Access control, intercom, and visitor management in one device — no separate card reader, intercom panel, or visitor kiosk to wire, power, or integrate.

Palm and face authentication. Liveness detection. Anti-spoofing. Built for real-world conditions.

On-board relays, Wiegand I/O, and OSDP v2.2 give you full door control from a single mount — nothing else required.
Compliant where it counts. NDAA Section 889 approved, IEC EN 60839 Grade 4 certified, designed and engineered in the USA.
Omni connects natively to Cielo365 for cloud-based user management, visitor control, and intercom — no on-site servers required.

Slim Design & Mounting Options

Slim enough for any wall, versatile enough for any install. The Omni20 supports multiple mount types and includes speedgate accessories for high-traffic entry points.

IP66 Water & Dustproof Protection Rating

IP66-certified — built for outdoor deployment without compromise.

Advanced Security

AES-128 encryption protects data on the device and every communication between Omni and the software platform.

Supports Multiple Card Types

No credential left behind. Omni reads 125 kHz and 13.56 MHz across every major card type — EM, IC Card, HID Prox, iCLASS, MIFARE DESFire, Seos, and FeliCa.

Multi-Factor Authentication Capability

Multi-factor authentication across every credential type — palm, face, physical cards, mobile wallet, BLE, QR codes, and PIN. Supports IC Card, DESFire, HID Prox, iCLASS, and Seos, with QR scanning for both visitors and employees.

Video Intercom

Built-in video intercom handles visitor communication directly from the device — two-way audio with echo and noise cancellation for clear conversation in any environment.

Installation Made Easy

Designed for fast, clean installs. Slim profile and flexible mounting options mean less hardware and a cleaner wall. Speedgate accessories available.
