Does the system violate students' privacy?

This is the most important issue to consider when purchasing a anti-bullying system. Products from reputable manufacturers typically implement the following privacy protection measures:

1. Edge Computing: Audio analysis is performed locally, without continuous uploading of sound data.
2. Trigger Mechanism: Only alarm information deemed dangerous is uploaded; the original audio is not stored.
3. Area Restrictions: No privacy-sensitive footage (such as inside bathrooms) is recorded.
4. Permission Management: Alarm information is only sent to authorized personnel, with strict confidentiality.
5. Compliance Certification: The product has passed relevant security certifications and complies with the 'Personal Information Protection Law'.

It is recommended to request the manufacturer to provide a privacy protection whitepaper or relevant certification documents before making a purchase.
