Speed/Window Digital Duplex Interphone/High Definition Window Interphone/Analog Window Interphone

1. Thick space aluminum alloy is used as its shell to avoid the phenomenon of box resonance. Professional acoustic design ensures high fidelity sound quality at the level of a speaker, with clear and realistic sound.

2. Implement bidirectional fully automatic switching of voice communication Adopting professional and unique technology with excellent quality requirements Enable optimal voice communication between tellers and customers.

3. The unique audio automatic switching circuit and automatic noise cancellation circuit achieve automatic channel control and noise suppression, fundamentally preventing the phenomenon of self-excited noise caused by acoustics and electricity. It ensures that the walkie talkie can work stably for a long time in any environment with certain sound insulation between the main and auxiliary units.

4. Provide uninterrupted recording signals As long as you don't unplug the power plug of the machine Whether it's turning down the volume to the minimum Even if the power switch is turned off, the walkie talkie can continuously output recording signals of the same size. This signal source can be connected to the monitoring system for supporting use.

5. High sensitivity pickup range. As long as the straight-line distance between you and the machine is within 50cm, your voice signal can be fully picked up and transmitted to the other party.

6. The unique circuit and design allow only one party to speak at the same time, and the other party who speaks later will not be allowed to have an intercom, ensuring that both parties can hear each other's meaning clearly and avoiding unnecessary trouble
