摘要： The present disclosure describes various embodiments of surveillance systems and methods. In one such embodiment, an exemplary surveillance system includes at least one video camera configured to capture video data of a surveilled area; and a computing device that stores a surveillance program. An exemplary surveillance program includes computer-executable instructions configured to: analyze the video data captured by the at least one video camera; identify objects that enter the surveilled area and log a time at which the objects entered the surveilled area; determine an object type for each object; track the identified objects to determine a period of time the objects have been present within the surveilled area; and generate and transmit an alert for each identified object that has been present within the surveilled area for a period of time that exceeds a predetermined time threshold.

摘要： A method and system for intercepting and forwarding High-Speed SECS Message Services (HSMS) communication between at least two entities, includes a fail-safe bypass to ensure the communications link between the entities is not severed upon failure of the intercepting/forwarding agent. A “pass-through” agent is placed in between two entities communicating via an HSMS link, such that the pass-through agent is able to intercept messages from one entity and forward it to the other entity, and vice versa. The pass-through agent is able to see all messages between the two entities, and is also able to create HSMS messages and send them to one of the entities as if the message had come from the other entity, thereby conferring the ability to inject additional HSMS messages. Should the pass-through agent fail, a bypass mechanism ensures that the two entities can automatically resume HSMS communication without the pass-through agent.

摘要： Embodiments of the present invention relate to managing timestamps associated with received data. According to one embodiment, data is collected from a device that generates data at a specified rate, but which lacks a built-in clock. An accurate timestamp is assigned to the data by first taking an absolute timestamp from a reference clock, and then adding a calculated amount of time to each subsequent data point based on an estimate of the sampling frequency of the device. As the generated timestamp drifts from the actual reference clock time, the sampling frequency is re-estimated based on the amount of detected drift.
