Conductive Silicone Foam for EMI Shielding in Industrial Communication Equipment | Konlida

Rising Demand for EMI Shielding in Smart Security Devices

With the rapid growth of smart city infrastructure, security devices such as IP cameras, facial recognition access control systems, and intelligent monitoring terminals have become essential for urban safety, residential protection, and commercial surveillance.

These devices rely heavily on wireless communication, HD image transmission, and AI-based recognition algorithms, making them increasingly sensitive to electromagnetic interference (EMI).

In this context, EMI conductive foam emerges as a crucial shielding material due to its excellent shielding effectiveness, compressive resilience, and adaptability.

If you are not yet familiar with the fundamental properties of conductive foam, we recommend starting with Working Principle and Core Advantages of Conductive Foam ↗, which explains the basic shielding mechanisms relevant to EMI conductive foam.

EMI Shielding Needs in Smart Security Devices

Smart security equipment typically operates in electromagnetically complex environments:

• Outdoor installations: Near base stations and power equipment, exposed to external interference.

• Wireless communication modules: Wi-Fi, Bluetooth, and 4G/5G signals interact frequently, increasing the risk of internal interference.

• HD image transmission: Video signals may be disrupted, causing blurred images or interrupted feeds.

• AI recognition modules: Functions such as facial recognition or behavior analysis demand stable, interference-free data.

Thus, selecting a reliable EMI shielding material with strong adaptability and easy installation is essential.

Why EMI Conductive Foam Is the Ideal Choice

Konlida’s EMI conductive foam is widely adopted in smart surveillance and access control systems thanks to its:

• Effective Shielding Performance – 40–70 dB attenuation across 1–6 GHz.

• Excellent Compression & Resilience – Fits irregular structures like camera housings and module joints.

• Easy Processing & Installation – Supports adhesive backing, die-cutting, and stamping for mass production.

• Strong Weather Resistance – Performs reliably in environments ranging from -20°C to 120°C.

• Cost Efficiency – More affordable than silicone foam for mid-frequency shielding applications.

Typical Application Scenarios

1. Smart Camera Housing Shielding
   EMI conductive foam gaskets seal camera enclosures, providing both dustproofing and EMI shielding, ensuring stable image transmission and accurate AI recognition.

2. Facial Recognition Access Control Systems
   Used between modules (camera, AI chip, communication unit) to reduce signal crosstalk and improve recognition accuracy.

3. Monitoring Terminal Connectors
   HDMI, USB, and power interfaces are common EMI leakage points; foam gaskets provide stable shielding for uninterrupted data transmission.

4. Smart Door Lock Communication Modules
   Ensures reliable operation of Bluetooth, Wi-Fi, or Zigbee modules by shielding them from external interference.

EMI Conductive Foam Selection Guidelines

When selecting EMI conductive foam for smart security devices, consider:

• Shielding Frequency Range – Match coating type to device operating frequency.

• Compression & Resilience – Maintain performance after long-term use.

• Environmental Compliance – Prefer RoHS-certified, low-VOC products.

• Processing Compatibility – Support for die-cutting, adhesives, and stamping.

• Cost Management – Carbon-based or nickel-copper foams are suitable for mid- to low-frequency shielding needs.
