  • Patent number: 8525664
    Abstract: A system and method are disclosed for communicating heartbeat signals representative of the condition of a security system to a monitoring station. A controller is provided that transmits a heartbeat signal to a monitoring station within a given time period and awaits an acknowledgement signal from the monitoring station. If an acknowledgement signal is received within a time interval from the transmission of the heartbeat signal, then the time period is reset and another heartbeat signal is not sent until the next time period. If an acknowledgement signal is not received by the controller within a few seconds of transmitting the heartbeat signal, then another heartbeat signal is sent from the controller to the monitoring station. Heartbeat signals are only transmitted from the controller if an acknowledgement signal is not received from the monitoring station. In this manner, the amount of data sent over a communication link is reduced.

  • Patent number: 8081070
    Abstract: A mobile security monitoring method and system are provided. An alarm security node communicates with an intelligent security that is activated by a breach in a security zone. This breach starts a video monitoring/recording sequence that is sent out via broadband link to an alarm center. The alarm center forwards this alarm information to a user as SMS/MMS information through a mobile network. The user can view and evaluate what is going on at the security zone and can decide what action to initiate. This minimizes false alarm generation and thus cuts down the costs of following upon false alarm(s) by an alarm security provider. For security and cost reasons, the intelligent security system may be the only client of the server-side alarm center. Existing IT infrastructure at the security zone can be used such as W-LAN, broadband, GPRS, and mobile devices. A mobile phone can be used for activation and deactivation of intelligent security system based on a manual push of a button on the user device.

  • Patent number: 7990260
    Abstract: A normality determination unit determines that a communication function for an outdoor unit of its own is normal when receiving a signal from one of indoor units, and writes a normality flag into an EEPROM. Further, the normality determination unit determines that it is not asserted that the communication function for the outdoor unit of its own is normal when not receiving a signal from any of the indoor units for a predetermined time period, and deletes the normality flag in the EEPROM.

  • Publication number: 20110169629
    Abstract: Embodiments of the present invention relate to a range reduction detection apparatus that is able to detect blocking of its field of view. Detection of an event, due to movement or intrusion within the field of view, is arranged to start a timer, which will time-out thereby providing an indication of such blocking unless a subsequent event is detected within the time-period.

  • Patent number: 7978095
    Abstract: An integrated circuit includes an output pad, an alarm output pad, and a test mode output pad. A first multi-bit register is programmable to store programmable data such as data that identifies a customer for whom the integrated circuit has been manufactured. A second multi-bit register is programmable to store customer specified threshold data. A first circuit selectively couples the first and second multi-bit registers to the output pad. The first circuit is operable responsive to the integrated circuit being placed into a test mode to perform parallel-to-serial conversion of either the customer identification data stored in the first multi-bit register or the customer specified threshold data stored in the second multi-bit register and drive the converted data for output through the output pad. The integrated circuit further includes a tamper detection circuit operable responsive to the customer specified threshold data to generate a tamper alarm signal.

  • Patent number: 7973659
    Abstract: A security system comprises a system control panel for arming and disarming the security system. A door sensing unit comprises a first radio frequency (RF) transceiver interconnected with the system control panel over a network. The first RF transceiver is mounted proximate to a door that defines at least a portion of a perimeter around an area to be monitored by the security system. The first RF transceiver has an RF detection field proximate to the door. A disarm device comprises a second RF transceiver that automatically transmits a disarm device packet. The first RF transceiver receives the disarm device packet when the second RF transceiver is within the RF detection field. The first RF transceiver sends a disarm message to the system control panel over the network to disarm the security system based on at least the disarm device packet.
