In fields such as security surveillance, traffic control, and large-scale venue management, high-speed dome cameras, with their core capabilities such as 360° rotation, high-speed tracking, and high-definition image transmission, have become core equipment in "visual surveillance networks." However, high-speed dome cameras generate significant heat during continuous operation. Failure to dissipate heat effectively can lead to image quality freezes and tracking delays, and can even cause internal components to burn out, directly impacting the reliability of the surveillance system. DC axial-flow fans are crucial for the stable operation of high-speed dome cameras. The Xingdong 3010 DC axial-flow fan, with its compact size, efficient heat dissipation, and high reliability, is a preferred solution for addressing these heat dissipation challenges. 1. High-Speed ​​Dome Cameras: From "Surveillance Tools" to "Indispensable for Scenario Use," Functional Upgrades Bring Heat Dissipation Pressure

High-speed domes are not simply "rotating cameras" but rather complex devices integrating precision motors, high-definition image sensors, video encoding modules, and pan/tilt control units. Their core functional requirements determine their high heat generation:

Continuous Operation: High-speed domes used in scenarios like traffic intersections and campus perimeters must operate 24/7. The motors rotate at high frequencies for extended periods, leading to significant accumulated heat from coil resistance.

High-Definition Upgrade: The widespread adoption of 4K/8K high-definition image sensors has doubled the computing load on chips, increasing the power consumption of the video encoding module and making it a major heat source.

Harsh Environment Adaptation: Outdoor high-speed domes must withstand extreme temperature fluctuations, rain, and dust. Their enclosed housing design exacerbates heat accumulation, making heat dissipation significantly more difficult.

II. Xingdong DC Axial Fan 3010: A Cooling Solution Tailor-Made for High-Speed ​​Domes
Compact Size: Fits into Tight Spaces, Perfect for Integrated Design

The ultra-thin 30mm × 30mm × 10mm size allows for easy insertion into the narrow cooling duct within a high-speed dome. It can also be flexibly installed above the motherboard, providing direct cooling to the encoder chip and image sensor, ensuring efficient cooling without affecting the layout of key components such as the pan/tilt motor and control unit. Efficient Heat Dissipation: Precisely controls core component temperatures to ensure image quality and performance. Supporting PWN speed regulation, the Xingdong DC axial-flow fan 3010 automatically adjusts speed based on the speed dome's operating requirements. It also penetrates the speed dome's internal dust screen and heat sink fins, delivering airflow of 2.45-4.23 CFM, preventing airflow short-circuiting and ensuring efficient heat dissipation.

High Reliability: Resists harsh environments and reduces maintenance. Supporting IP68-rated protection, it is dust- and water-resistant, making it suitable for areas prone to rain, dust, and fog. The housing is made of UL 94-V0-rated high-temperature-resistant material to prevent deformation in summer heat. The coil utilizes low-temperature copper wire to ensure normal startup in low-temperature environments. Dual ball bearings offer lower wear than conventional bearings and a lifespan of over 80,000 hours.
As speed domes evolve towards AI intelligent tracking, multispectral monitoring, and edge computing, the power consumption of their internal components continues to increase, further intensifying cooling requirements. The Xingdong 3010 DC axial-flow fan, with its compact design, efficient heat dissipation, and high reliability, precisely matches the application requirements of high-speed dome cameras. It effectively controls internal temperature, ensuring high-definition image quality and intelligent tracking performance, while also reducing equipment failure rates and maintenance costs, extending service life.

Due to its wide adaptability in performance and operating voltage (e.g., 5V/12V), DC axial-flow cooling fans are suitable for a variety of electronic devices, such as power supplies, smart appliances, racks, cabinets, and various industrial equipment. When selecting a fan, we recommend choosing the appropriate model and specifications based on the device's cooling requirements, space constraints, and fan quietness requirements.
