What the LS490UCM-EF is designed to do

The Dahua LS490UCM-EF is a 49-inch video wall display unit with a 1920×1080 Full HD resolution. It is built to be tiled with other units so that several screens act as one large image, and its 3.5mm bezel-to-bezel gap keeps the joins between screens unobtrusive. It uses an ADS panel suited to continuous 24-hour, seven-day operation, which matters for rooms that cannot pause, such as monitoring centres and command rooms.

Specifications that matter when you tile screens

On a video wall, the frame is the first detail people notice after the picture. The LS490UCM-EF has a 2.3mm edge on the top and left and a 1.2mm edge on the bottom and right, so two units placed side by side leave a 3.5mm seam. Brightness is rated at 500 cd/m² and contrast at 1,200:1. The anti-glare surface carries 25% haze and a 3H surface treatment, which helps in rooms with overhead lighting or daylight from windows. Response time is 8ms grey-to-grey, colour depth is 8-bit (16.7 million colours), and factory calibration is aimed at uniform colour across tiles.

Connecting and controlling a wall

The unit provides one HDMI input, one DVI-D, one VGA, one composite video input on BNC, two USB ports, audio and infrared. It also offers two HDMI outputs, so a source can pass from one unit to the next in an HDMI daisy chain. For control, it supports infrared and RS232 in dual mode, and RS232 allows remote control from a computer. For a wall of several units, the HDMI chain and RS232 control make it practical to run the whole array from one source and one control point.

Where it fits in Qatar and how to plan the installation

A security operations room in Msheireb or the Industrial Area can tile camera feeds across a wall that runs through night shifts. A boardroom in West Bay or Lusail can show one wide picture from a single source, alongside a separate video conferencing system for calls with colleagues abroad. A hospital or clinic lobby in Doha can use a tiled wall for wayfinding and public information, provided the space is air-conditioned.

Each unit measures 1078.4mm by 608.4mm by 120.8mm and weighs 19.5kg net (28.1kg gross). A six-unit wall, arranged three across and two high, will therefore span roughly 3.24m by 1.22m before any frame or trim. The unit can be floor-standing or wall-mounted, using a 600×400mm VESA pattern with M6 holes. Typical power draw is 135W and maximum is 155W, with standby below 0.5W. The input range of AC100V to AC240V at 50/60Hz covers Qatar's 240V, 50Hz mains. Operating temperature is 0 to 40°C with 10% to 80% humidity, non-condensing.

Qatar summer temperatures often exceed 45°C, which is above the unit's stated operating range, so install the wall in an air-conditioned room and confirm the cooling with the SmartRooms Qatar team before fixing it. Delivery covers all eight municipalities, and quotations are usually issued within one working day. Request a quote for your LS490UCM-EF wall, including the number of units, bracket type and cable needs, and we will confirm lead times with the quotation.

Questions about LS490UCM-EF

What is the Dahua LS490UCM-EF designed for?

It is a 49-inch Full HD display unit built to be tiled into a larger video wall. With a 1920×1080 ADS panel and a 3.5mm bezel-to-bezel edge, it suits control rooms, surveillance centres and meeting rooms where several screens must show one continuous picture. Quotations for single units or complete walls are available on request.

Is it suitable for a security control room in Doha that runs around the clock?

Yes. The panel is described for continuous 24-hour, seven-day operation, which fits a security operations room in Msheireb or the Industrial Area that runs night shifts. The unit's infrared and RS232 control lets operators switch the wall from a desk. Ask for a quotation that includes mounting and cabling for your room layout.

How narrow is the bezel, and what seam does a wall show?

The bezel is 2.3mm on the top and left and 1.2mm on the bottom and right, so two units placed side by side leave a 3.5mm seam. That narrow gap keeps camera feeds and dashboards looking like one picture rather than separate monitors. The seam matters most when viewers sit close to the wall, so check viewing distances during planning.

How big is a six-unit wall of these displays?

Each unit measures 1078.4mm by 608.4mm, so a wall of six, three across and two high, is roughly 3.24m wide and 1.22m high before any frame or trim. That size suits a boardroom in West Bay or Lusail where the wall sits behind a long table. Confirm the room dimensions during a free site survey before ordering.

Can I daisy-chain the picture from one unit to the next?

Yes. The unit has two HDMI outputs and supports HDMI daisy-chaining, so one source can feed several units in sequence. This reduces the number of cable runs across a wall, which helps in a school hall or hotel lobby where cable routes are limited. Confirm the chain layout with the SmartRooms Qatar team before installation.

Which inputs does it have for laptops and older equipment?

The inputs are HDMI, DVI-D, VGA, composite video on BNC, two USB ports, audio and infrared. A modern laptop connects through HDMI, while an older PC or analogue encoder can use VGA, DVI-D or the BNC input. Check your source outputs before ordering so the right cables and adapters are included in the quotation.

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

Yes. It supports infrared and RS232 in dual control mode, and the manufacturer describes remote control by computer. The unit also has an RS232 output, so control can be carried along the chain. Tell us your control system when requesting a quote so we can confirm the connection method and cabling you will need.

Can it run in a non-air-conditioned space during Qatar's summer?

No. The stated operating temperature is 0 to 40°C with humidity from 10% to 80%, non-condensing, while Qatar summer temperatures often exceed 45°C. Install the wall in an air-conditioned room such as a control room or boardroom, and confirm the room's cooling capacity before installation. Avoid open-air or sun-exposed positions.

How much power does it draw, and does it work on Qatar mains?

Typical consumption is 135W and maximum is 155W, with standby below 0.5W. Built-in power accepts AC100V to AC240V at 50/60Hz, which covers Qatar's 240V, 50Hz supply. The EU energy efficiency class is G. For a six-unit wall, plan the combined load on the distribution board, and ask our team to check the circuit before installation.

What mounting options does it support, and what should I plan for?

It can be floor-standing or wall-mounted, with a 600×400mm VESA pattern using M6 holes. The net weight is 19.5kg and the gross shipping weight is 28.1kg, so plan for lifting equipment on a multi-unit wall. A free site survey helps confirm wall load, bracket type, cable routes and ventilation before the wall is fixed.

Can a hospital or clinic lobby in Doha use this display?

It can work in an air-conditioned hospital or clinic lobby, where a tiled wall can show wayfinding, appointment information or public notices. Keep the room within the stated 0 to 40°C operating range and keep the screens out of direct sunlight through glass. With infrared and RS232 control, staff can power and switch the wall from a desk or a central controller.

We need several units for a government or school tender. How do you supply them?

SmartRooms Qatar supplies by quotation and accepts purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. Delivery covers all eight municipalities of Qatar, and quotations are usually issued within one working day. Products are covered by the manufacturer's warranty. Send the quantity and tender reference to receive a quote for your units.
