A number of different security systems, such as in home or business locations, periodically transmit status data to a remote facility such as a central monitoring station so that it is continuously informed of the security systems' status. The status may relate to an alarm status, armed status, or trouble code status. A user interface at the remote facility provides a spreadsheet format that allows a user to quickly ascertain the status of the security systems, and to send commands to the security systems. The security systems may be controlled individually or in groups, such as to add or delete authorizations. The user interface can filter or sort the information, or obtain further details. Other information, such as video and audio data from a security system, can also be provided to the remote facility for use in the user interface. Information can be recorded for subsequent playback.

A combined alarm and surveillance system integrates an existing alarm system (12) with an existing surveillance system (14) such that functions unique to each system are combined in a complementary manner. The existing alarm and surveillance systems are combined via an interface (16) comprising an array of electric relays (52,54,56,58,60,62). Each relay receives a signal from either the alarm system or the surveillance system and retransmits the signal to the other system in a form that is compatible with the receiving system. The alarm system is configured to communicate alarm status information to the surveillance system, and the surveillance system is configured to communicate control signals to the alarm system, such as an alarm system reset signal.

This invention satisfies a need for surveillance of any fixed or mobile location from a 4G wireless terminal or cellular telephone equipped to view video. The surveillance device consists of digital video cameras, microphones and alarms interfacing a control unit which has the ability to time stamp and store all camera outputs on a storage device, recognize alarms, send alarm status to a remote wireless user, receive wireless calls from the remote user and act on remote commands to transmit any camera output occurring during a time period selected by the remote user. The latter will enable the remote user to document video and sound for a time interval of interest. Video and sound of this time interval may be placed in permanent storage for transfer to a portable video medium. This invention will employ the new 4G wireless network to allow a wireless terminal or telephone equipped with a video display to select the proper bandwidth needed to receive streaming video and sound from the remote surveillance device.

A fire door control system permits user input during regular use and during alarm conditions. The system utilizes primary and secondary power sources and incorporates a variety of preventive safeguards assuring that functionality of the fire door control system will not be lost. The system utilizes primary power when possible in all alarm conditions. However, during alarm conditions when primary power is lost or when a hand crank hoist remains dangerously engaged, the system is bumplessly connected to a secondary power source and a fire door of the system is closed with the aid of a clutch that directly connects the drive input with an axle that supports the fire door. The clutch pulses on and off to control the descent of the door. The system includes an electronic controller for coordinating the operation of elements of the system and for implementing a method of controlling a fire door system.

An alarm system sensor (10) monitoring movement of an object (D) and placing the system into alarm when the object moves more than a predetermined distance from a predetermined position. First and second reed switches (16, 18) are located in a predetermined orientation relative to each other and in tandem to the object. Bias magnets (24, 26) are used with the reed switches. A magnet (20) is movable with the object and produces a force simultaneously sensed by both reed switches. This force maintains both reed switches in a state keeping the alarm system in a non-alarm condition so long as the object substantially remains in its predetermined position. The object, when it moves, moves toward one of the reed switches and away from the other reed switch. Movement of the object more than the predetermined distance results in the force sensed by one of the reed switches increasing and the force sensed by the other reed switch decreasing. Either change in sensed force activates the appropriate reed switch causing the alarm system to go into alarm.

A Radio Frequency Identification (RFID) tag according to one embodiment includes a controller for setting one or more alarm states upon occurrence of one or more alarm conditions, and a visual display device under control of the controller, the visual display device providing a visual, audible, and / or tactile indicator of an alarm condition when an alarm state is set. The visual, audible, and / or tactile indicator of the alarm condition optionally can only be reset by an authorized entity, or cannot be reset.

A cellular alarm notification signal is received wirelessly from an alarming vehicle, and a position of a cellular transceiver of the alarming vehicle is requested and provided to police, security, emergency personnel, and / or surveillance cameras. A vehicle alarm notification is sent directly to the owner of a particular vehicle immediately upon alarm, or to the police, or to building security to dispatch an investigative team, or to a building surveillance company to activate or monitor a relevant security camera. In addition to the alarming status of the vehicle, the cellular alarm notification cellular call may provide a position of the alarming vehicle to the notified party, obtained through appropriate location services provided in a wireless system to satisfy requirements for responding in a personal emergency to a requesting public safety access point (PSAP).
