The here discussed infrared camera-based monitoring system observes the temperatures of concentrated solar power plants to avoid damages. Besides, it allows to control the temperature-relevant parameters of the plant like salt flux and heliostat positioning and therefore needs to be designed with a high-level fallback strategy. In this presentation possible influences by environment, plant-specific behaviors, geographical situation and failure scenarios will be discussed and the solutions described. These include the infrared-optical measurement adaptation, the mechanical installation, the electrical and data network design and finally the software-based algorithms to ensure a 24/7 reliability under all possible conditions defined by the mentioned influences.
