development.Factory anti-theft security inspection mainly refers to the safety protection strategy of manufacturers for products containing metals and trace precious metals.For example, the metal chips of the computer factory, the metal chips of the cell phone factory, the electronic products of the electronics factory, and the cables of the wire and cable factory are stolen by a very few employees with low ideological awareness, or in the R & D departments and special security departments that require strict confidentiality.If an accident or theft occurs, it will bring huge losses to the production enterprises, so it is urgent to prevent the loss of products and raw materials by scientific management means.On the premise of not infringing on the personal rights of each employee, we should use scientific and technological means such as security inspectors and metal detectors to carry out production management, and effectively combine civil air defense and technical defense to avoid the loss of enterprise property and technology.
