audio door phone

Description

audio door phone is a simple, wired or wireless intercom system for clear two-way communication between a visitor at the door/gate and occupants inside, featuring an outdoor unit (speaker/mic) and indoor unit (speaker/mic/button) for visitor identification and remote door release, ensuring security and convenience with easy DIY setup and durable designs like aluminum exteriors.

• Durable Outdoor Unit : Often made from anti-oxidation, durable aluminum, suitable for surface or flush mounting near the entrance.
• Easy Installation : Designed for DIY installation, often with simple 2-wire connections for wired models, reducing complexity.
• Visitor Identification : Some models can display names or room numbers on the outdoor unit and have LED indicators.
