iv. Monitoring Products include specific “Operational” software with data processing which
may give outcomes/results for helping User in the monitoring of “the stability conditions”
of a specific area. We remind however that the setting of the alarm thresholds is uniquely
an expert User’s responsibility and that this setting must be done according to the accurate
knowledge of the particular geological context.
v. Nevertheless, (even though the radar technology employed by Monitoring Products, is
deemed among the most reliable for the monitoring of instable slopes) IDS GeoRadar s.r.l.
has the obligation to remind the Users that the technology used by Monitoring Products
transmits and receives an electromagnetic signal that by its nature is influenced by many
factors such as: the parameters introduced by the User/s, the distance, the ground
material, the surface roughness and the electromagnetic wave incidence, which may
distort its outcomes, thus giving rise to false or missing alarms.
vi. In particular the following aspects must be considered when working with Monitoring
Products:
o Due to the very short time of activation and minimum deformation before a sudden
rockfall event, it may be not always possible to generate proper alerts prior to the
collapse.
o Even if the technology used provides state-of-the-art performance in terms of spatial
resolution and accuracy of measurement, movements affecting portions of the slope
below the radar resolution could go beyond the minimum detectable movement.
