Overview

The Dahua N70 is a 3U, 19-inch rack-mounted video matrix platform for running large video walls in security control rooms. Its nine slots take audio and video cards and can drive up to 18 4K channels, splicing across 36 screens. It suits operators at industrial sites, hospitals and campuses who need one controller for a large wall. Request a quote and we will confirm the card layout.

What the N70 does in a video wall system

The Dahua N70 is a video matrix platform built into a 3U chassis for a standard 19-inch rack. It takes video sources such as camera feeds and workstation outputs, processes them and routes the result to the displays that make up your wall. Its architecture follows the telecom-grade ATCA design, and it runs an embedded Linux system on a 64-bit octa-core processor, which suits a control room that depends on the wall being available during every shift.

Signal capacity, splicing and decoding

The chassis has nine slots. One holds the main control card and eight take audio and video cards, which can be inserted in any slot. This lets you size inputs and outputs to the wall rather than buying more platforms. In its maximum configuration the N70 outputs up to 18 channels of 4K and 18 channels of 1080p over HDMI, and it can splice a single display across up to 36 screens. Scenes can use window splitting, scaling, layering and roaming, so one camera feed can span several panels. The platform also accesses up to 1,024 network channels and decodes up to 432 channels of 1080p video at 25 fps. Supported formats include H.265, H.264, SVAC, MPEG4 and MJPEG.

Control, scenes and integration

Operators can manage the platform from a local interface, a web page, a desktop client, a mobile client or a network keyboard. Up to 128 scenes can be stored, and each scene can have its own layout on the wall. Window splits are available in 1, 4, 6, 8, 9, 16, 25 and 36 layouts, along with custom M × N grids. The default background colour of the wall can be set, subtitles are available, and screens can be switched on and off as needed. The source data lists GB28181, ONVIF, RTSP, Dahua private and Hikvision private protocols, and an SDK is provided for secondary development.

Where the N70 fits in Qatar

Industrial control room: an operations room at a plant in Mesaieed or Ras Laffan showing camera feeds and process screens on one multi-screen wall, with alarm inputs connected to site systems.
Hospital or campus security hub: a monitoring room in Education City or a Doha hospital where operators need camera feeds and presentations on the same wall, with saved scenes for each shift.
Transport or event command room: a centre near Hamad International Airport or a venue in Lusail that shows feeds from many cameras and changes its wall layout for each event.

Planning the rack, power and environment

The N70 is a 3U unit with a net weight listed between 12.29 kg and 13 kg, so plan for two people to lift it into the rack. The input range is 100–127 VAC and 200–240 VAC at 50–60 Hz, which covers Qatar's 240 V, 50 Hz supply. Power consumption is up to 140 W. The source lists a single power supply as included and a dual supply as optional, so decide early whether your site needs redundancy. The stated operating range is –10 °C to +50 °C with 10% to 90% non-condensing humidity. Qatar summers regularly pass 45 °C, so install the unit in an air-conditioned room with airflow around the chassis rather than in a closed cabinet. The data gives two sets of dimensions, so confirm the depth against your rack before ordering.

Send your wall size, number of sources and rack location to SmartRooms Qatar and request a quote. We offer free site surveys, professional installation and delivery to all eight municipalities of Qatar, and quotations are usually issued within one working day.

Questions about N70

Is the Dahua N70 right for a security control room at an industrial site?

Yes, if the room needs one controller to drive a multi-screen wall of camera feeds and process displays. The N70 is a 3U video matrix that takes video sources, processes them and routes them to HDMI displays. Its nine slots, up to 18 channels of 4K output and splicing across 36 screens suit an operations room at a plant in Mesaieed or Ras Laffan. Send your camera count and wall layout to request a quote.

Does the N70 need displays or a video wall to be useful?

It is a controller rather than a screen, so it needs HDMI-connected displays or video wall panels to show its output. The base unit has four HDMI outputs, two HDMI 2.0 and two HDMI 1.3. In a full configuration with additional audio and video cards, output reaches 18 channels of 4K and 18 channels of 1080p. Confirm panel count and input types before ordering so the card layout matches your wall.

How many screens can one N70 splice together?

The platform supports splicing a display across up to 36 screens, which covers a 6 by 6 wall of panels. Window splits include 1, 4, 6, 8, 9, 16, 25 and 36, and custom M × N layouts are available. Windows can be scaled, layered and moved across the wall, so a hospital command room in Doha could show one camera feed across several panels at once.

What video inputs does the N70 accept?

Input capacity depends on the cards you fit. The source data lists up to 8 channels of 4K at 60 Hz or 8 channels of 1080p at 60 fps in maximum configuration, and access to up to 1,024 network channels. The encoding card lists two video inputs, one HDMI 2.0 and one HDMI 1.3, with embedded HDMI audio. Tell us how many cameras and sources you have so we can size the cards.

Which video formats and protocols does it support?

It decodes H.265, H.264, SVAC, MPEG4 and MJPEG video. The data also lists GB28181, ONVIF, RTSP, Dahua private and Hikvision private protocols, with TCP, UDP, RTP, RTSP and RTCP transport. Check that your cameras and encoders use one of these before ordering, especially if your site mixes camera brands.

Can a duty supervisor control the wall from a phone or browser?

Yes. Scenes can be controlled from the local interface, a web page, a desktop client, a mobile client or a network keyboard. At a logistics hub near Hamad International Airport, a supervisor could recall a saved scene from a tablet during a shift handover. Up to 128 scenes can be stored, each with its own wall layout, so different shifts can keep their own standard views.

Will the N70 cope with an unventilated comms room in Al Wakrah in summer?

Not reliably. The stated operating range is –10 °C to +50 °C with 10% to 90% non-condensing humidity, and Qatar summers regularly exceed 45 °C. Install the unit in an air-conditioned room with clear airflow around the chassis. The data mentions intelligent temperature control fans in the cabinet, but these do not replace a cooled room.

Will it run on Qatar's 240 V, 50 Hz power?

The source lists an input of 200–240 VAC at 50–60 Hz, so Qatar's 240 V, 50 Hz mains falls inside the stated range. Power consumption is up to 140 W. The data does not list a plug type, so confirm the power cord and plug fitting for your site with the SmartRooms Qatar team when you request a quote.

Should a monitoring centre in Lusail choose dual power supplies?

The source lists a single power supply as included, with a dual supply as an option, and describes the chassis as suited to locations such as machine rooms. A monitoring centre that cannot tolerate downtime should request the dual power supply option in the quotation. Mention your uptime requirements so the configuration is quoted correctly.

How much rack space does the N70 need?

It is a 3U unit that mounts in a standard 19-inch rack, with a net weight listed between 12.29 kg and 13 kg depending on configuration. The source gives two sets of dimensions, and the depth differs between them, so confirm the depth against your rack. Plan for two people to lift it into place and leave room at the rear for cables to the HDMI outputs and network ports.

Does a campus in Education City need a site survey first?

A site survey helps when the control room has many cable runs from cameras to the platform and from the platform to the wall. SmartRooms Qatar offers free site surveys, where we check rack location, cooling, power outlets and cable routes before installation. For a campus in Education City, this confirms room conditions and the HDMI runs to each panel.

Can a government authority in Doha buy the N70 through a tender?

Yes. SmartRooms Qatar supplies government tenders, including Monaqasat, and accepts purchase orders (LPOs), with payment by bank transfer, cheque or purchase order. Include the model, number of units, wall layout and rack location in your request. Quotations are usually issued within one working day, and products are covered by the manufacturer's warranty.
