Description:
A SECURITY SYSTEM THIS INVENTION relates to a security system.

It is known that some security systems are configured to be triggered by certain events such as intrusion, the presentation of smoke, and the like, which may indicate a threat to an item of property monitored thereby. The invention relates to a security system of this general type. Such events will herein be referred to as trigger events.

According to the invention there is provided a security system which includes an electronic control circuit which includes means for receiving an input indicative of a trigger event; a transmitter compatible with a cellular communications network; and a memory for storing a contact number of a remote telecommunications device, the control circuit being configured to operatively, in response to receiving an input indicative of a trigger event, transmit via a cellular communications network to which it is connected an output signal indicative of the trigger event to a remote telecommunications device of which the contact number is stored in the memory.

To provide for communication via a cellular communications network, the control circuit may include a Subscriber Identification Module (SIM) card holder for holding a SIM card.

The security system of the invention may be configured for installation on an item of property, such as a house, an office building, a vehicle, and the like, to alert a user at the predetermined remote communications device of a potential threat to the item. The security system provides for this to be achieved without the involvement of a security company. As such, it is submitted that the security system of the invention provides a potential cost saving to a user.

The invention is described below, by way of three examples of a security system, in accordance with the invention, with reference to and as illustrated in the accompanying diagrammatic drawings. In the drawings: Figure 1 shows a diagrammatic elevation of a room, a first embodiment of a security system, in accordance with the invention, installed in the room, and a mobile phone outside the room; Figure 2 shows a diagrammatic layout of a part of the security system of Figure 1; Figure 3 shows a diagrammatic elevation of a room and a second embodiment of a security system, in accordance with the invention, installed in the room; and Figure 4 shows a diagrammatic plan view of a passenger car and a third embodiment of a security system, in accordance with the invention, installed on it.

In Figure 1, a first embodiment of a security system, in accordance with the invention, is designated generally by the reference numeral 10. The security system 10 is installed against a wall 11 of a room 12.

The security system 10 includes an electronic control circuit 14, including a memory, housed in a housing 16. It includes also a surveillance camera 18, connected to the control circuit via wiring in the form of a cable 22 ; a surveillance microphone 20, connected to the control circuit via wiring in the form of a cable 24 ; a trigger event sensor in the form of an infrared motion sensor 26 for sensing intrusion into the room 12, connected to the control circuit via wiring 28 ; and a trigger event sensor in the form of a smoke sensor 30 for sensing the presence of smoke in the room 12, connected to the control circuit via wiring 31.

The control circuit 14 is connected to a mains power supply of the room 12 via wiring 32.

With reference particularly to Figure 2, the control circuit 14 has an auxiliary power supply in the form of a rechargeable battery 34. The cable 22 of the camera 18 of Figure 1 has a spigot plug 40 via which it is connected to a socket 42 of the control circuit 14. Similarly, the cable 24 of the microphone 20 of Figure 1 has a spigot plug 44 via which it is connected to a socket 46 of the control circuit 14. As such, the control circuit 14 can receive form the camera 18 a video signal or a still image and from the microphone 20 an audio signal.

The wiring 32 is connected to a pair of connectors 48 of the control circuit 14.

The control circuit 14 includes means for receiving inputs in the form of a electronic signals from the sensors 26 and 28 of Figure 1 indicative of trigger events in the form of intrusion and the presentation of smoke, respectively, the means including pairs of connectors 50 and 51 to which the wiring 28 and 31, respectively, are connected.

The control circuit 14 includes a SIM card holder 52 in which a SIM card 54 is held. The control circuit 14 includes also a transceiver 56 and, via the SIWA card 54 and the transceiver, the control circuit 14 is connected in communication with a cellular communications network (not shown) and is associated with a contact number on the network.

The control circuit 14 has a keypad 58 via which it may be activated and de-activated and programmed also, as will be described below. It includes also an LCD display 59 for displaying keystrokes via the keypad 58 and, upon request via the keypad, items stored in the memory. Also, in the case of a trigger event triggering the security system 10 (see Figure 1), as will be described below, the type and location thereof are displayed on the display 59.

The control circuit 14 includes also a pair of connectors 64 serving as a switch which the control circuit can open or close. Via the connectors 64 and wiring 65 (see Figure 1 also), an external device in the form of a relay (not shown) of a light 66 (see Figure 1) in the room 12 is connected to the control circuit 14. As such, by closing the switch, the control circuit 14 can control the relay to switch the light on. By opening it, the light is switched off.

With reference particularly to Figure 1, a user (not shown) of the security system 10 is the owner of the room 12. He has a remote communications device in the form of a mobile phone 68. The control circuit 14 stores in its memory the contact number of the mobile phone 68. The contact number was programmed into the memory of the control circuit 14 via the keypad 58.

The control circuit 14 is capable of relaying a video signal or a still image received from the camera 18 to a remote device, such as a mobile phone or a personal computer in communication with it via the cellular communications network. The same applies to an audio signal received from the microphone 20.

The control circuit 14 stores in its memory also a passcode and a number of predetermined operation codes, each associated with a particular operation or a combination of operations which can be performed by the control circuit. All of these codes were programmed into the memory via the keypad 58. The control circuit 14 can receive, via the network, from a remote communications device such as the phone 68 or a personal computer (not shown), an input in the form of the communication of a Short Message Service message including the passcode and at least one of the operation codes.

In response to successful verification of the passcode, the control circuit performs the operation or combination of operations associated with the operation code. These operations include : arming and disarming of the security system 10; switching the light 66 on or off; relaying of a video signal or a still image received from the camera 14 to a remote device; and relaying of an audio signal received from the microphone 20 to a remote device.

It will now be assumed that the owner of the room 12 has activated the security system 10 via the keypad 58 before leaving the room. An intruder (not shown) has subsequently broken into the room 12 and is detected by the sensor 26. The sensor 26 responds by transmitting to the control circuit 14, via the wiring 28, an input in the form of an electronic signal representing a trigger event of a type intrusion. The control circuit 14 responds by transmitting a communication to the mobile phone 68 including an SMS message including the text"intrusion". Had the trigger event been the presentation of smoke, the text would have been"smoke".

The owner sends from his phone 68 to the contact number of the control circuit 14 an SMS message including the passcode and an operation code for switching on the light 66 and transmitting images received from the camera 18 and an audio signal from the microphone 20 to the phone. The control circuit 14 responds by switching on the light 66 and activating the camera 18 and the microphone 20. The camera 18 captures images of the inside of the room 12 at predetermined time intervals, say ten seconds, and transmits them to the control circuit 14 via the cable 22. The control circuit 14 responds by transmitting a signal incorporating each image as it is received to the mobile phone 68, via the cellular communications network. The phone 68 displays each image on a display thereof. The microphone 20 captures ambient sound in the room 12 and transmits them in real time to the control circuit 14 via the cable 24. The control circuit 14 responds by transmitting a signal incorporating the sound in real time to the mobile phone 68 via the cellular communications network.

By using a different operation code, the owner may instruct the control circuit 14 to relay a video stream captured by the camera 18 in real time to the remote communications device.

The user 60 may thus respond to the intrusion as he deems fit.

In Figure 3, a second embodiment of a security system, in accordance with the invention, is designated generally by the reference numeral 70. The security system 70 is installed against a wall 72 of a room 74.

The security system 70 includes many features that are similar to corresponding features of the security system 10 of Figure 1. Like features, where designated, are thus designated again by the same reference numerals as before and a description of these features may be found in the description above of Figures 1 and 2.

The security system 70 includes a surveillance camera 76, an infrared motion sensor 78, and a surveillance microphone 80, each of which has a built-in RF transceiver (not shown).

The control circuit 14 includes a matching transceiver (not shown). As such, the sensor 78 can transmit a predetermined input in the form of a radio frequency signal to the transceiver of the control circuit 14. The camera 76 can transmit an RF video signal to the transceiver incorporating video captured by it. Similarly, the microphone 80 can transmit an audio signal to the transceiver incorporating audio captured thereby.

By communicating RF signals to the camera 76 and the microphone 80, the control circuit 14 can control their operation.

Furtherfeatures of the operation of the security system 70 are similar that of the security system 10 of Figure 1 and, as such, will not be elaborated on herein.

In Figure 4, a vehicle 84 has fitted thereto a third embodiment of a security system, in accordance with the invention, designated by the reference numeral 86.

The features of the security system 86 are generally similar to those of the security system 10 of Figure 1 as described above. As such, the features of the security system 86 will not be described in detail below.

The security system 86 includes a control circuit 88 identical to that of the control circuit 14 of Figures 1 and 2, except that it is configured to be powered from a battery 90 of the vehicle 84. The control circuit is fitted under the hood of the vehicle 84. The security system 86 includes also a surveillance camera 92 and a surveillance microphone 94, both of which are hidden in the dashboard of the vehicle 84. When activated, the camera captures images of a driver (not shown) of the vehicle 84 and transmits it to the control circuit 88. The microphone 94 records ambient audio and transmits it to the control circuit 88. The security system includes also an infrared motion detection sensor 96.

In similar fashion to that in which the control circuit 14 of the security system 10 of Figure 1 is capable of switching the light 66 of Figure 1 on and off, the control circuit 88 can activate and de-activate, via a relay 98, an immobilizer system of the vehicle 84. As before, such immobilization occurs upon sending, from a remote mobile phone, a required SMS message to the control circuit 88.

Since certain cellular communications networks are capable of performing tracking of compatible mobile communications devices connected to them, the security system 86 may effectively permit tracking of the vehicle 84 if used in conjunction with such a network.

Further features of the operation of the security system 86 are analogous to that of the security system 10 of Figure 1 and, as such, will not be described in relation to the former system.
