To monitor objects and site areas at risk, measurements are performed via motorised total stations to signalling measuring points via prisms. To cover larger areas, arbitrary numbers of total stations can together be linked into one system. Laser systems for on-line distance measurements are also available for special applications. In each case, the measurement intervals can be chosen freely.

Instrument for automatic laser distance measurements

All the modern communication technologies such as radio, W-Lan or GSM modems are available for data transmission. Data can be displayed in real time on a PC. It is also possible to trigger automatic alarms when limits are exceeded.
