Overview

The DSMS0115EPI-4K is a Dahua AVoIP encoder that takes one HDMI 2.0 or DisplayPort 1.2 source, encodes it at up to 4K at 60 fps using H.265 or H.264, and sends it over IP to decoders. It adds an SFP fibre port beside its RJ-45 port for network redundancy. Suited to control rooms and operations centres in Qatar moving 4K signals across IP networks.

What the DSMS0115EPI-4K does in an AVoIP system

The DSMS0115EPI-4K is an AVoIP encoder. It takes one HDMI or DisplayPort source, compresses the picture with H.265 or H.264, and places the stream on an IP network so that decoders or a video wall controller elsewhere can display it. Because the signal travels over Ethernet, one network cable can replace a long run of dedicated AV cable, which helps in buildings where cable trays are already crowded.

Resolution, encoding and image quality

The main stream encodes up to 4096 × 2160 at 60 fps, and 3840 × 2160 at the same frame rate is also in the supported list, so 4K sources from workstations, presentation systems or media players keep full frame rate. YUV444 sampling preserves colour detail on small text and fine lines, which suits dashboards and engineering drawings. Lower-resolution sub-stream settings, down to CIF, are available when bandwidth is limited.

Connectivity, redundancy and power

The unit has one 10/100/1000 Mbps RJ-45 port and one 1000 Mbps SFP optical port. Both can be connected at the same time for network redundancy, and losing one link does not drop the device from the network. Power comes from PoE or a 12 VDC, 2.0 A adapter, and both inputs can be used together. Maximum power consumption is 24 W. Supported network protocols include RTSP, RTP, TCP, UDP, HTTP, DHCP and NTP.

Inputs: one HDMI 2.0 or one DP 1.2 source, with one HDMI 2.0 loop output.
Audio: one embedded HDMI or DP audio input, two 3.5 mm audio inputs and one 3.5 mm audio output.
Control: RS-232 and RS-485 ports, plus two alarm inputs and two alarm outputs listed as reserved.

Where it fits in Qatar

A ministry operations room in West Bay might use the encoder to bring a 4K dashboard from a control workstation onto a wall of displays over the existing building network, with the SFP link paired with a second switch for redundancy. On an Education City campus, a lecture hall could feed a teaching display in an adjacent room from a presenter laptop. At an energy site in Mesaieed, a control room could receive a live engineering view from a remote plant area over optical fibre.

What to plan before you order

The operating range is –10 °C to +45 °C with 10% to 95% relative humidity, non-condensing. Qatar summer temperatures can exceed 45 °C, so install the encoder in a ventilated, air-conditioned rack or equipment room rather than a hot ceiling void. It measures 44 × 190 × 130 mm and weighs 0.98 kg net, so check rack or cabinet space in advance. Confirm which switch port will supply PoE, or where a 12 VDC adapter will sit. SmartRooms Qatar offers a free site survey to check cable routes and rack space before the quotation is finalised.

Questions about DSMS0115EPI-4K

What is the Dahua DSMS0115EPI-4K used for?

It is an AVoIP encoder that converts one HDMI 2.0 or DisplayPort 1.2 source into an IP stream, so the picture can be shown on decoders or a video wall elsewhere on the network. It suits organisations that want to move 4K screens over existing Ethernet instead of running dedicated AV cable between rooms, such as control centres, universities and corporate campuses in Qatar.

What inputs and outputs does it have?

It has one HDMI 2.0 input or one DisplayPort 1.2 input, chosen according to the source. One HDMI 2.0 loop output passes the input to a local display. There is also one 3.5 mm audio output, two 3.5 mm audio inputs, an embedded HDMI or DP audio input, three USB ports and an RS-232 port for maintenance and debugging.

Does it handle 4K at 60 frames per second?

Yes. The main stream encoding list includes 4096 × 2160 and 3840 × 2160 at 60 fps, with H.265 and H.264 compression and YUV444 colour sampling. H.265 generally reduces bitrate for a similar picture, which helps when several streams share the same switch.

How does the network redundancy work?

The encoder has one RJ-45 port and one 1000 Mbps SFP fibre port, and both can be used at the same time. Disconnecting either interface does not affect the device's network connectivity, and hot standby is supported. This suits buildings where a fibre backbone and a copper edge switch both serve the same room.

Can it be powered without a separate adapter?

Yes, it can run from PoE, and it also accepts a 12 VDC, 2.0 A adapter. Using both gives power redundancy. Power consumption is up to 24 W. Confirm that your switch port supplies PoE before choosing it as the power source, and plan the adapter location if you use 12 VDC.

Is it suitable for a hot equipment room in Qatar?

The operating range is –10 °C to +45 °C with 10% to 95% relative humidity, non-condensing. Qatar summer temperatures can exceed 45 °C, so keep the unit in a ventilated, air-conditioned rack or room. SmartRooms Qatar can review the installation location during a free site survey before you order.

Can it add text or crop the input picture?

Yes. It can overlay Chinese and English subtitles and time information on the input signal, with adjustable font colour, size and coordinates. It can also crop the input so only a user-selected area is shown. The source data does not list Arabic subtitles, so confirm any Arabic text needs with the SmartRooms Qatar team before ordering.

How could a ministry operations room in West Bay use it?

A control workstation can send a 4K dashboard onto the building network, and the encoder can deliver it to a video wall controller on another floor. The SFP and RJ-45 ports keep the device online if one link fails, and its 2-inch screen shows the device name and IP address for quick checks during handover between shifts.

Is it useful for a lecture hall in Education City?

Yes, for sending a presenter laptop or classroom PC signal to a teaching display in another room over the campus network. Its loop output can feed a local screen at the same time. Choose H.264 where receiving decoders need broader compatibility, and check that the decoder supports the codec you select before requesting a quote.

Can a control room at an energy site in Mesaieed use it?

A control room can receive a live engineering or process display from a plant area over optical fibre through the SFP port, with RJ-45 as a second path. With an operating range of –10 °C to +45 °C, the unit should sit in a conditioned panel room. Cable routing and enclosure details can be agreed during the site survey.

Would it suit a hotel or event venue in Lusail?

Yes. A ballroom or conference suite in Lusail can distribute a presentation from a central rack to several screens or a video wall in other rooms over Ethernet. Remote reboot, firmware upgrade and default-setting operations can be performed over the network, so routine changes do not require someone at the rack.

What should a school in Al Wakrah check before ordering several units?

Confirm the number of sources and whether each uses HDMI or DP, and check that each room has a PoE port or a 12 VDC supply. Then request a quotation from SmartRooms Qatar, usually issued within one working day. Schools can issue a purchase order (LPO), and a free site survey can check cable routes and rack space before installation.
