In recent weeks we have successfully modernised and completed the security and monitoring technology of production process at a wood treatment plant in the Upper Liptov region. We could perform the replacement and expansion of the video camera system only when the production lines were shutdown. We did our work in a strictly limited time period, and production could continue with the new monitoring system. The most difficult part of the order was done directly in the production hall – the sawmill – where we worked in a highly dusty environment.
