An automated intelligent surveillance system comprises one or more fixed reference cameras to spatially map and observe a panoramic field of view, together with a movable narrow-field high resolution camera which is controlled in pan tilt & zoom, and a computing device. The computing device is capable of analysing the reference images received from anywhere within the panoramic field of view, and identifying the presence of specific types of object or specific behaviours of objects. The computing device uses the outcome of this analysis to direct the movable camera to the appropriate area of the spatial map to cause it to zoom in to gather close-up images of one or more of the selected objects or events of interest. These images are recorded synchronously with the related wide angle reference images, in a high speed random access store within the computing device. The parameters defining an object or event as being of interest may be pre-set, user selected, or adaptively learned by the computing device.
