SECURITY SYSTEM FOR IDENTIFYING DISTURBANCES IN A BUILDING

FIELD OF THE INVENTION

The present invention relates to a security system and, more particularly, to a security system capable of recording and transmitting video and audio of a disturbance or emergency situation in a room in a building to nearby rooms to provide occupants of those rooms information regarding the situation to allow them to take appropriate action.

BACKGROUND OF THE INVENTION

School shootings have always been a major concern in this country and numerous measures have been adopted to reduce their occurrences and harm. Legislations have been enacted to restrict access to firearms and security systems have been installed to record emergency situations and notify safety authorities. Given the increased number of shootings and death toll in the recent years, however, it appears that these measures are inadequate. Individuals can still purchase a gun from the black market or steal it from a legal owner, and current security systems are not capable of providing live information of an emergency situation directly to those nearby so that they can evacuate promptly and safely.

For example, U.S. Pat. No. 8,305,211 to Morris et al. (“Morris”) discloses a surveillance system comprising a security installation having video cameras and door locks securing an institutional building and a peer interface connected to a plurality of peer installations, each of which is connected to a corresponding aid provider such as a police station, fire department, or hospital. Upon determination of an exigent situation, the peer interface of the security installation selects the proper peer installation that allows the corresponding aid provider to watch the live exigent situation and provide assistance, such as making announcements for directing existing crowds away from the exigent situation or locking doors to prevent perpetrators from causing harm. As such, this system is deficient in that it requires awaiting safety instructions from the aid provider as the crowds do not have firsthand information of the exigent situation and they would not be able to execute self-help or take actions they deem appropriate. Moreover, broadcasting safety instructions in the place where both the assailant and the crowds are located is not practical as the assailant may follow the instructions to the area where the crowds congregate or exit to cause more harm.

In another example, U.S. Pat. No. 7,116,224 to Mickler (“Mickler”) discloses an alarm ready portable case for securing a firearm that may be utilized in conjunction with a

CA 029317«? 2016-05-2«

WO 2015/088722 PCT/US2014/066388 pre-existing security system. With authorized access, a person can remove the gun in the case and use it as a defensive weapon. If unauthorized access is determined, the case would sound an alarm. Mickler, like Morris, does not have the ability to provide firsthand information of an exigent situation. U.S. Pat. No. 5,416,272 to Torii (“Torii”) discloses a similar firearm case but lacks the same ability.

In yet another example, U.S. Patent No. 6,965,541 to Lapin et al. (“Lapin”) discloses a gun shot digital imaging system comprising an acoustic sensor for detecting a gun shot or explosion and a camera for recording images of the area of the gun shot or explosion. When a gun shot or explosion is detected by the acoustic sensor, the camera is slew toward the area of the gun shot or explosion to record images of that area. While this system can record images of an emergency situation, it is not designed to transmit the recorded emergency images to those nearby to provide live information of the situation. In addition, this system cannot be used to record an emergency situation that does not involve either a gun shot or explosion.

Accordingly, there remains a need for an improved security system that overcomes the deficiencies of the prior art and that provides real time advanced warnings to individuals located nearby an emergency situation.

SUMMARY OF THE INVENTION

The invention now provides a security system for identifying a disturbance in a room of building. This system comprises a camera and monitor in each room of the building that is accessible to individuals, with the camera being positioned and located to record and transmit viewing of a substantial portion or all of the room when the camera is activated. The camera is able to record both sights and sounds occurring in the room while each monitor is engageable to receive transmissions from one or more cameras of other rooms. The system includes a storage compartment for a weapon located in at least one of the rooms. The storage compartment is associated with at least two activation mechanisms, a first one associated with activation of the system for a non-emergency situation and a second one associated with activation of the system for an emergency situation.

The first activation mechanism is designed, positioned and configured to activate the camera in a room experiencing a non-emergency disturbance so that events occurring in the room during the disturbance can be recorded, while the second activation mechanism is designed, positioned and configured to, sequentially or simultaneously, activate the camera,

-2CA 02931767 2016-05-26

WO 2015/088722 PCT/US2014/066388 open the storage compartment to provide access to the weapon therein and generate an alarm that indicates that an emergency situation exists in the room, with the camera allowing video and audio of the events in the room to be simultaneously recorded and transmitted to the monitors of at least adjacent or nearby rooms to provide occupants of those rooms information regarding the emergency situation. Advantageously, each room of the building includes a camera, monitor, storage compartment and first and second activation mechanisms.

The first and second activation mechanisms are generally mounted on the storage compartment for convenience. In an alternative embodiment, one of the first and second activation mechanisms, or both, may be mounted on a wireless remote. A convenient second activation mechanism may be a button, keypad, finger print sensor, smart card sensor or acoustic sensor in order to provide easy access to the storage compartment to quickly retrieve the weapon from it when necessary. The weapon is typically a handgun, stun gun, club or bat, tear gas or pepper spray. The acoustic sensor can be used to detect a gunshot, an explosion, a breaking window, or noise having a certain decibel level or frequency as this would indicate an emergency situation in the room. Also, a smoke or fire sensor may be associated with the storage compartment to independently monitor those situations an provide an alarms as necessary.

In operation, it is anticipated that access to the second activation mechanism is provided after the first activation mechanism is activated. This allows a person in the room, typically an authorized person such as a school teacher, to record events that start as a distraction or disturbance before escalating to an emergency situation. To assist in communicating the status of the situation in the room, the storage compartment may be provided with comprises communication capabilities that are typically located in or near the storage compartment and that are accessible after the first activation mechanism is activated.

It is preferred for the system to include additional cameras located in hallways, stairs, elevators, or doors providing access to the building to view those areas and transmit video and audio of activities thereby as further information to the individuals that are located near the disturbance or emergency situation. When an intruder is present or the situation escalates to areas outside of the room, these cameras can observe movement through the building. Typically, the additional cameras are activated when the second activation mechanism is activated. The additional cameras are preferably provided on a monitor that displays video and audio of the events occurring in the room where the disturbance is located and that

-3CA 029317«? 2016-05-2«

WO 2015/088722 PCT/US2014/066388 includes a microphone for recording sounds near the monitor. The video and audio of the camera in the room in which the emergency situation exists and the video and audio of the additional cameras or monitors in the hallways, stairs, elevators, or doors providing access to the building all can be transmitted to a security office to provide information of the situation and movement of the intruder or individuals through the building. The security office may be a principal’s office, a school security office or a police station or other remote security service.

The second activation mechanism also is designed to transmit information to lock down doors, stairwells or elevators nearby the room in which the emergency situation exits or in a section of the building nearby the room in which the emergency situation exits in an attempt to contain the emergency situation to the room or adjacent locations. This can be prevent an intruder from gaining access to other areas of the building and can help isolate the intruder to facilitate containment or capture by security personnel.

DETAILED DESCRIPTION OF THE INVENTION

Referring to Fig. 1, one embodiment of the security system 100 for identifying a disturbance in a building 150 is illustrated. Security system 100 comprises a camera 101 and monitor 102 installed in each room 104 and a storage compartment for a defensive instrument 103 installed in at least one or more of adjacent rooms 104 as well as in common area 105.

The camera 101 is typically a digital camera that is capable of recording both sights and sound. It is located and positioned so that the sights and sounds in a substantial portion or all portion of the room in which it is installed can be recorded when it is activated. The

-4disturbance in a school setting, for example, could be an unruly student or a fight between students that occurs in a classroom. When activated by the teacher, the camera will record the incident for possible future review to determine which students were unruly and deserving of discipline. In that type situation, the camera does not transmit the recording but simply maintains it for future use. The camera can include internal storage but it is more secure to have the camera transfer the collected images and sounds to a storage location.

The monitor 102 in the same room is operatively associated with each camera 101 of other rooms to receive video and audio transmissions from one or more cameras 101 of other rooms. The monitor 102 may be associated to each camera 101 of other rooms through wired or wireless connections. It is envisioned that the monitors are not activated unless an emergency situation is present, and this is to provide people in adjacent or nearby rooms with real time information regarding the emergency situation so that they can react appropriately. In some cases, the actions may be to move away from the situation to a more safe or secure location, or when a monitor in a security office is activated, to inform security personnel of exactly where to contain or counter the situation. The cameras mounted in hallways and directed at entry and exit passages, including the grounds around the building, can provide information of movement or travel of intruders or persons fleeing the emergency situation to help direct and control such movement or travel.

The storage compartment 103 stores a defensive instrument which may be accessed and used by an authorized person such as a teacher. To prevent unauthorized engagement or of the system or access to storage compartment, at least two activation mechanisms 106,107 are provided. The storage compartment 103 may be remotely associated or physically associated with the least two activation mechanisms 106,107. When remotely associated, the at least two activation mechanisms 106, 107 may be mounted at a location remote from the storage compartment 103 and be connected to the storage compartment 103 through a wired or wireless network. The at least two activation mechanisms 106,107 may also be mounted on a wireless remote control for use in each room 104. When physically associated, the at least two activation mechanisms 106,107 may be mounted directly on the storage compartment 103.

The at least two activation mechanisms 106,107 may be installed in more than one room or all of the rooms 104 and be associated with the storage compartment 103 in the manner described herein. Engagement of the system would typically be made by an authorized person and for that a security code would be provided to prevent inadvertent or

-5□ate Reçue/Date Received 2021-02-16 unauthorized engagement. While this is not entirely necessary for the first activation mechanism, it would almost be often required for the second activation mechanism. Otherwise, anyone would be able to access the storage compartment to withdraw the weapon from it. Weapons such as handguns, stun guns, tear gas or pepper spray are capable of causing harm and the security code would provide additional protection from unauthorized access to such weapons.

One of the at least two activation mechanisms 106, 107 in the room, or in the multiple rooms if more activation mechanisms are installed, is associated with non-emergency situations and is used only to activate the camera in the same room to record video and audio in the room. As noted, this activation mechanism would not transmit the recorded video and audio to the monitors 102 in other rooms. The other one of the at least two activation mechanisms 106,107 may be associated with an emergency situation and be used to activate the camera tn the same room to record video and audio in that room and to transmit the recorded video and audio to the monitors 102 in other rooms and to a security office 120.

The other one of the at least two activation mechanisms 106,107 may also be used to close and lock doors 108,109,110 and to lock elevators 112, 113 in the common area 105 so that the assailant, or the emergency situation, may be prevented from entering, or spreading to, other parts of the building 150 or be contained in a location. For example, if a shooting were to occur in the room 104, the assailant may be locked in that room by closing and locking door 108. If the assailant has already left that room and is in location 111 in the process of seeking other victims in other rooms or in common areas, all three doors 108,109, 110 may be closed and locked in an attempt to contain the assailant until the emergency responders arrive. The elevators 112,113 and the doors 114,115 of the stairwell 116 may be similarly closed and locked if the assailant, or the emergency situation, was in or moving towards those areas.

The second activation mechanism 106, 107 may further be used to open the storage compartment 103 to provide access to the defensive instrument so that the individual can use that instrument to protect himself, herself, or the crowd in an emergency situation. The defensive instrument may simply be a club or bat, instead of the more powerful handgun, stun gun, tear gas, or pepper spray weapons. Also contemplated as a weapon would be other protective instruments such as a fire extinguisher, gas mask, or other instrument used to combat an emergency situation depending on the use of the building and the type of emergency situation that could be encountered.

The building 150 to be protected in a preferred embodiment of the invention is a school or university, but the system can also be used in an office building, movie theater, hospital, or any other public place having rooms or section where people congregate. The room 104 may a classroom or office. The common area 105 may be a hallway, stairwell, elevator, pantry, cafeteria, entrance, entrance, exit, or any area that is available for use by more than one person. In this embodiment, the building 150 is a school, the room 104 is a classroom, the common areas 105 are a hallway, stairwell, and entrance/exit, and the security office 120 includes a principal’s office, school security office, and police station.

The security system 150 may further comprise additional storage compartments 103 with one preferably installed in each room 104 and optionally in the common area 105 so that each room 104 and the common area 105 has a defensive instrument available to counter an emergency if the emergency happens in that room 104 or common area 105. Additional cameras 101 and monitors 102 may also be installed in the common area 105 so that each common area 105 can record, transmit, and receive video and audio of an emergency situation like room 104.

Referring to Fig. 2, one embodiment of the storage compartment for a defensive instrument 103 is illustrated. Figs. 2(a) and 2(b) illustrates the exterior of the storage compartment 103 and Fig. 2(c) illustrates the interior of the storage compartment 103.

In reference to Figs. 2(a) and 2(b), the exterior of the storage compartment 103 on one side may comprise a screen 200, a first activation mechanism 201, a second activation mechanism 202, a camera 203, a handset 204, and a microphone 205. For smoke detection, an ionization and photoelectric sensor 208 is provided. The first and second activation mechanisms 201 and 202 correspond to the at least two activation mechanisms 106,107 in Fig. 1. Figure 2(b) illustrates that the side of the compartment 103 comprises a first door 206, a lock mechanism 207, and a second door 209 to safely store and provide access to the defensive instrument in the storage compartment 103. Safety hinges 210 are provided to make it difficult for an unauthorized person to remove the first door 206.

The screen 200 may display the room number of the room or the name of the common area that is experiencing a non-emergency or emergency situation when the first or second activation mechanisms in a room is activated. The screen 200 may also display such information through a layout of the floor or the building that points to which room or common area is experiencing the non-emergency or emergency situation.

The camera 203 and microphone 205 are provided to also record video and audio of the non-emergency or emergency situation. They may be used to supplement the camera 101 in the same room or in the same common area to record from a different angle since the storage compartment 103 may be placed at a location different from the camera 101. They may be triggered similarly like the camera 101 by the first and second activation mechanisms 201,202 depending on whether the situation is non-emergency or emergency.

When the camera 203 and microphone 205 are triggered in a non-emergency situation by activating the first activation mechanism 201, they, along with the camera 101, record the video and audio of the non-emergency situation. The recorded video and audio are available for later retrieval but are not transmitted to other rooms, common areas, or a security office for viewing. This is because those in other rooms do not necessarily need to know what is happening in that room or to evacuate, and the recording in this situation is mainly for evidence collection to help understand the situation in a subsequent investigation. For example, when an imminent fight is about break out between two students, the teacher may record this event to know who provoked the fight, who threw the first punch, and who assisted in the fight, etc.

On the other hand, when the camera 203 and microphone 205 are triggered in an emergency situation by activating the second activation mechanism 202, they, along with the camera 101, not only record the video and audio of the emergency situation but also transmit the recorded video and audio to other monitors 102 in other rooms and in the common areas and to the security office 120. In this way, those nearby the emergency situation may escape or take the appropriate actions and the security personal can provide aid based on the information transmitted. A multi-angle viewing of a non-emergency and emergency situation help eliminate blind spots and reveal obstructed areas during recording.

The handset 204 provides communication capability to the security office. The communication capability may be accessible after either the first or second activation mechanism 201, 202 is activated. For example, the handset 204 maybe configured to provide communication capability to the principal’s office or school security office after the first activation mechanism 201 is activated and to the police station after the second activation mechanism 202 is activated. The communication capability to the police station may or may not be required to first activate the first activation mechanism 201. The communication capability may also be accessible even when neither the first or second activation mechanism 201,202 is activated. The handset 204 may be configured by default

-8to provide communication capability to the principal’s office or school security office when neither the first or second activation mechanism is activated. The difference between utilizing the handset 204 with the first activation mechanism 201 activated and utilizing the handset 204 without the first activation mechanism activated 201 is that the latter does not provide recording by the camera 101, camera 203, and microphone 205. The handset 204 may also provide communication capability to other rooms 104 and common area 105 without activating neither activation mechanism or with activating one of the activations mechanisms.

Since the first and second activation mechanisms 201,202 are the at least two activation mechanisms 106,107 in Fig. 1, they have all the functions described earlier. In addition, they can activate visual alerts on all the screens 200 of all the storage compartments 103 and sirens, if equipped, on all the storage compartments 103. Each of the activation mechanisms 201,202 can also send an alert to the corresponding security office and notify security personnel the situation. The second activation mechanism 202 may further open the first door 206 to provide access to the lock mechanism 211 that can be unlocked to obtain the defensive instrument. The first and second activation mechanisms 201, 202 maybe buttons, keypads, finger print sensors, smart card sensors, acoustic sensors, or any combination thereof. The lock mechanism 211 may be a keypad, finger print sensor, smart card sensor, or any combination thereof. In this embodiment, the first and second activation mechanisms 201,202 are buttons and the lock mechanism 211 is a keypad. When one or both of the first and second activation mechanisms 201,202 are acoustics sensors, they may detect a gun shot, an explosion, a breaking window, or noise having a certain decibel level or frequency. Since the second activation mechanism 202 is associated with a more serious situation, it may be desired to render the second activation mechanism 202 inoperable until the first activation mechanism 201 is activated. They, however, may also be equally accessible without any restriction.

A shown in Figs. 2(a) and 2(b), the storage compartment includes a smoke detector sensor 208 which is able to detect a smoke situation and when so detected send a fire alarm to inform the building occupants of the need to evacuate. The sensor 208 can also send a message to the local fire department of the smoke or fire situation so that an appropriate response can be made to address the situation. This sensor 208 can be of the type that also detects excessive heat to indicate that a fire situation may be present.

In reference to Fig. 2(c), one embodiment of the interior of the storage compartment 103 is illustrated. The interior may comprise a first section 220 for storing a defensive instrument 221, shown in this figure as a handgun, a second section 212 for storing a magazine 213 or other related peripheral items, and a third section 215 for storing the electronic components of the handset 204. Also provided are sections for storing or accommodating the electronics for the other features of the compartment 103. Section 216 provides storage for the electronics of the sensor 208, section 217 provides storage for the electronics of the camera 203, and section 218 provides storage for the electronics of the microphone 205. Section 219 provides storage for the electronics of the wired or wireless system that communicates with other storage compartments, main computers or outside protection agencies (i.e., police, fire, paramedics, etc.).

The first section 220 is situated with one of its sides adjacent to the door side 214 of the storage compartment 103. The door side 214 is the side that has the first door 206, the lock mechanism 207, and the second door 209. The second section 212 is situated below the first section 220 and with its one of sides also adjacent to the door side 214. These sections have one side adjacent to the door side 214 so that the defensive instrument 221 and magazine 213 can be obtained when the second door 209 is unlocked through the lock mechanism 207. The third section 215 is situated adjacent to the first and second sections 220, 212 and opposite to the door side 214. In another embodiment, the first and second sections 220, 212 may be combined to form one larger section to store a larger defensive instrument. In yet another embodiment, the storage compartment 103 may be large enough to house multiple first and second sections to store multiple defensive instruments and magazines.

Referring now to Fig. 3, the security system 100 may be optionally connected to a main system 300. The main system 300 may include a processor of computer that can change the settings and functions of the security system 100. Examples of such changes include the security offices the first and second activation mechanism should contact, the telephone numbers of the security offices that the handset 204 should dial or that are automatically dialed when the first or second activation mechanism 201,202 is or is not activated, the recording of the cameras 101 and 203, the video and audio transmission by the monitors 102, the inopcration of the second activation mechanism 202 until the first activation mechanism is 201 is activated, the disarmament and armament of the security system ioo when either the first or second activation mechanism 201, 202 is activated, the

-10□ate Reçue/Date Received 2021-02-16 keypad combination, siren override, the text of the visual alerts, the system log of all events, the routine automatic or manual security system 150 check, etc. These changes may be made directly on the main system 300 or through an administration remote 301 when the operator is away from the main system 300. When the security system too is not connected to a main system 300, these changes may be made individually on the cameras 101, the monitors 102, and the storage compartments 103.

Figure 4 illustrates a room or hall monitor 320 which is activated when button 201 or 202 are activated. Monitor 320 is attached to the wall by a bracket 322 and includes a screen 324, a camera 326, a smoke and fire sensor 328, and a microphone 330. When an emergency situation is identified through activation of button 202 in one of the building rooms, the video and audio are transmitted to other monitors in other rooms and to the monitors 320 in the common areas and in the security office 120. The monitors 320 in common areas provide viewing of emergency situation as well as using camera 326 to record or transmit the situations occurring near the monitor. This can be used to monitor movement of unauthorized individuals or even to monitor the evacuation of individuals from the building. Microphone 330 can monitor nearby sounds. Sensor 328 can independently monitor smoke or fire situations and generate an alarm when necessary. In this way, those nearby the emergency situation obtain further information on which way to escape or take the appropriate actions and the security personal can provide aid based on the information transmitted. A multi-angle camera can provide the greatest viewing of the adjacent area but an appropriate selection of monitors can also be used in order to provide the greatest viewing with elimination of blind spots or obstructed areas during viewing or recording. As above, the camera and microphone information can be recorded and stored for future use in recreating the situation or learning how best to respond to similar situations in the future.

While the above is a description of some particular embodiments of the invention, various alternatives, modifications, and equivalents may be used. Therefore, the above description should not be taken as limiting the scope of the invention which is defined by the following claims.
