Abstract: A computerized system is configured to detect optical and acoustic events. It is operatively coupled to optical sensor(s) and acoustic sensor(s). It comprises a processing circuitry configured to perform the following: (a) receiving optical data from the optical sensor(s), indicative of optical event(s) associated with an event source(s). (b) receiving acoustic data from the acoustic sensor, indicative of acoustic event(s) associated with the event source. The optical sensor and the acoustic sensor are time-synchronized. (c) identifying the optical and acoustic events, based at least on the optical and acoustic data, (d) determining at least one of: distance and direction of the event source, relative to one or more of the optical sensor and the acoustic sensor. The determination is based at least on the optical event, the acoustic event, the optical data and the acoustic data.
