Videos HIDE

The Armatura Omni line brings touchless access to the door without compromise. Each unit combines palm and face biometrics with 125 kHz and 13.56 MHz card reads, QR codes, and PINs in a single slim housing -- standalone capable or integrated over Wiegand and OSDP V2. PoE power, IP66 weatherproofing, and a built-in video intercom reduce the accessory count and simplify the rough-in.

About the OmniAC20-LHF: This is the slim mullion-mount model with dual-frequency card support. It reads both LF (125 kHz -- EM, HID Prox) and HF (13.56 MHz -- MIFARE Classic, DESFire EV1) credentials, plus BLE and NFC, making it a one-reader solution for sites migrating from legacy badges to modern smart cards. The slim form factor fits mullion and door-edge installs where space is tight.

Built for the commercial installer

  • Multi-tech card reads: LF (125 kHz) and HF (13.56 MHz) in one reader -- no hardware swap when migrating credential formats.
  • BLE and NFC: Mobile credentials extend access options without adding hardware at the door.
  • Palm and face biometrics: Reduces tailgating and eliminates credential sharing at high-security openings.
  • Visitor access: QR codes and PINs cover guests and contractors without card issuance.
  • Standalone or integrated: Full access logic on-device, or tie into an existing panel via Wiegand or OSDP V2.1.7.
  • Video intercom: Two-way video and audio at the door -- no separate intercom system needed.
  • PoE + IP66: Single-cable install, rated for outdoor and harsh environments.
  • Cloud option: Cielo365 adds remote management and reporting for multi-site deployments.

System requirements
