Tips for the quick deployment of a 2-wire intercom solution

As we enter the era of AIoT, many existing 2-wire intercom systems fail to meet the growing residents' needs for security and convenience. The 2-wire residential SIP video intercom solution fromAkuvox is perfect for upgrading outdated systems on existing infrastructure. They allow for a:

• Cost reduction through the reuse of existing cables.
• Upgrade of intercom functions.
• Adaptation to projects of different scales.

When it comes to a 2-wire project, the biggest constraint is its deployment.

End users do not want to disrupt their interior decoration to replace devices. As for owners and installers, they must consider the high cost of labor and other expenses associated with redeployment.

So, how can a new installation or replacement of a 2-wire intercom system be implemented at a lower cost? Let's take a look !

Quick selection of devices and power supply

In this guide, we will use the products from the manufacturer Akuvox. The indoor screens are C313W-2 and the intercoms are R20A-2. The "-2" at the end of the reference indicates that these are products belonging to the 2-wire range ofAkuvox. This manufacturer also offers a wide range of IP products (intercoms, access control, monitors, etc).

We may also be required to use an NS-2 Switch or IP intercoms such as the R29, for example.

The NS-2 Switch enables the connection between the 2-wire network and the IP network through its RJ45 port. It also allows powering up to 6 devices. Akuvox 2-wire when connected to a 48V or 24V power supply (we recommend using 48V power supplies).

Note: With a power supply of 48V or 24V, an NS-2 allows you to connect up to 6 devices simultaneously, whereas the C313W-2 can only power 5 devices without an NS-2.

Villa example

It is a 5-room villa, with each room containing a C313W-2. The 48V power supply allows the C313W-2 installed in the living room to power three other C313W-2s and one R20A-2.

An R20A-2 is installed at the entrance for access control and intercom, and several IP cameras in the garden for surveillance.

Thanks to the cloud ofAkuvox, users can answer incoming calls from door entry systems, monitor their home at any time via mobile phone, etc.

Example of a residential building

It is a small apartment building.

Each apartment is equipped with an R20A and a C313W-2 for the home intercom and surveillance.

The NS-2 on each floor, using 48V power supply, connects 3 households to ensure network stability.

The R29 is installed in the entrance hall, allowing users to make calls and control access, thanks to the multiple access control technologies integrated into the R29 (facial recognition, PIN code, QR code, BLE, NFC, RFID, etc).

With the Cloud system, administrators can manage the building remotely, and users can answer incoming calls from the intercom, monitor their home at any time via their mobile phone, etc.

Summary

We have seen here that the deployment of a 2-wire system can sometimes be useful in renovation cases, for example when it comes to modernizing an old installation.

The implementation of an NS-2 allows for the establishment of a hybrid 2-wire IP system, thereby achieving the best of both worlds.
