Overview

The Hikvision DS-6901UDI(C) is a 4K video wall decoder with one HDMI 1.4 output at 3840 × 2160 and 30 Hz. It decodes 16 channels at 2 MP to a wall, supports 64 scenes and 100 view groups, and adds 8 alarm inputs and 8 alarm outputs. It suits control rooms and operations centres in Doha that monitor several camera feeds on one display wall.

What the DS-6901UDI(C) does on a video wall

The DS-6901UDI(C) sits between your IP cameras, recorders and computers on one side and the display wall on the other. It receives streams from network cameras, NVRs, DVRs and computers, decodes them, and sends the result through a single HDMI 1.4 output at up to 4K, which is 3840 × 2160 at 30 Hz. Where a larger wall is needed, several decoders can be combined, each feeding its own part of the layout.

Decoding capacity and window layouts

The unit provides 16 decoding channels and can decode 16 channels of 2 MP video to the wall at the same time. It handles streams up to 32 MP and supports H.264, H.265, Smart264, Smart265 and MJPEG formats. Each screen can carry four 1080p windows or two 4K windows, and every signal window can be divided into 1, 2, 4, 6, 8, 9, 12 or 16 sub-windows. Operators can save up to 64 scenes and set up to 100 view groups on the HCP client, each with its own cameras, scene and timing.

Where it fits in Qatar

Industrial operations room: a plant in Mesaieed or Ras Laffan can show gate, pipeline and yard cameras on one wall, with eight alarm inputs available for site signals.
Security control room in Doha: a monitoring room in West Bay or a government facility can keep saved layouts ready for different shifts and camera groups.
Campus operations centre: a university in Education City can bring lecture-hall computers and campus camera feeds onto a central display through its HDMI inputs.

What to plan before ordering

Fix the number of sources and the wall layout first, since the unit handles 16 decoding channels.
Check that the wall input accepts 3840 × 2160 at 30 Hz or the lower resolution you choose.
Plan network capacity around the single 10/100/1000 Mbps RJ-45 port and your camera streams.
Prepare a power point for the external 12 VDC adapter; the unit draws less than 15 W.
Review ventilation and mounting location, as the rated working range is -10 °C to 55 °C.

Control, access and maintenance

Administrators can reach the device through a PC client or a Chrome 45 or later browser, and it supports IPv4 and IPv6 at the same time. It offers PTZ control of network sources, keyboard control, and ONVIF access for integration. Failure alarms cover network disconnection, IP conflicts, illegal access, temperature threshold exceeding and decoding exceptions. Remote restart, parameter import and export, and device upgrades are also supported.

Questions about DS-6901UDI(C)

What is the Hikvision DS-6901UDI(C) used for?

It is a 4K video wall decoder. It takes streams from network cameras, NVRs, DVRs and computers, decodes them and shows them on a video wall through one HDMI 1.4 output. It suits security and operations teams that need several camera feeds, or a mix of camera feeds and presentation sources, on one large display. Request a quote and the SmartRooms Qatar team will confirm the layout for your room.

What output resolution does the decoder support?

The single HDMI 1.4 output runs at up to 4K, which is 3840 × 2160 at 30 Hz. The source data also lists 2560 × 1440 at 30 Hz, 1920 × 1080 at 60 Hz and 50 Hz, 1920 × 1200 at 60 Hz, 1280 × 1024 at 60 Hz, 1024 × 768 at 60 Hz and several lower resolutions. Confirm during the site survey that your wall controller accepts the mode you choose before ordering.

How many camera feeds can one decoder show on a wall?

It has 16 decoding channels and can decode 16 channels of 2 MP video to the wall simultaneously. Each screen holds four 1080p windows or two 4K windows, and each window can be divided into 1, 2, 4, 6, 8, 9, 12 or 16 sub-windows. It decodes streams up to 32 MP and supports H.264, H.265, Smart264, Smart265 and MJPEG formats. If a wall needs more than 16 feeds, plan for additional decoders at the layout stage.

Can it work with third-party cameras and control PTZ cameras?

Yes. The specification lists support for mainstream third-party security devices, ONVIF access and live view of network sources over RTP or RTSP. Operators can control PTZ sources with eight-direction movement, auto-scanning, focal length change, focusing and preset calling. Control can also come from a network keyboard or a serial keyboard. Confirm your specific camera models with SmartRooms Qatar before ordering.

We are fitting out a security control room in West Bay. How many saved layouts can operators use?

The unit stores up to 64 scenes, and you can customise a wall layout and save it as a scene. On the HCP client, up to 100 view groups can switch automatically, and each group can have its own camera locations, scenes and timing. A shift supervisor can therefore keep a perimeter view, a lobby view and a car park view ready to recall. The SmartRooms Qatar team can plan these scenes with you during a free site survey.

Is it suitable for a control room at an industrial site in Mesaieed or Ras Laffan where summer heat is extreme?

The rated working range is -10 °C to 55 °C with 0% to 90% RH humidity, and that is the figure to compare with your room conditions. Summer temperatures in Qatar can exceed 45 °C, so the cabinet or rack holding the decoder needs good airflow and an air-conditioned space. The unit draws less than 15 W. Ask the SmartRooms Qatar team to check the installation location during a free site survey before mounting.

Can a university in Education City feed lecture-hall computers and a camera to the same wall?

Yes. The decoder accepts video from computers and video conference terminals through HDMI input, and it can also take network camera or NVR sources at the same time. The HDMI input supports 4K at 30 Hz, or two 1080p channels at 50 or 60 Hz. Embedded HDMI audio input is supported with 16-bit, 48 kHz or 32 kHz sampling in stereo. Plan the source connections with your AV team, then request a quote for the full setup.

Can a mall in Lusail review recorded footage on its video wall for the security team?

Yes. The decoder can decode recorded video files to the wall and supports playback, where the operator sets the playback status and selects the time to play. It can also capture images from the screen and display them on the wall, which helps a team review an incident quickly. Live views of entrance and car park cameras come from NVRs or other network sources. Request a quote that states the number of feeds and screen sizes.

A logistics operator near Hamad International Airport needs alarm signals on its wall. What alarm connections are available?

The unit has eight alarm inputs and eight alarm outputs, plus one RS-232 port on RJ-45 and one RS-485 serial port. It automatically detects and reports failures such as network disconnection, IP conflicts, illegal access, temperature threshold exceeding and decoding exceptions. A serial keyboard or external system can change windows and scenes. Confirm alarm wiring and the devices to be connected with SmartRooms Qatar during the site survey.

What network connection does the decoder need?

It has one self-adaptive 10/100/1000 Mbps Ethernet port on RJ-45 and supports IPv4 and IPv6 at the same time. It includes a built-in Gigabit switching network and supports NAT. Administrators can access it through a PC client or a Chrome 45 or later browser, change parameters remotely, read system logs and restart the device. Ask your IT team to size bandwidth for the camera streams before installation.

What comes in the box, and what power does it need?

The box includes one decoder, one regulatory and safety manual, one power adapter and one grounding cable. The unit runs from an external 12 VDC supply and draws less than 15 W. Its net weight is 1.12 kg or less, and the dimensions are 220 × 45 × 148 mm. Before ordering, confirm with SmartRooms Qatar that the adapter suits Qatar's 240 V, 50 Hz supply. Request a quote and the team will confirm any extra accessories you need.

Can a government ministry order this decoder with a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and payment by bank transfer, cheque or purchase order. Send the model DS-6901UDI(C), the quantity and the delivery location, and a quotation will usually be issued within one working day. Installation can be planned after a free site survey, with the estimated lead time confirmed on the quotation.
