- Optional mobile access
- Remote visitor communication
The Akuvox 2-Wire IP Intercom Kit supports a combination of indoor monitor functionality and optional mobile access, allowing buildings to provide modern features without requiring every resident to use the same access method.
How Does the System Integrate With Access Control?
Apartment intercoms often need to work alongside existing door and building access hardware.
The source identifies potential integration with:
- Electric strikes
- Magnetic locks
- Lift access control
- Keypads
- Cards
- Smart access platforms
This allows a building to upgrade intercom functionality while progressively integrating other access control components. The intercom can also form part of a broader Access Control strategy, allowing apartment buildings to coordinate visitor communication, door release and controlled entry.
How Does Central Management Work for Strata Properties?

The source describes IP-based intercom systems as offering stronger security controls than traditional analogue approaches.
2-Wire Retrofit vs Full IP Rewiring: What Is the Difference?
| Factor | 2-Wire IP Retrofit | Full IP Rewiring |
|---|---|---|
| Existing Cabling | Reuses suitable two-core wiring | Requires new network cabling |
| Building Modification | Generally less invasive | Can require more extensive building work |
| Installation Disruption | Potentially lower | Potentially higher |
| Labour Requirements | Can be reduced where existing infrastructure is suitable | Usually greater due to new cabling |
| Project Complexity | Lower when existing wiring is compatible | Higher infrastructure requirements |
| IP Features | Available through compatible 2-wire equipment | Native IP infrastructure |
| Staged Upgrade | Suitable for staged retrofit projects | More suitable when major infrastructure work is planned |
