The causes of false alarms vary and include: User error User error accounts for some 50% of all false burglar alarm calls. Most often, these false trips are caused by a new or improperly trained employee trying to arm or disarm the system. Additionally, cleaning crews, maintenanc...

What Causes False Alarms? Within video surveillance systems, there are two types of false alarms that enterprises should be concerned about: false positives and false negatives. The cause of false positives and false negatives ultimately comes down to the accuracy of the underlying facial ...
The false positive rate (FPR) is a measure of the proportion of positive cases that wereincorrectlyidentified or classified as positive in a test. Or, in layman’s terms, false alarms. False Positive Rate can be used to measure binary context problems. Among these are predictions, detection ...
In contrast, the false negative defines an IDS as being unable to detect correct instances under certain circumstances. Soft computing, Artificial Intelligent, and fuzzy logic techniques are applied to minimize false alarms while keeping the high detection of accuracy. The effectiveness of these ...
Another common mistake is to send alarms from the control system (BMS, DCS or SCADA) to create work orders (or job requests) directly in the CMMS: sometimes thought as ‘condition-based maintenance’ it results in a purely reactive handling [...] sivecochina.com 另一个错误案例就是由...
False alarms refer to the phenomenon where the radar incorrectly identifies non-targets as targets during the detection process. The control of false alarm rate (FAR) has consistently been a key concern in the domain of radar target detection. Early non-coherent, short-term cumulative detection me...
[71] evaluated a data-driven hybrid information fusion algorithm for cyber-physical intrusion detection, which uses network and power sensor data to reduce false alarms. Since the hybrid information fusion algorithm involves multiple parameters and models, parameter tuning is difficult. Zhao et al. [...

To further analyze the false positives, as they can lead to unnecessary action such as triggering alarms, we measure the precision of each model. Similarly, recall is measured as it is crucial for a false data injection attack; missing an attack (false negative) could have severe consequences ...
