What is a KVM Extender and Why Do I Need One?

What is a KVM extender?

A KVM extender is a device that increases the distance from a keyboard, monitor, and mouse to a computer. USB cables for keyboards and mice can only give you reliable connections up to 5 meters, so a KVM extender is a great solution for transmitting these connections over substantially long distances. The main purpose of a KVM extender is providing point-to-point computer extension and access to computers from remote locations. It consists of two units: a transmitter (Tx) that connects to the source (e.g., computer) and a receiver (Rx) that connects to the devices (e.g., keyboard, monitor, and mouse).

Why do I need a KVM extender?

A KVM extender can benefit many applications in almost any environment like schools, hospitals, call centers, offices, and retail stores. Here are a few common examples of where you would use a KVM extender.

Improve the Workspace

Reduces clutter, noise, and heat from the work area by relocating employees’ computers in a single, centralized location. This frees up desk space at work stations by removing clunky system units, making it nice and tidy and creating a computer-free work area.

Security and Data Protection

Protects computers from damage and technical failures. Places like industrial environments can have hazardous dust and debris, so keeping the computer in a remote location will keep it unharmed.

A KVM extender can also protect your computers from unauthorized tampering in establishments frequented by the public like libraries and internet cafes. Shopping malls or lobby areas can have interactive touchscreens where you want to protect the computers driving these screens by placing them far away in a secure area.

Live Events and Presentations

During live events or presentations, the speaker could be at the podium with a big screen for the audience to take in visual information. However, the podium is typically located at a distance from the computer. A KVM extender will be able to transmit audio, video, and control signals from the computer allowing the speaker to control the screen's content.

A Pair of Great KVM Extender Solutions

Depending on what your needs are, BZBGEAR offers two KVM extenders that extend HDMI and USB signals over a single CAT cable. They both offer Power over Cable (PoC) allowing either the transmitter or receiver to power up both units. Convenient if power only exists on one end of your setup.

BG-HDKVM-50 (Tx and Rx)

The BG-HDKVM-50 extends HDMI and USB signals 50 meters (164 feet) over a CAT5e/6 cable with zero latency. It supports 1080p@60Hz and HDMI 1.4b and is HDCP 1.4 compliant.

BG-UHDKVM-100 (Tx and Rx)

The BG-UHDKVM-100 extends HDMI and USB signals 100 meters (328 feet) over a CAT6a/7 cable. It supports 4K@60Hz (4:4:4) at 18Gbps and HDMI 2.0. It is HDCP 2.2 / 1.4 and DVI 1.0 compliant.

Both KVM extenders support audio such as LPCM, Dolby Digital, and DTS. But the BG-UHDKVM-100 allows you to de-embed audio as well as supports Audio Return Channel (ARC).
