I. Four Core Pain Points of Heat Dissipation in Security Monitoring Systems
Pain Point 1: High requirements for waterproofing and dustproofing of outdoor equipment
Phenomenon:Outdoor cameras and PTZ cameras may malfunction after water or dust gets into their fans, causing the equipment to overheat and crash.
root cause:Use a regular fan instead of an IP protection-rated fan.
Industry Standards:Outdoor security equipment typically requires IP66, IP67 or higher protection ratings.
Pain Point 2: Strict requirements for adaptability to wide temperature environments
Phenomenon:In northern winters, fans cannot start when temperatures drop below -30°C, and in southern summers, they shut down when temperatures exceed 60°C.
root cause:The fan uses ordinary lubricating oil, which solidifies at low temperatures and evaporates at high temperatures.
Industry data:Security equipment typically requires an operating temperature range of -30℃ to +70℃.
Pain Point 3: High reliability is required for continuous operation 24/7
Phenomenon:The fan stops working after 1-2 years of operation, causing the equipment to overheat and be damaged.
root cause:Cheap oil-bearing fans have a lifespan of only 10,000 to 20,000 hours
Industry feedback:The contractor stated that "camera fan failure is one of the main reasons for the return for repairs."
Pain Point 4: The requirement for low noise in quiet environments
Phenomenon:The noise from the fans of indoor monitoring equipment (such as access control and facial recognition terminals) can negatively impact the user experience.
root cause:Small fans require high speeds to achieve the desired airflow, which in turn leads to high noise levels.
User feedback:Users of access control equipment in office buildings are complaining that "the fans are too noisy."

IV. Key Considerations for Heat Dissipation Design in Security Monitoring Systems
1. Protection level selection
- Outdoor equipment: IP66/IP67, completely dustproof, can withstand heavy rain.
- Semi-outdoor equipment: IP54/IP55, dustproof and splashproof
- Indoor equipment: No special protection requirements, quiet operation is preferred.
2. Wide temperature range requirements
- Northern regions: Requires support for starting at -30℃ and the use of special lubricating oil.
- Southern regions: Must be able to operate at temperatures up to +70℃, using high-temperature resistant materials.
- Large temperature difference between day and night: condensation protection needs to be considered.
3. Reliability Requirements
- Security equipment typically requires continuous operation 24/7.
- We recommend a dual ball bearing fan with a lifespan of ≥50,000 hours.
- It is recommended that critical equipment support fault detection (RD signal).
V. Frequently Asked Questions (FAQ)
Q1: What protection level is required for the fan of an outdoor camera?
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.
Q2: What should I do if my fan won't start in the low temperatures of northern winters?
A: Select a wide-temperature model (-30℃~+70℃) and use special lubricating oil to ensure it does not solidify at low temperatures.
Q3: How often do the fans in security equipment typically need to be replaced?
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.
Q4: How to solve the problem of loud fan noise in indoor access control equipment?
A: Choose a hydraulic bearing silent fan. The noise level of the Fengheng FH2510/FH3010 hydraulic bearing series can be controlled below 20dBA.
Q5: Do you support sample testing?
A: Free sample testing is available. We can provide original fan specifications and help you find the right upgrade solution.
