Atlona AT-OMNI-111 Networked AV Encoder

Atlona AT-OMNI-111 Networked AV Encoder

The Atlona AT-OMNI-111 is a professional-grade networked AV encoder designed for high-performance, low-latency 4K/60 4:4:4 video distribution over standard Gigabit Ethernet networks. Part of the -OmniStream™ platform, it delivers exceptional quality and reliability for large-scale AV over IP systems in enterprise, education, and commercial environments. The OMNI-111 encodes HDMI® sources up to 4K/UHD with embedded audio, HDR, and control pass-through (RS-232 or IR), using the advanced -VCx™ codec for artifact-free performance and ultra-low latency of less than one frame.

Engineered for scalability and efficiency, the OMNI-111 supports -dual simultaneous encoding of 4K/60 4:4:4 and 1080p streams, ideal for multiview applications, overflow rooms, and hybrid streaming setups. With features such as -HDCP 2.2 compliance, -Ethernet link testing, and -Velocity™ Device Manager integration for centralized configuration and management, the OMNI-111 ensures seamless AV network deployment and monitoring. The unit supports -PoE powering and advanced network security standards including -IEEE 802.1x authentication.
