Specific Industries

Examples of how Adder Technology fit into a number of specific industries

Digital Signage

Digital signage is a growth industry, using the flexibility of motion graphics to deliver powerful advertising messages and information tools. The most stable form of signage system relies upon central playout devices delivering video signals via CAT5 or higher cable. The AdderLink AV series of Digital Signage solutions have been specifically designed to deliver bright, accurate video with full saturation and crisp digital audio up to 300 meters from the signal source.

Broadcast. Media and Post

KVM and extension technologies are used commonly throughout broadcast infrastructure. Adder Broadcast KVM and Extension devices can be found from content origination and post production through to control room scenarios. ADDERLink extension products are designed specifically to carry video and audio signals in a pure manner without loss of signal quality. Extenders allow you to relocate noisy machinery, or even share (using KVM) the expensive machinery found in busy production environments. By relocating PC's and similar equipment, the machines can be kept in an environment suited to their optimal running performance, further extending the life of the tools you rely upon.
