Abstract: A video surveillance system is disclosed. The system includes: at least one camera to observe a surveillance field and provide resulting video data; at least one beacon comprising at least one light emitting element and a controller providing an actuation sequence to the light emitting element such that it emits a binary signal comprising sequential on/off flashes; and a video analytics system comprising a processor configured to receive video data captured by the, at least one camera and analyse the video for the presence of light emissions from a beacon. The binary signal may consist of a plurality of transmission packets, each repeating an encoded set of data. Each transmission packet may comprise a plurality of functional sub packets, for example, a first sub-packet comprising a fixed code and a second sub-packet which changes between transmission packets.

Abstract: An exposure monitoring system is disclosed. The system comprises: at least one camera to observe a monitoring area; a plurality of beacons each comprising at least one light emitting element and a controller to provide an actuation sequence to the light emitting element; and a video analytics system. The video analytics system comprises a processor configured to receive video data captured by the at least one camera, analyse the video for the presence of light emissions from the beacons, decode the actuation sequence of the light emissions from any detected beacon to provide an identification for the beacon, compile a location history for each beacon, over time, detected within the surveillance area, and determine an exposure risk associated with each beacon. A method of exposure monitoring is also disclosed.

Abstract: A stereo camera, including an imaging sensor, and an optical apparatus comprising first and second apertures separated by an interocular distance and configured to focus first and second images on the imaging sensor in a side by side arrangement. An imaging system including the stereo camera, and at least one image processor, configured to receive first and second frames of image data from a stereo camera, and construct volumetric image data based on binocular disparity between the first and second frames.
