For professionals
HAGO Counter Intercoms and accessories
Your trusted partner in clear, reliable, and hassle-free communication – so you can focus on your job

For professionals
Clear conversation through glass – simple for staff, straightforward for installers
For users at the counter
A window or screen keeps staff safe, but it also blocks the voice. People raise their voice, lean towards the gap or have to repeat themselves. The LKS carries speech through the barrier at a natural volume, so staff and visitor can talk normally while looking each other in the eye. Volume is set separately for each side, hands-free (duplex) or push-to-talk (simplex).
For installers
One system, four modules: control unit, window unit, power adapter and connection box. Labelled connections and clear wiring diagrams, so a new installation or a single replacement is straightforward.
Proven at the counter since 1999
The LKS was developed in 1999 for the ticket counters of Dutch Railways and is now used worldwide, including in medical imaging systems in hospitals. With its range of window units and accessories it fits almost any counter, including:
- Fuel stations and ticket counters
- Reception and information desks
- Museums, theaters, amusement parks
- Embassies and government buildings
- Hospitals, scan rooms, pharmacies
- Banks, prisons, high-security areas
