DE300

What the Yealink DE300 does in a room

The Yealink DE300 is an AV over IP decoder. It receives a video signal that has been sent across an Ethernet network and passes it to a display, recorder or PC at the far end. Instead of running long HDMI cables between floors or buildings, you carry the signal over structured network cabling. This suits multi-storey schools, government offices and campuses in Doha, where the source equipment and the screen are often in different rooms.

Picture quality and latency

The decoder handles up to 4K@60Hz with 4:4:4 chroma sampling and 8-bit colour depth, so fine text, charts and graphics stay crisp on large screens. Latency is less than one frame, which the product overview quotes as 16ms. Advanced HDR appears in its specifications. For live presentations between a Doha office and colleagues abroad, that low delay keeps the picture close to real time.

Switching, capture and control

• 2×2 video matrix: flexible switching between sources and outputs for a dynamic setup.
• USB 3.0 capture output: sends audio and video to a PC, or to an MTR Core room system as a secondary stream.
• Display control: RS232, IR and CEC for power and volume on TVs and other devices.
• USB ports: two USB 3.0 Type-A ports for local keyboard and mouse, plus USB over IP for remote device control.

HDCP 2.3 support allows encrypted UHD content to pass securely, which matters when protected media is shown in a government or corporate meeting room.

Network, power and environment

The DE300 is built for Gigabit networks and reaches 100 meters over CAT5e and above. It can be powered over PoE+ (802.3at, class 4) or with the supplied 12V/2A adapter. Average consumption is 8 W, with 8.5 W peak and 5.4 W in standby. When the encoder and decoder share the same local network, they discover and pair automatically, which keeps commissioning simple.

Operating temperature is -10 to +45°C at 10 to 95% humidity. Qatar summers can push ambient and enclosed cabinet temperatures past that range, so plan an air-conditioned comms room or a ventilated rack, and confirm the location with the SmartRooms Qatar team before fixing.

Where it fits in Qatar

• A government ministry in West Bay linking a boardroom on one floor to a presentation source in a control room on another floor, with the decoder racked in the comms cabinet.
• A university lecture hall in Education City that switches its display between the lecture source and a PC capture feed for recording.
• A corporate office in Lusail connecting a central meeting room to a screen in the reception area, with CEC handling display power.

Planning your installation

The package includes a 1.8 m HDMI cable, two 2.5 m USB 3.0 Type-B to Type-A cables, a 1.0 m USB-C to Type-A management cable, an infrared emitter, Phoenix connectors, a mounting kit, three cable lockers, a 12V/2A power adapter and a quick start guide. Mounting options are rack, under-desk or flat. The unit measures 216 × 160 × 36 mm and weighs 1.24 kg. Plan the rack space or shelf, check that switch ports support gigabit PoE+ if you use it, and map the RS232 or IR cable route to each display.
