The Fire Rescue Brigade of Liaocheng Economic and Technological Development Zone is positioned as the main force and national team for emergency rescue. It is responsible for preventing and resolving major safety risks and responding to and handling various disasters and accidents. The establishment of this brigade is of great significance for further enhancing the professional honor and sense of belonging of the fire rescue personnel, fully leveraging its role as the main force and national team for emergency rescue in fighting fires and rescue operations, and accelerating the regularization, professionalization and vocationalization construction of the fire rescue force. 

The Fire Rescue Brigade is a team responsible for economic development and providing citizens with fire safety services. It undertakes three tasks in the city: fire prevention and extinguishing, rescue and disaster relief, and counter-terrorism and bomb disposal. It has 49 subordinate brigades. Due to the large scale and large number of personnel in the fire force, there are numerous training and education, meetings and exchanges, and the remote communication equipment needs to be continuously improved. Therefore, an efficient, timely, accurate, and flexible remote communication application is needed. 

Due to the large scale of the fire department and the numerous meetings held, each fire brigade often needs to report their work to the headquarters on a regular basis. Moreover, there are also frequent need for immediate meeting exchanges among fire stations and major brigades. Therefore, the fire brigade's integrated video conference system can conduct multi-party high-definition video conferences and can also display high-definition auxiliary streams, facilitating work reporting and communication. 

2. To better manage fire prevention and handle on-site emergency situations, the emergency system of the fire department has been extended to every fire truck. Through the video conferencing system on the fire trucks, the situation at the disaster site can be transmitted to the fire command center, enabling the center to promptly grasp the current fire situation at the scene and promptly organize and dispatch fire-fighting forces. 

The mobile command vehicle is unable to deploy a wired network. However, the Chevlen video conferencing equipment can transmit high-definition images and audio in real time via 3G/4G networks while in continuous motion, promptly relaying the situation at the disaster site to the command center.
