摘要: A method and system for detecting tampering of a security system component is provided. An analytic alarm indicative of potential tampering with a security system component is received. Data from at least one sensor is received. A computing device is used to analyze the analytic alarm and the data from the at least one sensor to determine whether tampering of the security system component has occurred. A qualified alarm signal is generated when the analysis of the analytic alarm and the data from the at least one sensor is indicative of tampering.

摘要: A system provides ultra-wideband (UWB) positioning. The system exchanges ranging signals at a first rate between a UWB beacon and a UWB tag. The system then determines movement or location information of the UWB tag; and select, based on the movement or location information, a second rate for exchanging subsequent ranging signals between the UWB beacon and the UWB tag. The system then exchanges the subsequent ranging signals at the second rate between the UWB beacon and the UWB tag.
