Custom Applications of Shielded Cables in Security Installations

Shielded cables have become increasingly vital in security installations to safeguard sensitive data and ensure uninterrupted operation of security systems. Their unique construction provides enhanced protection against electromagnetic interference (EMI) and radio frequency interference (RFI), making them ideal for critical security applications. This article explores the diverse custom applications of shielded cables in security installations, highlighting their advantages and specific use cases.

Perimeter Intrusion Detection

Custom shielded cables are essential for perimeter intrusion detection systems that rely on sensors, cameras, and other devices to detect unauthorized entry. The shielding prevents EMI from interfering with sensor signals, ensuring accurate detection and timely alerts. The rugged construction of shielded cables withstands harsh outdoor environments, maintaining reliable operation in extreme weather conditions.

Access Control Systems

Shielded cables play a crucial role in access control systems that regulate entry to restricted areas. They connect door locks, card readers, and other access control devices, transmitting data securely and reliably. The shielding mitigates EMI and RFI, preventing interference from external sources that could compromise the system’s integrity.

Surveillance and Video Monitoring

Shielded cables are indispensable for surveillance and video monitoring systems that capture and transmit video footage for security purposes. The shielding minimizes noise and interference, ensuring clear and uninterrupted video transmission. This is particularly important in high-noise environments, such as industrial facilities or areas with heavy electrical equipment.

Fiber Optic Communication

Fiber optic cables, which are inherently immune to electromagnetic interference, are often preferred for security installations where high data rates and long transmission distances are required. Shielded fiber optic cables provide an additional layer of protection, preventing physical damage and ensuring uninterrupted communication even in areas with high levels of EMI.

Data Protection

Shielded cables are vital for protecting sensitive data transmitted over security networks. The shielding prevents eavesdropping and data breaches by blocking unauthorized access to network signals. This is essential for security systems that transmit confidential information, such as access credentials, video footage, or security logs.


Custom shielded cables offer a range of applications in security installations, providing enhanced protection against EMI and RFI, ensuring reliable operation, and safeguarding sensitive data. Their rugged construction and specific design features make them ideal for perimeter intrusion detection, access control, surveillance, fiber optic communication, and data protection. By leveraging the benefits of shielded cables, security professionals can enhance the effectiveness and reliability of their security systems, protecting against threats and ensuring the safety of people and property.
