Campus Broadcasting · Start with Everyday Usability

Do daily broadcasting well, and also leave good interfaces for two-way collaboration

From the broadcast center to classrooms, corridors, and playgrounds, first ensure that audio tasks, zones, and personnel responsibilities are clear, then add two-way return audio, group conferences, and AI as needed. Different areas use different nodes, with no indiscriminate audio pickup.

01 / DUOCAST

Common broadcast tasks covering the campus

01

Bell Ringing and Daily Notifications

Configure tasks based on the school calendar, daily schedule, and zones, and set up processes for holidays, temporary class adjustments, and manual suspension to prevent erroneous tasks from being broadcast school-wide.

02

Listening Comprehension Test

Verify audio source authorization, file checksums, playback schedules, zones, volume, and monitoring links; conduct trial broadcasts and fault drills in advance; exam organization regulations take precedence.

03

Classroom Teaching Amplification

TP-DW01 or TP-DW02 together with a matched microphone forms a planned classroom link, clarifying the priority and restoration method of the teacher's microphone when broadcasting is inserted.

04

Playground and Public Areas

TP-DN02 works with TP-DN13, or choose TP-DN11, 12, or 14 depending on the scenario; load, coverage, protection, and installation must be measured on site, and it is not assumed that all public areas have backhaul.

05

Emergency Notification and Two-Way Calling

TP-DN04, TP-DN05, and TP-DN07 can be configured for paging and linkage according to the project interface plan. When a teacher initiates a call, the information recipient and handling process must be clearly defined, and this cannot replace legally mandated alarm channels.

02 / DUOCAST

Select a planning combination based on school conditions

Class size is used only for demand tiering and is not a tested capacity commitment. All of the following require additional network, power, speaker load, and software licensing provisions.

Single-campus basic type (≤30 classes, selection example only)TP-DS01 + TP-DS06 + TP-DN01 or TP-DN14 + TP-DW01, TP-DW04Divide network playback and wireless amplification tasks on a per-classroom basis; do not double-count endpoint capabilities

Priorities must be configurable and also drillable.

01

Establish a task and responsibility list

Define daily music, schedule, exam, paging, meeting, and emergency tasks, with the school approving their priorities and authorized personnel.

02

Verify insertion and forced switch rules

Emergency linkage priorities shall be determined according to the applicable project specifications, and the interruption behavior for regular broadcasts and conferences shall be verified; fire compliance shall not be claimed solely on the basis that the equipment supports the interface.

03

Drill Exceptions and Recovery

Test task conflicts, false triggers, network failures, and primary-backup switching within the same zone, verify recovery after interruption or manual confirmation, and do not automatically replay inappropriate content.

04

Leave a traceable record

Record the task, operator, time, scope, and execution results in the plan; logs follow least privilege and limited retention, and no unrelated teacher or student voice is additionally collected.

04 / DUOCAST

Three types of interrupts, three sets of inspection methods

ScenarioBehavior to be verifiedPrerequisites
Campus network outageLocal wireless amplification, retention scope of locally issued tasksMatched receiver for continuous power supply; with cache, tasks, and correct time
Server unavailableActive-standby takeover, terminal offline tasks, and post-recovery statusRedundancy and synchronization have been configured, with clear fault detection and manual takeover procedures.
Mains power interruptionBackup power supply scope and duration for critical linksMeasure the actual total load of servers, switches, power amplifiers, and terminal devices; retain other emergency notification methods
05 / DUOCAST

On-site return transmission is not default all-day recording

Prioritize teaching and research tasks that are actively initiated and explicitly authorized by teachers. Before enabling remote classroom observation, data transmission, or recording, clearly define the processing purpose, applicable legal basis, notification methods, access permissions, and retention periods; when minors are involved, fulfill applicable requirements such as guardian consent.
Deploying listening or collection devices in highly private spaces such as restrooms, changing rooms, and dormitory bedrooms is prohibited. Security incident detection in public areas also requires a necessity and personal information protection assessment, and indiscriminate continuous recording must not be conducted. Automatic alerts are only prompts and must be verified by authorized personnel; they cannot automatically determine that bullying has occurred.
Starting from the real needs of the campus

Turn "audible" into "conversational."

Tell us the number of classrooms, network conditions, and usage scenarios, and let's determine the right broadcast, conferencing, and AI configuration together.
