`AXIS EXHIBIT 1020-4
`
`

`

`[0001] The present invention concerns a monitoring device arrangement comprising
`a mounting rail and at least two fixed monitoring devices mounted5 on holders
`arranged on said mounting rail.
`Background
`
`BACKGROUND
`
`[0002] Monitoring device arrangements may include a number of monitoring devices,
`such as cameras and IR detectors. The monitoring devices may be1 0 mounted on a
`support and may be used for monitoring an area around the monitoring device
`arrangement. The monitoring devices in such a monitoring device arrangement may
`all be of the same type, or they may be of different types. For instance, one
`monitoring device may be a fish-eye camera and another monitoring device may be a
`fix focus lens camera.
`
`15[0003] It may be desirable to monitor, e.g., a 360°360.degree. field of view around
`the monitoring device arrangement. However, in some locations, there may be objects,
`such as walls, blocking the view of one or more of the monitoring devices, reducing
`the usable field of view of the monitoring device arrangement. Further, the most
`important parts of the scene to monitor may be located such20 that they are near the
`edge of the field of view of one of the monitoring devices, whereas it would be
`desirable to have these parts at the centre of the field of view. It would therefore be
`desirable to have a monitoring device arrangement allowing flexibility in the
`positioning of the monitoring devices.
`25 Summary of the invention
`
`[0004] WO 2004/095386 discloses a surveillance apparatus incorporating a plurality
`of CCTV cameras individually adjusted and fixed to survey the required areas of a
`site. The cameras are mounted from a camera support ring by a hinged bracket
`arrangement. The cameras are manually adjustable in azimuth by sliding the
`bracket arrangements around the support ring and clamping them in the required
`positions.
`
`SUMMARY
`
`[0005] It is an object of the present invention to provide a monitoring device
`arrangement which alleviates the problems associated with prior art monitoring
`device arrangements.
`
`[0006] A particular object is to provide a monitoring device arrangement which30
`enables flexible, yet well-defined positioning of monitoring devices.
`2
`
`
`
`
`1
`
`AXIS EXHIBIT 1020-5
`
`

`

`[0007] According to the invention, these and other objects are achieved, in full or at
`least in part, by a monitoring device arrangement comprising a mounting rail, and at
`least two fixed monitoring devices, said fixed monitoring devices each being mounted
`on a respective holder, said holders being arranged on5 said mounting rail, wherein
`each said holder comprises a lock device locking said holder in a determined position
`on said mounting rail, and wherein said lock device is releasable to allow sliding
`repositioning of said holder on said mounting rail. It may be noted that the term
`"fixed monitoring device" refers to a monitoring device which is not in itself capable of
`panning or tilting, but10 which may be capable of zooming. With a monitoring device
`arrangement according to the invention, it is possible to mount fixed monitoring
`devices on the mounting rail with a possibility of adjusting the positions of the fixed
`monitoring device by sliding them along the mounting rail with the lock device
`released. Once the fixed monitoring devices have been placed in the desired15
`position, the lock device of the holder may be locked, and the fixed monitoring devices
`may be securely held on the mounting rail. In this manner, the monitoring device
`arrangement is flexible in that the positions of the fixed monitoring devices in
`relation to each other or in relation to objects in the surroundings may be chosen in
`accordance with current needs. Thus, for instance,20 fixed monitoring devices may
`be positioned to cover a desired field of view and avoiding positions where the field of
`view of one or more of the fixed monitoring devices would be blocked by a wall or
`other object. Further, parts of a potential field of view which for other reasons should
`not be monitored may also be avoided. This may, e.g., be the case if a monitoring
`device ar-25 rangementarrangement is placed indoors, and it is not allowable to
`monitor persons outside, through a window. By adjusting the positions of the fixed
`monitoring devices on the mounting rail, their usable combined field of view may
`thus be utilised, instead of having to shut off an inappropriately directed fixed
`monitoring device. Conversely, there may be particularly important parts of the
`scene30 to monitor, and by adjusting the positions of the fixed monitoring devices on
`the mounting rail, the field of view may be centred on the most important parts of the
`scene.
`3
`
`[0008] In some embodiments, the mounting rail is arcuate or angled. Thereby, a wide
`range of positions for the fixed monitoring devices are available in order to cover a
`desired field of view. If the mounting rail is arcuate and is free from sharp angles, the
`holders may easily be slidingly repositioned along the5 entire arc portion.
`
`[0009] The mounting rail may be circular. In this manner, the fixed monitoring
`devices may be positioned in a large number of positions along the circular mounting
`rail, thereby allowing a large combined field of view.
`
`[0010] In an embodiment, the lock device of the holder comprises a magnet,1 0 and
`the mounting rail comprises ferromagnetic material. This is a practical way of
`
`
`
`2
`
`AXIS EXHIBIT 1020-6
`
`

`

`achieving a releasable lock, which does not require tools for releasing and locking the
`holder.
`
`[0011] The mounting rail may comprise at least one magnet, and said holder may
`comprise ferromagnetic material. This is also a practical way of achiev-15
`ingachieving a releasable lock, which does not require tools for releasing and locking
`the holder.
`
`[0012] In one embodiment, the holder comprises a biasing member biasing said
`holder against said mounting rail. In this manner, it may be ensured that the holder
`is securely held in position on the mounting rail.
`
`20[0013] The biasing member may comprise a leaf spring.
`
`[0014] The mounting rail may have at least one recess or protrusion in a
`predetermined position along said mounting rail, and the biasing member may be
`adapted to engage said recess or protrusion for locking said holder in said
`predetermined position. This makes it easy for a person installing the monitor-25
`ingmonitoring device arrangement to place the fixed monitoring devices correctly in
`case one of the predetermined positions is desired. Similarly, this may assist in
`adjusting the position of the fixed monitoring devices in an already mounted
`monitoring device arrangement. For instance, the mounting rail may be provided
`with four recesses or protrusions in positions goo90.degree. apart along the30
`mounting rail. This may simplify equidistant positioning of four fixed monitoring
`devices for a 360°360.degree. field of view.
`
`[0015] The holder may comprise a rotation prevention member preventing said
`holder from rotating around said mounting rail. This may ensure a stable
`4 positioning of the fixed monitoring device once the holder is locked in the desired
`position.
`
`[0016] In one embodiment, the holder comprises a retaining member arranged to
`retain said holder on said mounting rail also when said lock device5 is released.
`Hereby, it may be ensured that the holder is retained on the rail even during a
`repositioning movement. It may also be ensured that the holder is retained on the
`mounting rail even if the locking function of the lock device were to fail for some
`reason.
`
`[0017] The retaining member may comprise a hook retaining said holder on1 0 said
`mounting rail. This is a practical way of ensuring that the holder is kept on the
`mounting rail.
`
`
`
`
`3
`
`AXIS EXHIBIT 1020-7
`
`

`

`[0018] At least one of said fixed monitoring devices may be a fix focus lens camera.
`Further, at least one of said fixed monitoring devices may be a
`nonpannable,non-pannable, non-tiltable camera capable of zooming.
`
`15[0019] In an embodiment, the monitoring device arrangement further comprises a
`pannable and/or tiltable monitoring device, wherein the mounting rail is arranged
`surrounding said pannable and/or tiltable monitoring device. For instance, the fixed
`monitoring devices may be used for getting an overview and the pannable and/or
`tiltable monitoring device may be used for targeting20 objects found using the
`overview monitoring devices.
`
`[0020] The monitoring device arrangement may further comprise a shielding portion
`arranged to shield said pannable and/or tiltable monitoring device from
`environmental factors, such as sunlight or rain. In this manner, the pannable and/or
`tiltable monitoring device may be protected from harmful envi-25
`ronmentalenvironmental factors, such as ingress of rain. If the pannable and/or
`tiltable monitoring device is a camera, it may be advantageous to shield it from the
`sun in order to obtain good images.
`
`[0021] The pannable and/or tiltable monitoring device may be a PTZ camera, i.e. a
`camera capable of panning, tilting and zooming. If the fixed monitoring30 devices are
`cameras, these may be used for getting an overview image of an area surrounding the
`monitoring device arrangement. The PTZ camera may be used for tracking and
`zooming in on objects found in the overview image. The overview image may be
`stitched together from the images captured by
`5 the respective fixed cameras to form a panoramic image. The overview may also be
`shown as separate images, e.g., on a video wall.
`
`[0022] The monitoring device arrangement may comprise a motor for sliding
`repositioning of said holder on said mounting rail. In this manner, the posi-5
`tionspositions of the fixed monitoring devices may be adjusted even if the monitoring
`device is difficult to reach, or if adjustment is needed also after installation of the
`monitoring device, e.g., for different monitoring needs during the day and at night. A
`further scope of applicability of the present invention will become apparent from the
`detailed description given below. However, it should be10 understood that the
`detailed description and specific examples, while indicating preferred embodiments
`of the invention, are given by way of illustration only, since various changes and
`modifications within the scope of the invention will become apparent to those skilled
`in the art from this detailed description.
`
`15[0023] Hence, it is to be understood that this invention is not limited to the
`particular component parts of the device described or steps of the methods described
`as such device and method may vary. It is also to be understood that the terminology
`used herein is for purpose of describing particular embodiments only, and is not

`15 Detailed description of embodiments
`
`DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
`
`
`
`5
`
`AXIS EXHIBIT 1020-9
`
`

`

`
`[0034] In FigFIG. 1 a monitoring device arrangement 1 is shown comprising a
`number of monitoring devices 2. In this embodiment, the arrangement is a camera
`arrangement comprising a number of fixed cameras, i.e. cameras that are in
`themselves incapable of panning and tilting. The camera arrangement20 1 has a
`shielding portion 3 for shielding the fixed cameras 2 against environmental factors,
`such as sunlight, rain, and snow. Further, the camera arrangement 1 has an
`attachment portion 4 for attaching the camera arrangement to, e.g., a mounting
`bracket (not shown in FigFIG. 1) for mounting on a surface such as a wall, a ceiling,
`or a pole. The fixed cameras 2 are arranged25 inside a protective window 5. At an end,
`which in FigFIG. 1 is a lower end, of the camera arrangement, there is an opening 6
`surrounded by a trim ring 7. The shielding portion 3 may be made of aluminium,
`making it allowable to arrange the camera arrangement recessed in a ceiling while
`fulfilling fire safety requirements.
`
`30[0035] Turning to FigFIG. 2, a fixed camera 2 of the camera arrangement 1 may be
`seen. The fixed camera 2 is arranged in a holder 8, which is mounted on a mounting
`rail 9. In the embodiment shown, the mounting rail 9 is of circular shape, such that it
`surrounds the opening 6.
`7
`
`[0036] As may be more clearly seen in FigFIG. 3, the holder 8 has a number of
`retaining members in the form of hooks 1 010 and bosses 11. The hooks 10 are
`arranged at the front of the holder 8, such that when the holder 8 is mounted on the
`mounting rail 9, the hooks 10 are engaged around a radially outer rim5 12 of the
`mounting rail 9 (see FigsFIGS. 2 and 4). The bosses 11 are arranged at the back of
`the holder 8, such that when the holder 8 is mounted on the mounting rail 9, the
`bosses 11 abut a radially inner rim 13 of the mounting rail 9, thereby preventing the
`holder 8 from tilting or rotating forwards. Further, the holder 8 has a biasing
`member in the form of a leaf spring 14 arranged at the10 back of the holder 8. The
`leaf spring 14 is slightly hook-shaped. When the holder 8 is mounted on the mounting
`rail 9, the leaf spring 14 urges the holder 8 radially outwardly against the inner rim
`13 of the mounting rail 9 and the hook-shape engages the inner rim 13.
`
`[0037] With reference to the cross-section shown in FigFIG. 4, the holder 8 has a15
`locking device in the form of a magnet 15. In this embodiment, the mounting rail 9 is
`made of a ferromagnetic material, and the magnet may therefore securely lock the
`holder 8 in position on the mounting rail. By slightly lifting the holder 8 off the
`mounting rail 9, or by pressing back the leaf spring 14 and tilting the holder 8
`slightly forward, the magnetic force of the magnet 15 may20 be overcome, such that
`the holder can be moved slidingly along the mounting rail 9 to a desired position. The
`hooks 10, bosses 11, and leaf spring 14 ensure that the holder is retained on the
`mounting rail 9 during this movement. Once the holder 8 has been moved to the
`desired position, the holder is released, such that the force of the magnet 15 locks the
`
`
`
`6
`
`AXIS EXHIBIT 1020-10
`
`

`

`holder 8 in place. Thus,25 the holder 8 may be unlocked, moved, and locked without
`the need for tools.
`
`[0038] As may be seen in FigFIG. 2, recesses or notches 16 are formed in the
`mounting rail 9 at predetermined positions. The holder 8 has a protrusion in the form
`of the leaf spring 14, which may engage the notch 16 when the holder is positioned in
`one of the predetermined positions. When a holder 8 is30 moved to one of the
`predetermined positions, the leaf spring 14 of the holder snaps into the
`corresponding notch 16. This snapping action of the leaf spring may be heard and/or
`felt by the person moving the holder 8, indicating that the fixed camera 2 and the
`holder 8 have reached the predetermined position.
`8 For instance, the mounting rail g9 may have four notches 16 spaced goo90.degree.
`apart, thereby simplifying mounting of four fixed cameras 2 at right angles for
`creating a combined 360°360.degree. view.
`
`[0039] Now turning to FigFIG. 5, the camera arrangement 1 may be used as an5
`accessory for a pannable and/or tiltable camera 17. In such case, the pannable and/or
`tiltable camera 17 may be mounted inside the camera arrangement 1 with a dome 18
`of the pannable and/or tiltable camera 17 protruding through the opening 6 of the
`camera arrangement 1. The combination of the camera arrangement 1 and the
`pannable and/or tiltable camera 18 may be10 mounted to, e.g., a wall using a
`mounting bracket 1g,19, which may be attached via the attachment portion 4 of the
`camera arrangement 1. When the accessory 1 and the pannable and/or tiltable
`camera 17 are assembled to a combined camera arrangement 101, the shielding
`portion 3 may shield the pannable and/or tiltable camera 17 from sun, rain, snow,
`and other potentially15 harmful environmental factors.
`
`[0040] The fixed cameras 2 may be fix focus lens cameras, and the pannable and/or
`tiltable camera 17 may be a PTZ camera, i.e. a camera capable of panning, tilting and
`zooming. The fix focus lens cameras 2 may be used for creating an overview image of
`an area surrounding the combined camera ar-20 rangementarrangement 101. If, for
`instance, four fixed cameras 2 are placed approximatelygoo 90.degree. apart on the
`mounting rail g,9, a 360°360.degree. view may be achieved. Depending on the
`viewing angle of the fixed cameras, a 360°360.degree. view may be achieved with
`fewer cameras, for instance three fixed cameras 2 placed approximately120°
`120.degree. apart. When using the combined camera arrangement 101,25 the PTZ
`camera 17 may be directed to points of interest identified in the overview image
`created by the fixed cameras 2. Hereby, objects or persons may be tracked throughout
`the area covered by the cameras 2, 17 of the combined camera arrangement 101,
`while still maintaining an overview of the area.
`
`30[0041] When mounting the combined camera arrangement 101, the environment
`surrounding the combined camera arrangement 101 may be such that one or more of
`
`
`
`7
`
`AXIS EXHIBIT 1020-11
`
`

`

`the fixed cameras would have all or parts of the field of view blocked by objects, such
`as building walls. In such case, the predetermined
`9 positions of the fixed cameras 2 may not be suitable. However, the holders 2 allow
`the fixed cameras 2 to be moved to more suitable positions along the mounting rail 9.
`Should, for instance, one of the predetermined positions on the mounting rail 9 entail
`that one of the fixed cameras be pointing into a wall,5 the fixed cameras may be
`moved closer together along the remaining portion of the mounting rail, such that
`they provide more overlap in the useable field of view surrounding the combined
`camera arrangement. Similarly, should the camera arrangement 101 be placed
`indoors, it might not be allowable to monitor persons walking past outside a window.
`Also in this type of situation,1 0 it may be desirable to adjust the positions of the fixed
`cameras 2 so as not to monitor a certain part of the surrounding area, but to use the
`fixed cameras 2 to get good coverage of the remaining surrounding area. It will be
`appreciated that a person skilled in the art can modify the above described
`embodiments in many ways and still use the advantages of15 the invention as shown
`in the embodiments above. As an example, although reference has here been made to
`monitoring devices in the form of cameras, other monitoring devices may be used
`instead. Examples of such monitoring devices include IR detectors and microphones.
`
`[0042] Instead of, or in combination with, cameras employing visible light, the20
`cameras of the combined camera arrangement may comprise IR cameras, or thermal
`cameras.
`
`[0043] The fixed monitoring devices need not necessarily each contain their own
`electronics. Instead, the electronics necessary for the two or more fixed monitoring
`devices may be arranged at one, common location.
`
`25[0044] In the embodiment described above, there are four fixed monitoring devices.
`However, another number of fixed monitoring devices may bearrangedbe arranged in
`the camera arrangement. Depending on the local conditions in the place where the
`monitoring device arrangement is mounted, it may be possible to create a desired
`overview with three, or as few as two fixed monitoring30 devices. In other instances,
`it may be desirable to have more than four fixed monitoring devices. For instance, a
`combination of a number of fixed cameras and other monitoring devices may be
`arranged on the mounting rail.
`10
`
`[0045] When the camera arrangement has been mounted, it may be possible to
`supplement it with more monitoring devices.
`
`[0046] The monitoring devices may be removable from the holders, allowing
`exchange of monitoring devices for maintenance or for changing from one5 type of
`monitoring device to another.
`
`
`
`
`8
`
`AXIS EXHIBIT 1020-12
`
`

`

`[0047] In the embodiment described above, the fixed cameras are fix focus lens
`cameras, but cameras capable of zooming may be used instead.
`
`[0048] The number of recesses or notches in the mounting rail need not necessarily
`be three or four. A smaller or larger number of recesses may be pro-1 0 videdprovided
`depending on the number of predetermined positions to mark. Further, the
`predetermined positions may be marked by recesses of other shapes than the notch
`shown in FigFIG. 2, such as through holes and blind holes.
`
`[0049] The mounting rail and the holders, respectively, may be formed such that
`locking of the holders is only possible in the predetermined positions.15 They may be
`achieved, e.g., by suitable shapes of the recesses and protrusions. However, generally,
`it is preferable to allow an infinitely variable positioning of the holders on the
`mounting rail.
`
`[0050] Instead of the recesses, the mounting rail may be provided with protrusions
`marking the predetermined positions. In such case, the holder may be20 provided
`with a corresponding recess for engagement with the protrusions.
`
`[0051] In the embodiment shown in FigFIG. 5, a PTZ camera is placed in the opening
`of the camera arrangement. However, the pannable and/or tiltable monitoring device
`may be another kind of camera or monitoring device. The camera arrangement may
`in some instances be mounted without a central,25 pannable and/or tiltable
`monitoring device. For example, a spotlight or loudspeaker may be mounted in the
`opening. In some instances it may even be desirable to have no other device in the
`opening of the camera arrangement. In such case, the opening may be covered by a
`lid.
`
`[0052] The magnet may be a permanent magnet, e.g., a neodymium magnet.30 In one
`embodiment, the magnet may have two magnetic poles and be pivotable, such that it
`locks the holder in place when oriented in one direction, and releases the holder
`oriented in the opposite direction.
`11
`
`[0053] Instead of permanent magnets, electro-magnets may be used. In such case, it
`is preferable if the action of the electro-magnet be arranged such that when the
`monitoring device is supplied with electric current, the electromagnetelectro-magnet
`is turned off, and such that it is turned on when the electric power5 supply is
`interrupted. Thereby, the fixed monitoring devices are locked securely in position in
`the case of a power outage.
`
`[0054] The arrangement of the magnet and the ferromagnetic material may be
`reversed, such that each holder comprises ferromagnetic material, and the mounting
`rail comprises magnets. The ferromagnetic material used in the10 mounting rail or
`
`
`

`
`

`

`in the holder may be martensitic stainless steel, but other ferromagnetic materials
`are also possible.
`
`[0055] Instead of lock devices employing magnets, the holders in the monitoring
`device arrangement may have lock devices employing other means. For instance,
`each holder may be provided with a spring or a snap lock. Exam-15 piesExamples of
`additional embodiments of holders are shown in FigsFIGS. 7-9.
`
`[0056] In FigFIG. 7, a lock device 215 of a holder 208 employing spring function is
`shown. The lock device 215 is essentially made up of bent sheet metal. At the front of
`the lock device 215, i.e. the part of the lock device 215 which is arranged at the
`radially outer rim of the mounting rail, the lock device 215 has20 two release tabs
`220. By pressing the release tabs 220 towards each other, the lock device 215 is
`released, such that the holder 208 may be moved slidingly along the mounting rail to
`a desired position. Similar to the embodiment described above in connection with,
`e.g., FigFIG. 3, this holder 208 has hooks 210 for retaining the holder 208 on the
`mounting rail even when the lock de-25 vicedevice 215 is released.
`
`[0057] In FigFIG. 8, another embodiment of a holder 308 having a lock device 315
`employing a snap lock is shown. This holder 308 is essentially made of plastic, and
`the lock device 315 comprises a curved metallic bar 319 which is connected to a lock
`lever 320. Similar to the embodiments already described,30 the holder 308 in FigFIG.
`8 has hooks 310 for retaining the holder 308 on the mounting rail, even when the lock
`device 315 is released. In the locked position, as shown in FigFIG. 8, the lock lever
`320 positions the curved bar in a position where it presses against the underside of
`the mounting rail, thereby lock
`
`12inglocking the holder 308 in position on the mounting rail. When the lock lever 320
`is pivoted forwards, i.e. in a direction radially outwardly, the curved bar 319 is
`rotated such that it no longer presses against the mounting rail. The holder 308 may
`then be moved slidingly along the mounting rail.
`
`5[0058] As may be seen in FigFIG. 9, combinations of features of the different
`embodiments of holders that have been described are also possible. Here, the holder
`408 is of a type similar to the one shown in FigFIG. 7, and may be made essentially of
`sheet metal. However, the lock device 415 is of the type shown in FigFIG. 8,
`comprising a curved metallic bar 419 and a lock lever 420. In FigFIG. 9,10 the holder
`408 is shown with the lock lever 420 in the locking position, in which the curved bar
`presses against the mounting rail 409. Thus, the holder 408 and the fixed camera 402
`are held securely in position on the mounting rail. If the lock lever 420 is pivoted
`forwards, i.e. radially outwardly, the lock device 415 is released in the same way as
`described in connection with FigFIG.15 8. With the lock device 415 released, the
`holder 408 with the fixed camera 402 may be moved along the mounting rail 409 to a
`desired position in a sliding motion. The lock lever 420 may be made long enough to
`
`
`

`
`

`

`protrude radially outside the outer rim of the mounting rail 409 such that it prevents
`replacing the protective window (not shown in FigFIG. 9) when in the unlocked
`position. In20 this manner, it may be ensured that a person installing the monitoring
`device arrangement does not accidentally forget to lock the locking device 415 before
`closing the monitoring device arrangement. Once the arrangement is locked and
`closed, the fixed cameras 402 are held securely in place on the mounting rail 409,
`protected by the shielding portion 403 and the protective25 window.
`
`[0059] Other types of locking devices are also possible, such as locking devices
`employing rubber bands, clamping screws or tension bolts. Advantageously, locking
`devices not requiring tools for locking and releasing are used, thereby simplifying
`installation and adjustment of the monitoring device30 arrangement.
`
`[0060] In the embodiments shown, the holders are intended to be moved manually
`along the mounting rail. However, there may be situations where it is useful to be
`able to move the holders by remote control. This could be of
`13 interest if the monitoring device arrangement is mounted in a location that is
`difficult to reach, e.g., high up on a wall or pole. A remote-controlled movement of the
`holders may be achieved using a toothed rim on the mounting rail. The inner rim or
`the outer rim or both rims of the mounting rail could be5 provided with teeth, and the
`holder be provided with corresponding teeth. A motor, such as a piezoelectric motor,
`could be provided in the holder for moving the holder along the toothed mounting rail.
`It should be noted that the manual as well as the remote-controlled movement of the
`holders
