The E-Link 4K 120M HDMI KVM Extender over IP is a device designed to extend HDMI signals, along with USB and IR control, over an IP network. It can transmit signals over distances of up to 120 meters (approximately 393 feet) using Cat5e/6 cables, allowing for high-definition video, keyboard, video mouse (KVM), and infrared control signals to be transmitted to a remote location.

Here's a quick breakdown of what this device offers:

Key Features:

1. 4K Support:

   • The extender supports 4K resolution at 60Hz, providing high-quality video transmission, which is ideal for applications requiring high-definition video, such as digital signage, video walls, or even remote workstation setups.

2. Long-distance Transmission:

   • 120 meters of transmission distance via Ethernet cables (Cat5e/6), which is quite a good range for most setups. This is achieved using an IP-based network connection.

3. KVM (Keyboard, Video, Mouse):

   • It allows you to control your remote PC or device with USB keyboard and mouse while receiving the video output over the same cable. This is useful for remote management in server rooms, control centers, or other environments where direct access is difficult.

4. IR Control:

   • The inclusion of IR (infrared) control means that you can control HDMI sources (e.g., TVs, media players, etc.) remotely, such as turning a TV on/off or changing channels. This is ideal for applications where the HDMI source is out of direct line of sight, like in AV setups or home theaters.

5. Networking:

   • IP-based system (Ethernet or LAN) means you can extend the signal over your existing network infrastructure. This makes it easier to set up and reduces the need for long, dedicated cables.

6. USB Support:

   • USB functionality is crucial for scenarios like remote desktop control, where you need to use a keyboard and mouse with a remote PC or server. USB peripherals can be transmitted seamlessly.

Applications:

• Digital signage in retail, airports, or conference rooms.
• Remote workstation setups for control rooms, servers, or data centers.
• Home theater systems where remote HDMI devices need to be controlled.
• Classrooms and meeting rooms for flexible, high-quality presentations.

Installation:

• Easy to install with basic network configuration. You just need the transmitter (to connect to your HDMI source and USB peripherals) and the receiver (to display video and handle inputs). Typically, a simple Ethernet switch or network is all that’s required.
