Fiber Perimeter Intrusion Detection Systems

Fiber Perimeter Intrusion Detection Systems from Raycom Co., Ltd use distributed acoustic sensing (DAS) technology to detect physical disturbances along a fiber optic cable installed along fences, walls, or ground boundaries. The system identifies intrusion events by analyzing phase shifts and backscatter patterns in the fiber, with a detection range of up to 40 kilometers per channel and zoning capability in 10-meter segments. It operates without power along the perimeter, relying solely on laser interrogation units at the endpoint, making it immune to electromagnetic interference and suitable for high-risk environments.

The fiber cable is typically armored with polyethylene sheathing and rated for outdoor use in temperatures from -40°C to +70°C. Standard installation includes single-mode G.652.D fiber with a core diameter of 9 microns, compatible with industry-standard OTDR and DAS interrogators. The system does not require active sensors along the perimeter, reducing points of failure. Typical industry applications include military bases, critical infrastructure, and high-value industrial sites where false alarm rates must be below 5% per 100 km per month.

Buyers commonly deploy these systems for long-range perimeter monitoring where traditional sensors or cameras are impractical. End users include defense contractors, utility operators, and logistics hubs with expansive perimeters. The system integrates with third-party video management and alarm platforms via TCP/IP or Modbus protocols. Packaging includes spooled fiber in protective cases, with interrogator units shipped separately. Lead time is confirmed upon order, and delivery terms are negotiable under FOB Beijing or CIF terms.

Raycom Co., Ltd is based in Beijing, China, with its registered office at 3-4 Fl Tower 1 Building A, No.27 Chuangxin Road, Changping Science Park. The company specializes in perimeter security systems using fiber optic sensing technology. Its profile indicates active engagement in technical documentation and product specifications, though no certifications, certifications, or client lists are disclosed. Response rate and average response time are not available on the listing, indicating limited customer service interaction recorded on the platform.

The company does not claim manufacturing scale, years in operation, or export volume. It does not list any third-party certifications such as ISO, CE, or UL. The absence of these claims suggests a focus on technical delivery rather than marketing claims. Buyers should verify compliance with local regulatory standards independently. The supplier’s physical address and product focus confirm its operational base in China’s technology corridor, but no additional details about workforce, R&D, or production capacity are provided.
