Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for reducing irrelevant alerts and/or network bandwidth usage from Internet of Things (IoT) cameras through the intelligent filtering out of video data. An example embodiment operates by receiving video data from an IoT camera. The embodiment further generates an ignore mask based on the video data, wherein the ignore mask specifies one or more regions in a video stream from the IoT camera that cannot trigger an alert. The embodiment then transmits the ignore mask to the IoT camera. The embodiment then receives the video stream from the IoT camera in response to transmitting the ignore mask to the IoT camera. The embodiment then determines that the video stream is associated with the alert. The embodiment may then transmit the alert to a user device in response to the determining.

Abstract: Disclosed herein are system, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for reducing and/or eliminating false positive alarm triggers. Detector devices positioned throughout an environment scan for known events that are likely indicative of an alarm condition. A source device that may generate such a sound or image may imprint a fingerprint on to the event that can be detectable by the detector devices but is imperceptible to humans. Additionally, the detector devices may use directionality and known locations of source devices to determine if a triggering event occurred at a known location of a source device. An alarm suppression decision may occur at the detector device and/or relevant information may be sent from the various detectors to a central console for a final alarm decision.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for sharing video streams in a camera system network. The video streams may be modified and/or masked to obscure private video stream features from being shared. An example embodiment operates by linking a first camera system to a first user device. The first camera system detects a second camera system in its field of view, wherein the second camera system is linked to a second user device. Upon exchanging requests to share video streams, the first and second user devices may view the video streams from both camera systems. The video streams may be modified to mask and/or obscure private property and/or known persons to preserve privacy despite sharing video streams. For example, the first camera system may modify and stream a masked video stream to the second user device.
