Choose a KVM extender that matches the source and display resolution, such as 1080p or 4K, and confirm that its USB implementation supports the connected keyboard, mouse, touchscreen, webcam, or other peripherals. Then match the extender to the required distance and installed cable, with options supporting Cat 5e or Cat 6 runs around 50 meters and others extending 4K signals up to 100 meters over Cat 6a or Cat 7, while HDBaseT or IP-based designs can support additional control, audio, Ethernet, or Power over Ethernet features.

KVM extenders can use a single Cat 5e or Cat 6 cable, while some models also support Cat 6a or Cat 7 cabling for longer-distance or higher-bandwidth installations. Depending on the design, they can operate as a direct point-to-point connection or use Ethernet and IP network connections, with some supporting 1Gb Ethernet and Power over Ethernet.

Point-to-point KVM extenders connect one transmitter directly to one receiver, often using a Category cable, while HDBaseT describes the transport technology that can carry video, USB KVM, audio, control, Ethernet, and power between those endpoints. IP-based KVM extenders encode the signals for transmission over an Ethernet network, which can support multiple sources and displays but requires network planning, bandwidth management, and compatible network equipment.

KVM extenders carry video, audio, and keyboard, video, and mouse (KVM) control between a centralized computer, security NVR or DVR, or AV source and a remote display over Category cable or a network. This lets installers place equipment in a rack, equipment room, or other secured location while providing remote access for monitoring, control, presentations, and interactive use in residential or commercial spaces.
