According to the school’s construction goals for safe campus, digital campus, and smart campus, the school’s video intercom broadcast system needs the following in school. In the school’s teaching building, comprehensive office building, laboratory building and other areas, teachers and students encounter emergency , You can use the visual intercom terminal to ask the staff on duty for help intercom, and you can view the school’s published information with pictures and texts at any time, and can be connected with the campus monitoring system, and unified control and management on the campus comprehensive management platform.

Multi-level management

According to the requirements of the school's visual intercom broadcasting system, follow the system structure and management ideas of clear responsibilities, collaborative management, and level-by-level supervision, which can be set through the school-grade-class level.

Two-way video intercom

School visual docking terminal. When teachers and students in the school press the call alarm button when they encounter an emergency, the management control room can see the surrounding situation of the visual intercom terminal through the IP network visual console, realizing visual two-way communication. speak.

Monitoring function

In the case of permission, the monitoring center can monitor the situation around the video intercom terminal.

Multi-party call

Support full-duplex hands-free calling (with howling suppression and echo cancellation), clear and stable voice. Multi-party calls are subdivided into conference mode, command mode, and response mode, making it easier to dispatch communications.

Audio recording function

When the school management center personnel broadcast or talk, the system server can automatically record the broadcast content or the content of both parties' speeches, and the audio and video files are automatically saved on the server for subsequent reference.

Broadcasting, missions, music

The school center (sub-control room) can broadcast the entire area (teaching building, office building, etc.) to the area (teaching building, office building, etc.).

KSDK secondary development (system linkage)

SDK secondary development kit (third-party software): Provide secondary development kits, link with third-party platforms (video surveillance, etc.) to achieve linkage between various subsystems, and fully realize the interconnection of information construction.

· Integrated

The school visual intercom system can be well integrated with voice, video and other platforms, integrating intercom, learning, office, and publicity, and can seamlessly integrate various systems and access the school's comprehensive management platform.

· Digitizing

The school video intercom system uses TCP/IP network technology to convert audio signals into digital signals for transmission, which greatly improves the anti-interference performance of the system. At the same time, the MP3 compression algorithm technology is adopted to reduce the occupied space of the audio signal and improve the transmission speed and stability of the signal. After the sound is transmitted over a long distance, the sound quality can still be guaranteed.

· Networked

Connect with the duty room of the nearest police station through the school’s campus network and the Internet to realize borderless broadcast intercom. It solves the problems of complex transmission lines and short transmission distances of traditional broadcast intercom.

· Intelligent

The school video intercom system implements a highly intelligent management mode. The user only needs to operate and broadcast each zone in the main control room. The zone terminal equipment automatically performs the main control broadcast task, and each zone can operate independently. According to actual needs, it can access local audio sources to broadcast.
