Audio Door Phones for Sale in South Africa: Stockist Guide & Comparison

Overview: What is an Audio Door Phone?

An audio door phone is an electronic intercom device enabling two-way voice communication between a visitor at a building entrance and a resident or staff member inside. These systems offer basic access control, enhancing building security by letting users verify and communicate with visitors before granting entry.

Audio intercoms remain a popular, cost-effective alternative to video door phones, suitable for homes, apartments, offices, schools, and warehouses in South Africa. Typical systems available from Communica include:

• Single-door audio intercoms with wall-mount indoor stations
• Multi-subscriber (multi-apartment/office) setups
• Weatherproof outdoor panels for industrial entrances

Selection Criteria: How to Choose the Right Audio Door Phone

When deciding on an audio door phone system for your property, focus on:

• Cabling: Can you reuse existing lines, or is new cable required? For longer distances in South African settings (e.g., long driveways), confirm maximum supported length per the specification sheet.
• Power Supply: Most basic units run from 12V DC (often available from Communica's wide power supply range), while more advanced systems might need dedicated adapters.
• Weather Resistance: Check for outdoor call panels rated for rain, dust, and vandal exposure relevant to SA's climate.
• Expandability: If future upgrade to video or multi-door support is needed, review appropriate models and accessories.

For both new installations and replacements, Communica offers advice on matching your building's needs to suitable intercom systems and supplies-from call stations and control units to relays, locks, and wiring.

In most residential setups, the outdoor panel connects to the indoor station using 2 or 4 wires (power and audio). A relay output on the outdoor or indoor unit is wired to an electric strike or maglock. For multi-subscriber systems, consider professional installation to handle bus wiring and distribution.
