Overview

The Dahua LPH75-MC420-C-S2 is a 75-inch smart interactive whiteboard from the MC420 Business Series. It pairs a 4K panel with infrared touch that accepts finger and magnetic pen input, an Android 14 system with 8 GB RAM, a camera with 9x digital zoom and auto framing, and an eight-array microphone system reaching 8 to 12 metres. It suits meeting rooms and classrooms in Qatar that run hybrid sessions.

A 75-inch Business whiteboard for hybrid meetings

The Dahua LPH75-MC420-C-S2 is a 75-inch smart interactive whiteboard from the MC420 Business Series. Its 3840 × 2160 LCD panel uses DLED backlighting and offers 400 cd/m² typical brightness, a 1,200:1 typical static contrast ratio and 178° viewing angles, so content stays readable from across a room. The panel is rated for at least 50,000 hours of lifespan.

Inside the casing is an Android 14 system running on a quad-core A73 and quad-core A53 processor, with 8 GB RAM and 64 GB storage. Routine sessions can start on the board itself without first connecting a laptop. The front is protected by 3.2 mm anti-dazzle tempered glass with a surface hardness of 9H or more.

Camera, microphones and speakers for remote participants

The built-in camera offers up to 9x digital zoom with a 99° diagonal field of view, and includes face detection, auto white balance, voice tracking and auto framing. The eight-array microphone system picks up voices from 8 to 12 metres, with echo cancellation, automatic gain control and intelligent noise filtering. Two 20 W speakers provide the room audio.

Connectivity for laptops, sources and networks

Video in: two HDMI 2.0 inputs at 4K 60 Hz, plus a Type-C port carrying DisplayPort 4K at 60 fps, USB data and 5 W charging.
Video and audio out: one HDMI 2.0 output at 4K 60 Hz, a 3.5 mm line out and an SPDIF port.
Network and wireless: two RJ-45 ports, dual-band 2.4 GHz and 5 GHz Wi-Fi that can run a hotspot at the same time, Bluetooth 5.2 and NFC.
Peripherals: four USB 3.2 Gen1 Type-A ports, one RS-232 DB9 port and an IrDA port.

Where it fits in Qatar

A secondary classroom in Al Wakrah or Al Rayyan can use the panel for interactive lessons, with remote students following along through the camera and microphones. A consultancy office in West Bay that holds calls with teams abroad can rely on the camera framing and the microphones' 8 to 12 metre pickup for participants spread across a table. A government department in Doha setting up a boardroom can limit use to registered staff, since the NFC feature can bind up to 10 cards.

What to plan before installation

At 50 kg net and 71.2 kg gross, the board needs a wall built to carry its weight and at least two people to lift it. The rear mounting holes are 600 × 400 mm, and the package includes a wall mount bracket and screw kit. A mobile bracket is available as an alternative installation option. Overall size is 1,707.5 × 87 × 1,067 mm, so measure the wall and the access route. The power supply accepts 100 to 240 VAC at 50/60 Hz and draws 225 W typically, up to 326 W at maximum. The operating range is 0 to 40 °C, so install it in an air-conditioned room away from direct sun and windows, and confirm the environment with the SmartRooms Qatar team before ordering.

The box includes two stylus pens, a remote control, a power cord and a wireless plug-in module. Deephub Meeting software comes free with the unit, but the collaboration function is not included in that bundle, so confirm your software needs when you request a quote.

SmartRooms Qatar supplies the board, delivers it to all eight municipalities of Qatar and arranges professional installation after a free site survey. Purchase orders (LPOs) and government tenders are welcome. Request a quote with your room size, mounting wall and quantity, and our team will reply with a quotation, usually within one working day.

Questions about LPH75-MC420-C-S2

Who is the Dahua LPH75-MC420-C-S2 designed for?

It suits teams that run meetings, lessons and presentations from one large screen. The 75-inch 4K panel fits medium to large meeting rooms and classrooms, while the Android 14 system, camera and eight-array microphones let remote participants join sessions directly from the board. It belongs to Dahua's MC420 Business Series, so it is built around shared workspaces rather than single-user desks.

What operating system does it run, and can I connect a Windows PC?

The board runs Android 14 on a quad-core A73 and quad-core A53 processor with 8 GB RAM and 64 GB storage. The source data lists an external module that supports Windows 7, 8, 10 and 11 as well as Android. Deephub Meeting software is free, but collaboration functions are not included in that bundle, so ask the SmartRooms Qatar team to confirm your software plan before ordering.

What touch technology does it use, and how many touch points does it support?

It uses infrared touch with a response time of 3.3 ms or less and a touch resolution of 32,767 × 32,767. It supports 32 touch points on Android and 50 on Windows, plus 10 simultaneous writing points over more than 90% of the touch area. Writing works with a finger or the included stylus, which attaches magnetically to the frame.

How far can the microphones pick up voices in a room?

The eight-array microphone system picks up sound from 8 to 12 metres, or 26.25 to 39.37 feet. It includes echo cancellation, automatic gain control and intelligent noise filtering. This suits a lecture hall or meeting room where presenters move around. Combined with voice tracking and auto framing, remote participants can see the active speaker without anyone adjusting the camera.

How many video inputs does it have for a laptop and a second source?

It has two HDMI 2.0 inputs supporting 4K at 60 Hz, one HDMI 2.0 output, and a Type-C port that accepts DisplayPort 4K at 60 fps alongside USB data and 5 W charging. That lets a presenter connect a laptop and a second source, such as a document camera or a visualiser, to the same board.

Can it be installed in an unair-conditioned space or outdoors in Qatar?

No. The operating temperature range is 0 to 40 °C, with humidity from 10% to 90% non-condensing. Summer temperatures in Qatar regularly exceed 45 °C and dust storms are common, so install the board in an air-conditioned room away from windows that receive direct sun and from dusty entrances or lobbies.

Does it work with Qatar's 240 V power supply?

Yes. The power supply is rated 100 to 240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. The panel draws 225 W typically and up to 326 W at maximum, and standby consumption is 0.5 W or less. Ask the SmartRooms Qatar team to check the plug type and socket position against the supplied power cord before installation.

What wall space and structure do I need to mount it?

The unit measures 1,707.5 × 87 × 1,067 mm and weighs 50 kg net, or 71.2 kg in packaging. The rear mounting holes are 600 × 400 mm. Confirm the wall can carry the load before fitting. A free site survey from SmartRooms Qatar checks the wall, sight lines and access route, and a mobile bracket is available as an alternative installation option.

Is it suitable for a school in Al Wakrah or Al Rayyan fitting out classrooms?

Yes, for standard and medium-sized classrooms and labs. The 4K panel supports interactive lessons, and the camera and microphones let remote students follow the lesson. If a school is fitting out several rooms, request one quotation covering every unit. SmartRooms Qatar accepts purchase orders (LPOs), which simplifies approval for multi-room school orders.

What should a consultancy office in West Bay check before buying?

Check that the room suits the camera's 99° diagonal field of view and the microphones' 8 to 12 metre pickup, since these determine how many people a table can seat in view. Also check the wall and the network, because the board has two RJ-45 ports and dual-band Wi-Fi. A site survey helps confirm placement for calls with teams abroad.

Can a government ministry or authority buy this through a tender or LPO?

Yes. SmartRooms Qatar supplies government ministries and authorities and handles purchase orders (LPOs) and government tenders, including tenders published through Monaqasat. Send the tender reference and quantity with your request for a quotation. Quotations are usually issued within one working day, and payment can be made by bank transfer, cheque or purchase order.

Does it support NFC card access, and how many cards can it hold?

Yes. The board supports card swiping with NFC and binding of up to 10 cards, and it can also be unlocked quickly via NFC. This is useful in a boardroom where only registered staff should switch the display on. Bluetooth 5.2 and dual-band Wi-Fi are also built in for connecting devices.
