Kaer's Payphone series comprises five differentiated products, focusing on communication needs in controlled environments. Integrating diverse forms such as Video Payphone and Metal Payphone, it precisely adapts to scenarios like jails, prisons, and schools. Leveraging its SaaS hardware service provider attributes and ODM/OEM customization capabilities, it has become a benchmark for secure, controllable, stable, and reliable professional communication.
Core use cases focus on controlled and special environments, specifically addressing differentiated communication needs. In jail and prison scenarios, the Metal Payphone, with its robust metal body and tamper-proof design, coupled with multiple authentication methods such as facial recognition and card insertion verification, achieves controlled communication and eliminates security risks. In school scenarios, the device can connect to campus management systems, supporting attendance tracking and whitelisted calls, ensuring student communication security while meeting home-school communication needs. In industrial outdoor scenarios, the outdoor SIP phone and Explosion-proof payphone possess robust waterproof, dustproof, and explosion-proof performance, adapting to harsh environments such as tunnels and pipelines, ensuring uninterrupted emergency communication.
The products have clear technical differences, forming a complete functional gradient. The basic model supports card swipe/insert card calls and VoIP core functions, meeting entry-level controlled communication needs. The advanced model upgrades to a Video Payphone and a Payphone with camera, enabling dual audio and video communication with a high-definition camera, suitable for scenarios such as remote visits and video conferencing. The professional-grade Metal Payphone features an all-metal casing and armored cables, offering maximum resistance to violence and vandalism, designed specifically for high-pressure environments such as jails and prisons. The outdoor-specific model, as an outdoor SIP phone, boasts industrial-grade protection and wide temperature adaptability, supporting stable 4G/VoLTE communication. The top-of-the-line model is an Explosion-proof payphone, certified for explosion-proof operation, suitable for high-risk industrial scenarios, while retaining full-featured communication and management capabilities.
All products rely on a SaaS management platform, supporting call control, real-time monitoring, and data statistics. For commercial applications, customization services are available, allowing adjustments to authentication methods, feature configurations, and appearance design as needed. As a professional ODM/OEM service provider, Kaer can deeply integrate with different industry systems to create customized communication solutions. From secure campus communications to controlled calls in prisons, from emergency outdoor communication to high-risk scenario communications, the Payphone series, with its technological differentiation and precise scenario adaptation, has become the preferred solution for communications in controlled environments.
