Security monitoring system is the comprehensive utilization of modern computer technology,integrated circuit,network control , transmission and software technology, roughly divided into three categories:video surveillance, access control and alarm.continuously enhanced its intelligent, initiative and border aware in the new era.
Intelligent security monitoring puts forward requirements for image transmission speed, definition,video storage and data analysis,this increases the heat flux and calorific of circuit system, threatens the stability of entire monitoring system.Practically,a series of thermal fault problems will be occurred such as blurred monitoring picture, data loss, bit error and restart,due to poor heat dissipation in the core chip.
More and more 1080P,4K,8K camera are introduced to application in camera, high-definition image processing , big data computing,high power consumption and calorific value in confined quarters make the problems of thermal management and EMI shielding increasingly prominent.Simultaneously, the volatilization of thermal interface material molecules and the precipitation of silicone oil effecting on the optical lens, the low temperature resistance of the chip, all these ask for meticulous thermal designing.
In order to ensure the stable and reliable operation of the camera, it is urgent to reduce the working thermal load of the core components and alleviate the thermal stress of the circuit board.Duobo’s low volatility ,high thermal conductivity,low oil permeability and ultra soft thermal interface materials (thermal grease, silicone thermal pad, thermal putty) have perfectly assisted customers in heat dissipation case. We can evaluate the feasibility of the overall scheme in the initial design ,formulate a complete set of solution in the project and supply the corresponding materials.
