Fengheng Technology provides professional heat dissipation solutions for the security and surveillance industry. Its products are widely used in network cameras, PTZ cameras, DVR\/NVR hard disk recorders, access control controllers, facial recognition terminals and other equipment, meeting the stringent requirements of outdoor all-weather operation for waterproof and dustproof, wide temperature range and low noise.<\/p>\n

\n

I. Four Core Pain Points of Heat Dissipation in Security Monitoring Systems<\/h2>\n

Pain Point 1: High requirements for waterproofing and dustproofing of outdoor equipment<\/h3>\n

Phenomenon:<\/strong>Outdoor cameras and PTZ cameras may malfunction after water or dust gets into their fans, causing the equipment to overheat and crash.<\/p>\n

root cause:<\/strong>Use a regular fan instead of an IP protection-rated fan.<\/p>\n

Industry Standards:<\/strong>Outdoor security equipment typically requires IP66, IP67 or higher protection ratings.<\/p>\n

Pain Point 2: Strict requirements for adaptability to wide temperature environments<\/h3>\n

Phenomenon:<\/strong>In northern winters, fans cannot start when temperatures drop below -30\u00b0C, and in southern summers, they shut down when temperatures exceed 60\u00b0C.<\/p>\n

root cause:<\/strong>The fan uses ordinary lubricating oil, which solidifies at low temperatures and evaporates at high temperatures.<\/p>\n

Industry data:<\/strong>Security equipment typically requires an operating temperature range of -30\u2103 to +70\u2103.<\/p>\n

Pain Point 3: High reliability is required for continuous operation 24\/7<\/h3>\n

Phenomenon:<\/strong>The fan stops working after 1-2 years of operation, causing the equipment to overheat and be damaged.<\/p>\n

root cause:<\/strong>Cheap oil-bearing fans have a lifespan of only 10,000 to 20,000 hours<\/p>\n

Industry feedback:<\/strong>The contractor stated that "camera fan failure is one of the main reasons for the return for repairs."<\/p>\n

Pain Point 4: The requirement for low noise in quiet environments<\/h3>\n

Phenomenon:<\/strong>The noise from the fans of indoor monitoring equipment (such as access control and facial recognition terminals) can negatively impact the user experience.<\/p>\n

root cause:<\/strong>Small fans require high speeds to achieve the desired airflow, which in turn leads to high noise levels.<\/p>\n

User feedback:<\/strong>Users of access control equipment in office buildings are complaining that "the fans are too noisy."<\/p>\n

IV. Key Considerations for Heat Dissipation Design in Security Monitoring Systems<\/h2>\n

1. Protection level selection<\/strong><\/p>\n

    \n
  • Outdoor equipment: IP66\/IP67, completely dustproof, can withstand heavy rain.<\/li>\n
  • Semi-outdoor equipment: IP54\/IP55, dustproof and splashproof<\/li>\n
  • Indoor equipment: No special protection requirements, quiet operation is preferred.<\/li>\n<\/ul>\n

    2. Wide temperature range requirements<\/strong><\/p>\n

      \n
    • Northern regions: Requires support for starting at -30\u2103 and the use of special lubricating oil.<\/li>\n
    • Southern regions: Must be able to operate at temperatures up to +70\u2103, using high-temperature resistant materials.<\/li>\n
    • Large temperature difference between day and night: condensation protection needs to be considered.<\/li>\n<\/ul>\n

      3. Reliability Requirements<\/strong><\/p>\n

        \n
      • Security equipment typically requires continuous operation 24\/7.<\/li>\n
      • We recommend a dual ball bearing fan with a lifespan of \u226550,000 hours.<\/li>\n
      • It is recommended that critical equipment support fault detection (RD signal).<\/li>\n<\/ul>\n
        \n

        V. Frequently Asked Questions (FAQ)<\/h2>\n

        Q1: What protection level is required for the fan of an outdoor camera?<\/h3>\n

        A: At least IP66, IP67 is recommended. IP67 is completely dustproof and can be submerged in 1 meter of water for 30 minutes without damage.<\/p>\n

        Q2: What should I do if my fan won't start in the low temperatures of northern winters?<\/h3>\n

        A: Select a wide-temperature model (-30\u2103~+70\u2103) and use special lubricating oil to ensure it does not solidify at low temperatures.<\/p>\n

        Q3: How often do the fans in security equipment typically need to be replaced?<\/h3>\n

        A: Original equipment manufacturer (OEM) oil-impregnated bearing fans typically last 1-2 years. Fengheng dual ball bearing fans can last 5-7 years, matching the lifespan of the equipment.<\/p>\n

        Q4: How to solve the problem of loud fan noise in indoor access control equipment?<\/h3>\n

        A: Choose a hydraulic bearing silent fan. The noise level of the Fengheng FH2510\/FH3010 hydraulic bearing series can be controlled below 20dBA.<\/p>\n

        Q5: Do you support sample testing?<\/h3>\n

        A: Free sample testing is available. We can provide original fan specifications and help you find the right upgrade solution.<\/p>\n
