The Single Location Surveillance Point (SLSP) is a distributed multi-sensor surveillance software system. It contains an arbitrary amount of sensors that collect readings from a single location, which is the surveillance point. The SLSP system contains the following realized sensors: a fingerprint sensor, a video camera, an audio sensor, and a network analyzing monitor. The sensors are located in an indoor region. Each sensor automatically collects information from its environment. Each sensor automatically routes its crude sensor data to a session server, which handles the connections among the components. The session server conveys the crude sensor data to the logical decision making service. The logical decision making server (LDMS) automatically derives the situation at the surveillance point based on the received sensor data. The intention is to deduct the situation which is transpiring in the surveyed area based on the received crude data from the sensors. By deriving the situation of a surveyed area, the surveillance personnel may utilize refined information cogent to occurring events of the surveyed area. This branch of the SLSP intends to facilitate the collection of data from a surveillance point and decrement the amount of superfluous information and rendered to the surveillance personnel, by acquiring automatically sensor data and providing automatically derived information to the surveillance personnel’s end-device. The operability of the constructed prototype indicates that this endeavor is attained. The research is based on the constructive method of the related publications and technologies and the results are derived by the implemented branch of the SLSP system.
