Definitions

  • the present invention relates to systems for remote optical monitoring, such as closed circuit television (CCTV) systems.
  • CCTV closed circuit television
  • adjustable camera assemblies with remotely and/or automatically controlled motors for panning, (that is, rotating the line of sight of the camera about a vertical axis) tilting (rotating the line of sight about a horizontal axis) and zooming (magnifying or reducing the image).
  • An object of the present invention is to create a flexible surveillance system which provides for the field of view of cameras to be maximised and for the elimination of blind spots.
  • cameras as used herein should be taken to refer to all types of electronic optical surveillance equipment including, for example, charge coupled devices (CCDs).
  • CCDs charge coupled devices
  • the flexibility of the surveillance system is greatly enhanced.
  • cameras are typically wall or ceiling mounted using screws or bolts, so that adjustment of their position typically requires considerable labour in the removal of an existing mounting and the associated wiring, the making good of plaster, and the provision of electrical wiring to the camera's new site and of suitable mounting holes.
  • an optical surveillance system in which a surveillance assembly having at least one electronic optical detector is mounted on an elongate rail so as to be selectively displaceable therealong to a desired location, the surveillance assembly having at least one electrical contact coupled to said detector which is in sliding engagement with an electrical conductor extending longitudinally of the rail for the transference of electrical image signals from the detector to the electrical conductor, wherein the elongate rail comprises a metallic outer section defining an elongate internal space in which the electrical conductor is disposed, the metallic outer section of the rail being adapted to screen the electrical conductor from electromagnetic interference.
  • the camera may simply be moved along the rail, electrical connections being made via the conductor provided at the rail.
  • the elongate rail comprises at least one rail part which is provided, at or adjacent at least one of its ends, with means for mechanical and electrical connection to a further rail part.
  • a modular system of rails is thus made possible, in which a number of straight rail parts may be combined to form a rail of a desired length, or straight and curved rail parts may be joined to create a rail which is shaped, for example, to circumnavigate obstacles or to conform to the perimeter of a room.
  • the said outer section of the rail comprises a longitudinally extending slot which connects with the said internal space and the means for movably mounting the surveillance assembly on the rail comprise a rider adapted to extend through said slot and to engage with an inner surface of the rail.
  • At least one surface of the electrical conductor is exposed along a substantial part of the length of the rail.
  • the contact of the surveillance assembly is thus allowed to make electrical connection with the electrical conductor.
  • the elongate rail is provided with a plurality of electrical conductors which, in use, conduct control signals to the surveillance assembly and/or image signals away from the surveillance assembly.
  • Control and/or image signals may, in accordance with the invention, be multiplexed.
  • the control signals may cause the optical device of the surveillance assembly to pan and/or tilt and/or zoom.
  • the surveillance assembly may, in accordance with the present invention be provided with electrical propulsion means, controllable automatically and/or by signals received via the electrical conductor(s) for propulsion of the surveillance assembly along the rail.
  • the surveillance assembly may comprise a substantially hemispherical dome containing an electronic camera.
  • the rail is labelled 2 while the camera assembly has reference numeral 4.
  • the rail according to the illustrated embodiment of the invention comprises an elongate, hollow, aluminium extrusion which is substantially rectangular in cross section and which serves as a rail outer 5 having two upright walls 6, linked at their upper edges by a horizontal upper wall 8 and meeting, at their lower edges, respective horizontal lower walls 10 which are separated by a longitudinal slot 12.
  • the slot 12 extends the full length of the rail and communicates with an internal space 11 defined by the rail outer 5.
  • a number of elongate conductors extending the full length of the rail, which are insulated from each other and from the rail outer 5.
  • these take the form of three metallic strips 14 embedded in downwardly open slots in an inner plastics extrusion 16.
  • the plastics extrusion 16 is (neglecting the slots) rectangular in cross section, its upper surface lying adjacent the lower surface of the upper wall 8 of the rail outer 5. Lower surfaces of the metallic strips 14 are exposed, permitting electrical contact to be made thereto.
  • the rail outer 5 may serve several functions:-
  • the conductors within the rail are terminated, at one end of the rail, in a screened connector such as a din socket, and are thereby connectable to a monitor, control unit or other electronic device.
  • a "T" shaped rider 20 formed of an insulating material and comprising an upright 22 projecting through the slot 12 and a cross bar 24 which lies within the rail outer 5 and is supported by upper surfaces of the horizontal lower walls 10 to support the camera assembly.
  • Three upwardly open holes are provided in the upper surface of the cross bar 24, each containing a respective electrical contact piece 26.
  • the positioning and spacing of the said holes is such that each of the electrical contact pieces lies directly below a respective metallic strip 14, and electrical contact between each contact piece/metallic strip pair is ensured by two resilient spacers 28 which are compressed between the lower surfaces of the cross piece 24 and the upper surface of the lower wall 10 of the rail outer 5 to upwardly bias the rider 20.
  • Electrical signals from and, in some embodiments of the present invention, to the camera assembly 4 are conducted via wires 29 disposed within the rider 20 to the contact pieces 26, thence to the metallic strips 14, and so ultimately to control electronics/monitors etc.
  • the camera assembly 4 includes, according to the present embodiment, a hemispherical dome 32, which is at least partly transparent, and a planar, disc shaped cover 34 which is rigidly linked to the lower end of the upright 22 of the rider 20.
  • the rider 20 and the cover 34 are integrally formed as a single plastics moulding.
  • the rider 20 is inserted at an open end of the rail 2.
  • the camera 39 itself is attached to a mounting plate 42 which in turn is rotatably joined, along one edge, to the lower wall 38 of the dome 32. Being contained and enclosed within the dome, the camera is protected from physical damage.
  • the camera is manually movable for panning and/or tilting.
  • stepper motors or other electronically controllable actuators may be provided to permit adjustment of the camera by any combination of panning, tilting and zooming.
  • the necessary control signals may be transmitted via the conductors provided at the rail. Where it is necessary to carry control signals and image signals to and from several rail mounted camera assemblies, the number of conductors may be increased and/or the signals may be multiplexed.
  • the camera assembly is provided with means for propulsion along the rail.
  • This may, for example, take the form of a stepper motor which drives a propulsive wheel which, in turn, contacts a surface of the rail outer 5 to drive the camera assembly.
  • the rail mounted camera assembly may take a variety of forms without departing from the scope of the present invention.
  • a small (of the order of 3cm. across) charge coupled device in place of a conventional CCTV camera, there will be provided a small (of the order of 3cm. across) charge coupled device.
  • the means for adjusting viewing angle and the protective dome may be dispensed with.
  • small cameras of this type would be used in conjunction with a rail mounted on a supermarket display or cabinet.
  • the invention could thereby be used to study the dynamics of the shopper population - the number of people passing the display, the number pausing to inspect it, etc.
  • a rail would be mounted along the top of the "back to back" type of supermarket display in which goods are displayed on both long faces of an elongate cabinet.
  • a single camera assembly with a panning facility would thereby be able to survey two supermarket aisles.
  • the rail could be part of a display stand, freezer cabinet etc. This could allow surveillance cameras to be straightforwardly mounted to survey virtually any part of a retail store.
  • the rail is mounted on or integrally formed with components of a suspended ceiling system.
  • a rail may be provided on a downwardly facing surface of the tile spacers used in well known types of ceiling construction.
  • An architect could thus specify that appropriate rails are to be incorporated into a building during installation of the ceiling.
  • the resulting rail system could, if required, form a grid across an entire ceiling, maximising the flexibility of the resulting surveillance system.

Abstract

On décrit un système de surveillance utile, par exemple, pour détecter le vol à l'étalage dans des points de vente au détail, et dans lequel on a monté sur une glissière un ensemble surveillance pourvu d'un détecteur optique (tel qu'une caméra de télévision en circuit fermé), permettant ainsi à ce détecteur d'être placé de manière sélective, par exemple afin de diminuer les angles morts dus à certains obstacles. Cette glissière peut, par exemple, être montée au plafond, ou faire partie d'un meuble, de congélateurs armoires etc.. Les signaux d'image provenant du détecteur optique sont acheminés par au moins un conducteur électrique s'étendant le long de la glissière et ce système peut être conçu pour transmettre des signaux de commande le long de la glissière, à l'ensemble surveillance.
