A surveillance system comprises an autonomous vehicle or pod provided with one or more sensors suitable to acquire data representative of a monitored area, said sensors being coupled with comparison means capable of comparing data acquired by said one or more sensors at the same location and at different times and to generate a signal indicative of a change in said data when two or more consecutive data sets are such that a difference can be determined. Optional active response means are provided, which are suitable to respond to a threat. |
