Product Overview

Overview

The Yealink DE300 is a high-performance AV-over-IP decoder that delivers 4K at 60 Hz video with 4:4:4 chroma sampling over a 1 Gbps network, with latency of less than one frame. It has a built-in 2 x 2 video matrix and a video capture output, so the same unit can feed a display and a recording or streaming PC.

It controls displays through RS232, IR and CEC, supports HDCP 2.3, and offers USB over IP with two USB 3.0 Type-A ports for keyboards, mice and other local devices. Paired with an encoder on the same network it pairs automatically, and it works over CAT5e or better up to 100 metres. It is powered by PoE+ or a 12 V DC adapter and installs in a rack, under a desk or flat.
