Product Overview
The Akuvox R20A-2 is a compact, vandal-resistant 2-wire IP video door phone intercom designed to provide secure entry management for residential homes, multi-dwelling apartments, and commercial offices. Equipped with a high-definition 2-megapixel camera delivering a wide 110° horizontal viewing angle and IR night vision, it provides clear video feeds for visitor identification day or night.
Engineered specifically for retrofit installations, the R20A-2 transmits power and data over a single pair of legacy 2-wire cables, bypassing the need to run new Ethernet lines. It features a built-in dual-frequency RFID card reader (13.56MHz with NFC & 125kHz), an IP65 weather-resistant aluminum alloy housing, two-way audio with echo cancellation, and an integrated door release relay. Supplied directly through Total Security Equipment.
