Name: Dahua DSCON3000-4U Multi-screen Controller for Video Walls
Brand: Dahua
SKU: dahua-dscon3000-4u
Availability: Discontinued

Overview

The Dahua DSCON3000-4U is a discontinued multi-screen controller for video walls, built in a 19-inch 4U ATCA chassis with 12 pluggable card slots. It accepts HDMI, DVI-I, 3G-SDI and CVBS inputs, decodes up to 160 channels at 1080P, and can splice up to 80 LCD displays. Organisations in Qatar that already run this model, or need a replacement for a control room wall, can request a quote for a current equivalent.

What this controller does in a video wall

The DSCON3000-4U is a multi-screen controller from Dahua, and the manufacturer has discontinued it. It sits in a control room or equipment rack, takes analogue and digital video sources, decodes them and routes them to a wall of LCD displays. Operators can splice one picture across several screens, zoom into a feed, merge or overlay sources, and move windows around the wall. Control is possible from a PC client, a local interface, a network keyboard or an iPad.

Chassis, card slots and expansion

The unit is a 4U, 19-inch ATCA industry box with a passive rear panel and a PCI-E bus. Its 12 slots hold two main control boards and ten video function boards, so one chassis can carry up to ten input cards and up to ten output cards. The pluggable card design lets engineers add or swap modules rather than replacing the whole controller. Redundant power is an optional upgrade, and the fan adjusts its speed to the temperature.

Inputs, outputs and decoding capacity

Input cards cover HDMI with HDCP support, DVI-I, 3G-SDI and a 32-channel CVBS card. The chassis also accepts network video from IP cameras, NVRs and similar devices over TCP, UDP, RTP and RTSP. Output cards include 8-channel HDMI 1.3, 4-channel 3G-SDI and 8-channel HD-SDI. A fully configured unit decodes 160 channels at 1080P or 640 channels at D1, and its IP matrix handles 1024 IP inputs. Two gigabit RJ-45 ports carry matrix control and preview traffic.

Where it fits in Qatar

A ministry operations room in Doha or a utility monitoring centre in Ras Laffan might need CCTV, IP camera and SDI feeds on one display wall, so that staff can check several sites at once. In a university control centre at Education City, the splicing function can stretch a single lecture-hall or event feed across a large screen during conferences. A hospital command room, or an operations team near Hamad International Airport, could use the 80-display splicing capacity to build a live status wall, with the final layout depending on the number of outputs fitted.

Planning power, cooling and rack space

Rack depth: plan for 437 mm; the box measures 482.6 × 437 × 177 mm.
Weight: up to 20 kg fully configured, so check the rack load rating.
Power: 90W minimum and 360W fully configured, with a listed input of 115V to 230V at 47Hz to 63Hz.
Environment: -10°C to +55°C at 10 to 90% relative humidity.

The listed input range does not extend to Qatar's 240V, 50Hz supply, so confirm power compatibility before ordering. Rack rooms should be air-conditioned, particularly in summer when outdoor temperatures in Qatar regularly pass 45°C. The SmartRooms Qatar team can check the room during a free site survey before installation.

Requesting a quote for a replacement

Because Dahua has discontinued the DSCON3000-4U, owners planning an expansion or repair should review the support still available and compare current options. Send SmartRooms Qatar your input and output counts, display count, cabling and rack details. We will prepare a quotation for a current equivalent or a compatible replacement, usually within one working day. Purchase orders and government tenders are accepted. Request a quote today.

Questions about DSCON3000-4U

Is the Dahua DSCON3000-4U still sold by the manufacturer?

No. Dahua has discontinued this model, so this page covers a product that is no longer in production. If your control room already runs a DSCON3000-4U, or you are planning an expansion, SmartRooms Qatar can review your input count, display count and rack space, then quote a current equivalent or compatible replacement. Quotations are usually issued within one working day.

What is the DSCON3000-4U used for?

It is a multi-screen controller for video walls. It takes analogue and digital sources, decodes them and routes them to LCD displays, with splicing, zoom, merge, roam and overlay functions. Operators can run it from a PC client, a local interface, a network keyboard or an iPad. It suits monitoring rooms where several camera and video feeds must share one wall at the same time.

How many screens can one controller drive?

The data gives a splicing limit of 80 LCD display units. Actual capacity depends on the output cards fitted, because the chassis takes up to ten output cards across its ten video function slots. A control room in Doha planning a 16-screen or 24-screen wall should confirm the card layout during a free site survey before ordering, so the chassis is sized to the wall.

How many video channels can it decode?

A fully configured chassis decodes 160 channels at 1080P or 640 channels at D1. One decoding output card is rated at 16 channels of 1080P at 25fps and supports H.265 streams. In its IP HD matrix mode, the system handles 1024 IP inputs, with 160 channels at 1080P, 320 channels at 720P or 640 channels at D1.

Which input types can I connect?

Input cards cover HDMI with HDCP, DVI-I, 3G-SDI and CVBS. The CVBS card takes 32 channels at 960H or D1. The chassis also accepts network video from IP cameras, NVRs and similar devices over TCP, UDP, RTP and RTSP. List your sources and camera types, then match them to the card mix before you order.

Does it support 4K sources?

The 2-channel HDMI 1.4 input card accepts 4K sources, and the decoding card can output 3840 × 2160 at 30fps on its HDMI 2 and HDMI 3 ports. Most channel ratings in the data are for 1080P, so tell us which sources are 4K before we size the system for your wall.

Can it sit in a standard rack in a control room?

Yes. It is a 4U, 19-inch box measuring 482.6 × 437 × 177 mm, and it weighs no more than 20 kg fully configured. Plan at least 437 mm of rack depth and check the rack's load rating. Install it in an air-conditioned room, since outdoor temperatures in Qatar often exceed 45°C in summer, and the unit's operating range tops out at +55°C.

What power does it need, and is redundancy available?

Redundant power is an optional feature. The listed input is 115V to 230V at 47Hz to 63Hz, which does not extend to Qatar's 240V, 50Hz supply, so confirm the power arrangement with SmartRooms Qatar before ordering. Consumption is 90W for a minimum system and 360W for a full configuration. Size any UPS and circuit around the full-load figure.

Can I control it remotely?

Yes. You can reboot, upgrade and restore default settings remotely. The unit has two gigabit RJ-45 ports for matrix control and preview, four RS232 ports and one RS485 port for hardware control, plus three USB 2.0 ports and one USB 3.0 port. A university IT team in Education City could manage the wall from a central office without entering the equipment room for routine changes.

Would it suit a hospital command room or an airport operations wall?

It can suit a large operations wall, since splicing supports up to 80 LCD units and the matrix accepts camera and IP sources. Before a hospital command room or an operations team near Hamad International Airport commits to a design, confirm input cards, output cards, cabling and redundancy. Because the model is discontinued, ask for a current equivalent alongside the layout review.

What should I check before replacing an older controller?

Record your existing input and output card types, the number and resolution of displays, the cabling between sources and the controller, and the rack space available. Also note the power and cooling in the room. A free site survey from SmartRooms Qatar can confirm these details. Send the list with your request, and the quotation will reflect your current wall rather than a generic configuration.

Can SmartRooms Qatar supply and install a replacement?

Yes. SmartRooms Qatar supplies the equipment, delivers to all eight municipalities of Qatar, and offers professional installation. We accept purchase orders and government tenders, and payment by bank transfer or cheque. Because a replacement may use a different chassis or card layout, the installer will check cabling and power before work starts. Request a quote with your details.
