Overview

The Dahua LPH86-ST470-C-S3 is an 86-inch 4K interactive whiteboard from the ST470-C education series. It combines a 3840 × 2160 panel with 50-point infrared touch, an Android 16.0 system with 8 GB RAM and 128 GB storage, an eight-array microphone and two 20 W speakers. It suits large classrooms, lecture halls and training rooms across Qatar. Request a quote to plan your installation.

Panel and touch performance for large rooms

The LPH86-ST470-C-S3 uses an 86-inch 16:9 DLED panel with 3840 × 2160 resolution, giving 4K detail for small text, spreadsheets and engineering drawings shown to a full room. The panel is rated at 400 cd/m² brightness and 1500:1 static contrast, with viewing angles of 178 degrees both horizontally and vertically, so learners or delegates seated at the sides still see a clear picture. The refresh rate is 60 Hz and response time is 8 ms or less.

Touch is infrared and uses a zero air gap attachment, which places the touch layer close to the glass. The 3 mm anti-dazzle tempered glass has a surface hardness of at least 9H, and touch accuracy is ±0.5 mm across 90% of the area. Writing works with fingertips and a magnetic stylus, and two stylus pens are supplied. The manufacturer rates touch at 50 points on both Android and Windows.

An integrated Android system with flexible inputs

The built-in system runs Android 16.0 on a quad-core A53 and quad-core A72 processor at 2.2 GHz, with a Mali-G52 MC3 GPU, 8 GB RAM and 128 GB storage. The external module supports Windows 11 or Android, so teams can choose the environment that matches their software. Wireless options include Wi-Fi 6 on 2.4 GHz and 5 GHz, Bluetooth 5.4, NFC and 13.56 MHz RFID, and a wireless plug-in module is included in the box.

Wired inputs include HDMI on the front and two HDMI inputs on the rear, a DisplayPort input, a VGA input with audio and a Type-C input. Outputs include HDMI, SPDIF and line out. USB 3.0 ports appear on both the front and the rear, and there are two RJ-45 ports and an RS-232 port for control. An SD card slot accepts cards up to 512 GB. Ports on both sides of the panel let presenters connect a device without reaching behind the board.

Speakers and microphones for lessons and meetings

Two speakers, each rated at 20 W, deliver 2.0-channel sound across 150 Hz to 20 kHz. The eight-array microphone picks up speech from 0.5 m to 8 m and includes automatic gain control, echo cancellation and intelligent noise filtering. In a lecture hall of moderate depth, a presenter standing at the board can often be heard without a separate microphone, which can reduce the wiring needed for a lectern system. Confirm the room layout during the site survey, because reflective walls and air conditioning noise affect results.

Where it fits in Qatar and what to plan for

The overall dimensions are 1,953.8 mm × 115.7 mm × 1,205.9 mm. The net weight is 61.7 kg and the gross weight is 74.0 kg. The mounting holes are spaced 800 mm × 400 mm, and a wall mount bracket with an expansion tube and screw set is included. A private school in Al Wakrah fitting out a larger classroom, a training centre in Education City running workshops, or a government meeting room in West Bay each needs a wall that can carry that weight, so a free site survey before drilling is worth scheduling.

Classrooms and lecture halls: the 86-inch screen and 8 m pickup range suit large groups.
Boardrooms and training rooms: a laptop can connect through the built-in ports for calls with teams abroad.
Mobile use: the manufacturer lists a mobile bracket option for rooms where a wall fixing is not possible.

Environment matters. The operating range is 0 °C to +40 °C with humidity from 0% to 93%, and the IP20 rating means the board is designed for dry indoor rooms. Outdoor temperatures in Qatar often pass 45 °C in summer, so keep the board in an air-conditioned room and away from direct sun through glass. The power supply accepts 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 135 W, rising to 400 W at maximum, with standby at 0.5 W or less. Have an electrician check the socket and circuit before installation.

Questions about LPH86-ST470-C-S3

Who is the LPH86-ST470-C-S3 designed for?

It is an 86-inch interactive whiteboard from the ST470-C education series, built for classrooms, lecture halls and training rooms that need a large shared screen and touch writing. Schools, universities and corporate training teams in Doha, Lusail and Al Rayyan are typical buyers. Its 3840 × 2160 panel and 8 m microphone pickup suit groups of learners or delegates in one large room.

What size room does an 86-inch board suit?

An 86-inch screen suits large classrooms, lecture halls, boardrooms and training rooms rather than small offices. Overall dimensions are 1,953.8 mm × 115.7 mm × 1,205.9 mm, and the net weight is 61.7 kg. Before choosing a position, check that the viewing distance works for the back row and that the wall can carry the weight. A free site survey covers both points.

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

It uses infrared touch with a zero air gap attachment and 3 mm anti-dazzle tempered glass rated at least 9H. The manufacturer rates touch at 50 points on both Android and Windows, with response of 1.67 ms or less and accuracy of ±0.5 mm across 90% of the area. Finger and magnetic stylus input both work, and two stylus pens are included.

Which operating systems are available?

The built-in system runs Android 16.0 on a quad-core A53 and quad-core A72 processor at 2.2 GHz, with 8 GB RAM and 128 GB storage. The external module supports Windows 11 or Android. Ask your IT team which environment your teachers need before ordering, especially if some applications run only on Windows.

What wireless connectivity is included?

The board supports Wi-Fi 6 with 802.11a/b/g/n/ac/ax on 2.4 GHz and 5 GHz, Bluetooth 5.4, NFC and 13.56 MHz RFID. A wireless plug-in module is in the box. These options let presenters connect devices without cables, and IT teams should review the network policy before deployment, particularly where guest Wi-Fi is restricted.

How do the speakers and microphones perform in a lecture hall?

Two built-in speakers each provide 20 W across 150 Hz to 20 kHz. The eight-array microphone picks up speech from 0.5 m to 8 m and includes automatic gain control, echo cancellation and intelligent noise filtering. In a lecture hall of moderate depth, a presenter at the board can often be heard without a separate microphone. Test the acoustics during the site survey.

Which ports do I need for laptops, cameras and PCs?

Front ports include HDMI input, a Type-C port, two USB 3.0 ports and a touch port. Rear ports add HDMI output, two HDMI inputs, a DisplayPort input, a Type-C input, two RJ-45 ports, USB 2.0, RS-232 and VGA with audio input. At an international school in Lusail where teachers bring laptops to class, the front ports cover daily use while the rear ports serve fixed equipment.

What power does it need, and does it run on Qatar mains?

The power supply is rated 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz supply. Consumption is 135 W basic and 400 W maximum, with standby at 0.5 W or less. A power cord is included. Ask your electrician to confirm that the supplied cord matches the socket type in your room before the board is installed.

Can it be wall mounted in a government meeting room?

Yes. The source data lists wall mount or mobile bracket installation, with mounting holes spaced 800 mm × 400 mm. A wall mount bracket and an expansion tube and screw set are included. With a net weight of 61.7 kg, the wall must be checked before drilling. SmartRooms Qatar offers a free site survey and professional installation to confirm the fixings first.

Is it suitable for Qatar's summer heat and dust?

The operating range is 0 °C to +40 °C with humidity from 0% to 93%, and the IP20 rating means it is designed for dry indoor use. Outdoor temperatures in Qatar often exceed 45 °C in summer, so keep the board in an air-conditioned room, away from direct sunlight through windows. Installing it in a closed, clean room also limits dust build-up.

What is in the box, and how should a school order several units?

The box includes the display, two stylus pens, a remote control, a wall mount bracket, a wireless plug-in module, a power cord, a quick start guide, an expansion set and a regulations manual. Schools and government bodies can order several boards under one LPO or tender. SmartRooms Qatar accepts purchase orders and government tenders, including Monaqasat, and quotations are usually issued within one working day.
