DIGITUS DS-55318 Wireless HDMI Extender Set, AV Transmitter and Receiver, 50 m Range, 1080p Resolution at 60 Hz

The DIGITUS DS-55318 Wireless HDMI Extender Set provides a reliable solution for transmitting audio and video signals without the hassle of long cables. Comprising an AV transmitter and receiver, this system supports Full HD 1080p resolution at 60 Hz over a maximum transfer distance of 50 meters in open spaces. Utilizing wireless connectivity through the 5 GHz band, it establishes a stable point-to-point connection using IEEE 802.11ac standards. The compact design allows for discrete placement behind displays or projectors, making it an efficient tool for dynamic environments.

Advantages

This wireless HDMI extender eliminates the need for complex cable routing, significantly reducing installation time and clutter in professional and domestic settings. Automatic pairing simplifies the setup process, enabling the device to select the most optimal Wi-Fi channel for stable performance. Support for Plug and Play operation ensures that users can connect the transmitter and receiver and begin projecting immediately without installing additional software. Data security is maintained through WPA2 protocols and AES 128-bit encryption, safeguarding transmitted content against unauthorized interception. Power can be supplied flexibly through either the HDMI port or the micro-USB connection, accommodating various source devices.

Suitable for

• Connecting a laptop to a projector in a meeting room or conference facility
• Spontaneous presentations in office environments without fixed cabling
• Home entertainment setups for temporary or flexible screen sharing
• Classrooms and training sessions requiring mobile video transmission

When it may not be suitable

This wireless extender may not perform adequately in environments with heavy physical obstructions, such as thick concrete walls, metal partitions, or multiple glass barriers, which significantly reduce the effective transmission range. It is also not designed for ultra-low-latency applications like competitive gaming or professional video editing, as a transmission latency of approximately 120 milliseconds is to be expected.

Key specifications

• Wireless connectivity via 5 GHz IEEE 802.11ac 2T2R
• Maximum resolution of 1920 x 1080 pixels at 60 Hz
• Maximum transfer distance of up to 50 meters with unobstructed line of sight
• Audio support for stereo 16-bit at 48 kHz
• WPA2 security protocol and AES 128-bit encryption
• Micro-USB and HDMI power input options requiring DC 5V/0.5A
• Compact dimensions of 8.3 x 3.2 x 1.3 cm per unit

How to use

To set up the system, plug the transmitter unit into the HDMI output port of your source device, such as a laptop or media player, and connect the receiver unit to the HDMI input port of your display or projector. Power both units either by utilizing the connected HDMI port if it supplies sufficient current or by using the included micro-USB cables connected to an external power source. The devices will automatically pair and establish a wireless connection through the optimal Wi-Fi channel. Once the LED status indicator shows a steady connection, the video and audio signals will transmit automatically from the source to the display screen.

What to consider before purchase

• Verify that the line of sight between the transmitter and receiver will be relatively clear of dense walls or metallic objects
• Check if the HDMI port on your source and display devices can supply at least 0.5A of power if you prefer not to use auxiliary USB cables
• Evaluate whether a latency of roughly 120 milliseconds is acceptable for your specific application
• Confirm that your maximum required resolution does not exceed Full HD 1080p at 60 Hz

Usage recommendations: Position both the transmitter and receiver in open areas with minimal physical interference to achieve the maximum advertised 50-meter range. If unstable transmission occurs due to obstacles or interference, reduce the physical distance between the two units and ensure that power supplies consistently deliver the required 0.5A.
