EPTFE Adhesive Membrane For Outdoor Security Facilities Blance Pressure Difference

As technology advances and people's awareness of safety increases, the application of security cameras is becoming increasingly widespread. Nowadays, security cameras are found in every aspect of people's lives: courtyards, streets, residential areas, squares, parks, factories, supermarkets, hospitals, and more. The functionalities of these cameras have also become richer; beyond traditional video capture, many cameras now feature audio capture, sound alerts, two-way communication, and other functions.

The lifespan of security equipment is influenced by its external environment, which mainly includes the following aspects:

Climatic conditions: The climatic conditions where security equipment is located significantly affect its lifespan. For instance, high temperatures and humidity can accelerate the aging of electronic components inside the equipment, thereby shortening its lifespan. Therefore, security equipment needs to have good weather resistance to operate stably under various climatic conditions.

Air quality: Pollutants and particulate matter in the air can damage security equipment. Dust and corrosive gases in the air may enter the gaps of the equipment, causing damage or corrosion to the internal parts. Hence, security equipment needs to be dustproof and corrosion-resistant to extend its lifespan.

Security monitoring devices that are ubiquitous need to capture nearby scenes at any time. Traditional solutions involve sealing the entire device with sealant and sealing rings to prevent rainwater from entering. However, if in a humid environment, significant changes in external temperature can cause fogging on the surveillance lens due to condensation phenomena. Internal pressure differences and condensation can reduce the reflectivity of the lens and distort images, leading to unclear capture by the surveillance camera. In the case of complete sealing, using waterproof breathable and water-resistant acoustic products can quickly help remove internal moisture from surveillance cameras, solving the problem of condensation and providing strong support for the efficient operation of the product. Surveillance cameras often have openings at the positions corresponding to microphones and speakers on the shell to connect with the outside world and facilitate sound transmission. At these openings, it is necessary to apply waterproof breathable membranes and waterproof acoustic membranes to protect microphones, speakers, and other components from dust and water. At this point, using ePTFE microporous membranes, which have excellent waterproof, dustproof, and anti-fouling properties while maintaining low sound loss and low distortion audio characteristics, is beneficial.

XINNA introduces ePTFE waterproof breathable adhesive membranes with the following characteristics:

• Waterproof and dustproof safety levels reach IP65~IP67
• Hydrophobic, oleophobic
• Promotes the dissipation of moisture and vapor
• Extremely chemically inert
• Will not peel off UV resistant
• Withstands extreme temperatures

The advantages of using XINNA's waterproof breathable adhesive membrane:

1. Waterproof and breathable, reduces condensation: The breathable membrane possesses waterproof and breathable characteristics, effectively preventing moisture and humidity from entering the device while allowing internal moisture to be expelled through the membrane. This maintains a dry environment inside the device, which can extend its lifespan and ensure that captured system images are clearer and more stable.
2. Dust and contaminant protection: The breathable membrane can block dust, particulates, and contaminants from entering the device, while still allowing internal moisture to escape through the membrane. This helps to keep the device clean and reduces the frequency and cost of cleaning and maintenance.
3. Reduces temperature fluctuations, avoids premature sealing failure: The breathable membrane helps to balance the temperature inside and outside the device, preventing pressure differences caused by temperature changes, thereby reducing the risk of damage to internal components. Especially in high-temperature environments, the breathable membrane can release heat to maintain the normal operating temperature of the device.
4. Prevents pressure accumulation, balances internal and external pressure differences: It prevents the accumulation of air pressure inside the device that could lead to instability or damage. This is crucial for some sealed devices or security equipment in explosive environments.
