What the Dahua LPH86-MC420-C-S2 brings together

The Dahua LPH86-MC420-C-S2 combines a large 4K display, an infrared touch layer, a camera, a microphone array and speakers with an Android 14 computer. A room does not need a separate PC, camera and speakerphone to run a lesson or a video meeting. It belongs to the MC420 Series within Dahua's Business Series.

Display and touch figures that matter in a room

The 86-inch LCD runs at 3840 × 2160 in a 16:9 format, with a DLED backlight, 400 cd/m² typical brightness and a 1,200:1 typical static contrast ratio. Viewing angles of 178 degrees horizontally and vertically keep content readable from side seats. The 60 Hz refresh rate and 8 ms typical response time suit slides and video, and the panel is rated for at least 50,000 hours.

Touch is infrared with a response time of 3.3 ms or less, protected by 3.2 mm anti-dazzle tempered glass rated 9H or harder. The source lists 32 touch points on Android and 50 on Windows, with up to 10 writing points at once over more than 90% of the surface. Finger and pen input both work, and the two styluses in the box attach magnetically.

Android 14 system and connectivity

The built-in system runs Android 14 on a quad-core A73 and quad-core A53 processor, with 8 GB RAM, 64 GB storage and an ARM Mali-G52 MP8 graphics unit. Windows laptops connect through the external module, which supports Windows 7, 8, 10 and 11. Ports include two HDMI 2.0 inputs, one of them on the front, an HDMI 2.0 output, a USB-C input carrying 4K DisplayPort at 60 fps with touch and 5 W charging, four USB 3.2 Gen1 Type-A ports and two RJ-45 network ports. Dual-band Wi-Fi supports 802.11ax and can run a hotspot at the same time. Bluetooth 5.2 and NFC unlocking are also included, and the NFC reader binds up to 10 cards.

Camera, microphones and speakers

Eight microphones pick up speech from up to 12 metres, with automatic gain control, echo cancellation and intelligent noise filtering, so people at the far end of a long room are heard clearly. The camera offers face detection, auto white balance and up to 9x digital zoom, and the listed AI features include voice tracking and auto framing. Two 20 W speakers provide playback, with a 3.5 mm line out and an S/PDIF port for a larger audio system.

Where it fits in Qatar

A private school in Al Wakrah fitting out a new science room can replace a projector, a board and separate speakers with one screen, and the 4K panel suits diagrams and bilingual lessons.

A ministry boardroom in West Bay that regularly meets colleagues abroad can rely on the built-in camera and microphones, so the remote team sees and hears the whole table without extra equipment.

A training centre in Msheireb running workshops for groups can connect a laptop by HDMI or USB-C and annotate on the glass during sessions.

Planning the installation

The unit measures 1,953.5 mm by 1,206 mm, is 87 mm deep and weighs 65 kg net (88.9 kg gross). Wall-mount holes are 800 mm by 400 mm apart, and the box includes a wall mount bracket and screw package. The source also lists a mobile bracket as an installation option. Because of its weight, SmartRooms Qatar carries out a free site survey to check the wall, mounting height and access before installation.

The power supply accepts 100 to 240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 318 W and maximum 453 W, with standby at 0.5 W or less. The operating range is 0 °C to +40 °C, so install it in an air-conditioned room away from direct sunlight and window glare.

Questions about LPH86-MC420-C-S2

What is the Dahua LPH86-MC420-C-S2 used for?

It is an 86-inch 4K interactive whiteboard that runs Android 14, so presentations, annotation and video meetings happen on one unit. The built-in camera, eight-microphone array and two 20 W speakers mean a room can host a call without a separate computer or conferencing kit. It suits boardrooms, lecture halls and training rooms.

How far can its microphones pick up speech?

The eight-microphone array has a pickup distance of 8 to 12 metres, with automatic gain control, echo cancellation and intelligent noise filtering. That makes it useful in a long boardroom or lecture hall where the presenter speaks from the front while remote participants sit at the far end of the table. Review the room layout during your site survey.

Can it be installed in an outdoor or unshaded area in Qatar?

No. The operating range is 0 °C to +40 °C with 10% to 90% non-condensing humidity, and Qatar summers regularly exceed 45 °C. Install it in an air-conditioned indoor room away from direct sunlight and window glare, and confirm the room conditions with the SmartRooms Qatar team before you request a quote.

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

Its power supply is rated 100 to 240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 318 W, rising to 453 W at maximum, and standby is 0.5 W or less. A power cord is included in the box. Ask your SmartRooms Qatar contact to confirm the plug type when you request a quote.

Can I connect a Windows laptop to it?

Yes, through the external module, which the source lists as compatible with Windows 7, 8, 10 and 11. The wireless plug-in module is included in the box. For a wired connection, use the HDMI input or the USB-C port, which carries 4K DisplayPort at 60 fps, touch and 5 W charging. Confirm the cable and module set-up for your laptop when quoting.

What software comes with it?

The source lists Deephub Meeting as free software and notes that collaboration features are not included. Before ordering for a meeting-heavy room, ask SmartRooms Qatar which features are available, and check that your preferred video conferencing app runs on Android 14.

How many people can write on the screen at once?

The touch layer is infrared and supports up to 32 touch points on Android and 50 on Windows. Up to 10 writing points can be used at the same time across more than 90% of the surface, and finger and pen input both work. Two styluses come in the box, and the pens attach magnetically to the unit, which suits group workshops.

Is it suitable for a classroom at a private school in Al Wakrah?

Yes, for large classrooms, science rooms and lecture spaces. The 4K resolution and 178-degree viewing angles keep diagrams and text readable from side seats, and the 86-inch size fills the front wall. A school equipping several rooms can issue a purchase order (LPO) and request one quotation covering all units.

Can it host video meetings with teams abroad?

The built-in camera offers face detection, auto white balance and up to 9x digital zoom, and the listed AI features include voice tracking and auto framing. Combined with the microphone array, this helps a ministry boardroom in West Bay include colleagues abroad without extra cameras. Confirm the conferencing platform you need with SmartRooms Qatar before ordering.

How much does it weigh and how should it be mounted?

Net weight is 65 kg and gross weight is 88.9 kg, so mounting needs two people and a wall that can take the load. The wall-mount holes are 800 mm by 400 mm apart, and the box includes a wall mount bracket and screw package. SmartRooms Qatar carries out a free site survey before installation.

What space does it need?

The unit measures 1,953.5 mm wide, 1,206 mm high and 87 mm deep. The frame borders are 40.9 mm at the top, 17.5 mm on each side and 65.3 mm at the bottom. Allow room for cable routing behind the panel, and consider the mobile bracket listed as an installation option if you prefer a stand to wall mounting.

What warranty applies to this model?

Products supplied by SmartRooms Qatar are covered by the manufacturer's warranty. The warranty duration and terms are not listed in the product data, so ask for the written terms in your quotation before placing a purchase order. Quotations are usually issued within one working day, and we accept LPOs, bank transfer, cheque and government tenders.
