What the LS550UCM-UF is built to do

The Dahua LS550UCM-UF is a 55-inch display unit with a 1920×1080 resolution, designed to be tiled with other units into one larger picture. The top and left bezels measure 2.3mm and the bottom and right bezels 1.2mm, so the gap between neighbouring screens is 3.5mm. That narrow join is the main reason to choose it over a standard commercial display, because the image reads as one surface rather than a grid of separate monitors.

Specifications that matter for a video wall

Brightness: 500 cd/m² with a 1,200:1 contrast ratio, suited to rooms with controlled lighting.
Panel: ADS LCD with an anti-glare surface (25% haze and 3H hardness), rated for continuous 24/7 operation.
Viewing angle: 178° horizontal and vertical, so the picture holds up for viewers standing or seated well off-centre.
Response time: 8ms grey-to-grey, with 8-bit colour depth.
Reliability: MTBF rated at 50,000 hours.

Connectivity covers VGA, DVI-D, two HDMI inputs and a DisplayPort input, plus a DisplayPort output for daisy-chaining units. The DisplayPort input and HDMI 1 accept up to 4K at 60Hz, while the DisplayPort output passes up to 4K at 30Hz to the next unit. RS232 and infrared control allow remote control from a computer, and the unit includes audio input and output.

Where it fits in Qatar

A command centre in Doha that monitors traffic, utilities or security feeds is a typical fit. Continuous running and the narrow bezel let operators read a large wall without a visible seam dividing the feeds. In West Bay or Msheireb, a corporate meeting room can use a single unit as a presentation screen or several units as a boardroom display wall. A school or training centre in Education City or Al Sadd could use a small grid in a briefing or lecture space.

Planning a wall installation

Each unit weighs 21.3kg net (31.1kg gross) and measures 1213.5mm × 684.3mm × 126.0mm. It can be floor-standing or wall-mounted on a 600×400mm VESA pattern with M6 fixings. A 3×3 grid would span roughly 3.6 metres wide and 2.1 metres high, and carry about 192kg of display weight before mounting hardware, so the wall structure, bracket rating and mounting height should be checked on site. SmartRooms Qatar offers free site surveys before installation.

The unit accepts AC 100V to 240V at 50/60Hz, which covers Qatar's 240V, 50Hz supply. Typical consumption is 140W and maximum consumption is 180W, with standby below 0.5W. The operating range is 0°C to 50°C at 20% to 80% humidity, non-condensing. Because Qatar summers can exceed 45°C, room cooling and airflow around the wall should be planned with that upper limit in mind. The EU energy efficiency class is G.

Questions about LS550UCM-UF

Who is the LS550UCM-UF designed for?

The LS550UCM-UF is a 55-inch Full HD display unit for organisations that need a multi-screen wall running for long hours. Its ADS panel is rated for continuous 24/7 operation and has an MTBF of 50,000 hours. Typical users are command and control rooms, surveillance centres and commercial display areas. For a single small meeting room a standard display may suffice, so the bezel and tiling features matter most when several units are combined.

How narrow is the bezel, and does it matter on a wall?

The bezel is 2.3mm on the top and left and 1.2mm on the bottom and right, giving a 3.5mm gap between neighbouring units. On a wall of several panels, a narrow gap keeps the image reading as one surface, which matters for dashboards, maps and camera feeds that span screens. Wider frames break lines and text at each joint, so this figure is the main reason to specify the model for tiled displays.

Can units be daisy-chained, and what resolution passes through?

Yes. The DisplayPort output passes the signal from one unit to the next, which reduces the number of cable runs from the source. The DisplayPort input and HDMI 1 accept up to 4K at 60Hz, but the DisplayPort output carries up to 4K at 30Hz. Plan your source, cabling and layout with this limit in mind, and confirm the final configuration with the SmartRooms Qatar team when you request a quote.

What inputs and control options does the unit have?

The unit provides VGA, DVI-D, two HDMI inputs, one DisplayPort input, RS232, infrared and audio input, with DisplayPort, RS232 and audio outputs. Control is possible through infrared or RS232 in dual mode, and the specification states remote control by computer is supported. This means a central computer can be used to manage the wall, so operators do not need to touch each panel.

Is it suitable for a 24/7 command centre in Doha?

Yes. The panel is described as suitable for continuous 24/7 operation, with an MTBF of 50,000 hours. Command centres in Doha often show continuous feeds, from traffic and utilities to security cameras. Pair the wall with a cooling plan for the room, because the operating range tops out at 50°C. Ask SmartRooms Qatar to confirm the layout when you request a quote.

Can it cope with Qatar's summer heat?

The operating range is 0°C to 50°C at 20% to 80% humidity, non-condensing. Qatar summers can exceed 45°C, which leaves a narrow margin. The wall should therefore sit in an air-conditioned room with airflow around the cabinets, and not in a sun-exposed area or a space with poor ventilation. Confirm the actual installation environment with the SmartRooms Qatar team before ordering.

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

Yes. The power input is rated AC 100V to 240V at 50/60Hz, which includes Qatar's 240V, 50Hz supply. Typical consumption is 140W and maximum consumption is 180W, with standby below 0.5W. Power is built into the unit, so each screen does not need a separate external power adapter, but the electrical circuit for each unit should be sized for the 180W maximum when planning the wall.

How heavy is a video wall of these units, and how is it mounted?

Each unit weighs 21.3kg net and 31.1kg gross, measures 1213.5mm by 684.3mm by 126.0mm, and mounts on a 600×400mm VESA pattern with M6 fixings. A 3×3 wall would carry roughly 192kg of display weight before brackets are counted. Units can be floor-standing or wall-mounted, so the wall structure, bracket rating and height should be checked during a site survey, which SmartRooms Qatar offers free of charge.

Can it be controlled from a computer or a central control system?

Yes. The unit supports infrared and RS232 control in dual mode, and the specification lists remote control by computer. An RS232 connection suits a dedicated control system or a PC running control software, while infrared control is useful where a local handset is needed in a meeting room. Confirm the control setup and cabling requirements with the SmartRooms Qatar team when you request a quote.

Is it a good fit for a meeting room or boardroom in West Bay?

A single 55-inch unit suits smaller meeting rooms and breakout spaces, where it works as a presentation screen at 1920×1080. For a large boardroom, check the viewing distance from the furthest seats before choosing, because content can look small from the back rows. SmartRooms Qatar can advise on the right screen size for your room after reviewing the layout.

How do I request a quote and what happens next?

Send your room or control-room layout, the number of units, whether they will be floor-standing or wall-mounted, and details of the source equipment you plan to connect. SmartRooms Qatar usually returns a quotation within one working day. We supply and deliver to all eight municipalities of Qatar, offer professional installation, accept purchase orders and government tenders, and accept payment by bank transfer, cheque or purchase order.
