The STI-01H is a complete window intercom system developed for use in environments where communication must occur across physical barriers, such as service counters, ticket booths, banks, and healthcare reception areas. Comprising the STI-01 intercom unit and a dedicated headset, the STI-01H ensures clear, uninterrupted audio exchange between staff and customers, even in high-traffic or acoustically challenging settings. It features a touch-sensitive control panel for the operator, a dedicated agent-side microphone, and a combined microphone and speaker for the customer-side unit. The included headset enhances audio precision, making it suitable for confidential or noise-sensitive interactions.

Designed for reliability and ease of integration, the STI-01H supports organisations that require clear communication without compromising security or hygiene. Its discreet and compact form factor allows for unobtrusive installation at fixed service points, helping maintain visual and physical separation while ensuring the flow of information remains uninterrupted. The STI-01H is particularly valuable in regulated or controlled-access environments where speech intelligibility and operational efficiency are critical. By supporting direct communication through glass or partitioned surfaces, the STI-01H contributes to improved customer experience and operational effectiveness across sectors such as public service, healthcare, retail, and transportation.
