Overview

The Dahua LDH55-WAI200L is a 55-inch LCD signage display with a 1080 × 1920 IPS panel, 3000 cd/m² typical brightness and Android 11.0 playback with 4 GB RAM and 32 GB storage. It is built for continuous operation, manages content by time and location, and can be controlled remotely from a central platform. It suits retail fronts, hotel lobbies and information points that need bright, always-on screens.

A 55-inch display built for long daily playback

The Dahua LDH55-WAI200L is a 55-inch LCD signage display for organisations that need screens running for many hours, such as menu boards, wayfinding, queue information and promotional loops. Its 1080 × 1920 IPS panel runs in portrait, the default orientation, or landscape, so one model can serve a tall column in a lobby or a wide wall in a corridor. The unit is designed to operate up to 24 hours a day.

Brightness and playback figures that matter

Typical brightness is rated at 3000 cd/m², with a 1200:1 typical contrast ratio and 178° viewing angles both horizontally and vertically. The DLED backlight and a 25% haze surface treatment help the picture stay readable in brighter areas, although any position facing a window still needs a glare check on site. Response time is 14 ms typical. Inside, a quad-core A55 processor at 1.92 GHz, 4 GB RAM and 32 GB ROM run Android 11.0. The player decodes H.265 HEVC and H.264 AVC up to 2160p and VP9 up to 2160p at 60 fps, so higher-resolution files can be loaded directly if they use these codecs.

Ports, audio and power

Inputs: one HDMI 2.1 input rated 1080p at 60 Hz, a 10/100/1000 Mbps Ethernet port, USB 2.0 and USB 3.0 Type-A ports, and a TF card slot up to 128 GB.
Audio: two built-in 5 W speakers and a 3.5 mm audio output jack.
Wireless: Wi-Fi is available through an optional external module. Bluetooth is not supported.
Power: 100–240 VAC at 50/60 Hz, maximum consumption of 360 W and standby consumption of 0.5 W or less.

Where it fits in Qatar

A retailer on a busy street in Msheireb or West Bay might want the unit in a shopfront to show offers, but its 0 °C to +40 °C operating range means it must sit in air-conditioned space. It is not rated for an open frontage exposed to summer heat above 45 °C. A hotel in Doha could use the portrait orientation in a lift lobby to display event schedules, with content managed from head office through the remote platform. A clinic in Al Sadd or a government service centre in Al Rayyan could deploy several units to share queue numbers and guidance, with content scheduled by time of day.

What to plan before ordering

The unit weighs 43 kg net and 48 kg gross, and measures 721 × 1,250 × 100 mm without its bracket. Ceiling mounting is the default. Wall mounting or a floor stand needs an extra bracket, and the rear has a 400 × 400 mm VESA pattern. Because of the weight, we recommend a site survey before installation to confirm that the ceiling or wall can carry the load and to plan cable routes. The box includes a ceiling mount bracket, power cord, remote control, screws and regulatory information.

To check whether this model suits your site, or to price a wall bracket or a multi-unit order, request a quote from SmartRooms Qatar. Quotations are usually issued within one working day, and we accept purchase orders (LPOs) from schools and government bodies.

Questions about LDH55-WAI200L

What is the Dahua LDH55-WAI200L used for?

It is a 55-inch LCD digital signage display for showing menus, information, wayfinding and promotional content over long daily operation. Its design for up to 24 hours a day suits reception areas, retail floors and corridors in Doha that run screens through working hours. Content is set up on the built-in Android player and can be managed centrally from the platform.

Can it sit in a window-facing position during Qatar summers?

Its 3000 cd/m² typical brightness and 25% haze surface treatment help reduce glare, but the operating range is 0 °C to +40 °C. Summer heat outside a Doha window can exceed 45 °C, so the unit should be placed in air-conditioned space. Confirm room conditions with the SmartRooms Qatar team before you request a quotation.

Can the display show both portrait and landscape content?

Yes. Portrait is the default display mode and landscape is also supported. Portrait suits a tall column or a directional sign at a clinic entrance in Al Sadd, while landscape suits a wide corridor wall in a school or a menu board in a café. One model can therefore cover both layouts without buying different units.

How does the intelligent split screen work?

The split screen lets you freely adjust the page layout, so a single display can show a video, a text panel and a clock in separate zones. This suits a hotel lobby in West Bay that shows event schedules beside a welcome video, or a bank branch that shows service information alongside promotions. Schedules for each zone are managed by time and location from the platform.

Which video and audio formats does it play?

Video formats include mp4, avi, mov, mkv and wmv. The player decodes H.265 HEVC and H.264 AVC up to 2160p, VP9 up to 2160p at 60 fps, and MPEG-4 and WMV/VC-1 up to 1080p. Audio formats listed are MPEG-3, WMA and WAV. Files outside these specifications should be converted before they are loaded.

Can one office manage several units across different sites?

Yes. The device supports unified platform management and remote control from the platform. It generates operation reports, releases programs through multi-level permission review, encrypts data transmission and is protected by a terminal password. A school or ministry with several sites in Doha can review and publish content from one central office.

Does it include built-in Wi-Fi or Bluetooth?

Wi-Fi is not built in. It is available only through an optional external module. Bluetooth is not supported. The main wired connection is a 10/100/1000 Mbps self-adaptive RJ-45 Ethernet port. If the installation site has no suitable wired network point, mention the need for the Wi-Fi module when you request a quotation.

Can I connect a second display through this unit?

No. The unit has no video output, so it cannot pass a signal on to another screen. It has one HDMI 2.1 input rated 1080p at 60 Hz, which can be used to connect a laptop or media player as an additional source. Each display needs its own source and its own player.

What mounting options are available?

Ceiling mounting is the default, and a ceiling mount bracket is included. Wall mounting or a floor stand requires an extra bracket. The rear VESA pattern is 400 × 400 mm. Because the unit weighs 43 kg net, a site survey is recommended before installing it in an office, school or lobby in Doha to confirm the structure can carry the load.

Is it suitable for Qatar's 240 V mains supply?

The power supply is rated 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Maximum consumption is 360 W and standby consumption is 0.5 W or less. A power cord is included. Confirm with the SmartRooms Qatar team that its plug suits the BS 1363 sockets in your building before you place the order.

How should I compare it with other 55-inch signage models?

Start with brightness, operating temperature range and orientation. This model's 3000 cd/m² typical brightness and 0 °C to +40 °C range suit indoor, air-conditioned sites that receive some daylight. Then check whether you need built-in Wi-Fi, since here it is an optional module. Send your site details with a quotation request and the SmartRooms Qatar team will confirm whether the model fits.

How can a school or government body order this display?

The display is supplied on a quotation. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including those through Monaqasat. Quotations are usually issued within one working day. Payment can be made by bank transfer, cheque or purchase order, and delivery covers all eight municipalities of Qatar.
