Abstract:

An alarm filter () for use in a security system () to reduce the occurrence of nuisance alarms receives sensor signals (S-S, S) from a plurality of sensors () included in the security system (). The alarm filter () produces an opinion output as a function of the sensor signals and selectively modifies the sensor signals as a function of the opinion output to produce verified sensor signals (S′-S′).

International Classification:

B66B 1/34

US Classification:

187392, 187316

Abstract:

An elevator control system () provides elevator dispatch and door control based on passenger data received from a video monitoring system. The video monitoring system includes a video processor () connected to receive video input from at least one video camera (). The video processor () tracks objects located within the field of view of the video camera, and calculates passenger data parameters associated with each tracked object. The elevator controller () provides elevator dispatch (), door control (), and security functions () based in part on passenger data provided by the video processor (). The security functions may also be based in part on data from access control systems ().

International Classification:

H04N 7/18

US Classification:

348143, 348E07085

Abstract:

The present invention describes a system and method for surveillance cameras that maintain proper mapping of a mapped region of interest with an imaged region of interest based on feedback received regarding the current orientation of a surveillance camera. The system or method first determines the location of the imaged region of interest within the surveillance camera's imaged current field of view based on mechanical or imaged feedback, or a combination of both. The system or method then remaps the mapped region of interest within the surveillance camera's imaged current field of view such that the mapped region of interest is coextensive with the imaged region of interest.

International Classification:

H04N 17/00

US Classification:

382103, 348180, 348E17001

Abstract:

A video content analysis (VCA) system generates an output regarding a detected condition that provides an indication of a confidence level regarding the detected condition. One example VCA system determines whether a first characteristic of a detected object in a field of vision of the video content analysis system satisfies a first criterion. If so, a first signal is generated under selected conditions. The VCA system also determines whether a second characteristic of the detected object satisfies a corresponding second criterion. If so, a second, different signal is generated if the first and second criteria are satisfied. The first and second signals indicate respective, different confidence levels that an event has occurred. A disclosed example includes a VCA as part of a security system.
