In today's rapidly evolving world, the need for advanced and specialized monitoring systems has become more critical than ever. As public safety concerns continue to rise, video surveillance is being increasingly deployed across various sectors of society. Each industry—such as public security, railways, prisons, environmental protection, and schools—has unique requirements beyond basic functions like video storage and remote control. Traditional, one-size-fits-all monitoring solutions are no longer sufficient to meet these diverse needs. The demand for high-definition video surveillance systems is growing across all industries, and this trend is especially evident in the transportation sector.
When it comes to subway monitoring systems, it's essential to recognize the challenges involved. Subways are often targeted by terrorists due to their high population density. High-definition video recording plays a crucial role in capturing clear footage after an incident occurs. Subway operations manage terminal devices and prioritize control to ensure efficient resource sharing. The use of all-IP high-definition cameras simplifies network setup, and each station’s TV monitoring system operates independently, enhancing reliability, availability, and maintainability.
As shown in the diagram, Beijing Tianyixuan has introduced the SDI uncompressed high-definition optical transceiver model TY-HFS1020 as a core solution to address the high-definition video challenges in metro surveillance. This device enables the transmission of standard 3G/HD/SD-SDI signals over a single fiber optic cable over long distances. It features LED indicators that display the status of power, video, and light signals. The 3G/HD/SD-SDI optical transceiver consists of two units: a transmitter and a receiver. The transmitter supports SDI loop output, and it is compatible with SMPTE 292M and SMPTE 295M standards, supporting data rates of 143Mbps, 270Mbps, 1.483Gbps, 1.485Gbps, and 3Gbps. The high-definition signal is transmitted through an SDI matrix, ensuring crystal-clear visuals on high-definition screens. This technology meets the demands of various industrial applications and is widely used in live television broadcasting, high-definition video conferencing, and high-definition video surveillance.
It is an ideal choice for designing a high-definition TV monitoring system in subways. For more details, please visit our official website.
