Empty shelves, a hole in the ceiling, and a ladder left behind was all that police found on 14 January 2008 after a burglary from above into a wholesale market in Suhl (Thuringia). The haul: cigarettes, alcohol, and rolls of coins. Other favorite stolen goods are electronic devices. In January 2008, an electronics store in Ludwigshafen (Rhineland-Palatinate) had to suffer that experience just as did a special electronics store in Bensheim (Hesse) in June 2008 and a cell phone store in Klagenfurt (Carinthia, Austria) in November 2008. However, burglars will not even shrink from breaking into office buildings and warehouses containing frozen food, brand-name clothes, or non-ferrous metal – particularly if they can get their hands on relatively substantial amounts of loot relatively easily. What facilitates their “work” is the fact that due to cost considerations, many warehouse buildings in particular feature a very inexpensive architectural fabric, e.g. sidewalls made of gypsum board, or roofs made of thin sheet metal. As well, light domes, skylights, and ventilation flaps on the roof often constitute “involuntary helpers.” Effective remedies are possible – with the assistance of laser measurement systems covering facades and flat roofs on the outside as well as walls, floors, or ceilings inside with a complete and impenetrable safety screen.
Laser measurement provides functional surveillance protection
In the scope of application related to building security as well as site protection, laser measurement systems usable horizontally and vertically, such as the new LMS120 with floating relay output, e.g. for switching on one camera, provide a maximum degree of detection reliability. A certified version – the LMS120 Security – is in the pipeline. Due to its high angular resolution, the system produces a safety veil that is “woven” so finely that even a drill bit breaking through a wall is detected immediately and reliably. The same applies to the uninvited guest from above: Even if that “shady character” is indeed wearing black, thus generating only minimal light reflectance for the laser measurement system, he or she is detected unfailingly by means of the double-pulse evaluation method – even in rain, fog, or snow, since the outdoor laser scanners work accurately and dependably in poor weather conditions as well. Using the integrated parameterization and evaluation software, one can designate in each device up to ten monitoring fields per mouse click. These may be up to 18 m deep and can be defined freely within the device’s detection range; therefore, the monitoring fields do not necessarily have to begin at the scanner. Moreover, these fields can be adjusted later as desired, e.g. to side walls, supporting pillars, and other architectural features.
Protected reliably against manipulations
Besides the mounting location – frequently under the roof and reachable only by ladder, the coded access to the device, which means parameters can be changed only by authorized technical staff, as well as the metrological referencing to stationary contours constitute effective protection against manipulations.
The LMS100 – just like the LMS111 outdoor variant – are reliable surveillance systems for facility management; once installed, they become active after closing time only in case of a break-in.
