However, while improving the transport capacity and speed, there is a higher demand for safety issues. After all, rails such as high-speed railways and passenger dedicated lines are mostly constructed on viaducts, tunnels, and so on. These are locations with a high degree of risk. Therefore, there must be better security and better equipment support for railway construction. At present, the most commonly used measure is the use of railway-specific video surveillance systems to monitor the situation along railways and at sites such as stations and unloading stations. 
Taking into account the special circumstances of the railway, so the railway dedicated video surveillance system is commonly used wireless and wired two systems combined, in the railway along the use of wireless video surveillance system, in the site platform, unloading stations and other places are using cable video surveillance system.
The main functions of the railway dedicated video surveillance system: 
1. All-day red wireless video surveillance along the railway line, using industrial-grade wireless bridges and industrial-grade wireless surveillance cameras, can transmit surveillance video back to the railway management center in the field 24 hours a day.
In order to cope with various harsh field environments, wireless bridges and surveillance cameras used along the railway lines must have industrial-grade workmanship. Wireless bridges and wireless surveillance cameras should have dust and water resistance above IP67, high temperature and low temperature resistance, and high anti-interference ability.
It is recommended to use ST5801GB this industrial-grade wireless bridge, which is a multi-hop and low-loss MESH network wireless bridge, is very suitable for the railway transmission distance, monitoring point distribution environment. Point-to-point transmission distance of up to 30 kilometers, transfer multi-hop transmission can be transmitted more than 100 kilometers.
Wireless surveillance cameras are equipped with high-definition web cameras with 720P or more, which support remote monitoring and convenient remote control for operators. And must have fog, strong white balance, night vision and other functions for daytime, dark night and all kinds of weather.
2. The local railway management center can monitor the railway road conditions in real time through the client of the video surveillance system. In the monitoring command center, video integrated management software is used. On the client side, simultaneous monitoring of multiple screens can be performed simultaneously, and video and remote operations can also be performed. Surveillance cameras. When a dangerous road condition is found, the wireless transmission system can promptly issue instructions for emergency operation. Teng Yuan's wireless video surveillance system will be equipped with the corresponding client operating software, users can log on, real-time remote monitoring of each surveillance camera. In the surveillance video recording, storage and other functions, you can use the network hard disk recorder for real-time recording, you can also connect the Internet to monitor the image synchronization on the network server.
3. Whether in the train, on the track, or in the event of emergencies at stations, unloading yards, etc., railway management personnel can obtain relevant information through the surveillance camera in time and perform real-time video recording through the system to intelligently record the occurrence of events. The time and place are convenient for railway management personnel to respond in a timely manner and report the situation to a superior or local* system for smart job linkage. Afterwards, forensics and analysis can be conducted through the system.
The train and railway management center is equipped with the ST6242CZ-HD COFDM mobile audio and video transmission system. When an emergency occurs, the mobile audio and video transmission system can be used for audio and video communication, timely advice or instructions to avoid deterioration of the situation.
ST6242CZ-HD is a vehicle-mounted COFDM high-definition two-way voice mobile wireless transmission equipment, characterized by stable transmission of audio and video signals in high-speed movement, and the use of narrow-band transmission technology, in the case of transmission of large amounts of data is only taking up a small amount of Bandwidth improves overall transmission performance. In the sight-seeing environment, it can transmit 100 kilometers.
