Overview
The Armatura OmniAC20-W[RNP] is a compact door terminal that opens a door by face or palm, with cards and QR codes as a fallback for visitors and contractors. A dual camera and on-board AI processor do the matching on the terminal, and the IP66 housing lets it stand outdoors as well as inside.
This version is fitted with the [RNP] card module.
Is it right for you?
- Suits clinics, schools and co-working spaces, where touchless face or palm entry avoids shared keypads and lost cards matter less.
- It controls one door. For several doors managed together, pair terminals with an Armatura AHDU controller.
- It needs its own 12 to 24 V DC supply, since it has no PoE input. If you want PoE, see the OmniAC30.
- Choose this version when your existing cards match the [RNP] card module. If you want phone credentials, choose the RNPB or RNIB version.
Key features
- Face recognition in under 100 ms and palm recognition in under 140 ms, each with liveness detection, plus mask detection.
- Face recognition from 40 to 140 cm with dual camera liveness, or 40 to 200 cm with single camera liveness; palm recognition from 18 to 40 cm.
- 50,000 users as standard (100,000 optional), with 10,000 faces and 5,000 palms for 1:N matching (50,000 faces and 20,000 palms in 1:1 mode).
- Reads 125 kHz and 13.56 MHz cards (ISO 14443 A and B, JIS X6319, ISO 15693) at up to 50 mm and scans Armatura ID and static QR codes. Bluetooth phone credentials need the RNPB or RNIB version.
- 2.4 inch touchscreen (240 x 320), speaker and microphone, and SIP v2.0 video intercom.
- 3 relays (1 A at 30 V DC), Wiegand in and out, exit button, door sensor and four auxiliary inputs, and OSDP RS-485 for one extra reader.
- 10/100 Ethernet and Wi-Fi, with TLS 1.2 to the server and AES128 to OSDP readers and panels.
- 1,000,000 event records, 99 access groups, magnetic tamper detection and IP66 weather protection.
What else you need
A 12 to 24 V DC supply (12 V DC at 3 A or 24 V DC at 1.5 A, 10 W maximum), since there is no PoE input.
An electric lock, a lock power supply and an exit button, plus a door sensor (door position sensor) if you want door held or forced alarms.
A network connection by Ethernet or Wi-Fi if you want to manage it from a server or use the video intercom.
Installation
An access control installer should fit it. Mount it at about 1.4 m with the tilted plate, or 1.5 m with the flat plate, for good face and palm angles. The job involves wiring the DC supply, lock, exit button and door sensor, connecting the network, and enrolling users.
Software and licences
Works as a standalone terminal, and can pass credentials to an Armatura AHDU controller or a third-party panel over Wiegand. The Armatura ID app provides QR codes; Bluetooth phone credentials need the RNPB or RNIB version.
Before you buy
- Card support depends on the [RNP] module, so tell us the card technology you use.
- It controls one door and has no PoE input.
