Automated broadcast scheduling, instant intercom communication, and continuous supervision of meetings help staff work faster and more effectively.
All system operation data is stored in one place and managed in a unified way, with fast and flexible multi-level search.
One-touch emergency alarms, multi-party emergency coordination, precise broadcast control, and full-process monitoring of inmate meetings greatly reduce the risk of sudden incidents.
Breaks system silos and enables smooth connection between broadcasting, intercom, and meeting supervision systems.
In cells, workshops, and other areas, inmates’ daily requests (such as equipment failure) or emergency needs (such as conflicts or illness) rely on limited call channels. Busy lines or missed calls can cause slow response and create safety risks.
Prison systems often work separately. Broadcast content, call logs, and meeting recordings are stored in different places. Without a unified platform, data search and review are slow and inconvenient.
Prisons have many meeting windows but limited officers. It is hard to monitor all meetings at the same time. Risks such as collusion or passing illegal information cannot be controlled in real time.
Different brands and protocols are used across prison systems. They are hard to connect and upgrade, making it difficult to build an integrated supervision system.
The SPON prison solution is built on an IP-based network. It seamlessly integrates the broadcasting, intercom, and meeting management systems to create an all-in-one supervision system with a unified platform, tiered control, and full-area coverage.










One-touch help and guaranteed response
Broadcasting, intercom, and visits on one platform for unified management
Full data records with traceable logs

1. If conflicts occur between inmates, or if an inmate has daily needs such as feeling unwell or damaged items in the cell, they can press one button on the IP intercom to call the duty office officer. This ensures the request is reported quickly.
2. If the duty office IP paging microphone is busy or not answered in time, the call is automatically forwarded to the control center to ensure a fast response.

1. Officers can answer calls from inmate cells and view live video at the same time, enabling quick and accurate response.
2. Officers can silently monitor inmate conversations and behavior to understand risks early and take action when needed.
3. Officers can remotely control cell doors through the IP paging microphone

1. Officers can receive calls that are busy or unanswered at duty offices in each prison block, ensuring inmate requests are handled on time.
2. Officers can use the IP network paging microphone for daily communication and emergency command and dispatch, improving response speed and coordination.

1. After family members complete visit registration, they communicate with inmates through two-way voice at the assigned meeting window.
2. The full meeting process is supervised. Officers can monitor key meeting windows one-by-one, or rotate monitoring across multiple regular windows. If abnormal behavior such as collusion or passing illegal information is detected, officers can issue a voice warning or immediately cut off the call. All meetings are recorded and stored, ensuring full traceability and strong meeting security.

1. In the workshop, inmates can use the IP intercom to make a one-touch call to the duty office for daily issues (such as equipment failure) or emergencies (such as illness, injury, or safety threats), ensuring fast reporting.
2. If the duty office IP paging microphone is busy or not answered in time, the call is automatically forwarded to the control center to ensure timely response.

Public area speakers can play scheduled broadcasts such as daily bells and education programs automatically, with no manual action needed. In emergencies, officers can override the schedule with one click to deliver priority alerts or evacuation instructions.
