Overview

The Dahua LDV55-SAI400TL is a 55-inch indoor LCD signage kiosk built for portrait use, with a 2160 x 3840 panel, Android 11, 4K video decoding and 10-point capacitive touch. It plays scheduled content, can be managed remotely from a central platform and ships with a mounting bracket. It suits reception areas, service counters and school corridors across Doha, Lusail and Al Rayyan.

What this 55-inch portrait display is designed to do

The Dahua LDV55-SAI400TL is a floor-standing 55-inch LCD that runs upright on a 9:16 panel with 2160 x 3840 resolution. Its tall format suits content read from top to bottom, such as wayfinding directories, queue numbers, room timetables and vertical menus. Capacitive touch with 10 points lets visitors browse directly on the screen.

The panel uses an ELED backlight and IPS/VA technology, with 320 cd/m² typical brightness, 178 degree viewing angles on both axes and 10-bit colour (8-bit with FRC). An 8 ms response time keeps moving content clean, and a 1% haze surface treatment softens reflections. It is intended for indoor use, with an operating range of 0 to +40 °C and direct sunlight to be avoided.

Android player, decoding and split-screen layouts

Inside is a quad-core A55 CPU at 1.92 GHz, 4 GB of RAM and 32 GB of storage, running Android 11. The player 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. The intelligent split screen lets you arrange zones freely, so one display can show a video panel above a notice ticker.

Connectivity includes a self-adaptive RJ-45 Ethernet port (10/100/1,000 Mbps), an HDMI 2.1 input at 3840 x 2160 and 60 Hz, USB 2.0 and USB 3.0 Type A ports, a TF card slot up to 128 GB and a 3.5 mm audio output. Wi-Fi is not built in and needs an optional external module. Two 5 W speakers are built in.

Central management, scheduling and remote control

The display works within a browser-based (B/S) platform that schedules programs by time and location and produces operation reports, so you can confirm each screen ran as planned. Releases can pass through multi-level permission review, each terminal can be password protected, and platform data is transmitted encrypted. A facilities team can run screens across several floors or buildings from one place.

Where it fits in Qatar

Government service centres in Msheireb or Doha: a queue and service-information screen beside the ticket desk, with content scheduled by department.
Private schools in Al Wakrah or Al Rayyan: corridor screens showing timetables, events and notices, installed in air-conditioned corridors.
Hotel lobbies in West Bay or The Pearl: a vertical welcome or directory panel set back from glass frontages to keep it out of direct sunlight.

What to plan before ordering

Allow for a footprint of 1,850.0 mm x 743.6 mm x 92.3 mm without the bracket, and 1,900.0 mm x 750.0 mm x 460.0 mm with it. The unit weighs 66 kg net and 73 kg gross, so plan for two people to move it and a level, solid position. Power is rated 100 to 240 VAC at 50/60 Hz, drawing 80 W typical and 90 W maximum. Summer temperatures in Qatar can pass 45 °C outdoors, so the unit should sit in an air-conditioned room within its 0 to +40 °C range.

Book a free site survey before ordering several units so the team can check mounting points, cable routes and power outlets. Quotations are usually issued within one working day, and purchase orders (LPOs), government tenders and bank transfer, cheque or purchase order payment are supported. Request a quote for the Dahua LDV55-SAI400TL to confirm the bracket, quantity and installation plan for your site.

Questions about LDV55-SAI400TL

What is the Dahua LDV55-SAI400TL designed for?

It is a 55-inch indoor digital signage display that stands in portrait orientation, with capacitive touch and an Android 11 player. Its 9:16 panel suits wayfinding directories, queue information, timetables and vertical menus. Organisations use it where visitors need to read or touch content while passing, such as service counters and building entrances in Doha.

Can this display be installed outdoors or near windows in Qatar?

No. The unit has an operating range of 0 to +40 °C and should be kept out of direct sunlight, so outdoor siting is outside its rating. Place it in an air-conditioned area away from exterior glazing and open entrances. Ask the SmartRooms Qatar team to check the exact spot during the free site survey before you order.

What panel resolution, brightness and colour depth does it offer?

The panel is 2160 x 3840 pixels on a 9:16 aspect ratio, with 320 cd/m² typical brightness and 10-bit colour (8-bit with FRC, 1.07 billion colours). Viewing angle is 178 degrees horizontally and vertically, and response time is 8 ms. The 1% haze surface treatment softens reflections, so text stays readable when viewed from the side of a corridor.

Which video formats and resolutions can it decode?

The built-in player 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. It also handles H.264 MVC and MPEG-4 at 1080p, and WMV/VC-1 at 1080p. Supported containers are mp4, avi, mov, mkv and wmv, with MPEG-3, WMA and WAV audio.

How do I connect it to the network?

The display has one RJ-45 port with self-adaptive 10/100/1,000 Mbps Ethernet. Wi-Fi is not built in and requires an optional external Wi-Fi module, so ask for it in the quotation if wireless connection is needed. A TF card slot up to 128 GB and USB 2.0 and USB 3.0 Type A ports allow local media to be loaded directly.

How is content scheduled and managed across several screens?

Programs are managed through a browser-based (B/S) platform that schedules content by time and location and generates operation reports. Releases can pass through multi-level permission review, each terminal is protected by a password, and platform data is transmitted encrypted. The platform also remote-controls the display, which helps a facilities team running screens across a campus.

Does the touchscreen support multiple touches?

Yes. The capacitive touchscreen supports 10 touch points with a response time of 8 ms or less. This allows multi-finger gestures such as zoom on a shared kiosk, provided the content is designed to use them. Touch is useful in busy places such as government counters and information points where several visitors may browse at once.

Does it have built-in speakers?

Yes, two 5 W speakers are built in, and a 3.5 mm audio output jack is provided for connecting external audio equipment. The built-in speakers are suitable for short announcements in a small lobby or corridor. For a large atrium or hall, an external audio solution should be discussed during the site survey.

Will the power supply work with Qatar's electricity?

The power supply is rated 100 to 240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 80 W, rising to 90 W maximum, with standby below 0.5 W. A power cord is supplied in the box. Plan a power point near the mounting position and confirm the plug type with your quotation.

How heavy is it and what space does it need?

Without the bracket it measures 1,850.0 mm by 743.6 mm by 92.3 mm, and with the bracket 1,900.0 mm by 750.0 mm by 460.0 mm. It weighs 66 kg net and 73 kg gross, so plan for two people to lift it onto a sturdy, level position. Measure doors and lift routes in your building before delivery.

We are fitting out a school corridor in Al Wakrah. Is it a good fit?

Yes, provided the corridor is air-conditioned, because the unit is rated to 40 °C and should not sit in direct sunlight. The portrait format suits timetables, notices and event posters, and the split screen can separate a timetable from a promotional video. For several classrooms, one quotation can cover all units, and the school can issue an LPO.

Can a government ministry in Doha buy it through a tender?

Yes. SmartRooms Qatar supports purchase orders (LPOs) and government tenders, including Monaqasat, and quotations are usually provided within one working day. Payment can be made by bank transfer, cheque or purchase order. The unit is covered by the manufacturer's warranty, and the quotation should list the bracket, power cord and remote control to match the supplied accessories.
