Resolution Frequency Patch Connections Cable Type Distance
1920x1200 60Hz 0 CAT7a 50 meters
1920x1200 60Hz 0 CAT6a (shielded) 50 meters
1920x1200 60Hz 2 CAT6a (shielded) 40 meters
1920x1200 60Hz 2 CAT7a 40 meters

Note: Distances are achieved using single lengths of trunk/bulk cable. For each break/patch connection reduce distance by 5 meters. Preferably patch cables should be of type CAT7a and less than 2 meters. Patch cables over 2 meters must be CAT7a.

Product features part 1

Proof of Display via IP network

The unit determines if the entire system is operating correctly and video is visible on the monitors. It can detect if video is present from the player and whether the cables to the monitors are attached and the monitor is turned on. This information is available by an IP socket thus allowing remote diagnostics and integration into content management systems.

Source Failover

The unit can be set to detect that a video stream is present at the input. The unit can be set to automatically switch over to the second video input if the primary fails.


Security on the web interface is by HTTP digest authentication (RFC 2617) with username and password as requested information.

API for 3rd Party Integration

The API documentation to control and receive data from the unit is provided with the system.

Digital audio

Supports 8 channels of HDMI audio.

Perfect HD Digital Video

The ALDV104 uses an uncompressed video system where every frame is sent without loss with resolutions up to 1920 x 1200@60Hz (WUXGA) including 1080p, 720p and 480p resolutions.

50 meters over a single CATx cable

Video, audio and power all pass along a single CATx cable, providing up to 50m of extension. Distance can be dependent upon CATx cable types and the number of connection breaks for patch panels and wall plates. See overleaf for details.

Dual Head Extension

With two inputs, the system is suited to extending and splitting dual head systems.

Highly energy efficient - no external power supplies are required

The receivers are designed to be highly power efficient, using less than an eighth of the power required by competing systems. Power is supplied along the CATx cable meaning the support infrastructure required is minimal.

EDID Management

The system has intelligent EDID management allowing the true characteristics of the monitor to be passed back to the computer.

Plug and Play

The DV104T is delivered in a zero config state so you can plug and play. There is no need for additinal drivers or software.
