US Patent 9767680 Abberation detection technology

In some implementations, techniques are described for detecting abnormal installations in a property monitored by a monitoring (e.g., security) system. For instance, an aberration engine may be used to detect an abnormal sensor or system installation within a property based on comparing detected installation data against local installation patterns of local providers within a certain proximity to the property. In some examples, the attributes (e.g., installation time, components used, number of tests performed, etc.) of a monitoring system installation, including installation of components of the monitoring system, may be compared to average installation times of other nearby installations to detect abnormalities in the installation.
