Russian procurement documents rarely use the phrase “video wall”. The term that appears in tender specifications is система отображения информации коллективного пользования — literally a collective-use information display system. The distinction is not cosmetic: the tender term names the whole system rather than the screens, and a bid written in the wrong vocabulary reads as an incomplete answer.
What the term covers
Four groups: the display surface (LCD panels or LED cabinets with mounting), the controller — which today usually means a server rather than a dedicated box, the control software with its operator roles and layouts, and the sources being displayed. A quote that prices only the first group answers a different question than the one the specification asked.
Writing the requirement
Specify capability, not a model: number of video outputs and their resolution, source types and counts, operator roles and audit requirements, operating system, and whether the deployment must run without outbound connectivity. Naming a vendor model ties the purchase to a single supplier and makes the justification harder to defend.
For a significant critical-infrastructure facility the display system inherits the facility’s significance category along with its security requirements — see the import-substitution guide for how that plays out in practice.
