Remote controls are the part of a display or projector that leaves the room: replacement remotes for the models in service, and the universal and presentation remotes that keep conference rooms and classrooms running when the original walks away. A missing remote idles equipment as effectively as a fault.
Replacement remotes are model-matched - order by the display or projector's exact model number, since functions like input selection and menu access often exist only on the correct remote. For shared spaces, the practical policy is a spare per room type plus a small central stock, because remotes are the most-lost item in any AV estate and the cheapest to stage ahead of need. Presentation remotes are a separate purchase judged by range and the presenter's software. Tethering or mounting remotes in public rooms extends their tenure considerably. COLAMCO supplies replacement and presentation remotes alongside the display fleets they drive for business, government, and education facilities.
