Security belongs to the category of the electronics industry, which 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 three categories: video surveillance, access control and burglar alarm. From the transformation from "visible" to "clear" to today's intelligence, the initiative of the security industry has been continuously enhanced, and edge perception + intelligence has gradually become the new goal of the intelligent security industry. Highly intelligent The era of comprehensive security has arrived.

Smart security puts forward higher requirements for image transmission speed, clarity, video storage duration and data analysis. While this combination increases the cost of the video surveillance storage solution, the heat flux density and calorific value of its circuit system are also increasing day by day, which puts enormous pressure on the manageability of the overall intelligent security solution. As we all know, the operating temperature of electronic devices directly determines their 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 faults such as blurred monitoring screen, packet loss, bit error and restart.

Cameras are gradually becoming high-end with 1080P, 4K, and 8K image quality, and high-definition pixels are getting closer. Advanced technologies such as high-definition image processing and big data computing have made thermal management and EMI shielding problems increasingly prominent. Power consumption and heat generation are large and the airtight environment puts forward higher requirements for the overall heat dissipation solution. Molecular volatilization of thermally conductive materials, precipitation of silicon oil, and silicon migration phenomena have an important impact on optical lenses; low temperature resistance of the chip becomes a heat dissipation bottleneck. How to reduce the interface Thermal resistance is an important factor to consider in thermal design.

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