LDV55-PAI400TL

What this floor-standing kiosk is built to do

The LDV55-PAI400TL is a touch-enabled digital signage kiosk from Dahua's Pro Series, mounted on a floor base. It combines a 55-inch 4K panel in portrait orientation with an Android 11 player, so video, timetables, maps and interactive content run from the unit itself without a separate media computer. The black metal casing suits lobbies and corridors where the screen stands alone.

The manufacturer rates the unit for continuous operation, which makes it a practical choice for information points that must stay live through the day and night, such as a waiting-area display in a hospital or a timetable screen in a transport hub.

Display and touch performance in busy public spaces

• Resolution: 2160 × 3840 pixels, giving sharp text and fine graphics on a tall screen.
• Brightness: 700 cd/m² typical, with a 1% haze surface treatment to reduce reflections.
• Contrast: the manufacturer lists 1,200:1 typical for the IPS variant and 5,000:1 typical for the VA variant.
• Touch: capacitive, 10 touch points, response time of 8 ms or less.

Colour is shown as 10-bit (8-bit plus FRC), and viewing angles are 178 degrees horizontally and vertically, so people approaching from the side can still read the content. Two built-in 5 W speakers handle announcements and short clips, and a 3.5 mm output lets you connect an external sound system for larger halls.

Scheduling and remote management across several sites

Content can be scheduled by time and location, and the unit produces operation reports that show what played and when. Its browser-and-server architecture lets a central platform manage devices as one fleet and send remote control commands. Consider a school group with campuses in Al Khor and Lusail: one team in a central office can publish welcome messages and timetable notices to each kiosk, then check the reports to confirm each site ran its playlist.

Planning the install around Qatar's climate and floor space

Summer temperatures in Doha and the Industrial Area often exceed 45°C. This model is rated to operate between 0°C and 40°C and should be kept out of direct sunlight, so place it inside an air-conditioned space away from glass frontages and entrance sun. The rated humidity range is 10% to 85%, non-condensing.

Physical size matters on a busy floor. The product measures 1900 mm x 775 mm x 460 mm, weighs 57.6 kg net and 63.1 kg packed, so plan for at least two people to move it. A free site survey from SmartRooms Qatar lets us check floor space, cable routes and door widths before delivery. The power input is 100–240 VAC at 50/60 Hz with maximum consumption of 220 W, and our team will confirm that the supplied cord suits BS 1363 (Type G) sockets.

Connectivity, certifications and what to order with it

• One gigabit RJ-45 Ethernet port, with Wi-Fi available through an optional external module
• HDMI 2.1 input supporting 4K at 60 Hz, USB 2.0 and USB 3.0 ports, and a TF card slot up to 128 GB
• IR receiver, with base, remote control and power cord supplied
• No Bluetooth and no video output, so each unit runs as a standalone display

The manufacturer lists CE EMC, CE LVD and CE ERP certifications. SmartRooms Qatar supplies the kiosk with delivery across all eight municipalities of Qatar, professional installation and support for LPOs and government tenders.
