Monitoring system i.e. video-monitoring system, for e.g. internal area such as office, has camera arranged at carrier, which is aligned to be moved on both sides of carrier within guiding tube by pressure differences

摘要

The system has a central control device, a camera (11) movable along a guide and determining image data, and a monitor for the image data. The guide is designed as a partially optically transparent and hermetically closable guiding tube (3), which is provided with valves (6) to feed and/or take the compressed air in the tube that is made of glass or plastic. The camera is arranged at a carrier (10), which is aligned to be moved on both sides of the carrier within the guiding tube by pressure differences. A weight (12) is provided at the carrier and aligns the carrier due to the gravity force.
