Detection system using personal communication device with response

[0001] This application claims the benefit under 35 U.S.C. 119(e) of U.S. provisional patent application ser. No. 60/098,270, filed Aug. 28, 1998, which is incorporated by reference in its entirety.

[0002] The present invention relates generally to detection systems and in particular to the use of a personal communication device with response in central station monitoring of security systems.

[0003] In the security alarm industry, detection devices at a premise detect various conditions at the premise. These conditions may indicate fire, burglary, medical, environmental or other conditions that may exist. The security system then transmits the information to a central response center (central station) that then coordinates the response activities of others back to the premise. However, most of the alarms transmitted are false, which results in the false dispatching of police, fire, and medical teams on a large scale. This creates numerous problems for public response agencies, endangers public safety, and increases costs to consumers and industry providers.

[0004] Various industry studies have determined that the source of these false dispatches are caused by the user of the system more than 75% of the timeuser error. Much of the user error occurs when the user is actively operating their system; that is, is turning the system on or off. When turning the system on such users are generally exiting the premise and are activating the system to protect the premise in their absence. Likewise, if the user is turning the system off this generally occurs when the user is returning to the premise. As a result, much of the user errors occur when users are coming or going from their premise.

[0005] In order to mitigate the number of false dispatches, the industry standard process has been to verify the alarm by attempting to contact the alarm users by telephone at the premise before dispatching a response agency. In such an instance, if the users are arriving at the premise, there is a chance of reaching them. However, most of the time, the users are unavailable because (a) they have just exited the premise(which accounts for about 50% of the occurrences) or (b) the telephone line to the premise is busy(some additional percent of the occurrences). When the user is unavailable, then the emergency agency, usually a police department, is dispatched to the premise.

[0006] False alarms are such a wide scale problem that many police departments are considering a no-response policy to electronic security systems, and indeed, some police departments in major cities have already implemented such a policy. Other departments are charging for response and many cities have instituted fines for multiple false alarms. If this trend continues, security alarm systems will become more expensive (through the use of private guard response or large fines) which will reduce the number of buyers who can afford or are willing to pay the costs that might be associated with these security systems. This will significantly impact the industry in a negative way and would be unfortunate to the public because security systems do reduce risk of loss and add safety to the persons they protect; not to mention that many thieves have been captured because of these systems.

[0007] What is needed in the art is a system to reduce the number of false dispatches so that police departments do not continue to take action against the industry and the owners of security systems. The system should be easy to use and should provide a user with the ability to cancel false alarms quickly.

[0008] The present system provides notification to users of a security system of a detected alarm condition. In one embodiment, this notification is performed simultaneously or nearly simultaneously with the central station. In one embodiment, the notification is performed using a wide scale wireless system so that the users can be notified regardless of their current location.

[0009] Such a system solves many of the previously stated problems and several others not mentioned herein. In one embodiment, the user is signaled using a wireless system, so if the user is leaving the premise, and perhaps at a significant distance, the user will still be notified. In one embodiment, the system connects the users of the security system directly to the central station system so that the alarm can be immediately verified or canceled with the central station. In the embodiment where the connection is wireless, the user or users may be in any location within the range of the wireless network. If the central station receives a cancellation of the alarm they can avoid dispatching the emergency agency or perhaps recall them if the dispatch has occurred.

[0010] In one embodiment the system provides a dynamic response process that is adjusted in real time or nearly instantaneously by the users of the system. That is to say, more than half of all false alarms may be canceled and more than half of all false dispatches can probably be avoided.

[0011] In one embodiment, the system provides nearly simultaneous and wireless connection of electromechanical data from a security or other detection system, remote human intervention (usually the users of the detection system), and the response centers to provide direction to a response effort. One aspect of this design is that the users of the detection system participate in directing the response effort indicated by various alarms from a security or other detection system.

[0012] Due to cost, power requirements, and relative design sizes, one embodiment of the system incorporates Narrowband PCS systems, otherwise known as 2-Way paging. Other embodiments include, but are not limited to, PCS, cellular, cellemetry and other broad scale wireless networks. Other embodiments incorporate combinations of these networks.

[0013] This summary is intended to provide a brief overview of some of the embodiments of the present system and is not intended in an exclusive or exhaustive sense, and the scope of the invention is to be determined by the attached claims and their equivalents.

The embodiments provided herein are not intended in an exclusive or limited sense, and variations may exist in organization, dimension, hardware, software, mechanical design and configuration without departing from the claimed invention, the scope of which is provided by the attached claims and equivalents thereof.

[0019] The present detection system provides many benefits, including, but not limited to, reduction of false alarms and false dispatches. The present detection system provides a user with the ability to cancel false alarms quickly and is straightforward to use. Many other benefits will be appreciated by those skilled in the art upon reading and understanding the present description. Furthermore, U.S. provisional patent application ser. No. 60/098,270 filed Aug. 28, 1998 is incorporated by reference in its entirety.

[0020] The present system provides notification to users of a security system of a detected alarm condition. In one embodiment, this notification is performed simultaneously or nearly simultaneously with the central station. In one embodiment, the notification is performed using a wide scale wireless system so that the users can be notified regardless of their current location.

[0021] In one embodiment, the user is signaled using a wireless system, so if the user is leaving the premise, and perhaps at a significant distance, the user will still be notified. In one embodiment, the system connects the users of the security system directly to the central station system so that the alarm can be immediately verified or canceled with the central station. In the embodiment where the connection is wireless, the user or users may be in any location within the range of the wireless network. If the central station receives a cancellation of the alarm they can avoid dispatching the emergency agency or perhaps recall them if the dispatch has occurred.

[0022] In one embodiment the system provides a dynamic response process that is adjusted in real time or nearly instantaneously by the users of the system. That is to say, more than half of all false alarms may be canceled and more than half of all false dispatches can probably be avoided.

[0023] In one embodiment, the system provides nearly simultaneous and wireless connection of electromechanical data from a security or other detection system, remote human intervention (usually the users of the detection system), and the response centers to provide direction to a response effort. One aspect of this design is that the users of the detection system participate in directing the response effort indicated by various alarms from a security or other detection system.

[0024] Due to cost, power requirements, and relative design sizes, one embodiment of the system incorporates Narrowband PCS systems, otherwise known as 2-Way paging. Other embodiments include, but are not limited to, PCS, cellular, cellemetry and other broad scale wireless networks. Other embodiments incorporate combinations of these networks.

[0025] Capcodes

[0026] In one embodiment using NPCS (Narrowband PCS) as the wireless transmission method, pager capcodes identify the individual user and the detection system that is transmitting the message. Capcodes are the addresses used to identify individual addressesthere is a unique capcode for each pager or common pager address, and common addressingpagers can hold more than one capcode for broadcast messaging. For example, capcode 978654903 may uniquely indicate Joe Smith's pager while another capcode may also reside on Joe Smith's pager for broadcast receipt of the news or weather. In one embodiment one or more capcodes may be used to uniquely identify one or more central stations.

[0027] Communication Paths

[0028] FIG. 1 shows one embodiment of the present detection system in which an alarm system 10 provides a signal to a central station 20. In this embodiment, the users 30 are notified of the alarm condition via a wireless means in order to provide the highest assurance of contact. Otherwise by using a standard land line telephone, it may not be possible to find the user. This wireless system is depicted as Path A in FIG. 1. In this embodiment, the central station 20 receives its verification information back from the user 30 having personal communication device 40 via wireless so that notification comes rapidly from wherever the user is located, otherwise the dispatch process will continue without an opportunity for intervention from the users 30. This is depicted as Path C in FIG. 1.

[0029] If Path A is selected instead of Path D, then in one embodiment a method of transmitting Path B is by a wireless technology matching Path A. This allows for the messaging to arrive at similar times at both the remote users 30 and the central station 20. As a result, the dispatch process has a good chance of starting in a synchronized fashion for both the central station 20 and the users 30. This will lead to a better coordinated effort.

[0030] In one embodiment, the personal communication device 40 is a two-way pager. In one embodiment, the personal communication device 40 is a cellular phone. Other personal communication devices 40 may be used without departing from the present system.

[0031] Rapid Data Transmission

[0032] It is important that the data is received rapidly both to enhance protection and to help to provide rapid verification in order to cancel alarms. The transmission of data in this embodiment is done in a rapid burst method. One reason for this is as follows: As available in NPCS transmissions, for example with FLEX 25, REFLEX 25, or REFLEX 50 (communications protocols by MOTOROLA CORPORATION)one of the protocols currently available for NPCS servicesthere is a short message availability (11 bit) that allows for very rapid transmission. In cellular there is a technology called cellemetry that accomplishes a similar function. This short and rapid messaging is a feature of many large scale wireless networks. The short message is typically available to be sent immediately and rapidly. For example, in FLEX 25, longer messages require time to set up transmission frames. By using a short form transmission, as much as 20 seconds or more may be saved in the transmission time requirement. This delay is of serious consequence because in at least one applicationthe security industrylife and property may be in peril. In addition, delays make it difficult to coordinate the rapidly proceeding dispatch between the central station 20 and the users 30. However, the short message has constraints of its own: it is a short message. Therefore, in one embodiment using FLEX 25, the message is encoded. One solution for encoding is presented later.

[0033] Hence, in this embodiment a short predetermined digitally encoded message is transmitted from the alarm system 10 to the central station 20 and to the personal communication device 40 carried by remote users 30. In one embodiment, at the central station 20 a look up table is employed to decode the message. Additionally, in one embodiment, a look up table is employed by the remote user device 40 to decode the message.

[0034] Message Decoding in the Network

[0035] Usually transmission networks are designed to receive a message and transport it to a destination. The network doesn't read the message or act on it except to read an address and send it to the destination. However, as networks become imbued with enhanced computing capability, they can read more of the message and process far beyond mere transport.

[0036] Therefore, as an alternative embodiment, the look up table can reside in the network and the message can be decoded by the network before it is delivered to any destination. This is a good way for delivering a message to the users 30. The encoded short form message is decoded in the network and a user 30 is delivered an English (or other language) language message according to the interpretation or look up table.

[0037] The effect is that an encoded short form message that looks like 001010000111 can be decoded in the network and read out, for example, Burglary Area 4 on a device 40, such as a pager. The same numeric message can be decoded after receipt in a more sophisticated user device 40 or after receipt at the central station 20.

[0038] Communication with the User

[0039] One embodiment of this design uses a single two way wireless device 40 carried by the users 30 instead of one device to receive the message and another to transmit the verification information to the central station 20. This saves cost and simplifies design. However, two separate devices 40 could be used.

[0040] The notification of the remote users 30 can be accomplished simultaneously with the central station 20 or instantly relayed by the central station 20 or any other relay point. Either process has an identical effect of creating nearly simultaneous notification of an alarm condition to the users 30 and the central station 20.

[0041] Information relative to verification, dispatch cancellation or other instructions, sent from the users to the central station 20 can be received as data that is automatically integrated into the automation system at the central station 20.

[0042] However, in other embodiments, manual processing of the data or other messages can be done.

[0043] Because the user information comes from a different device (different capcode when using NPCS) than the security alarm report from the users' security system, the information must be integrated in the central station automation system as related information from discrete sources. Existing methods used for integrating multiple security systems reporting from a single premise can be used to integrate these multiple sources of information. These methods vary between various automation systems, but the effective result is the same and can be used to a new benefit.

[0044] Again, in one embodiment, the transmission of data can be done in a rapid burst method. In this process, a short predetermined digitally encoded message is transmitted to the central station 20 from the user device 40.

[0045] Alternatively, longer messages can be employed, but they may take longer to be received.

[0046] At the central station 20 a look up table is employed to decode the message. As before, alternatively, the look up table can reside in the network and the message can be decoded by the network before it is delivered to any destination. The central station 20 can receive instructions not to dispatch an emergency agency or other instructions regarding a pending or processing dispatch.

[0047] In the event that NPCS is the selected wireless transmission method, a standard two way pager using response paging can be used as the response device 40 carried by the user 30 to provide direction to the central station 20, in one embodiment.

[0048] In this design option a response message can either be presaved on the two way pager or can be transmitted to the pager. Since time is important, a presaved response message is a fast solution since it does not require any additional transmission time.

[0049] Other embodiments incorporating custom designed devices and devices using other wireless technologies can also be used to accomplish the same effect.

[0050] Encoding

[0051] In one embodiment, encoding is a straightforward process. The following encoding example is offered for the use with NPCS FLEX 25 or REFLEX 25 two way pager wireless services.

[0052] In Flex 25 an 11 bit message (an 11 bit message is eleven zeros or ones) is available for a short form transmission. This message is then split into registry sections for the purpose of sending a message. The table in FIG. 4 describes sample registers and their potential purpose.

[0053] As a result a message like 001/0111/0101 (slashes indicate breaks in the register of the look up table and are not transmitted) can be interpreted to mean: send a message to Joe Smith's pager capcode 957843756 reading Fire area 5 and send a message 001/0111/0101 to Central Station A and send 001/0111/0101 to Central Station B if Central Station A is not receiving.

[0054] The above register size, order, and meaning can be changed to meet the needs of individual network designs. However, the purpose and use remains unchanged. Similar encoding registers can be used in any wireless transmission short form format.

[0055] One embodiment of the present system is provided in FIG. 2. The detection system generates codes, data, or other type of input 210. In one embodiment, a look up table in the detection system or transmission device selects destination codes and encodes short messages 220. The encoded short message is burst into the network 230. The network decodes destination codes with look up table and passes messages 240. If the destination code is a user code, then the message is transmitted via a long range wireless network 250. The message is decoded by the network for display on a pager or decoded in the user device 260. If the destination code indicates a central station, then the message is transmitted via long range wireless network 270 and the encoded message is received and decoded at the central station 280.

[0056] In FIG. 3, transmissions from a remote user to a central station are shown. In one embodiment, a presaved message is selected or entered using verification information 310 and optionally it is converted to an encoded burst transmission 320. The information is transmitted via a long range wireless network 330 and decoded at the central station destination 340.
