Window Intercom for 2-Way Communication – Full Duplex Hands-Free System with 15″ Gooseneck Microphone

The ZDL-380B Window Intercom for 2-way Communication is a professional counter communication system designed for secure, clear, and reliable conversations between staff and customers separated by glass, acrylic, or protective barriers. Perfect for banks, ticket windows, pharmacies, hospitals, and customer service counters, it uses full duplex hands-free technology so both parties can talk and listen at the same time without interruptions.

The master operator station is compact yet durable, made from a combination of aluminum alloy and rugged plastic for long-lasting daily use. It comes with a 3-watt built-in speaker, a high-gain low-noise microphone, and a 15-inch flexible gooseneck microphone for precise operator voice capture.

Rugged build, plug-and-play setup, and compact design, this window intercom delivers a professional, reliable, and easy-to-use solution for high-traffic service points

The customer sub-station is equally compact, featuring a 2.5-inch hands-free speaker with an integrated microphone, delivering clear audio while saving valuable counter space. Both the master and customer audio channels feature separate volume controls, allowing operators to fine-tune microphone and speaker levels for different environments.

This system requires no permanent installation and sets up in just minutes. The included 6-foot audio cable with jack connector links the customer sub-station to the master station, which provides both power and audio. The master station also features an auxiliary voice recording output, enabling easy connection to an external recorder for compliance, training, or security purposes.
