What the LDH22-SAI200L does for a wall-mounted screen

The Dahua LDH22-SAI200L is a 21.5-inch wall-mounted LCD display built for information and advertising content. Its Android 11 media player sits inside the unit, so the screen plays its own schedules without a separate media box behind it. The Standard Series model is rated for continuous daily operation and can be turned from landscape to portrait, which suits wayfinding in tall corridors as well as menu and promotional content.

Panel and processing: the figures that matter

The IPS panel has a 1920 × 1080 resolution and a 16:9 aspect ratio, with typical brightness of 250 cd/m² and a typical contrast ratio of 1000:1. Viewing angles are 178° horizontally and vertically, so content stays readable for people standing to the side of the screen. The 25% haze surface treatment softens reflections from overhead lights and windows, which helps in lobbies with large glazing.

Quad-core A55 processor at 1.92 GHz with 4 GB RAM
32 GB internal storage and a TF card slot up to 128 GB
Decodes H.265 and H.264 video up to 2160p
Built-in 2 × 2 W speakers and a 3.5 mm audio output

Connectivity and remote management

Wired networking uses a 10/100/1000 Mbps RJ-45 Ethernet port, and Wi-Fi is available through an optional external module. The single HDMI 2.1 input accepts a 1080p signal at 60 Hz from a laptop or media player, but the unit has no video output, so it cannot pass the signal on to a second screen. Two USB ports (USB 2.0 and USB 3.0, both type A) and an IR receiver for the included remote complete the port list. Bluetooth is not fitted.

Scheduling is handled by a browser/server (B/S) platform. Programmes can be assigned by time and location, the platform generates operation reports, and each terminal can be controlled remotely from the platform. Data transmission is encrypted, programme releases pass through multi-level permission review, and every terminal can be protected with a password. For a multi-site buyer in Qatar, one team can manage screens in Doha and Al Khor from a single place.

Where it fits in Qatar

Three typical settings suit this model. In a clinic waiting room in Al Sadd, a 21.5-inch screen can show queue information, opening hours and health awareness messages prepared by the facility team. In a bank branch in West Bay, a unit beside the teller queue can rotate product offers on a schedule. In a shopping mall in Lusail, a portrait-mounted version beside a lift lobby can display a store directory. Keep the screen in an air-conditioned indoor space: the operating range is 0 °C to +40 °C and direct sunlight should be avoided, which matters when summer temperatures in Qatar can exceed 45 °C.

What to plan before ordering

Start with the wall. The unit weighs 5.1 kg net without its bracket, measures 519.14 mm × 310.6 mm × 48.1 mm, and uses a 100 mm × 100 mm VESA pattern, with a wall-mount bracket supplied. Power input is 100–240 VAC at 50/60 Hz, with 20 W typical and 25 W maximum consumption, so plan the position of the power point as well as the cable route. A free site survey from SmartRooms Qatar confirms the mounting point, power and network access before installation.

Questions about LDH22-SAI200L

What is the Dahua LDH22-SAI200L used for?

It is a 21.5-inch wall-mounted LCD screen for showing information, schedules and promotional content without a separate media box. Typical sites in Qatar include clinic waiting areas in Al Sadd, bank lobbies in West Bay and mall corridors in Lusail. Because the Android 11 player is built in, the screen runs its own playlists once content has been loaded and scheduled. It suits buyers who need a single, wall-fixed display rather than a video wall.

Can it be mounted in portrait orientation?

Yes. The display mode supports both landscape and portrait, so the 21.5-inch panel can be mounted vertically for directory boards or wayfinding in a tall lift lobby or corridor. A wall-mount bracket is included, and the VESA pattern is 100 mm × 100 mm. During the site survey, confirm that the wall can carry 5.1 kg and that the bracket lines up with the power point and network outlet.

Is it rated to run 24 hours a day?

The manufacturer states that the unit works up to 24 hours a day. Typical power draw is 20 W, rising to 25 W at maximum, which helps when you plan for several screens in a hospital reception or hotel lobby in Doha. Keep the unit in a ventilated indoor space, because its operating temperature is limited to 0 °C to +40 °C.

Can I install it outdoors or near a window in summer?

No, not in an unshaded outdoor or hot location. The operating range is 0 °C to +40 °C and direct sunlight should be avoided, while summer temperatures in Qatar can exceed 45 °C and dust storms are common. Choose an air-conditioned indoor wall away from sun falling through glass, and ask the SmartRooms Qatar team to review the exact position during the free site survey.

Which video formats and resolutions can it play?

The processor decodes H.265 HEVC up to 2160p at 60 fps, H.264 AVC up to 2160p at 30 fps, and VP9 Profile 2 up to 2160p at 60 fps, plus older codecs up to 1080p. Supported file formats are mp4, avi, mov, mkv and wmv. The panel itself is 1920 × 1080, so 4K files are shown at the screen's native resolution.

Can I connect a laptop or media player through HDMI?

Yes. The unit has one HDMI 2.1 video input that accepts a 1080p signal at 60 Hz, which suits a presenter laptop or external media player in a meeting room or event venue. It has no video output, so it cannot pass the signal on to another display. When no source is connected, content stored on a USB device or TF card can be played instead.

Does it support Wi-Fi and Bluetooth?

Wi-Fi is available only through an optional external module, while wired networking is built in through a 10/100/1000 Mbps RJ-45 port. Bluetooth is not supported. For fixed screens in a school, office or clinic in Qatar, a wired connection is usually preferred, and the optional Wi-Fi module can be added where cabling is impractical. Confirm the module requirement when you request your quote.

How are several screens managed from one place?

The unit works with a browser/server (B/S) platform for central management. Operators can schedule programmes by time and location, generate operation reports, and remotely control each terminal. Data transmission is encrypted, programme releases pass through multi-level permission review, and each terminal can be password protected. For a retail group with outlets in Lusail, Al Wakrah and Doha, one team can update every screen without visiting each branch.

Does it have built-in speakers?

Yes, it has two 2 W speakers, which suit short announcements or background tones in a small lobby or waiting area. For a larger hall, use the 3.5 mm audio output to connect an external amplifier and speakers. The built-in speakers are not a substitute for a public address system in a stadium or conference hall, so plan audio separately in noisy environments.

Will it work with Qatar mains power and the supplied cord?

The power input is 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz supply. The unit ships with a power cord, but the plug type is not specified in the source data, so confirm that the supplied cord matches BS 1363 (Type G) sockets at your site before ordering. Standby consumption is 0.5 W or less.

What wall space and weight do I need to plan for?

The unit measures 519.14 mm × 310.6 mm × 48.1 mm without its bracket and weighs 5.1 kg net, with a gross shipping weight of 6.2 kg. It uses a 100 mm × 100 mm VESA pattern and includes a wall-mount bracket. Plan for a solid wall or suitable fixings, and book a free site survey so SmartRooms Qatar can check mounting height, cable routing and the power point.

Can a school or government office buy several units on a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs), payment by bank transfer, cheque or purchase order, and supports government tenders including Monaqasat. A school in Al Rayyan equipping several corridors can request one quotation covering all units, with the bracket, power cord and remote control listed for each screen. Include the number of units and their locations in your request to get an accurate quote.
