Description

The present invention relates to a window or door for installation in a building, and to monitoring systems comprising a door or window sensor.

Background Illegal - entrance to the premises is a long-standing problem and electronic and / or electronic systems have been available for decades to detect the opening of doors and windows in homes and businesses and to activate some form of alarm. Although the percentage of homes using such systems has historically been relatively small, such systems are increasingly being retrofitted to a wide variety of spaces. Such systems often detect the opening of a door or window using a magnetic sensor arrangement having a magnet and a magnetic sensor, such as a tongue switch or magnetometer, mounted on two relatively movable parts, such as a frame and a door or a frame and a hinge or sliding frame, respectively. When the door or window is closed, the magnet and the sensor are close enough to each other so that the sensor is inside the magnetic field of the magnet so that, for example, the tongues of the tongue switch remain in contact. When the door or window is opened even slightly, the magnet and the sensor move apart, reducing the strength of the absence magnetic field detected by the sensor, thus causing the sensor to change state. Detecting the opening or closing of a door in this way is of interest not only in the context of security, but also, and increasingly, in the context of so-called “smart home” installations. or cooling, and / or may be configured N to turn off the air conditioning when it detects the opening of a window g Such sensors and magnets are typically surface mounted 2 30 - on suitable surfaces of interoperable elements, whether z is installed during installation / commissioning or retrofitted = it The installation magnet and sensor & are typically mounted on surfaces that are visible even when the door / window is closed N, despite the disadvantage it causes to the aesthetics of the interior of the premises, and O 35 - more importantly the risk that the visibility and> accessibility of the magnet and sensor will increase the likelihood of sabotaging or disabling the system. However, sometimes the magnet and / or sensor may be hidden in a hole cut or drilled in the side of the frame / door / window, although cutting or drilling holes in a modern window or door may significantly impair their structural integrity and / or insulation properties, and attempting to form such holes may result in - significant damage due to holes being formed at inappropriate locations.

In addition, the on-site monitoring system sensor installer is unlikely to know where it is safe to remove parts from the window or door structure, which means that the choice is potentially surface-mounted - and even then surface mounting may require machining of holes for screws or rivets - and between compromising the structural integrity of the door or window by cutting holes to hide the components.

In some control installations, the door or window may be equipped with an impact sensor instead of or in addition to a magnetic contact sensor, but the same problems - essentially with the impact sensor installation - are not required to work with the impact sensor if an accelerometer is used.

EP3053152B1 discloses alarm equipment as part of a wireless alarm system or smart home system that can be retrofitted to non-invasively existing building entrances, such as windows or doors, without compromising the design aesthetics of the home.

The elongate sensor assembly with a maximum height of less than 5 mm is arranged to co-operate with the magnet, the elongate sensor assembly and the magnet are configured laterally displaced relative to an opening, cavity or cavity formed by the window or door and the corresponding frame in the closed window or door position.

Although the proposed solution can reduce the visual disturbance caused by conventional sensor installations, such a sensor configuration is not suitable for all doors or windows.

There is also a risk that damage factors g may remove such sensor assemblies if the window or door 2 30 is left open. z Therefore —there is a need for an improved approach to the installation of door / window sensors, where the magnet and sensor are substantially hidden from view with the door / window closed and therefore better protected against N tampering.

DETAILED DESCRIPTION Figure 1 shows a detail of a window or door for installation in a building, the window or door comprising a pair of portions 10 and 12, the portions comprising a frame 10 defining an opening and a closure portion 12 movable relative to the frame 10 between an open and a closed position. The first sleeve 11 is fixed inside the first slot in the first of the parts, in this case in the frame 10, the first sleeve 11 has an externally opening first recess 14 configured to receive the sensor unit. The second sleeve 13 is mounted inside the second slot in one of the parts, in this case the closure part 12, the second sleeve has an externally opening second recess configured to receive the magnet for operating the magnetically activated sensor.

In the example shown, the closing part is the hinge frame of the window. The figure shows the cooperating portions of the frame 10 and the hinge frame 12, here seen from inside the lower left corner of the window. The hinge frame is hinged to the frame part not shown on the right side of the figure. The inner side of the frame has a weather sealing flange 28 which extends upwards from the base rail 16 and inwards from the side rail 18. When the window is closed, the inner side 20 of the hinge frame closes against the flange 28. This flange may be provided on its outer surface with a flexible dust seal, not shown. An additional sealing structure, not shown, may also be provided on the upper surface of the base rail 16 and on the respective side of the side rail 18, the additional sealing structure sealing the hinge frame against the respective surfaces when the window is closed. The side rail 18 can - of course, be vertical, separating one window element from another. Of course, the window may also have more than one openable element, for example one or N several hinge frames, and optionally one or more upper windows. Each of the openable & elements and their fixed counterparts is preferably provided with a sleeve, as shown generally in Figure 1. Details of the glazing of the hinge frame 12 are not shown in Figure 1.

z Slots for bushings can be formed in the respective + base before the base is formed as a hinge frame or frame, or slits & can be formed after the construction of the relevant part but before joining the parts N (ie the hinge frame and the frame). The O 35 slots for the sleeves can likewise be made before or after the glazing of the window, for example before the glazing of the hinge frame 12. It is to be understood that, as shown in Figure 1, the glazing would be mounted against the side 21 of the vertical side rail and against the upper side 22 of the bottom rail 23 of the hinge frame 12.

The window is shown assembled from extrudates, with some exemplary internal details in the form of ribs 24 and 25 shown for the base rails of the frame and hinge frame. The extrudates may conveniently be made of an aluminum alloy or a plastic material such as unplasticized polyvinyl chloride (uPVC). The use of extrudates, such as aluminum or plastic materials, is of course not necessary, as the windows or doors according to embodiments of the invention may also be made of wood, and the windows and doors may of course be made of a combination of plastics, metals and wood. The figure shows the first sleeve 11 in partial shadow - the dotted lines indicate features not actually visible in the view shown, mounted inside the first slot in the frame 10. The first sleeve 11 has an externally opening first recess 14 configured to receive the sensor unit. The sensor unit is not shown here. The sensor unit and optionally also the corresponding magnet for operating the magnetically activated sensor are generally not installed until the window / door is installed in the building. The windows and doors according to embodiments of the invention are thus generally manufactured and transported with the sleeves in place, but without the sensor unit and magnet. This is because it has been found advantageous for the person installing the control system to optimize the system to accommodate the expected loss of radio frequency signal received by the control system controller or central unit due to the installation of the sensor unit inside the window or door frame. For example, if the sensor unit is installed in a window with an aluminum frame, the signal strength N received by the central unit can be up to 20 dB lower than would be expected from a surface-mounted sensor. & This additional attenuation level should generally be manageable with good RF design g, but may require tuning the RF settings of the RF transmitter / - 2 30 transceiver in the sensor and corresponding receiver in the system control unit. Lower attenuation levels = are likely in both uPVC and timber windows and doors. In fact, the metal structure of a window or door can sometimes provide one or more cavities that effectively act as Faraday cages, so that placing an O 35 sensor unit in such a cavity effectively prevents the sensor from communicating with the central unit of the control system. Such situations can generally be predicted from an analysis of the window / door structure, and can in any case be determined simply by trial and error.

The figure also shows a complete shadow view of a second sleeve 13 attached inside the second slot in the hinge frame 12, the second sleeve 13 having an externally opening second recess configured to receive a magnet for operating the magnetically activated sensor.

When the window is closed, the open first recess and the open second recess face each other, as shown in Figure 2, thus covering the sleeves for the most part or completely.

The two sleeves are thus hidden when the window is closed.

It should be noted, however, that when the window is open, not only are the bushings visible, but they can also be exposed to sunlight.

For this reason, it is advantageous to make sleeves from UV-resistant plastic materials whose structural strength is less likely to be affected by UV radiation.

In particular, if the sleeve is made of white plastic, yellowing or other discoloration of the plastic due to UV radiation can also be a problem if care is not taken to select a UV-resistant plastic.

UV resistance can be achieved by using a suitable additive or additive combination, and / or by selecting a suitable base plastic.

For example, various polycarbonate plastic blends (PCs) have proven to be highly resistant to solar radiation even when formed white.

Polycarbonate, which is also an excellent plastic for injection molding, is as such a preferred material for making sleeves.

Fig. 2 is a schematic cross-sectional view taken along lines A-A of Fig. 1 for both the frame 10 and the hinge frame 12 when the window is closed.

It shows the externally opening second recess 32 of the second sleeve.

The glazing of the hinge frame is shown & schematically by a unit 36 containing a seal 38. g As a general rule, it is preferable to mount the sensor unit in a fixed part of a window / door rather than a moving part, as the sensor unit is more sensitive to rain and shocks. / to the door part, such as the hinge frame shown in Figures 1 and 2, & to the mounted element, especially if the window or door opens outwards.

This is also the case if the sensor unit is configured to detect an impact, i.e. if it is based on an O 35 accelerometer (discussed below), instead of or in addition to the presence of a magnetic contact switch.

Figure 3 shows in a simplified form a second window according to an embodiment of the invention. In this case, the window includes a pair of sliders 40 and 42 for installation within the opening 44 defining frame. The two parts 40 and 42, which may also be referred to as sliding frames, can be moved relative to each other and each defines a closing part which can be moved relative to the frame 44 between an open and a closed position. When the window is closed, the converging frames of the two parts overlap in the sense that the right converging frame of the outer part 40 is located in front of the left converging frame of the rear part 42. This converging framework typically has the same width, although this is not necessary. A first sleeve, not shown, is attached to the first slot on either the rear side of the converging frame of the outer portion 40 or the first slot on the front side of the converging frame of the rear portion 42. The first sensor unit has a first recess configured to receive the sensor unit, the sensor unit including a housing, a magnetically activated sensor, a microprocessor, a radio frequency transmitter and a battery. The second sleeve, which is attached inside the second slot in one of the parts, the second sleeve is configured to receive a magnet for operating the magnetically activated sensor. The first and second recesses are facing each other, and the first and second sleeves are hidden from view when the window is closed. Each of the first and second recesses has - an open side, the two open sides facing each other with the window closed. Note again that the two bushings are hidden when the window is closed.

Fig. 4 is a schematic cross-sectional view taken along lines B-B of Fig. 3. The outer portion, i.e. the sliding frame 40, has a converging frame 46 shown as containing a second sleeve 48, while the innermost portion or sliding frame 42 has a converging frame 50 containing a first sleeve 52. The open sides of the two N sleeves are facing each other with the window in the closed position, such as & shown. Each sliding frame is glazed, the position of the glazing is indicated. Also shown are bottom tracks 54, 56 on which the two sliding frames 40 and 42 can slide when the window lock, not shown, is released. Incidentally, the window lock z is typically arranged in respective portions of the two converging frames 46 and 50, = but the lock may additionally or alternatively be arranged between each of the sliding frames and the frame 44. The sensor is installed in the innermost sliding frame rather than the outermost sliding frame, so that the second sliding frame is not in the signal path of the sensor O 35 radio frequency transmitter / transceiver and the system control unit> radio frequency transceiver, thus avoiding potentially significant unwanted attenuation.

Although there may be enough material in the frame to allow the sleeves to fit without significantly interfering with the strength and structural integrity of the frame and thus the window, this is less likely where the window is configured as a regular sliding window with two sliding frames moving vertically between open and closed. In such a situation, it is typically advantageous to mount the sensor on a fixed frame, one sensor for each slide, and each slide includes a magnet for the corresponding sensor.

Instead of mounting a single sensor unit on the rails facing the two sliding frames, as shown in Figures 3 and 4, a sensor unit and a corresponding magnet could of course be arranged on each side of the window so that one sensor assembly is provided for each of the two sliding frames (sliding unit). indicated by the dashed rectangles 45 in Figure 3. The preferred configuration is in fact that each sensor unit is mounted on a fixed inner element of the frame, although it requires the use of two sensor unit installations instead of only one. This is due in part to the fact that the location of the sensor unit (s) is fixed, and the RF power of the sensor unit (s) is likely to be more consistent, reducing the variation in signal strength detected by the controller of the control system. The electronics of the sensor unit are also less likely to experience repetitive mechanical shocks and impulses than if they are mounted on a moving part that may be ejected or closed. Any such side-mounted sensor units are preferably located away from both the hinges and the locks / latches in order to maintain the structural integrity of the frame and the like. Fig. 5a schematically shows in cross-section a detail of how the sleeve can be retained inside a door or window part according to an N embodiment of the invention. The sleeve 60, which may be the first or second sleeve, g is shown here in cross-section inserted into a slot in the window or door part 62, part 2 30 62 is also shown in cross-section. The sleeve 60 is received inside the portion 62 and the recess 64 of the sleeve 60 points outwards, away from the portion 62. The open end of the recess 64 = is flanked on each side of the sleeve 66 by the flange to hide the edges of the gap formed in the window & door portion 62. The dimension of the flange may not be the same on all four sides of the N-sleeve, for example the first sleeve used to receive the O 35 sensor unit may be in the form of an elongate rectangle> with two long sides separated by two shorter ends, and the flange may be arranged on all four sides, that the flange covers the edges of the gap in the part which receives the sleeve. With such an assembly, the flange portions at the two shorter ends may extend beyond the flange portions at the long sides, and additional fastening means, such as a screw or rivet, may be provided at each of the two shorter ends to secure the sleeve to the window / door portion. Examples of such an arrangement are shown in Figures 6 and 7, which will be described later.

Returning now to Figure 5a, it can be seen that the sleeve 60 includes a protrusion 68 on each side extending from the sleeve 60 to the underside of the portion 62 so that the edges of the portion 62 defining the slot are located between the protrusion 68 and the flange portion 66. The protrusions 68 are designed to provide a latch fit to the window / door portion so that once the sleeve is inserted, it is difficult or even impossible to remove the sleeve without damaging it or the portion into which it is inserted, especially if the sleeve comprises a sensor unit or magnet. It is generally preferred to provide a multilingual latch fitting assembly, as shown schematically in Figure 5b, rather than a single unitary latch fitting feature on each side of the sleeve. Such a multilingual latch fitting assembly is shown in Figure 5b, which is a schematic perspective view of the longitudinal portion of such a sleeve. The sleeve is provided with 2 latching tongues 68 shown on the nearest long side, although practically much more latching tongues can be provided on each external long side. If a latch fitting assembly is used in the sleeve for the sensor unit, it may be advantageous to provide the latch fitting features only on short sides, as this can help minimize the effective length of the sleeve body that must fit into the window / door section: this can be a problem especially if the door / window section includes internal ribs or other - properties that may affect the latch fit properties. Flap matches can optionally be arranged only on long pages, only on short pages, or even N on all four pages, although this is less advantageous. Of course, any type of latch fitting assembly can also be provided for both g-sleeve types, and not just the sensor unit receiving sleeves. 2 Figure 6 shows examples of sleeves, sensor units, and compressed z magnets for use with sensor units. 600 generally shows = sensor unit 602 partially inserted into sleeve 604. Sleeve 604 includes & essential flanges or “ears” 608 at each end, and each ear includes a through hole N 610 for receiving a screw or other fastener to secure the sleeve O 35 window - or the part of the door into which it is inserted. Preferably, non-metallic fasteners are used to secure the sleeves to the door or window to avoid further contributing to radio frequency attenuation and scattering.

Although not easily visible from the image, each end of the sleeve also includes an optional latch fit feature 611 that ensures that when fitted to a suitably sized door or window portion, the sleeve cannot be easily removed without damage. Once the sleeve has been fitted, it cannot preferably be removed - with the sensor unit or magnet inside it (in the appropriate sleeve type) without destroying the sleeve or significantly damaging the window / door. Each ear 608 may also include a pair of structural flanges 612, as shown, each flange including a protrusion cooperating with corresponding flange portions 614 on the underside of the dome 616. Each dome includes a protrusion or tongue 618 that - acts to hold the sensor unit 602 in place within the sleeve 604, as can be better seen from the assembly shown as 620. Also shown in the two configurations 600 and 620 are cutting openings 617 formed approximately at the center of each long side of the sleeve, which allow the sensor unit inside the sleeve to be gripped with a finger and thumb so that the sensor unit can be removed to allow the battery to be replaced.

Figure 6 also shows two magnet / sleeve assemblies generally indicated as 640. As best seen in the assembly on the right side of the figure, the sleeve 642 is provided with latch fitting tongues 644 at each end and cooperates with the material surrounding the slot in which the sleeve is mounted when mounted on a window or door. The sleeve also includes flanges or lugs 646 at each end, and also optionally a narrow flange along each long side. These flanges prevent the sleeve from sinking all the way into its receiving slot, and they also act to hide the edges of the slot. As can be seen, the sleeve 642 against the magnet 648 has open sides, which is optional but advantageous because it can help eliminate potential problems when injection molding the N sleeve, and also facilitates placement of the magnet within the smaller & bottom area. Both types of sleeves can be conveniently formed by injection molding using a suitable engineering plastic such as ABS, HDPE, 2 polypropylene, polycarbonate, HDPC or polyamide. As mentioned earlier, the choice of a UV-z resistant polymer composition or blend optionally containing + one or more UV stabilizers is preferred because it is likely that & sleeves may be exposed to direct or indirect sunlight when the window / door to which the N-sleeves are exposed. is installed, is open. Although the sleeves could potentially be made of O 35 metal, such as aluminum alloy, it is much less advantageous than the use of a plastic material, largely due to much greater attenuation of radio frequency signals transmitted by the sensor unit - an important consideration if an external antenna is not used. In fact, even when choosing a plastic material for the manufacture of a sleeve, it makes sense to take into account its radio frequency properties, in particular its transmittance. From this point of view, poly (p-phenylene oxide) or poly (p-phenylene ether) preferably blended with polystyrene or styrene-butadiene copolymer or polyamide is potentially highly desirable due to its low attenuation of these radio frequencies, these frequencies may be below the European gigahertz or equivalent in other bands), or in the 2.4 GHz ISM band (used for Zigbet, Bluetooth, and WiFi).

The "worksheet" 650 of the magnet, which is neither the north nor the south pole of the magnet, is shown at the top in the magnet / sleeve assembly shown on the left side of the figure. preferably one selected to provide a low friction effect with the material used to form the sleeve 642. so that the magnet 648 can be easily inserted into the sleeve 642. For example, the sleeve can be made of polycarbonate and the magnet can be encapsulated in a PTFE polymer sheath. The encapsulated magnet has a tight sliding fit into the sleeve, and it is highly desirable for the sensor unit to have a tight sliding fit into its sleeve, as this can eliminate “noise” in the sensor system and also help ensure good transmission of any mechanical shocks to the door or window. to the impactor (if used). Keep in mind, however, that while the magnet may not need to be removed from its socket once it is installed, the sensor unit is battery-powered and will therefore likely need to remove its N socket from time to time to replace the battery (ies). To facilitate the insertion & removal of the sensor unit into and out of the sleeve, it is useful to ensure that the sleeve includes one or more openings or air holes at the bottom of the sleeve or 2 30 (if the sleeve is not open) so that air can be displaced from the sleeve z and air can enter the cavity when = the sensor unit is removed. & Fig. 7 generally corresponds to Fig. 6, but shows an open-sided sleeve 700, S having actually full walls 702 only at each short end, but not S 35 along the long sides. Instead, each long side includes two vertical ribs or> wall portions 704. These rib or wall portions 704 protrude from the base 706, their length (or height) being substantially the same as the height of the end walls 702 - so that their upper ends end up with the circumference of the slot into which the sleeve is received. .

Thus, the ribs 704 function both to guide the sensor unit into the sleeve and to prevent it from inadvertently entering the interior cavity of the door or window outside the boundaries of the sleeve - in short, the presence of ribs facilitates the correct placement of the sensor unit.

By using ribs instead of full side walls, as shown in Figure 6, it may also be possible to reduce the width of the space required to accommodate the sleeve and sensor unit - so that it may be possible to install the sensor unit in a narrower portion of the door or window.

This can be further facilitated by reducing the thickness of the ribs so that they extend - as little as possible beyond the width of the sleeve recess, in line with the ribs performing their positioning / retaining function.

As with the sleeves shown in Figure 6, the sleeve 700 includes latch fitting elements at each short end, as well as the dome and dome features described with reference to Figure 6.

It is contemplated that the manufacturer of the doors / windows in accordance with aspects of the invention will machine the slots to receive the first and second sleeves based on knowledge of the internal structure of the elements in which the sleeves are installed.

Machining could preferably be performed before the essential - components - are assembled - to make a sliding frame / hinge frame / closure or frame, thus having the advantage of maximum freedom to position the workpiece for machining, or machining after sliding frame / hinge frame / closure but before sliding / connecting the hinge frame / closure to the frame.

If machining is carried out before the essential components are assembled to make a sliding frame / hinge frame / closure or frame, it may also be practical to apply internal or external protective or decorative surface treatments & to improve the durability of the finished door or window, which is advantageous. g Machining can also be done before or after glazing windows or doors 2 30.

Performing machine work before glazing the units z eliminates the risk of damaging expensive glazing units during machining, = and the units are also considerably lighter and thus easier to handle than when glazed.

N It is also considered that the door / window manufacturer may introduce sleeves O 35 before packing the windows / doors for transport (assuming they are> not built at the place of use). Thus, an aspect of the invention is a door or window that includes an installed sleeve for receiving a sensor unit, packaged for chartering or transportation.

Such a packaged door or window generally does not include a sensor unit within the sleeve.

If the door or window is to be used with a magnetic sensor, the packaged door / window may already have the appropriate magnet installed (with or without a sleeve for the magnet). Alternatively, the packaged door or window does not include a sensor or magnet for use with the sensor, but includes a sleeve for receiving both the sensor and the magnet.

If a window or door installation uses only an impact sensor instead of a magnetic sensor (i.e. an impact sensor using an accelerometer but not a magnetically activated sensor), which is an option considered for several aspects of the invention, then of course no other sleeve is required - only one sleeve would be provided, and it would be for the shock sensor unit.

For repetition, the window or door manufacturer would preferably install the sleeve.

It is contemplated that the bushings in the doors and windows according to aspects of the invention will be filled with sensors and magnets as needed only after the doors / windows have been installed.

This avoids unintentional damage to the sensor units during the installation of windows / doors and reduces the risk of sensors and magnets being stolen or lost during the installation and subsequent equipping of the premises.

The sensors are preferably installed only after the relevant - monitoring system has been installed / commissioned, as this offers the advantage that the performance of the door / window sensor together with the monitoring system can be optimized, for example by adjusting the radio frequency settings of the system controller and optionally the sensor unit (which may include , in order to also receive signals and commands from the control unit, instead of just the transmitter). However, the sensor (and, if necessary, the magnet) can optionally be mounted on the window or door before the window or door is installed. Fig. 8 schematically shows a possible configuration of the components g of the sensor unit 900 according to an aspect of the invention.

The unit 900 2 30 - comprises a housing 902. The printed circuit board, pcb, 906, supports the circuitry and functional component of the sensor unit z, including the processor 908, the first magnetic sensor 910, which may be a tongue relay or a similar or more complex sensor. such as a magnetometer, an impact sensor (e.g., an accelerometer) 912, an N radio frequency transmitter or, more preferably, a transceiver 914, an antenna O 35 assembly 916, and a memory 918.> to the mutual assembly, shown in particular in Figures 6 and 7, it may instead be located elsewhere in the sensor unit to accommodate a different positional relationship between the sensor unit and the magnet.

Optionally, as shown in Figure 8, the sensor unit may include more than one magnetic sensor (i.e., more than one tongue switch). The figure shows an assembly in which a second magnetic sensor (i.e., a tongue switch or magnetometer) 923 is positioned adjacent one end of the sensor unit for use with a magnet located near the end of the sensor.

When a sensor unit with more than one magnetic sensor (i.e., as shown in Figure 8) is connected to a particular monitoring installation, the sensor unit is configured, e.g., with the central unit of the monitoring installation, to use only a suitable magnetic sensor and ignore the other.

Alternatively, such a sensor unit may be configured to use the magnetic sensor that first responds to the presence of the magnet and to ignore any other magnetic sensor unless it is reset.

The housing 902 also includes a battery power supply 903, for example a pair of alkaline AAA batteries 905. The antenna assembly is preferably formed on and supported by the pcb 906, and may be formed in the conductive layer of the pcb, for example.

The Pcb may be arranged so that the housing of the unit may be configured or marked so that when the sensor unit is properly mounted on the sleeve, the antenna is at the open end of the sleeve instead of towards the bottom of the sleeve recess.

This is likely to reduce unwanted attenuation of radio frequency signals from the sensor unit.

The radio frequency transmitter or transceiver 914 preferably operates in the ISM frequency band, for which low energy consuming equipment is readily available in the ISM frequency band below European GHz (or the like in the other N bands), e.g., the 863-870 MHz band.

The radio frequency transmitter or & transceiver optionally operates in the 2.4 GHz ISM frequency band, g using a protocol such as Zigbe, Bluetooth or WiFi. Fig. 9 schematically shows the relationship between the main components z of the sensor module.

They have already been shown at least in Figure 8 and its description.

However, the processor = and the transmitter / transceiver may be arranged in a single & single common module 950 rather than as two separate units.

Fig. 10 is a schematic diagram showing the main elements of the installation of the security monitoring system O 35 according to an aspect of the invention. > Premises, which may be home premises or small business premises, are protected by a control system or installation, which may be called a security control system,

and wherein the controller or central processing unit 1010 is in radio frequency communication with various sensors / detectors / cameras scattered around the spaces. In the event that a fault condition occurs when the monitoring system is equipped, the central processing unit 1010 sends an alarm message to the remote monitoring station 1020, which - may also be called a central monitoring station. The monitoring station preferably includes human workers who can respond to alarm notifications by contacting the police, private security personnel, or other appropriate locations after viewing the images / video provided by the central unit 1010. The CPU is preferably connected to the Internet 1025 via both a wired broadband connection 1030 - (optionally via WiFi between the CPU 1000 and the local router) and one or more radio frequency connections, optionally including a 4G or 5G connection. The central monitoring station 1020 is connected to the Internet and the PLMN represented by the antenna 1021.

The installation includes doors 1040 and windows 1050, each of which includes a magnetic sensor 1055 as previously described to detect when the door / window is open, and each optionally includes an impact sensor of the type described above to detect attempts to enter or break a door or window. The installation may include at least one internal video camera 1060, which is preferably arranged to monitor the main entrances to the premises, i.e. the front and back doors. One or more external video cameras may also be provided. Cameras (which may include cameras that are included to take individual pictures instead of video) either include or connect a motion or presence sensor that can be arranged to trigger the taking of pictures in the event that motion or presence is detected. The installation may also include microphones that are optionally associated with one or more cameras. Each of the plurality of sensors is preferably battery-powered, and each includes a radio frequency N transmitter or transceiver for communication with the CPU 1000. & Radio frequency communications within the installation may use the ISM frequency band below European gigahertz (or equivalent in other regions), for example the 863-870 2 30 MHz band for which low energy transceivers are readily available, although the camera (s) may not be available ( vat) also be able to send images, = especially video to the CPU using WiFi or some other high & bandwidth channel. One or more of the camcorders may also be powered by the mains S when the battery is in standby, especially if the camera is used to monitor the S 35 and not only to record incidental events. For some> applications, it may be desirable to operate in the 2.4 GHz ISM band using protocols such as Zigbe, Bluetooth, and WiFi.

Although the publication focuses on the idea of a door or window manufacturer installing fittings in a door or window section to receive a sensor unit (including either an impact sensor or a magnetically activated sensor or both), it should be noted that the manufacturer could simply preform or machine machined slots against the sockets. to receive the sensor unit (and, if necessary, the magnet), leaving the fitting of suitable sleeves to the installer of the monitoring system. The relevant gaps would be closed (and optionally sealed) with blank plugs or other alternative closures fitted by the manufacturer, which could only be removed by the installer when the sensor (and - if necessary, the magnet) was installed. This option of fitting blank plugs or other closures instead of sleeves can, of course, be applied to any of the foregoing options and embodiments - and all such combinations have been considered where possible.
