The shanghai border information technology ltd., located in the west park of tien tien park, has long focused on research and product development in high-end perimeter warning technology, and is a high-tech enterprise specialized in the development, production and sale of alarm system products. After many years of effort, a vibrating cable perimeter detection system with full intellectual property rights was successfully developed and its positioning error of 2 m was tested at ** a security alarm system product quality monitoring and testing test centre. At present, shanghai border information technology ltd. Has developed a unique and rigorous and efficient system of research and development, production, quality and so forth. Vibrating cable perimeter detection alert systems are highly valued by a wide range of clients with their high-precision positioning function and extremely low rates of error, and can be widely used at airports, oil depots, nuclear power plants, transformers, prisons, high-end properties, etc. The company operates with the aim of "good faith, partnership, win-winness and innovation", and client satisfaction is our standard, and we are committed to providing quality products and thoughtful services to our clients. It is our sincere desire to establish long-term friendly and cooperative relations with a wide range of clients for mutual benefit and development and to work together for a better tomorrow! • technology and services: one, the perimeter alarm system for vibrating cables, is currently ranked by its predecessor as a manufacturer of independent intellectual property, technology comparable to foreign brand names, professional advice, research and development, production, and installation of the perimeter alarm system for vibrating cables. 2. The system rejects the traditional perimeter security approach, which has been superimposed on physical equipment, and uses the technical defence tools that are primarily monitored and controlled by software for digital cross-management, while the software is based on the design principles of "high-intensity, loose-coup" and modular top-level design, ensuring that the various anti-aircraft systems operate independently and in a related cross-referenced manner, allowing for the organic integration of the various anti-aircraft systems, ensuring that the flow of information is consistent, achieving an alert and not leaving a dead corner. 3. Our practitioners have seven or eight years of experience in construction. Product characteristics: 1. The system can achieve precision in the location of alert events of up to 1 m (+2 m error). This positioning information is ranked ahead of time by controlling the mainframe connection to the cctv system, switching the matrix, controlling the smart-ball camera pointing to the alert position, and connecting the light, radio and other alarm devices. 2. A unique warning sensitivity curve effectively offsets loose and structurally different fences and adjusts their protective capabilities to the same level so that intruders can effectively alert the police when attempting to climb any fence. 3. The system is sector-by-part, per 1 metre, compared to the identification point impact and distributional disturbance, effectively filtering environmental vibrations caused by the passage of wind, rain, lightning and motor vehicles and so on, reducing the rate of error. When the vibration signal is detected, the system can determine whether the vibration signal meets the defined warning event by assessing whether the vibration signal meets the defined warning event and effectively removes the interference caused by the occasional impact of the unknown object by pre-set vibration ranges, the number of vibrations, and the time window. 5. The system allows the arbitrary number and range of perimeters to be adjusted by software to allow the perimeters to go beyond physical equipment restrictions to achieve sound perimeter dynamic control management. 6. The system's alarm cable not only provides vibration sensors to power the various modules of the system, but also completes communications between the various processors in the system and the control host, so that communications, detection and power supply are combined. 7. Special cables are simple as sensors, have high system stability and are designed to ensure good electromagnetic compatibility. 8. Our product is a better installation programme of barbed wire, which requires only a fixed belt, easy construction and maintenance。
