Product Overview
The Akuvox R20A-2 is a sleek, compact 2-wire IP video intercom engineered to deliver high-definition visual security and seamless access control. Designed specifically for retrofitting existing properties or simplifying new installations, the R20A-2 transmits both power and network data over a single pair of 2-wire cabling, eliminating the need to pull fresh Cat5/6 ethernet lines throughout your facility.
Housed in a durable aluminum alloy body with an IP65 weather-resistance rating, this door station features a 2MP 1080p camera with wide-angle coverage and IR night vision, an integrated dual-frequency RFID card reader (13.56MHz & 125kHz), and SIP 2.0 open protocol support. Whether deployed at apartment entrances, office doors, or commercial gates, it provides dependable two-way communication and remote door unlocking, distributed directly through Total Security Equipment.
