Overview

The Dahua LCH75-MC410-B-S2 is a 75-inch 4K interactive panel running Android 14, with 8 GB RAM, 64 GB storage, dual Wi-Fi 6 and a 48 MP camera. Its infrared touch supports up to 40 points on Windows, and its array picks up voices from 8 m to 12 m. Suited to classrooms, meeting rooms and training spaces in Qatar that need one panel for presenting, calls and collaboration.

A 75-inch panel that runs its own Android 14 system

The Dahua LCH75-MC410-B-S2 belongs to the MC410-B-S2 Business Series. It pairs a 3840 × 2160 display with an Android 14 system, so a teacher or presenter can open apps, browse and annotate without a separate computer. An external module running Windows can also be connected, with Windows 7, 8, 10 and 11 listed as supported systems.

Display, touch and sound figures that matter

The IPS LCD uses DLED backlighting, with a typical brightness of 350 cd/m² and a typical static contrast ratio of 1,200:1. It runs at 60 Hz in a 16:9 format, and its rated lifespan is 50,000 hours or more. The infrared touch layer sits behind 3.2 mm anti-dazzle tempered glass rated at 9H or harder, and it records up to 32 touch points on Android and 40 on Windows. You can write with a finger or with the supplied pen, which attaches magnetically to the frame.

Camera: 48 MP photo and 4 MP video on Android, with an 88° diagonal field of view.
Microphone: an array with 8 m to 12 m pickup, echo cancellation and noise filtering.
Speakers: two built-in speakers rated at 15 W each.

Where it fits in Qatar

In a private school in Al Wakrah fitting out new classrooms, a 75-inch panel suits a standard room or small lecture hall, where students in the back row still need to read what is written on the screen. In a meeting room in West Bay or Msheireb, the built-in camera and microphone allow a team to hold a video call with colleagues abroad from the same screen, using a connection that offers both station and access point modes over Wi-Fi 6. A corporate training room in Lusail or a clinic conference room in Doha are other realistic settings for this size.

What to plan before installation

The panel measures 1,707.6 mm long, 115.7 mm deep and 1,038.5 mm high, and weighs 50 kg net or 58.4 kg packed. The wall mount uses holes spaced 600 mm by 400 mm, and a mobile bracket is also listed as an installation option. Because of the weight, check the wall or stand before fixing it. The power supply accepts 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V mains, and draws 141.5 W typical and 270 W at maximum. The operating range is 0 °C to +40 °C, so the panel belongs in an air-conditioned room. Summer temperatures outdoors in Qatar can exceed 45 °C, so confirm the room's cooling and location with the SmartRooms Qatar team before installation.

Questions about LCH75-MC410-B-S2

Who is the LCH75-MC410-B-S2 designed for?

It suits organisations that want one large screen for presenting, annotating and video calls without a separate computer. Its Android 14 system runs apps directly, and the 75-inch 4K display works well in rooms where roughly a dozen to twenty people sit in front of the screen. It is a Business Series model, so it is aimed at schools, government offices and companies rather than home use.

Is a 75-inch panel the right size for a classroom in Qatar?

For a standard classroom or small lecture room, 75 inches usually keeps text and diagrams readable from the back row, although the right size depends on room length and seating. A private school in Al Wakrah fitting out new classrooms can use the 3840 × 2160 resolution and 16:9 format to show detailed lesson material. Confirm the layout and viewing distance during a free site survey before ordering.

Can I connect a Windows PC to this panel?

Yes, through an external module. Windows 7, 8, 10 and 11 are listed as supported systems for that module. For other sources, the panel has two HDMI 2.0 inputs supporting 4K at 60 Hz, plus USB ports and an RJ-45 network port at the rear. Confirm the exact module and cable set with the SmartRooms Qatar team when you request a quote.

How does the touch screen work and how many touch points does it support?

It uses infrared touch, with the touch layer attached without lamination. Android supports 32 touch points and Windows supports 40. The 3.2 mm anti-dazzle tempered glass has a hardness of 9H or more, which helps it resist scratches and glare in bright rooms. You can write with a finger or the supplied pen, which attaches magnetically to the frame.

Can the built-in camera and microphone handle video calls with colleagues abroad?

The Android camera offers 48 MP photo and 4 MP video with an 88 degree diagonal field of view, and the microphone array picks up voices from 8 m to 12 m away. Echo cancellation, automatic gain control and noise filtering are included. For a meeting in West Bay that connects Doha with teams abroad, this can reduce the need for a separate conferencing camera in a small room. Check sightlines during the site survey.

Can it be placed in an unshaded lobby or next to a sun-facing window?

Install it in an air-conditioned room. The operating temperature range is 0 °C to +40 °C, with humidity between 10% and 90% non-condensing. Outdoor summer temperatures in Qatar can exceed 45 °C, and dust storms are common, so the panel should be kept away from direct sun and dust. Ask the SmartRooms Qatar team to review the room during the free site survey.

Does the power supply work with Qatar's electricity?

The power supply is rated 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Consumption is 141.5 W typical and 270 W maximum, and standby draws no more than 0.5 W. Ask SmartRooms Qatar to confirm the plug type of the supplied power cord against the BS 1363 (Type G) sockets in your room, and plan a dedicated outlet for each panel.

What comes in the box?

The packing list includes the interactive panel, a wireless plug-in module, a power cord, two stylus pens, a remote control, a wall mount bracket, a quick start guide, legal and regulatory information and an accessory package. Wall mounting and a mobile bracket are the listed installation options, so confirm with us whether a mobile bracket is included in your quotation.

How much wall space and load capacity do I need?

The panel measures 1,707.6 mm long, 115.7 mm deep and 1,038.5 mm high, and weighs 50 kg net or 58.4 kg packed. The wall mount holes are spaced 600 mm by 400 mm. Because the panel is heavy, check that the wall or stand can carry the load before fixing it. A free site survey lets us assess wall construction, height and viewing distance before the quotation.

Does it support Wi-Fi and Bluetooth for wireless devices?

Yes. The Wi-Fi module works as both a station and an access point, using 802.11 a/b/g/n/ac/ax, which is the Wi-Fi 6 standard. Bluetooth 5.2 is supported across BR/EDR and BLE, operating in the 2.4 GHz band. The two Wi-Fi roles let the panel join your network and also host a direct connection for presenters, which helps in rooms with limited cabling.

Can a school or government entity buy this through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including those published on Monaqasat, and payment can be made by bank transfer, cheque or purchase order. The product is covered by the manufacturer's warranty. For a school ordering several classroom panels, list the quantity, room locations and mounting type in your request so the quotation covers the full job.

Would it suit a training room in Lusail or a clinic conference room in Doha?

Yes, for a training or conference room of moderate size where attendees sit close enough to read slides and annotate. Its Android system can open presentation apps directly, and two HDMI inputs take laptop or workstation sources. Check the room for window glare, since the anti-dazzle glass helps and reducing direct sunlight on the screen helps further. Request a quote and send us the room dimensions.
