What customers say
Professionals highly value the Atlona OmniStream encoder for its exceptional 4K video quality and robust reliability in critical settings. Integrators consistently praise its low latency, which is vital for live presentations and conferencing. A key strength is its seamless integration within the OmniStream ecosystem, including native Dante audio support. While the enterprise-grade build quality inspires confidence for large deployments, users note that initial setup demands significant network expertise, posing a challenge for less experienced installers. Despite the high price, the superior feature set and long-term stability justify the investment for sophisticated AV over IP applications where performance is paramount.
Know before you buy
No, this encoder is designed to work over standard 1 Gigabit IP networks. It is compatible with off-the-shelf managed Gigabit switches, making it easier to integrate into existing office or facility infrastructure.
The latency is extremely low, measuring at just 0.5 frames, or less than 8ms for 1080p at 60Hz. This makes it suitable for real-time applications where minimal delay is critical.
The AT-OMNI-111 supports resolutions up to 4K/30 4:4:4 and 4K/60 4:2:0. If your workflow requires full 4K/60 4:4:4, you may need to verify your source settings to match these supported specifications.
The encoder features dual Ethernet ports that provide system redundancy. If the primary connection fails, the unit automatically switches to the secondary port to ensure your video feed remains uninterrupted.
Yes, it supports a wide range of high-quality audio formats, including LPCM, Dolby Digital, Dolby TrueHD, and DTS-HD Master Audio, ensuring your audio quality matches your video output.
The AT-OMNI-111 is powered via Power over Ethernet (PoE). This simplifies installation by allowing you to provide both data and power through a single network cable, provided your network switch supports PoE.
