Application of intelligent products

COMMUNITY

Intelligent security system from analog monitoring to digital monitoring, and then to the current network video monitoring, cameras are gradually moving towards high-definition pixels, high-end intelligent, which puts forward higher requirements for image transmission speed, clarity, video storage time and data analysis.

While improving the security system scheme, the heat flux and calorific value of the circuit system are also increasing, which brings great pressure on the manageability of the overall intelligent security thermal design scheme. As we all know, the working temperature of electronic devices directly determines their service life and stability. Heat dissipation has become an important index to measure the performance of products in the electronic industry, especially the heat dissipation of surveillance cameras. In practical application, if the core chip temperature is too high due to poor heat dissipation, it is easy to cause a series of thermal problems such as fuzzy monitoring screen, packet loss, bit error and restart, which brings great inconvenience to users.

Because the security system is composed of a variety of devices, such as infrared devices, cameras, PTZ, monitors, hard disk video recorders, monitors, matrix hosts, etc., it needs a perfect cooling solution. The thermal conductive silicone sheet can meet the heat dissipation requirements of various power security monitoring cameras. The products have passed the high temperature aging test, which can ensure the long-term operation reliability of security monitoring cameras. If the temperature of the heating electronic components (CPU / memory / video memory) on the motherboard is too high, the camera will not work stably, and it will automatically restart or crash. It will not only lose some key monitoring content, but also affect the service life of the camera. Thermal conductive silicon film can be used to assist heat dissipation and fill the gap between the heating electronic components on the motherboard and the aluminum die casting shell to transmit heat to the shell. In general, most of the pan tilt shell has no cooling holes, which leads to the poor cooling effect of pan tilt. When the camera is working, if the heat dissipation of the case is poor, the internal temperature of the case will be too high, so that the camera or other electronic equipment in the case can not work normally or be damaged. At this time, the heat conduction interface material is needed to conduct heat, so as to ensure the safe operation temperature of the product.
