NVD0405DU-2I-8K

What the NVD0405DU-2I-8K does in a video wall system

The Dahua NVD0405DU-2I-8K is a 1U network video decoder. It takes IP video streams and sends them to displays, so an operator can see camera feeds, recorded footage or other network sources on a wall of screens without a PC on every panel. Its headline capacity is two channels of 8K real-time decoding, and its four HDMI 2.0 outputs each carry up to 4K at 60fps.

Specifications that decide whether it fits your project

Four groups of facts matter most when specifying this unit:

• Decoding capacity: the datasheet lists 2 channels at 32MP, 7 at 12MP, 10 at 8MP, 14 at 6MP, 36 at 1080P and 144 at D1, with PAL at 1 to 25fps and NTSC at 1 to 30fps.
• Inputs: one HDMI 2.0 input and one HDMI 1.4 input, with the HDMI 2.0 input accepting up to 4K at 60fps.
• Outputs and splicing: four HDMI 2.0 outputs, splicing up to 8K, and support for up to four video wall units or monitors, with zoom, merge, roam and overlay control.
• Control and I/O: one RJ45 network port at 10/100/1000M, two RS232 ports, one RS485 port, and eight alarm inputs and eight alarm outputs.

Layout options include 1, 4, 6, 8, 9, 16, 25 and 36 splits plus free split, and a fisheye dewarp function for ceiling, wall or ground mounted cameras. Supported video formats are H.265+, H.265, H.264, MJPEG, MPEG2 and MPEG4, with PCM, G.711 and AAC audio. A single 3.5mm audio output and a 3.5mm bi-directional talk pair are also fitted.

Where it fits in Qatar

A security operations room in West Bay, where a wall of four displays needs to show selected cameras from several buildings, is a typical match. The alarm inputs and outputs let the decoder respond to external events, which suits a control room that monitors perimeter or access alarms.

A campus control room in Education City monitoring lab, library and entrance feeds can use the four HDMI outputs for a compact wall. An industrial control room in Mesaieed, where RS485 and RS232 links connect to existing site equipment, can use the serial ports for integration.

Planning power, heat and rack space

The unit runs on DC12V at 5A, with power consumption of 60W or less. Its working temperature range is -10 °C to +55 °C with 10% to 95% humidity. Qatar summers regularly pass 45 °C, so the decoder should sit in a ventilated, air-conditioned rack or room with airflow planned during design. It measures 440 × 322.25 × 44 mm and weighs 3.2 to 3.5 kg. Confirm rack depth, cable routing and the power supply arrangement before ordering.
