About the Akuvox R20A-2

The Akuvox R20A-2 brings the R20A's metal door station to buildings where only the two cores of an old analogue intercom reach the door. Those two wires carry both its power and its IP connection. In a villa they run straight to an Akuvox C313W-2 two-wire monitor, which Akuvox sells with the R20A-2 as a kit with one power adapter. In a building with several flats they end at an Akuvox NS-2 2-wire IP switch instead, which sits on a DIN rail, runs on 48V DC, serves up to six two-wire devices and joins them to the network through one RJ45 port.

At the door the visitor sees an aluminium alloy panel with one blue-backlit call button. The 2MP camera covers 110° × 58° at up to 1080p and 30 fps, switches to infrared night vision in the dark, and a motion sensor wakes the unit as someone walks up. Residents answer on an Akuvox indoor monitor such as the C313W-2, on SIP phones, or in the SmartPlus app.

It reads 125 kHz EM cards and 13.56 MHz Mifare and DESFire cards, plus Android NFC, and stores 4,000 users and 20,000 cards. Unlike the PoE R20A, the two-wire build has one relay and one input, so it opens one lock or gate; RS485 and Wiegand ports are still there for access control.

It is IP65 rated, 145 × 85 × 22 mm, mounts flush or on the wall, and works from -30 °C to +60 °C.

Akuvox R20A-2 questions

What powers the Akuvox R20A-2?

In a villa, the Akuvox C313W-2 two-wire monitor with its power adapter powers the door phone over the two wires, as in Akuvox's two-wire kit. In a building, an Akuvox NS-2 2-wire switch with a 48V DC supply feeds the door phone and every monitor.

How many door phones and monitors can one NS-2 serve?

Up to six two-wire devices per NS-2, and more NS-2 switches can be cascaded over two-wire cable for bigger buildings.

What is the difference between the R20A-2 and the R20A?

The R20A needs a network cable and PoE and has two relays and two inputs. The R20A-2 runs on two wires and has one relay and one input. The camera, panel and card reader are the same.
