The STI-01B is a complete window intercom system developed to improve spoken communication in environments where physical barriers such as glass screens impede direct interaction. Designed for use at service counters, reception areas, and customer service points, the STI-01B supports clear, two-way audio transmission between staff and visitors. It comprises the STI-01 intercom unit with a touch-sensitive agent-side interface, a directional microphone for the staff operator, and a combined microphone and loudspeaker module for the customer. An integrated magnetic induction loop enables compatibility with hearing aids, thereby ensuring that the system meets accessibility standards and serves a broader range of users.

The system ensures that speech remains audible and intelligible even in noisy environments, enhancing service quality and reducing communication errors. With its discreet design and emphasis on inclusive functionality, the STI-01B contributes to a more professional and accommodating service experience. Its robust performance and ease of integration make it a dependable choice for institutions seeking to maintain clear and accessible communication in customer-facing roles.
