With the maturity and perfection of technology, audio monitoring systems are being used in more and more fields. The role of monitoring systems is not only for security, but also for the improvement of the quality of services (especially the service industry) in various industries. positive effect.
To set up an audio monitoring system today is not a very complicated matter. With the existing monitoring system in the market and the addition of Sizheng pickups, a complete set of audio monitoring can basically meet the needs of most industries.
For the audio and video surveillance system of the motor vehicle, in addition to the security requirements, it also records the details of the carriages, including the service attitude of the flight attendants also has a normative role.
Therefore, monitoring of the audio and video surveillance system of the motor vehicle must include several areas.
1. Car audio and video monitoring

Installation situation as shown below
In addition to the above sections, depending on the function of the train, each car can be installed according to the actual situation.
The overall topology of the train audio and video surveillance system is as follows:
According to the various needs of the train, and the function of the monitoring system. The system can even be expanded and upgraded including intercom and broadcast (installing SiSheng voice intercom terminal system must support intercom and broadcast)
