Akuvox R20BX2 On-Wall 2-Button SIP Video Door Phone

In Kuwait a villa is often shared: the parents on the ground floor, a married son upstairs, one gate for both. The Akuvox R20BX2 gives that gate two labelled call buttons, so a visitor presses the right name and only that family's indoor monitor or mobile rings.

Each button calls its own target: an Akuvox indoor monitor, a SIP phone, a group of devices or the SmartPlus app. The 2MP camera covers 110° × 58° at up to 1080p, and infrared LEDs keep the picture clear at night. A motion sensor wakes the panel as someone approaches.

It has two relays, so either family can open the pedestrian door and, separately, the car gate. The reader takes 125 kHz EM cards and 13.56 MHz Mifare and DESFire cards, and Android phones over NFC, with room for 4,000 users, 1,000 contacts and 20,000 cards. RS485 and Wiegand connect it to access control equipment.

The front is aluminium alloy, IP65, 185 × 85 × 24 mm, powered by one 802.3af PoE cable. This is the on-wall build; the R20B also flush-mounts in a back box. Akuvox makes on-wall and in-wall rain covers for it. If the house later becomes three flats, the R20BX3 has a third button in the same size.
