AI anti-bullying measures have been implemented in primary and secondary schools and kindergartens in Zhanjiang City, with intelligent alarm devices deployed. The early warning rate for bullying in toilets and dormitories has increased by 80%, and school authorities say, 'We finally have the courage to take action,'
In response to the difficulties in detecting and intervening in school bullying in primary and secondary schools and kindergartens within its jurisdiction, Zhanjiang City, Guangdong Province, has uniformly purchased AI anti-bullying voice alarm devices from our company. The project covers 9 districts and counties, more than 300 public primary and secondary schools, and kindergartens, with over 1,200 devices installed, mainly in areas such as toilet stalls, dormitory corridors, and stair corners, which are traditionally blind spots for surveillance. Through AI voice keyword detection, one-button assistance, and cloud-based intercom, teachers can be alerted to bullying incidents within 30 seconds, resulting in a 80% increase in proactive early warnings,

Project Background: The Battle Against Bullying in Coastal Cities
Zhanjiang City is a populous city in Guangdong Province with nearly 2,000 primary and secondary schools and kindergartens (the first phase of this project focused on 300 key schools). According to the 'White Paper on the Protection of Minors' released by the Municipal Education Bureau and the Procuratorate in 2024, over 60% of school bullying incidents occur in unmonitored areas such as toilets and dormitories, and victims are too afraid of retaliation to report them. Some schools have attempted to install cameras but had them removed due to parental complaints about privacy issues. The Municipal Education Bureau decided to introduce AI anti-bullying alarm devices to achieve 'intelligent early warning' and 'one-button assistance' without infringing on privacy. After open bidding and field testing, our system stood out among five suppliers.
Selection and Deployment: Why AI Anti-Bullying Alarm Devices?
Our company has specifically developed AI anti-bullying voice alarm terminals for school settings, featuring three core capabilities:
- AI Voice Keyword Recognition: Built-in local speech recognition models that can identify preset keywords such as 'Help', 'Don't hit me', 'Teacher, come quickly', and 'Alarm' without an internet connection, triggering an alarm automatically upon recognition.
- One-Button Assistance + Two-Way Intercom: Students can press a red button to connect with the school security office or the Education Bureau's monitoring center within 3 seconds, allowing for remote intervention.
- Privacy-Friendly Design: Only voice data is collected; no cameras are used, so the installation does not cause discomfort among students. A total of 1,246 devices were deployed, distributed as follows:
- Primary and Secondary School Toilet Stalls (4-8 devices per school): 860 devices, covering approximately 200 schools.
- Boarding School Dormitory Corridors (6-10 devices per school): 280 devices, covering 35 boarding schools.
- Kindergarten Corridors and Nap Rooms (2-4 devices per kindergarten): 106 devices, used to prevent inappropriate behavior by staff and intrusions. The system uses a 4G+LoRa hybrid network (as some remote primary schools do not have fiber optic connections) and connects to the Zhanjiang City Education Bureau's **'Campus Safety Cloud Platform', integrating with the 110 emergency response center. The Safety Department of the Education Bureau can monitor the overall alarm situation in real-time on a command screen.
Key Implementation Steps
- Phased Implementation, Pilot First: Fourty schools in Xiashan District and Chikan District were selected as pilots. After two weeks of trouble-free operation, the system was rolled out to the entire city in three phases.
- Summer Vacation Construction: Construction teams worked simultaneously in July and August 2025, completing all installations and adjustments in 45 days.
- Teacher and Student Training: A 3-minute animated video in both Cantonese and Mandarin was produced and played during class meetings; each school also received training for two 'anti-bullying safety officers' (usually class teachers or security staff).
- Parent Communication: To address parents' concerns about privacy, the Education Bureau held online meetings, explaining that the devices do not record audio or video and only transmit data when keywords are detected or the button is pressed, receiving 96% parental support.
