Security monitoring

Security system belongs to the category of electronic industry, is the comprehensive utilization of modern computer technology, integrated circuit application technology, network control and transmission technology and software technology. Security products can be roughly divided into video surveillance, access control and burglar alarm three categories. From "visible" to "see clearly" change, and then to today's intelligence, the initiative of the security industry continues to increase, edge perception intelligence, has gradually become the new goal of the intelligent security industry, highly intelligent The era of comprehensive security has come.

Intelligent security puts forward higher requirements for image transmission speed, clarity, video storage duration and data analysis. While this combination increases the cost of video surveillance storage solutions, the heat flux density and heat generation of the circuit system are also increasing, which puts tremendous pressure on the manageability of the overall intelligent security solution. As we all know, the working temperature of electronic devices directly determines its service life and stability, and heat dissipation has become an important indicator to measure product performance in the electronics industry, especially the heat dissipation of surveillance cameras. In practical applications, if the core chip temperature is too high due to poor heat dissipation, it is easy to cause a series of thermal failure problems such as fuzzy monitoring picture, packet loss, error code and restart.

Cameras are gradually moving towards 1080P, 4K, 8K picture quality and other high-end, high-definition pixels are moving closer, and advanced technologies such as high-definition image processing and big data computing make thermal management and EMI shielding problems increasingly prominent. Power consumption and heat generation are large and closed environment, which puts forward higher requirements for the overall heat dissipation scheme. Molecule volatilization of thermal conductive materials and silicone oil precipitation, silicon migration phenomenon and so on have important influence on optical lens. Low temperature resistance of chip becomes the bottleneck of heat dissipation. How to reduce interface thermal resistance is an important factor to be considered in thermal design.

In order to ensure the stable and reliable operation of the camera, it is urgent to reduce the thermal load of the core components and alleviate the thermal stress concentration of the circuit board. Nuofeng Electronics' high-performance interface materials such as low volatility, high thermal conductivity, low permeability oil, and ultra-soft (thermal silicone grease, thermal silicone sheet, thermal tape, etc.) have passed high-temperature aging tests to provide professional thermal management solutions for the security industry to ensure the safety of normal operation and the reliability of long-term operation of security products.
