`
`SURVEILLANCE APPARATUS, SYSTEM AND METHOD
`
`The present invention relates to surveillance apparatus, systems and
`
`methods, and more particularly to closed circuit television (CCTV) security
`
`systems and apparatus which utilise cameras mounted on masts.
`
`With conventional methods of CCTVinstallation, for example when
`
`installing CCTV cameras mounted on masts in car parks or other open
`
`outdoor sites, there is a requirement to dig up tracts of land to facilitate the
`
`laying of electrical power cables, and CCTV cables required to transmit the
`
`video data to a remote control centre, and to transmit control signals from
`
`the control centre to enable an operator to adjust the aim and the lens
`
`10
`
`This installation process is extremely
`system of the individual cameras.
`disruptive to the public,
`time consuming and expensive.
`It
`is also a major
`obstacle to the expansion of CCTV security systems in the prevention of
`
`crime.
`
`In addition, each camera is usually mounted in an exposed position at
`
`the top of a specially designed mast, so that its presence is obvious to the
`
`15
`
`public.
`
`It
`
`is an object of the present
`
`invention to alleviate or effectively
`
`overcome one or more of these disadvantages, and to enable installation and
`
`use to be simplified and to be more cost effective.
`
`The apparatus embodying the invention basically comprises a self-
`contained surveillance unit or module incorporating a plurality of CCTV
`
`20
`
`cameras mounted in a housing adapted to be attached to the top of a
`
`conventional or commercially available post or pole of a lamp post or other
`
`piece of street furniture or the like.
`
`The cameras are adapted to beinitially
`
`adjusted and set, for example manually by an installation engineer, so that
`
`25
`
`each camera will be aimed at a particular predetermined target zone or area
`
`and will have a particular predetermined field of view. The unit is preferably

`
`designed to resemble a lamp unit which would normally be installed on a
`
`lamp post or the like.
`
`Systems embodying the invention, and the apparatus or pole-mounted
`
`surveillance units which comprise components of
`
`the system, may be
`
`5
`
`arranged and adapted to operatein at least six different configurations. The
`
`following provides an overview of some of
`
`the configuration options
`
`available.
`
`The system may be designed to allow for either
`
`local or central
`
`storage of video surveillance data.
`
`10
`
`The system may also be designed to allow for the use of wireless
`
`transmission in the case of a centralised storage system, and the use of solar
`
`power supply or back-up modules where the provision of a mains power
`
`supply is impracticable.

`“Lamp Post CCTV" Unit Mark | (Local Storage) Stand Alone
`The Mark | configuration consists of a stand alone lamp post CCTV
`system comprising a surveillance unit including a housing or head in the form
`
`of a pod or dome, attached to the top of the tubular post or pole of a
`
`AXIS EXHIBIT 1008-3

`
`lamp
`in place of the usual
`conventional commercially available lamp post
`unit. The housing or head contains up to eight CCTV cameras, for example
`
`four angularly displaced cameras, arranged in what
`
`is
`
`referred to for
`
`convenience as a “north, south, east, west” array. The data output from the
`
`cameras is recorded locally by a digital video recorder or archive (DVA). The
`
`DVA is mounted within the lamp post, or within the housing or head of the
`
`unit. Access to the DVAis performed by an operator connecting an operator
`
`view module, a standard PC, or similar device, to output terminals provided
`
`at the base of the lamp post.
`
`10
`
`The Mark | unit has power supplied from an external source (e.g. a
`
`mains power supply or a battery pack located in the base of the lamp post).
`
`“Lamp Post CCTV” Unit Mark Il
`
`(Local Storage) Stand Alone
`
`The MarkIt configuration differs from the Mark | configuration in that
`
`the unit requires no external power supply. The unit is powered by a solar
`
`15
`
`power system consisting of a solar panel (fitted to the domed housing or
`
`head of the unit) and a series of deep cycle batteries, which are recharged
`
`by, or supplement the solar power system, installed within the base of the
`
`lamp post, or in the housing or head.
`
`“Lamp Post CCTV” Unit MarkIll (Central Storage) Stand Alone
`
`20
`
`The Mark Ill configuration differs from the Mark | and li configurations
`
`in that
`
`the unit does not
`
`incorporate its own DVA.
`
`Instead,
`
`the video
`
`outputs from the cameras are physically connected to a central point (control
`
`room) by electrical or optical cables, where the signals are recorded by a
`
`centralised DVA.
`
`25
`
`“Lamp Post CCTV” Unit Mark IV (Central Storage) Stand Alone
`
`The Mark IV configuration differs from the Mark Ill configuration in
`
`that, like the MarkII unit, it incorporates its own internal power supply.

`
`“Lamp Post CCTV” Unit Mark V (Central Storage) Stand Alone
`
`The Mark V configuration differs from the Mark | configuration in that
`
`the video output from the cameras is transmitted to a central point (control
`
`room) by a wireless transmission system operating, for example, within the
`
`2.3-2.4 or 2.4 to 2.5Ghz frequency range. This video transmission system
`
`consists of a wireless video transmission interface and a yagi directional
`
`transmission antenna within the local unit, and a wireless video receiver
`
`interface and a yagi directional receive antenna at the central point.
`
`The
`
`video output from the cameras may be multiplexed at the lamp post and de-
`
`10
`
`multiplexed at the central recording point where the signals are recorded by a
`
`centralised DVA.
`
`“Lamp Post CCTV” Unit Mark VI (Central Storage) Stand Alone
`
`The Mark VI configuration differs from the Mark V configuration in
`
`that, like the Mark Il unit, it incorporates its own internal power supply.

`
`Overview of significant features
`
`The lamp post-or pole-mounted local surveillance unit embodying the
`
`invention may provide up to eight,
`
`for example four, covert surveillance
`
`camerasinstalled in the housing or head mounted on top of the lamp post in
`
`20
`
`place of the usual lamp unit. Video signals from these cameras are recorded
`by a digital video recorder or archive that is also contained within the lamp
`post, or housing or head.
`
`At the same time that the video signals output from the cameras are
`
`recorded bythe internal or local digital video recorder, or instead of using or
`
`fitting an internal or
`
`local
`
`recorder,
`
`up to eight video signals can be
`
`25
`
`transmitted (in the 2.4-2.5 or 2.3 to 2.4Ghz range) for (optional) recording
`
`by a remote digital video recorderor archive at a central point (control room),
`
`or in another lamp post. The transmission unit for each surveillance camera

`
`PCT/GB2004/001655
`
`5
`
`consists of a video transmission module (with up to eight channel settings)
`and a unidirectional antenna.
`
`The pole-mounted unit is powered by a bespoke solar power system.
`This system consists of a solar panel or array that is fitted to the exterior of
`
`the unit’s cover, for example domed cover, a solar charge voltage regulator
`and one or more batteries such as batteries of the type known as dryfit
`deep cycle batteries.
`
`The solar voltage regulator and deep cycle battery are contained within
`
`the housing or head of the unit, or within the base of the lamp post,
`
`and
`
`10
`
`provide,
`
`in one specific example,
`
`a 12VDC power supply to the cameras,
`
`digital video recorder and wireless video transmitters contained within the
`
`housing or head
`
`Condensation build-up within the housing is minimised or effectively
`prevented by the inclusion of one or more,
`for example four, silica gel
`modules or troughs that remove moisture from the atmosphere within the
`
`housing.
`
`Video data from the digital video recorder can be downloaded from the
`
`unit by the connection of an operator view module. This module provides a
`10 Base T connection to the base of the lamp post for the downloading and
`subsequentreplay of historical video information.

`
`Surveillance Cameras Overview
`
`The surveillance cameras of each pole-mounted unit provide live video
`output data to the rest of the system for recording orlive viewing by system
`operators. The cameras used by the units may utilize CCD (charge couple
`device)
`technology. Two types of camera may be incorporated in units
`supported by the system. Colour cameras are incorporated for use during

`
`daytimeorin illuminated areas, and a black and white “night vision” cameras
`
`are incorporated for areas that have no lighting during night
`
`time. Both
`
`camera types support PAL or NTSC standards. The “night vision” camera,
`
`to be effective, requires that the target area is lit by infrared light. An
`
`individual unit will usually incorporate only one type of camera depending
`
`upon its intended location and purpose, but both types, for example two
`
`sets,
`
`could
`
`be
`
`incorporated in
`
`a
`
`single unit
`
`if
`
`appropriate to the
`
`circumstances.
`
`1.1
`
`Camera Lens
`
`Three distinct zones may be implemented using cameras with different
`
`lens sizes or characteristics. These zones are termed Detection, Recognition
`
`and Identification zones.
`O Detection cameras will provide a wide view of the area thus
`
`allowing the general detection of personnel and events.
`
`15
`
`Recognition cameras will provide a greater depth of view for the
`O
`viewing of a protected area.
`|
`O
`identification cameras will be placed or directed at entry points,
`
`exit points, panic zones and other areas of
`
`importance to allow for the
`
`capture of close-up images to facilitate the clear
`
`imaging of
`
`identifying
`
`20
`
`features.
`
`2.0 Wireless Video Signal Transmission
`
`In this embodiment, the lamp post unit provides a local wireless link
`
`between the surveillance cameras and an optional remote or central digital
`
`video recorder. The wireless link consists of a transmitter module that is
`
`25
`
`preferably integrated into each surveillance camera, and a_
`
`central receiver
`
`unit that collects the signal and provides it as an analogue output to the
`
`remote digital video recorder.

`
`PCT/GB2004/001655
`
`3.0 Digital Video Recorder
`
`The digital video recorder or archive unit takes the video output from
`
`the surveillance cameras (by direct connection within the lamp post, and/or
`
`via the wireless connection) and records these images or image data on to
`
`digital media (e.g. hard disk drives). The digital video recorder provides
`
`unattended recording, remote administration and remote viewing of live or
`
`historical video data (via the operator view module).
`
`Each digital video recorder captures video signals from up to eight
`
`surveillance cameras. The video signals are recorded at a resolution of up to
`
`10
`
`800 by 600 pixels.
`
`The amountof disc space per unit is configurable up to 5 terra byte.
`
`Each frame of data received by the digital video recorderis digitally
`
`watermarked with the date, time and camera location.
`
`4.0 Operator View Module
`
`The operator view module allows system operators to playback the
`
`system’s video recordings, or view live video. The module is connected using
`
`a connection provide at the base of the lamp post, or directly in the case of a
`
`remote digital video recorder.
`
`5.0
`
`Solar Power Module
`
`20
`
`The solar power module provides the power requirements for all the
`
`components contained within the lamp post unit. The module consists of
`
`three parts:
`
`[1 Deep cycle battery
`
`OO
`
`Solar charge regulator
`
`25
`
`Solar cell panel or array
`
`5.1 Deep cycle battery
`

`AXIS EXHIBIT 1008-8
`
`

`

`WO 2004/095386
`
`PCT/GB2004/001655
`
`8
`
`The battery used is a deep cycle rechargeable unit, for example known
`
`as a dryfit battery, especially designed for solar power applications. The
`
`battery will allow the continued operation of the surveillance camera, digital
`
`video recorder and wireless video transmission system during night time and
`
`periods of low light.
`
`5.2
`
`Solar Charge Regulator
`
`Due to the nature of solar power, voltage output can vary quite
`
`significantly due to fluctuations in weather conditions. In the event that the
`
`panel is producing a voltage in excess of a predetermined value, 13.8 VDCin
`
`a specific example,
`
`for a prolonged period of time,
`
`this would result
`
`in
`
`damage to the batter cells, causing failure or reducing the battery lifetime.
`The solar charge regulator, for example of the type knownasa solar guard,
`is especially designed to ensure that the output from the solar panel does not
`
`exceed 13.8 VDC while charging the batteries, thus prolonging thelife of the
`
`system and effectively preventing battery and equipment damage due to
`
`over-voltages.
`
`5.3
`
`Solar Cell Panel or Array
`
`The solar paneis to be supplied are preferably of the polycrystalline
`
`silicon type, which are suitable for medium to high power applications. The
`
`20
`
`purpose of the solar panel is to provide a sufficient charge to the batteries in
`
`order to keep the system operating on a 24 hour basis.
`
`The preferred embodiments of the invention provide a free-standing
`
`modified lamp post (without the lamp unit/lighting apparatus) which is a
`
`complete CCTV security management system. The product can be erected
`
`25
`
`anywhere. on footpaths,
`
`in
`
`town centres, within car parks,
`
`schools,
`
`hospitals, shopping centres on railways,
`
`in sea/air ports, and in or around
`
`commercial or
`
`industrial
`
`installations or sites.
`
`It
`
`is a completely self-

`
`from the
`contained security system. CCTV systems currently suffer
`disadvantage that, whenasystem isto be installed, there are always ground
`civil engineering works and external and internal building attachment works
`to be carried out,
`involving laying the electrical power cables and camera
`video and control cables to the various points.
`The preferred embodiments of the invention enable the laying of the
`cables, etc.
`to be dispensed with,
`thereby creating a much moreflexible
`recording and transmission system that,
`if required, can also interact with
`existing CCTV technology. Accordingly,
`these embodiments provide a
`dome/pod surveillance unit at the top of a modified lamp post, which is a
`complete self-contained, solar powered, digital video recording management
`security system.
`
`15
`
`20
`
`25
`
`By way of one specific example, a particular application of a system
`embodying the invention is a hospital car park that requires 24 hour CCTV
`security monitoring. Hospitals inevitably have several car parksi.e., patients,
`out patients, visitors and staff.
`
`The various car parks within the hospital grounds would need to be
`surveyed. Position points for each lamp post would be established and
`
`mapped and eachprospective lens size selected that would be suitable for
`each view from each camera (taking into account the depth and angle of
`field of view)
`to achieve detection,
`recognition and identification. Each
`
`camera would be connected to an antenna that would be tuned to transmit
`camera image data to a receiving antenna associated, for example, with a
`de-multiplexing. console at a central recording point within a building, whilst
`at the same time recording the data in the digital video recorder within the
`lamp post
`(or the lamp post-mounted unit),
`to cover for monitoring staff
`whennotavailable at the central recording point.

`and 8). A CCTV camera 13 is located in each chamber sector, mounted
`
`from the camera support ring 12 by a hinged bracket arrangement 14 (see
`
`also Figs. 9 and 10).
`
`The cameras are manually adjustable in azimuth by
`
`sliding the bracket arrangements 14 around the ring 12 and clamping them
`
`in the required positions, for example 90° apart as shown in Fig. 3.
`
`The
`
`cameras are adjusted in elevation by means of the hinges, and are tightened
`
`and locked at
`
`the required inclinations by locking nuts or
`
`the like,
`
`for
`
`example as shown in Fig. 2.
`
`These adjustments are carried out after
`
`10
`
`installation of the pole 1 and associated surveillance unit 2.
`
`As will be apparent
`
`from Fig. 2,
`
`the transparent plastic camera
`
`chamber cover 3 is curved and dimensioned so that,
`
`irrespective of the
`
`vertical or horizontally adjustment of the optical axis or field of view of each
`
`camera, the front face or lens of the camera will be close to and effectively
`
`15
`
`perpendicular to the surface of the cover. This possesses the advantage that
`
`spurious reflections, etc. are reduced or effectively eliminated.
`
`The lower and upper covers 3 and 4 are provided with peripheral rims
`
`which are bolted to the platform 7 with the interposition of resilient sealing
`
`rings. The lower cover 3 also has a lower axial opening through which the
`
`20
`
`stub tube 10 passes, and around the opening, the lower cover 3 is bolted
`
`upwardly to the underside of
`
`the intermediate flange 10a which the
`
`interposition of a resilient sealing ring. The upper and lower chambers are
`
`therefore hermetically sealed against ingress of rain, etc. To minimise or
`
`effectively eliminate internal condensation, the camera chamberincorporates
`
`25
`
`a trough 3c (Fig. 2)
`
`for a dessicant such as silica gel. Additionally or
`
`alternatively, one or other chamber may contain one or more electric cooling
`
`fans, controlled by a temperature gauge or sensor, for circulating air around

`
`the two chambers, via ventilation openings in the platform 7, and,
`
`if
`
`necessary in the dividing partitions or fins in one or both chambers.
`
`With reference to Figs. 2 and 4, the upper chamber4ais provided with

`The walls

`fins or partitions which divide the upper chamber into
`
`sectors corresponding to those of the lower chamber. The walls 4c define a
`
`central rectangular area which, in some embodiments, accommodatea digital
`
`video (DVD) recorder 8. The upper chamber also contains, mounted on the
`
`platform 7, multi- or unidirectional antennae 15 connected one to each
`
`transmitter incorporated in each camera, and an array of deep cycle batteries
`
`16.
`
`Preferably,
`
`there are two batteries
`
`for powering each camera,
`
`electrically interconnected via appropriate circuitry so that if the output of
`
`the battery powering a particular camera falls below an acceptable level, the
`
`associated second or stand-by battery will take over or act as a back-up.

`When sufficient
`power supplied by the batteries may be replaced or augmented by power
`
`supplied by the solar cell panel or array 5 mounted on top of the upper
`
`domed cover 4 (see Fig. 5). The solar panel is connected to the batteries
`
`and/or cameras via appropriate circuitry including protective and/or voltage
`
`20
`
`control circuitry or modules 18, for example known as solar guards, one for
`
`each camera, mounted on the underside of the plate 9 as shownin Fig. 6.
`
`These modules prevent the batteries and/or cameras from being subjected to
`
`excessively high voltages from the solar panel, for example when the panel
`
`is subjected to’intense sunlight.

`
`It will be appreciated that basic CCTV surveillance unit 2 of the type
`
`described and illustrated may be readily adapted and utilised in any of the
`
`configurations or “Marks” described earlier.

`
`The CCTV surveillance units and systems or networks embodying
`them possess numerous advantages.
`The units are self-contained and may be simply assembledto, example
`fitted into,
`the top of conventional commercially available lamp posts or
`posts or poles of other commercially available street furniture with the
`minimum of modification. This allows the installer to use readily available
`poles of conventional design to suit
`the particular application with the
`minimum of modification, obtained for example from a local supplier instead
`of from the supplier of the surveillance units.
`
`10
`
`15
`
`20
`
`25
`
`The surveillance units have the capability of being totally self-
`contained, i.e. may incorporate their own source of power(batteries and/or
`solar panels) and associated control circuitry, one or more radio transmitters
`and associated aerials for transmitting the video data from the individual
`
`cameras, and/or from a local internal video recorder, to a remote receiver at
`a central point. Therefore,
`the disruptive time consuming and expensive
`ground civil engineering work required to install a conventional CCTV
`security system is effectively eliminated or substantially alleviated.
`Since the cameras are adjusted and fixed in set positions to provide
`the required surveillance coverage,
`in combination with the adjusted and
`fixed cameras of other similar surveillance units at a particular site (e.g. car
`park, etc),
`the additional expense and complication of providing remotely
`controlled cameras and associated cabling, and providing staff at the central
`point or control station for remotely manipulating the cameras, is eliminated.
`The lamp post-mounted surveillance units are particularly suitable for
`covert surveillance since,
`to casual or uninformed observers or passers by,
`they resemble the lamp units of conventional lamp posts.
`It will be understood that various modifications may be made without

`
`departing from the scope of the present invention .
`
`For example video recorders, cameras, solar cells and/or batteries of
`
`various types and configurations other than those specifically described and
`
`illustrated herein may be employed, and the components may be disposedat
`
`other locations in and/or on the surveillance unit or pole. For example, if the
`
`video recorder is not
`
`located in the associated component
`
`in the upper
`
`chamber, the batteries may be relocated there instead.
`
`The central control point or station,
`
`instead of being located in a
`
`building, may comprise one or more of the posts-mounted surveillance units
`
`as described and/or
`
`illustrated.
`
`For example, a number of such post-
`
`mounted slave or local surveillance units may be arranged to transmit video
`
`data from their cameras to a common recorder in a central or master post-
`mounted surveillance unit.
`If desired, the array of post-mounted surveillance
`
`units at a particular site may include a number of slave and masterunits.
`
`15
`
`The various permutations and combinations herein described and/or
`
`illustrated, all of which may be incorporated in a basic surveillance unit,
`
`render the apparatus and systems embodying the invention particularly
`
`versatile and adaptable.
`
`Whena local post-mounted unit or post incorporates a video recorder,
`
`20
`
`the recorder data may be transmitted to the central point or control room,
`
`etc. by a single transmitter instead of by individual transmitters associated
`
`with each camera, so that the latter transmitters and their aerials may be
`
`omitted.
