Request a quote for supply and installation.

What the LDH65-HAI400L does on the wall

The Dahua LDH65-HAI400L is a 65-inch LCD display built for digital signage. It plays scheduled content from its own storage, runs Android 11, and can be managed from a central platform. The 3840 × 2160 panel shows 4K material at full resolution, and the unit is rated for 24/7 operation, which suits corridors and lobbies that never switch off.

The screen mounts on a 400 × 400 mm VESA pattern and can run in landscape or portrait. The same unit can serve as a wayfinding board beside a lift or a menu strip next to a reception desk.

Where it fits in Qatar

A private school in Al Wakrah could place one unit in a corridor to show timetables, events and announcements, with the schedule set centrally by the school office. A bank branch in West Bay could use one in its waiting area to run service messages and product information throughout the working day. A clinic in Msheireb could show queue numbers and health guidance in a reception area that stays within the unit's indoor operating range.

What to plan before installation

The unit weighs 26.5 kg net and 35.4 kg gross, and measures 1,451.8 × 826.7 × 25.0 mm without the bracket and 27.5 mm deep with it. Its frame is 10.3 mm on each side. Two people should handle the panel, and the wall must be sound enough to carry the load on a 400 × 400 mm mount.

The operating temperature range is 0 °C to +40 °C, and the product is marked to avoid direct sunlight. Qatar summers regularly exceed 45 °C outdoors, so keep the screen away from sunlit windows, outdoor walls and any position where heat builds up around it. SmartRooms Qatar offers a free site survey to check the wall, the sightlines and the room conditions before the unit is mounted.

For schools or offices ordering several units, a purchase order (LPO) works for the quotation. Request a quote and SmartRooms Qatar will confirm the bracket, accessories and installation scope for your site.

Questions about LDH65-HAI400L

What is the Dahua LDH65-HAI400L used for?

It is a 65-inch indoor wall-mounted LCD display for digital signage. It plays scheduled video and image content from 32 GB of internal storage, supports landscape or portrait display, and can be managed remotely. It suits corridors, reception areas, waiting rooms and lobbies in schools, clinics, banks and offices across Qatar.

Will it run on Qatar's 240 V mains supply?

Yes. The power supply is rated 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 141 W and the maximum is 172 W, with standby at 0.5 W or less. The source data does not list the plug type, so the SmartRooms Qatar team will confirm the socket arrangement when you request a quote.

Can it be installed near windows or outdoors in Qatar summer heat?

No, not in sunlit or outdoor positions. The operating range is 0 °C to +40 °C and the product is marked to avoid direct sunlight. Qatar summer temperatures often exceed 45 °C, so mount it indoors, away from window glare and heat sources, and confirm the room conditions with the SmartRooms Qatar team.

How is content scheduled and managed?

The unit manages playlists by time and location and generates operation reports. It can be controlled remotely through the manufacturer's unified management platform. Before ordering, ask the SmartRooms Qatar team how the platform will be set up for your sites, especially if you plan to manage several screens from one office.

Which video and audio formats does it play?

Video formats include mp4, avi, mov, mkv and wmv. Decoding covers H.265 and VP9 up to 2160p at 60 fps, and H.264 up to 2160p at 30 fps. Audio files include WMA and WAV. Local content can also be loaded from a TF card of up to 128 GB.

Can I show content in portrait orientation?

Yes. The display mode supports both landscape and portrait, and the built-in split-screen function lets you adjust page layouts freely. This is useful for a vertical directory beside a lift or a narrow corridor screen in a Doha office tower, where a portrait panel uses the wall space better than a landscape one.

How much does the unit weigh and what wall support does it need?

The net weight is 26.5 kg and the gross weight is 35.4 kg. It uses a 400 × 400 mm VESA pattern and is supplied with a wall-mount bracket. The panel is 25.0 mm deep without the bracket and 27.5 mm with it. SmartRooms Qatar offers a free site survey to confirm the wall before mounting.

Does it have built-in speakers?

It has two 5 W built-in speakers. There is also a 3.5 mm audio output, which can feed an external amplifier or speaker system when a louder or wider sound is needed, such as in a large reception hall or a school assembly area.

Which connections are available for source devices and networks?

It has one HDMI 2.1 input supporting 4K at 60 Hz, one gigabit Ethernet port, 802.11 b/g/n/a/ac/ax Wi-Fi, one USB 2.0 port, one USB 3.0 port and a TF card slot. Wired network connection is the more stable choice for scheduled playback in a school or bank branch.

Which certifications does it carry?

The source lists CE EMC, CE LVD, CE ERP and RED certifications. The source does not list any Qatar-specific approval, so if your project requires a particular local approval, ask the SmartRooms Qatar team to confirm before you submit a tender or a purchase order.

Is the product covered by warranty and how do I order several units?

Products supplied by SmartRooms Qatar are covered by the manufacturer's warranty. The source data does not list the warranty period, so the quotation will state the applicable terms. Schools, hospitals and government bodies can order several units under a purchase order (LPO) or through a tender, with quotations usually issued within one working day.

Is it a good choice for a corridor screen in a school in Education City?

It can be, for a corridor or common area where timetables, events and announcements change during the day. Its scheduling, remote management and 4K playback suit that use. Confirm the wall, power point and network point during a free site survey before you order the number of units your building needs.
