Window Intercom FAQs

A window intercom, also known as a glass talker, is a two-way intercom for communication through glass or a barrier. Window intercoms enable clear communication between staff and customers, while keeping people physically separated for safety, security, or environmental control reasons. Window intercoms are used in ticket booths, bank teller windows, reception counters, pharmacies, service stations and other customer service applications.

Window intercoms consist of a master unit with a microphone and speaker for the staff side and a substation for the customer side. Some units include hands-free, noise cancellation and volume control features for clear communication in noisy environments.

Q: Is the AL1008 intercom vandal-proof for use in a prisoner visiting room divided by glass?

Q: What window intercom system is recommended for a cashier window with a hole, requiring clear audio quality?
A: A suitable option is the AL1008 thru-glass intercom with a 12VDC plug-in power supply. Additional choices are available under the window intercom systems category on IntercomsOnline.com, depending on audio needs and installation preferences.

Q: What intercom solution works for a police station with bulletproof glass and brick walls, where wire runs may need to be 30–40 feet?
A: For setups without a window hole, a standard indoor window intercom system can be used, but its included wiring is short and may not support 30–40 ft runs. A better option is the ZT1032 High-Definition Gate Intercom system, which uses CAT-5 wiring and an IP phone inside. The customer was advised that this system can handle longer cable runs, and the maximum supported length would be confirmed via email.

Q: What is the best wired intercom for talking hands-free to a customer outside a window, similar to a bank teller setup?
A: If you can run a wire, the lowest-cost option is the AP1042, which requires push-to-talk for the inside person. The highest-quality option is the ZT1032, which is fully hands-free with noise cancellation. We also have several window intercoms here: Window Intercoms

Q: Do you sell an intercom system with a 48" x 36" service window and a payment pass-through for a government office?
A: Intercoms Online does not sell glass or complete window systems, only intercoms that can be used with glass.

Q: Does the vandal-resistant Window Intercom with AC power (AL1008) have a push-to-talk function?
A: It does not have a push-to-talk button, only an on/off switch. The off switch can be toggled to control communication but is not a true push-to-talk feature.

Q: What intercom system would work for a courthouse office with a 6-inch sliding window opening where it is hard to hear customers?
A: A window intercom like the CT1003 Indoor Window Intercom System would work if wiring can be run under the counter. If replacing the window with a fixed pane and document opening, any window intercom system can be used, with a round hole cut if needed. The AL1008 works in holes.

Q: Is the STS-K080-IP expandable to control more than one lane?
A: No, it only supports a single lane. You could use the ZT1032 and the ZT1008 for multiple lanes.
