Audio Door Intercom
An Audio Door Intercom System is a voice-based access control solution designed to enhance security and convenience at entry points. It allows two-way voice communication between a visitor at the door and the person inside the building — whether it's a home, apartment, or commercial space — before access is granted.
Audio intercoms are simple, cost-effective, and widely used in locations where visual identification is not critical but controlled entry is essential. They can be wired or wireless, with some models offering integration with electronic door locks for remote unlocking.

Where it works best & how we install it
Placement guidance we follow on site.
For Homes and Apartments
Outdoor Door Station
- Mount at the main gate or front door at about 4.5–5 feet high, for easy microphone and speaker access.
- Weatherproof and vandal-resistant models are recommended for external installation.
Indoor Station
- Place near entryways, kitchens, or bedrooms — locations where users are most likely to respond to a call.
- In multi-level homes, consider adding an intercom on each floor for convenience.
Wiring
- Most wired systems require only 2 or 4 wires (for power and communication).
- Use quality shielded cables to minimize interference.
For Multi-Unit Buildings and Offices
Multi-Tenant Outdoor Panel
- Allows visitors to call specific apartments or office suites.
- Can include directory buttons or keypads for easier navigation.
Centralized or Multiple Indoor Units
- Receptionists, security personnel, or residents can answer calls from different points in the building.
Access Control Integration
- Connect with electronic door strikes or gate controls to enable remote unlocking via the intercom.
Wireless Options
- Use wireless audio intercoms where cabling is not feasible, such as older buildings or temporary setups.
