7.1.2
Hardware/Software
RockSpot system is designed to operate continuously 24/7, but it may become temporarily unavailable due to
hardware/software failures. In case of unavailability, the system is designed to provide the user with a warning message
by e-mail and SMS. In these cases, monitoring data and automatic alert activation addressed to Decision Maker are not
available until the instrument is repaired. It is user responsibility to check such warning messages regularly and to take
appropriate actions accordingly. This notification mechanism may fail because of hardware or network failure.
7.1.3
Alert rules setup
Automatic alert activation by RockSpot system, to be addressed byDecision Maker, requires an appropriate setting of
the alert rules, with the definition of the areas concerned, alert levels and type of alert devices to activate. Incorrect
alert rules setup may lead to missing or incomplete alert activation. The setup of alert rules is solely under user
responsibility, based on his knowledge of the specific application features.
7.1.4
Data Quality
In case of extreme weather conditions radar data quality may drop below the required minimum threshold. In this case
the user is notified by an alert, and the monitoring and event detection will not be available. Consequently, SFE alerts
will not be triggered. This notification mechanism may fail because of hardware or network failure.
7.1.5
False alarms & Missing detections
Like any other radar device, RockSpot may be subjected to false positives (detections triggered in the absence of a real
SFE or unwanted detections), and false negatives (missing detections). IDS GeoRadar shall not be liable in the event of
such false positives and missing detection. In radar-based systems false positive probability depends on noise
characteristics at the receiver and the chosen threshold, and may vary on the specific scenario. The probability of false
negatives depends on the power of backscattered signal from moving object, which in turn depends on various factors
