Atlona AT-OMNI-111-WP Single-Channel OmniStream 111 WP HDMI AV Encoder Wall Plate

Product Overview

The Atlona AT-OMNI-111-WP is a single-channel OmniStream AVoIP encoder in a US two-gang wall plate form factor, designed for distributing 4K/UHD HDMI sources over standard Gigabit Ethernet networks. Part of Atlona's OmniStream AV over IP platform, this wall plate encoder encodes HDMI signals up to 4K/UHD with HDR support and streams them as IP multicast to one or multiple OmniStream decoders anywhere on the network. AV professionals specifying a 4K AVoIP wall plate encoder or an HDMI over IP wall plate transmitter for commercial installs will find the AT-OMNI-111-WP delivers the artifact-free video quality, ultra-low latency, and enterprise network security features required for scalable pro AV deployments.

Product Description

The Atlona AT-OMNI-111-WP is a networked AV encoder for HDMI sources up to 4K/UHD and HDR, housed in a US two-gang wall plate enclosure with interchangeable black and white trim kits. It is powered by Atlona's advanced VCx codec, which delivers artifact-free presentation of computer-generated content and fast-motion video at encode-to-decode latency under one frame. The wall plate form factor installs discreetly on any standard two-gang wall opening, in furniture, or in floor boxes, providing a clean AV connection point for presenters wherever it is placed. HDR support includes HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision at up to 60 Hz and 12-bit color. The integrated high-performance scaler handles upscaling and downscaling across a broad range of 4K/UHD, HD, and VESA resolutions. Power is delivered via IEEE 802.3af Power over Ethernet from any standard PoE-capable network switch, eliminating the need for a local AC outlet. OmniStream's architecture allows any number of AT-OMNI-111-WP encoders to stream simultaneously to any number of AT-OMNI-121 or AT-OMNI-521 decoders over a standard Gigabit Ethernet network, enabling virtually unlimited system scale. The AT-OMNI-111-WP supports SMPTE-standard FEC (Forward Error Correction) for network error resilience, AES-128 content encryption, and IEEE 802.1x network authentication for enterprise security compliance. Encoded video stream thumbnails can be previewed on a Velocity touch panel or decoder web GUI before source selection. Ethernet link testing is built in for quick infrastructure verification without requiring visual confirmation at each display location. The AT-OMNI-111-WP is managed via a standalone web GUI or centrally through Atlona Velocity Device Manager, which provides automatic device discovery, virtual AV routing, firmware management, and system monitoring across an entire facility. Note that this product has limited availability; a product lifecycle update is forthcoming.

Key Features

• VCx Codec — Artifact-Free 4K/UHD — Proprietary VCx compression delivers pristine image quality for computer-generated content and fast-motion video at latency under one frame between encoder and decoder.
• US Two-Gang Wall Plate Enclosure — Installs in standard two-gang wall openings with interchangeable black and white wallplates and faceplates for a clean, discreet appearance.
• 4K/UHD with Full HDR Support — Supports HDR10 at 10-bit, HLG for 60p broadcast, and Dolby Vision at 12-bit, all at up to 60 Hz.
• PoE-Powered (IEEE 802.3af) — Network switch provides power over the Ethernet cable, eliminating local AC wiring at the wall plate location.
• Ultra-Fast Stream Switching — Switches between video streams up to 4K/60 from OmniStream encoders in under half a second, even across streams at different resolutions and frame rates.
• Configurable Bit Rate up to 900 Mbps — Allows quality tuning to match available network bandwidth and application requirements.
• AES-128 Encryption — Scrambles IP streams for secure content distribution in government, military, and enterprise environments.
• IEEE 802.1x Network Authentication — Meets IT security requirements for authenticated network access using PEAP/MSCHAPv2 or EAP-TLS.
• FEC (Forward Error Correction) — Compensates for AV packet losses in large, multi-switch enterprise networks for consistent, reliable performance.
• Encoder Grouping — Assigns up to eight encoders to a logical group, allowing a decoder to automatically switch between encoders upon input detection.
• Thumbnail Preview — View encoded streams as thumbnails on a Velocity touch panel or decoder web GUI for source verification before display selection.
• AES67 Audio Streaming — Delivers native OmniStream RTP audio alongside AES67-compatible streams supporting multi-channel PCM up to 7.1 channels.
• TAA and NDAA-889 Compliant — Meets federal procurement requirements for government and education installations.

Typical Applications

• Corporate and enterprise campuses requiring scalable HDMI over IP distribution to conference rooms, break rooms, and common areas
• University campuses distributing AV content between buildings and across large LANs
• Meeting rooms and conference centers using OmniStream for flexible, software-managed AV routing without a dedicated matrix switcher
• Houses of worship and performing arts centers requiring ultra-low latency IMAG distribution for large-screen projection
• Digital signage networks distributing content to multiple displays simultaneously via IP multicast
• Government and military installations requiring AES-128 encrypted AV distribution with IEEE 802.1x network authentication
• Divisible rooms and multi-room facilities where room configuration changes require flexible AV source reassignment

Frequently Asked Questions

Q: What network switch is required for the AT-OMNI-111-WP?

The AT-OMNI-111-WP requires a managed Gigabit Ethernet switch with IGMP snooping enabled for multicast control. Atlona publishes a list of Atlona Certified Switch configurations for popular Cisco and NETGEAR models that simplify setup. Atlona also offers NETGEAR switches directly for US and Canada installations.

Q: How is the AT-OMNI-111-WP powered?

The wall plate encoder is powered via IEEE 802.3af Power over Ethernet (PoE) from a PoE-capable network switch. No external power supply or local AC outlet is required at the wall plate location. Maximum power consumption is 12 W.

Q: What decoders are compatible with the AT-OMNI-111-WP?

The AT-OMNI-111-WP is compatible with the AT-OMNI-121 single-channel decoder and the AT-OMNI-521 decoder. The AT-OMNI-121 also supports multiview processing, ingesting streams from up to four AT-OMNI-111 encoders for simultaneous display on a single screen.

Q: Does the AT-OMNI-111-WP support 4K 60Hz video?

Yes, but with a thermal constraint: 4K/60 and 4K/50 resolutions require the input source to provide 4:2:0 chroma subsampling due to the wall plate's thermal envelope. Full 4K/60 4:4:4 is supported by the rack-mount AT-OMNI-111 encoder which has active cooling with independent dual encoding engines.

Q: Can I stream to multiple displays simultaneously from one AT-OMNI-111-WP?

Yes. OmniStream uses IP multicast, which means a single encoder stream can be received by any number of decoders on the network simultaneously without additional load on the encoder or degradation in video quality.

Q: Is the AT-OMNI-111-WP still available for purchase?

The AT-OMNI-111-WP currently has limited availability. A product lifecycle update is forthcoming from Atlona. Contact Creation Networks at creationnetworks.net for current stock status, lead times, and successor product recommendations.

Q: What certifications are required to receive Atlona technical support for OmniStream?

Atlona requires dealers in North and Latin America to complete the Authorized OmniStream AV over IP certification course before accessing advanced technical support. This free online course is available through Atlona Academy at atlona.com/training.

Q: Where can I purchase the AT-OMNI-111-WP?
