elemetrics camera support systems offer the option of automated Collision Avoidance, whereby a trolley or ceiling mounted camera can be set up to automatically avoid unwanted collisions with physical obstructions. Using newly designed 2D XY scanners/sensors, the warning light system will go on solid when the equipment is in motion and will blink if there is an obstruction. The brightness of the light is adjustable, and the scanners can be configured for up to 5 meters.
