Two machines under one word. A gobo projector throws a single fixed mark — a logo on a pavement, a pattern on a ceiling — and runs all night on 15 W. A mapping rig covers a whole surface in moving image, and has to be built for that surface: the content is cut to those windows and that brickwork, and does not transfer to another wall.
Gobo and logo projectors that brand a surface, and interactive projection and mapping systems that wrap an object or a room.
That is a video projector, and it sits with the screens — see Screens & projectors, beside the video walls and commercial TVs it stands in for.
Both — outdoor work needs an IP-rated housing and more brightness. Tell us the site and throw distance and we'll spec it.
Yes — a gobo is cut from your logo, and mapping units play your own media.
