Introduction to IP Network Broadcast Intercom System

definition

IP network broadcast intercom is a new communication mode based on Internet protocol (IPv4/IPv6) and Internet technology. It combines digital audio, network transmission, e-mail, short message, video, data and other communication modes to realize the transmission of voice, image and data information between people and between people and equipment.

characteristic

1. Large scale broadcastingIt can cover the entire network and achieve network wide broadcasting.

2. Fully digital transmissionAudio and control signals are fully digitized and encoded, without being limited by transmission space and distance.

3. Efficient audio communicationIt can achieve audio communication within the area, such as elevator intercom within the community and calls between different areas, which can be quickly and effectively conveyed.

4. Diversified functionsIt has multiple functions such as real-time monitoring, broadcast notification, background music playback, emergency broadcasting, and call intercom.

5. intelligent managementIt can record call records, usage status, etc. of the area, provide data support for management decisions, and achieve more intelligent management.

6. cost savingCompared to traditional simulation systems, it is more advanced and can save equipment costs, maintenance costs, and upgrade costs.

7. Strong compatibilityThe IP network broadcast call intercom system of the steel plant can be fully compatible with the existing constant pressure broadcast system in the factory area.

Application scenarios and functions

residential area

• Real time monitoring and securityProperty management personnel can view real-time surveillance videos of the community through this system and use audio to communicate with on-site personnel, better understanding and responding to various situations.

• Efficient audio communicationImplement audio communication throughout the entire community, including elevator intercom and calls between different areas.

• Broadcast notifications and educationProperty personnel can convey important notices and information to residents in the community, such as announcements, safety education, etc., which is clearer, more convenient, and easier to manage than traditional loudspeaker broadcasting.

• Background music and radio musicProvide background music function, create a comfortable living environment, and also play radio programs or emergency broadcasts.

• intelligent managementAssist property management personnel in understanding the operational status of the community, and record data in the system to provide support for management decisions.

• cost savingCompared to traditional simulation systems, it reduces equipment, maintenance, and upgrade costs.

steel mill

• Release NoticeThe broadcasting center broadcasts superior instructions, conveys meeting spirit, and issues temporary notices through network sound columns distributed in various places, coordinating cooperation between departments.

• Regularly play background musicDevelop scheduled playback tasks, play music during commuting and rest breaks, improve the working environment for employees, and soothe their emotions.

• Regularly play the ringtone for commuting to and from workFully automatic playback of music ringtones to remind staff of commuting, with different plans and one-time tasks set according to actual needs.

• Single point partition addressing broadcastSupport single point, partition, unified timing, or manual broadcasting, which can broadcast to specific workshops, departments, and areas without affecting other departments.

• Call intercom two-way communicationThe staff of the broadcasting center can conduct paging intercom with the sub control center and network intercom panel, improving safety production and organizational management efficiency.

• Compatible with constant voltage broadcastingThe system seamlessly integrates with the existing constant pressure broadcasting system in the factory area and does not affect its independent use.

hotel

• Timed broadcastAutomatically play background music at designated times in hotel entertainment and public activity areas to enhance the atmosphere.

• partition broadcastingGroup each area of the hotel into any group, play different audio sources independently for each group, and adjust the volume separately for each area.

• District wide broadcastingPlay broadcasts, customer service notifications, etc. in various areas of the hotel.

• Broadcast shoutingEmergency notices can be directly issued for the entire district, multiple districts, and single district, and functional areas such as restaurants can broadcast speeches on their own.

• broadcast pagingThe service desk can broadcast information on lost and found items for the entire district, multiple districts, and single district.

• fire alarmCombining fire protection to achieve fire broadcasting and linkage alarm functions, and supporting neighboring area and layer alarms.

• Help intercomWhen guests or doorsteps encounter unexpected situations, they can call the monitoring center with one click through the help point terminal device or intercom extension, and have two-way communication with customer service personnel.

Terminal functional characteristics and technical parameters

Features

• One click call for helpIP-999 has a one click help call function and is equipped with indicator lights for clear and visible working status.

• long-distance transmissionSupports RS485 data transmission protocol, with a maximum transmission distance between the help panel and network player greater than 1500 meters (external DC power supply is required for distances exceeding 500 meters).

• Busy call forwardingA networked intelligent paging station with busy call forwarding function and automatic paging request for idle calls.

• Record of intercom contentThe intercom content is automatically recorded as a log, and the networked host automatically records and can be viewed.

• Device ExpansionOne networked playback terminal can expand up to 15 emergency intercom extension controllers.

• Linkage functionIt has two short-circuit inputs and two EMC linkage outputs, mainly used for linkage monitoring systems and access control systems.

• Rich interfacesEquipped with a DC24V external DC input interface, convenient for expanding long-distance transmission; Equipped with a pickup audio auxiliary output, it works in real-time with the monitoring system for recording.

• Reliable connectionUsing industrial phoenix connection terminals, the connection is reliable and stable.

• Fast response speedAdopting high-performance processors and real-time systems, the response speed of help requests is fast, environmentally friendly, and the work efficiency is high.
