Definitions

  • the present invention is directed to a security arrangement and method for monitoring the inside of a facility or residence.
  • monitoring devices such as cameras, motion sensors, keypads or contact sensors.
  • Many buildings have multiple locations that are monitored for security purposes, requiring multiple monitoring devices in the different locations.
  • the monitoring devices can be configured to communicate with one or more central control devices.
  • the central control device can, among other things, perform monitoring or recording functions, determine whether the building-security has been breached and whether to contact security personnel.
  • One method of communicating between the monitoring devices and the central control device is by a physical connection, such as electrical or other wiring.
  • a physical connection such as electrical or other wiring.
  • Using wiring to establish communication between the security devices can be troublesome for a number of reasons, such as the high cost of installation and maintenance. For example, exposed wiring is often unacceptable in a building, and thus, the installation of the security system requires passing the wires through the walls of the building. This type of installation can significantly increase the time required-to-oomplete a security system installation. Moreover, the troubleshooting and repair of the security system can be difficult because there is limited access to the unexposed wiring. The cost of the wire is another factor, especially in large buildings requiring numerous monitoring devices.
  • wireless security systems also have a set of problems, such as battery life.
  • the security devices would be self-powered by, for example, a battery.
  • Self-powered devices are more secure because they are not subject to failure upon loss of power to the building. They also require less installation problems because they do not need to be connected to a separate power source; however, self-powered devices often have reliability issues due to the finite life of their power source.
  • Increasing the useable time of a power source reduces the cost for replacement of the power source and increases the security of the entire system by having less potential downtime of the system or its components.
  • monitoring devices that contain digital cameras require enough power to run the camera, to store the digital picture in memory and to transmit the digital picture to the control device.
  • a wireless building-security system can be further complicated by industry or government regulations.
  • One such set of regulations is imposed by the Federal Communications Commission (FCC).
  • FCC Federal Communications Commission
  • the current regulations cover numerous aspects of wireless communications systems including, but not limited to, a range of restricted frequencies, a minimum number of different hopping frequencies within the allowable frequencies, the maximum output power of a transmitter and a requirement related to equal use of the hopping frequencies.
  • security monitoring systems are used to monitor a variety of facilities and to sense the presence of unwanted intruders. Many such security systems are connected to a central control unit and monitored by an operator who can alert the appropriate emergency services in the event of an unwanted intruder.
  • a home monitoring security system includes a combination of sensing devices and alarm devices and some also include cameras. To achieve the maximum monitoring coverage, these devices are distributed throughout the interior of the facility.
  • Security systems that employ cameras are advantageous in that they are able to record activity associated with a suspected breach of the facility and also can be used by a monitoring station to prevent false alarms. In some instances, however, the cameras record the regular activities of the facilities' residents and/or employees. The cameras also record activities that are falsely perceived to be security breaches such as pet behaviors and authorized users that have been accidentally locked out.
  • US 2005/0162268 discloses a video surveillance system, wherein at least one sensor condition defines an alarm state for each camera.
  • the present invention is directed to the above and related types of integrated security systems.
  • the present invention provides an integrated security arrangement as claimed in claim 1.
  • the present invention also provides an integrated security arrangement as claimed in claim 11.
  • an integrated security arrangement includes an intrusion sensor to detect an intrusion, a plurality of motion sensors, and a plurality of image-capture devices. Each of the image-capture devices is responsive to a respective one of the motion sensors and when the image-capture devices are enabled they capture images of respective target areas in response to movement in the respective target areas as indicated by the respective motion sensors.
  • the integrated security arrangement also includes a mapping database that contains data used to associate one or more of the plurality of image-capture devices with the intrusion sensor. The mapping database is configurable by a user.
  • the integrated security arrangement further includes a control unit that enables one or more of the plurality of image-capture devices in response to the intrusion sensor detecting an intrusion. The control unit determines whether to enable one or more of the image-capture devices based upon data in the mapping database.
  • the present invention is believed to be applicable to a variety of different approaches and arrangements for providing security services.
  • the invention has been found to be particularly advantageous for addressing security monitoring needs in a residence or private-office environment.
  • a security system utilizes cameras to detect and identify intruders.
  • the system includes an integrated camera/motion detector that is responsive to intrusion sensors and other types of sensors/alarms (e.g., a smoke detector, a carbon monoxide detector, a gas detector, or a panic button).
  • intrusion sensors e.g., a smoke detector, a carbon monoxide detector, a gas detector, or a panic button.
  • sensors/alarms e.g., a smoke detector, a carbon monoxide detector, a gas detector, or a panic button.
  • the integrated camera/motion detector being responsive to intrusion detection; however, the discussion is equally applicable to the integrated camera/motion detector being responsive to other types of sensors and alarms as well.
  • the camera's smart-behavior results in reduced power consumption and mitigates privacy concerns on various levels.
  • a system user sets up zones with at least one intrusion sensor (e.g., door/window contacts, glass-break detectors, hyper frequency radar detector, or an infrared barrier) for each zone around the perimeter of a facility and sets up corresponding camera/motion detectors in the interior of the facility.
  • the intrusion sensors are activated (armed) by a system user, using, e.g., a keypad on a security panel, a remote control keyfob, a phone call using DTMF, a personal computer or a remote server. This allows for a complete activation of the system when the system user leaves the facility as well as a partial perimeter activation of the facility when the system user (or other authorized person) is present.
  • the system user enters a code (e.g., using a keypad on a security panel) to identify the desired mode of system operation.
  • the system user enters a system access code and then selects that desired mode of operation from a display.
  • the arrangement includes an intrusion sensor to sense an intrusion at a target area of a facility, a second sensor to sense movement, an image-capture device, and a base unit.
  • the image-capture device captures images in response to an intrusion indication from the intrusion sensor and in response to a movement indication from the second sensor.
  • the base unit integrates a direction of view of the second sensor and of the image-capture device, thereby directing the second sensor to sense in the target area in which the images are captured by the image-capture device.
  • FIG. 1 depicts a building-security system according to an example embodiment of the present invention.
  • FIG. 1 includes building 100, control panel 102, and peripheral devices 104-110.
  • the security system is implemented in such a manner so as to reduce the power consumption of one or more of the control panel and peripheral devices as related to the wireless communications between the devices.
  • the devices use multiple frequencies (channels) as well as communication intervals.
  • the devices are able to reduce the power consumption by utilizing information regarding a specific frequency from the multiple frequencies used and the communication interval. For example, if the transmitting devices modify their transmissions based upon the information, a receiving device may reduce the power consumption by decreasing the time the receiving device is listening for a transmission from another device.
  • the system lends itself to implementing bi-directional communications between the devices, which typically require more power consumption than unidirectional communications.
  • the jagged lines and ellipses found between control panel 102 and the peripheral devices represent wireless communications between the control panel and the peripheral devices.
  • the wireless communications may be implemented using suitable frequencies. For instance, wireless communications frequencies in industrial, scientific and medical (ISM) radio bands (900Mhz, 2.4Ghz and 5.8Ghz) have been found to be suitable for security systems; however, alternate frequencies may be implemented in accordance with the particulars of the system or its intended implementation.
  • ISM industrial, scientific and medical
  • peripheral devices and the control panel are implemented using one or more of electric circuit arrangements, processors, memory elements, software code, programmable logic devices, input/output interfaces or combinations thereof.
  • Building 100 represents a facility for which the building-security system is implemented. Common implementations of building 100 include, but are not limited to, residential homes, retail stores, office buildings, government buildings, museums and other facilities. Typically, the security system will monitor several locations within building 100. Accordingly, FIG. 1 depicts various peripheral devices throughout the building.
  • Peripheral communications devices 104-110 may take the form of a variety of different devices, a few of which are depicted in FIG. 1 .
  • device 104 depicts a window sensor that may, among other things, detect when the window has been opened or otherwise compromised;
  • device 106 depicts a camera for video capture;
  • device 108 depicts an alarm;
  • device 110 depicts a mobile peripheral, such as a key fob for interfacing with the control panel or another peripheral.
  • Other example sensors include but are not limited to fire alarms, carbon dioxide sensors and panic buttons. These peripheral devices communicate with control panel 102 using wireless communications.
  • Block 112 depicts several elements that may be implemented in the peripheral devices, including a transceiver block, a message protocol block, a synchronization block and a transmit (Tx) anticipation block.
  • a peripheral device wirelessly transmits a signal using the transceiver block.
  • the peripheral device uses information regarding a transmission period and the listening channel of the control panel in the transmission process.
  • the peripheral devices transmit building-security information to the control panel.
  • device 106 might transmit video images or device-status information to the control panel, while device 104 might transmit information relating to the window's sensor.
  • FIG. 1 depicts control panel 102 as including a transceiver block, a message protocol block, a synchronization block and a transmit (Tx) anticipation block.
  • the transceiver block is used for receiving signals from one of the peripheral devices as a function of the communication intervals and the frequency the control panel uses to listen for transmissions.
  • the listening frequency is one of several potential frequencies available for communication between the peripheral devices and the control panel.
  • the system may use a number of contiguous frequency slots (channels) within a suitable frequency band.
  • One example of such a use includes 25 or more channels within the ISM frequency band from 902-928 MHz. Numerous other combinations of channels and frequency bands are possible using the present invention.
  • the control panel and peripherals are implemented using a similar set of elements as depicted by blocks 102 and 112; however, various components may be implemented differently.
  • the synchronization block can be implemented differently in the control panel versus the peripheral devices where the control panel provides synchronization information to each of the peripherals and the peripherals must use the synchronization information to maintain synchronization using a local clock.
  • the peripherals would compare the synchronization information with the local clock in order to compensate for any difference between the peripherals' time frames and the control panel's time frame.
  • the synchronization information can take the form of a time index, such as a counter value, a current time of day or any other time based data which the peripheral can use as a reference for synchronization.
  • the time index can be a reference within each message transmitted.
  • the peripheral device can compare when the message was received to when the message was expected.
  • the peripheral device may also be configured to adjust the local clock using a compensation for a timing error. For instance, if the peripheral clock appears to be running slower than the control panel, the peripheral can compensate by increasing the clock frequency or using a counter to compensate for the differences between clocks.
  • control panel and the peripheral blocks are depicted as having a transceiver; however, the system may be implemented using variations of receivers and transmitters.
  • a peripheral may be implemented with only a transmitter.
  • a peripheral may be implemented with only a receiver.
  • Other implementations allow for one or more of the control panels and peripherals to have both a transmitter and receiver (transceiver).
  • transceiver is used herein to describe a receiver, transmitter or both a receiver and transmitter.
  • One embodiment of the present invention reduces the power of one of the devices as a function of the listening channel and a communications period.
  • the system decreases the length of time that a receiver is active by using the communications period and listening channel to reduce the window of time necessary to receive the start of a transmission.
  • various methods of power reduction are employed, such as removing power from the receiving devices or reducing or stopping selected functions (e.g., amplification or processing).
  • the synchronization can further reduce the active time of the transmitter because, for example, the transmitter may limit the transmission times relative to the times for which the receiver is active. Such a reduction can be accomplished because, for example, in many systems the transmission time cannot be shorter than the Rx activation period of the receiver without knowledge of when the Rx activation occurs; however, synchronization can reduce the transmission times to less than the Rx activation period of the receiver.
  • the control panel sends periodic synchronization messages to the peripheral devices.
  • a peripheral device that determines it has lost synchronization with the control panel can increase the active time of the receiver to compensate for the loss in synchronization. In the event that the peripheral device is no longer receiving synchronization messages, the device can increase the active receive time to ensure that a transmission from the control panel will be received.
  • the peripheral device can increase the activation time based upon an expected accuracy of the local tracking (e . g ., local clock) of the control panel time-base. For instance, where the expected accuracy of the local tracking is relatively high, the peripheral device increases the activation time only upon the loss of several synchronization messages.
  • Some devices such as a keyfob or other handheld device (110) are portable and are often removed from the wireless communication range of the rest of the system or may cease to receive or transmit information in response to a period of inactivity. Thus, the portable devices often lose synchronization during the time they are unable to communicate with the control panel. Accordingly, such portable devices frequently increase the activation time to compensate for the lack of synchronization between the portable devices and the control panel. The frequent increase in activation time often leads to a high rate of power consumption. To compensate, portable devices can be implemented to shut down transmission monitoring efforts until an external action occurs, such as a button being pressed.
  • the messages sent by the control panel are received by multiple peripheral devices simultaneously. Where the message is not intended for all the peripherals, the message can include information that indicates for which peripheral the message is intended. The message can also be associated with a channel that the control panel uses for an acknowledge message from the peripheral.

  • the base unit 35 can receive the intrusion sensor input 10 via communications interface 15. The sensor input 10 can therefore inform either the base unit 35 or the control panel 45 to arm the motion sensor 20 and/or activate the camera 25.
  • the motion sensor 20 When unarmed, the motion sensor 20 will not be able to activate camera 25 but may still detect motion.

Upon receipt of the intrusion signal, the motion sensor is armed and the integrated camera is set to a "ready" mode without initiating recording. The motion detector remains armed and when motion is detected, the integrated motion sensor/camera is again triggered. Once motion is detected, the camera turns "on” and captures images of the source of the motion. The video images are sent to a central control panel for further evaluation.

  • Further evaluation may include determining (manually or automatically using, e.g., machine visions) whether the source of the motion is human, an animal such as a pet, or another moving object. If the source is determined to be human, further evaluation may reveal whether any identifying images were captured, whether the human is an intruder or an inhabitant of the facility, and face recognition may be used to identify a previously unknown person intruding on the facility.
  • the home entry intrusion sensor corresponds to a delayed-respqnse motion sensor such that the transmission of the motion indication is delayed to accommodate a security system control keypad located near the entrance.
  • the motion indication is not delayed when motion is detected.
  • the system recognizes that motion sensed in the nearby room (e.g., person setting grocery bags down in the kitchen) following a delayed sensing of motion in the entry zone is likely an authorized user and an alarm will not sound for a predetermined length of time. If the system is not deactivated or reset before the predetermined length of time expires, the alarm will sound.
  • the number of nearby zones configured with such a relationship with the delayed motion indication in the entry zone should be limited to ensure that an actual intruder is not provided enough time to traverse the premises without being detected.

  • sensors can be added or replaced at later dates.
  • camera 202 can operate in different modes that may or may not be responsive to sensors 204. For example, one mode may disable camera 202 completely, while another mode may enable camera 202. One such mode would include control block 206 enabling cameras 202 in response to one or more selected sensors 204. In one embodiment of the present invention, different modes may have different sensors mapped to camera 202. For instance, one mode may have a door sensor mapped to camera 202, while another mode may have both a door sensor and a motion sensor mapped to camera 202 ( e.g., for when there should be no authorized occupant in the area). The system can be programmed such that a different code is used to identify each of these modes of operation.
  • the system user enters one of the codes (e.g., on a security system control keypad) to select the desired mode of operation.
  • the system user enters a security access code and then selects from one of the programmed modes of system operation that are identified on a display screen ( e.g., by selecting a corresponding icon on a touch screen or by entering a number identifying one of the modes).
  • the system user enters a code for each mode of operation. This can be useful for allowing different levels of access/mode settings for different users. For instance, a child, friend or relative could be given only certain codes. This is particularly useful for controlling access to configuration settings or preventing access during restricted time periods, such as late at night.
  • one of the codes may correspond to a sequence of image captures from various cameras.
  • a user of the system can initiate a sequence of camera shots to view different areas of the facility. This can be particularly useful for assuring a user that there are no intruders or for monitoring the status of an occupant ( e.g., a small child or otherwise vulnerable person) and the house in general ( e.g., to check for fire or damage due to natural disasters).
  • the camera can be enabled in various ways.
  • enabling of the camera includes enabling the camera arrangements discussed in connection with figures 1-3 .
  • the motion detector of the camera arrangement is enabled. If the motion detector senses motion, the camera can then be enabled to capture pictures of potential intruders.
  • the camera can also be configured to immediately capture pictures ( e.g., regardless of the motion detector) in response to the detection of a potential intruder. This can be particularly useful for sensors that do not necessarily correspond to an intruder (e.g., fire alarm) and for high security modes that do not implement a delay or second level of motion detection.
  • the camera would capture images independent of motion detection by the motion sensor.
  • Another mode or setting could be used to distinguish between video capture (e.g., consecutive shots over a period of time capable of showing motion, such as those stored in an MPEG file) and still image capture (e.g., one or more individual images that can be stored using file formats such as JPEG) by the camera.
  • the system in response to a sensor and a selected mode, can be configured to 1) capture images after detecting motion in the field of view, 2) immediately capture video, and 3) immediately capture a still image.
  • FIG. 3 shows a block diagram of a security system for mapping a plurality of cameras to a sensor, according to an example embodiment of the present invention.
  • sensor 302 and cameras 304 i.e., camera(1) to camera(N)
  • control block 306 In response to input from sensor 302, one or more of cameras 304 can be enabled.
  • the control block 306 can implement the desired correspondence between cameras 304 to sensor 302 using mapping database or lookup table. This can be advantageous where the cameras provide different angles of view and/or different fields of view. For instance, in response to window sensor, several cameras can be enabled, allowing for security monitoring stations to view the entire room, and also to have a better chance of identifying a potential intruder.
  • multiple cameras can be selectively linked to multiple sensors. For instance, all cameras and sensors within a room can be linked together. Accordingly, the mapping of both FIG. 2 and FIG. 3 can be used in conjunction with each other.
  • FIG. 4 shows an example mapping or lookup table, according to an example embodiment of the present invention.
  • the data contained in the mapping table can be stored in a suitable memory device, such as flash, random-access-memories, hard drives and the like.
  • a suitable memory device such as flash, random-access-memories, hard drives and the like.

  • Column 402 contains camera-1 to camera-N. It should be noted that FIG. 4 and the relevant discussion make reference to camera-1 to camera-N. As discussed herein, such cameras may include an integrated motion detector, and thus, identification information as to whether the camera device includes such an integrated motion detector may also be stored in the mapping or lookup table.
  • Column 404 contains sensors that are configured to enable the camera arrangement in the corresponding row. For instance, sensors A, B and C would enable camera 1, while sensors X, Y and Z would enable camera 2. In this manner a user of the system provides information as to the desired associations between sensors and cameras resulting in a corresponding change in the data in the mapping table. For example, a graphical user interface can be presented to a user through a software application running on a processor.
  • the processor is a general purpose computer, such as a personal computer or personal digital assistant, that can interface with the control device of the security system using, for example a universal-serial-bus (USB), Ethernet or similar interface.
  • the processor is part of the control device.
  • Column 406 contains additional information regarding relationships between sensors and cameras.
  • column 406 represents sensors that enable the corresponding camera when the security system is in a particular mode (i.e., a different mode than column 404 would be associated with). This is useful to distinguish between situations where the occupants are awake from when they are sleeping, windows that are opened from the inside from windows that are opened from the outside, situations where the occupants are on vacation from when they are not, and the like.
  • column 406 represents sensors that need to be triggered prior to sensors in column 404 activating a camera in column 402.
  • the sensors can be linked to each other, thereby requiring a succession of sensors to be triggered prior to activation of a mapped camera.
  • column 406 represents sensors that are only enabled after a certain delay. This can be particularly useful for enabling sensors that are in the likely path of an intruder. For instance, the camera in a bedroom may be enabled after a window sensor in the bedroom is triggered. After a delay sufficient to allow an intruder to traverse the room, a sensor from column 406 and corresponding to an adjoining room can be enabled.
  • Column 408 represents additional data used to supplement the mapping functions.
  • column 408 may contain information relating to cameras that are only enabled after a certain delay. This can be particularly useful for enabling cameras that are in the likely path of an intruder. For instance, the camera in a bedroom may be enabled after a window sensor in the bedroom is triggered. After a given delay ( e.g., sufficient to allow an intruder to traverse the room) a camera in an adjoining room can be enabled.
  • column 408 may contain data that contains delay values for enabling the cameras or sensor of column 404 and 406.
  • the data in column 408 can be used to denote one or more security modes for which the sensors and cameras stored in the respective mapping table columns are enabled or disabled.
  • a combination of sensor events and the details of the sensor events can be selected to further define enabling events for various cameras.
  • combinational events can be used to determine details, such as whether a series of sensor events represent a person leaving or entering an area. More specifically, the order of sensor events and the absence of certain sensor events can be used to determine the direction a person is traveling, the number of people present and other security factors.
  • the system can be configured to avoid unnecessary video capture of normal occurrences, such as the exit of an authorized person from a secured area, while still capturing abnormal occurrences, such as the entrance of a person to the secured area.
  • mapping table e.g., similar to columns 406 and 408 are possible and only limited by practical considerations, such as complexity and storage space.
  • FIG. 5 shows a flow diagram for logic for implementing a process to enable security cameras in response to mapped sensors, according to an example embodiment of the present invention.
  • Block 502 represents a decision as to whether a sensor has been triggered. The process waits at block 502 for a sensor to be triggered. If a sensor is triggered, the process proceeds to block 504. Block 504 determines whether the sensor is mapped to a camera. If no camera is mapped to the sensor, the process returns to block 502 and waits for another sensor to be triggered. If a camera is mapped to the sensor, the process proceeds to block 506.
  • Block 506 represents potential enable logic.
  • the enable logic depicted by block 506 need not be implemented. In such a case, the process proceeds directly to block 508. In other instances, various determinations, delays and other functions can be carried out at block 506.
  • information stored in a mapping table is used to implement the enabling logic. As discussed herein, such information may represent different logic for different modes, delays before enabling and the like.
  • the logic may determine that no camera should be enabled and the process proceeds to block 510. One such instance is where the security system is in a mode for which the linked camera is not to be enabled. In another instance, the logic may enable other sensors prior to enabling the camera. After determining that the camera should be enabled the process proceeds to block 508 to enable the camera.
  • Block 512 is a logic block similar to block 506, where the process can branch to blocks 510 or 514.
  • Block 514 enables the corresponding camera and returns to block 510 to determine if additional cameras are mapped to the triggered sensor. In this manner, a series of cameras can be enabled in response to one or more triggered sensors. This is particularly useful for enabling cameras along a likely path of an intruder.
  • the various components of such a process can be implemented using one or more general purpose processors configured with appropriate software, one or more custom processors, programmable logic devices, analog/digital circuits, integrated circuit devices and combinations thereof.
  • FIG. 6 shows a flow diagram for logic used to enable cameras for a security system, according to an example embodiment of the present invention.

  • the process begins at block 602 where it proceeds to block 604.
  • Block 604 can implement a delay before enabling any cameras. If no delay is require, the delay step can be skipped. In one instance, the delay can be a fixed delay for each camera. In another instance, the delay can be a function of data stored in the mapping table along with other variables, such as the current mode of the security system. After the delay, if any, is implemented, the process proceeds to block 606.
