A security device is disclosed comprising a main housing, a power supply housing releasable from the main housing and a release arrangement configured to provide a release process in which the power supply housing is moveable from an installed configuration to a released configuration via a partially released configuration. A power connection is provided for supply of power to the security device when the power supply housing is in the partially released configuration. Processing circuitry is configured to obtain power via the power connection and receive an indication that the power supply housing has moved from the installed configuration and/or to the partially released configuration.

A security device for an item of merchandise is provided. The security device includes a non-programmable locking mechanism comprising a mechanical lock and a programmable locking mechanism comprising a monitoring circuit operatively coupled to an alarm. The security device is configured to secure an item of merchandise from theft or removal when the mechanical lock is locked and to be separated from the item of merchandise when the mechanical lock is unlocked. The alarm is configured to provide an alarm signal if the security device is separated from the item of merchandise while the monitoring circuit is armed.

A system for tamper detection of a motion detector. The system includes an electronic controller configured to receive orientation data from an accelerometer of the motion detector. The electronic controller is also configured to filter the orientation data of the accelerometer of the motion detector. The electronic controller is further configured to determine an orientation of the motion detector using the filtered orientation data. The electronic controller is also configured to identify a tamper condition of the motion detector based on the orientation of the motion detector. The electronic controller is further configured to activate an alarm device of the motion detector based on the tamper condition.

Various embodiments provide systems and methods for detecting tampering with a monitoring device using biometric data.

Described is a security sensor comprising two or more sub-sensors for use in a variety of installations where different magnetic fields may be experienced by the security sensor as a result of the variety of installations. One of the sub-sensors may have a low magnetic sensitivity while the other sub-sensor may have a much higher sensitivity to magnetic fields. In operation, one or both sub-sensors are used to determine if a door or a window has been opened.

A security system architecture and method of operation that combines a local security network with control panel and sensors, a central monitoring station (CMS), and a separate operator computer server that provides a web portal for both the homeowner and CMS, that maintains a persistent connection between the control panel and CMS allowing failsafe dual-path signaling. This dual-path signaling technique is extended to provide an effective “smash and grab alarm”, and various approaches to dual-path signal management are disclosed including handshaking, persistent domain monitoring, relayed Operator 3-to-CMS signaling, etc. Improved processes for remotely accessing video are also disclosed along with an improved process for remote control panel configuration, and control panel interfacing with home automation appliances.

A portable alarm system has a base unit including a processor electrically connected to a wireless transceiver configured to communicate wireless signals to an external location. The base unit is further configured to receive wireless alarm signals from at least a first sensor and a second sensor, both of the first and second sensors being physically separated from the base unit. The processor is configured to be selectively programmed by a user to cause the base unit to communicate with a remote monitoring station in response to receiving an alarm signal from the first sensor, but not in response to receiving an alarm signal from the second sensor. Instead, when an alarm signal is received from the second sensor, the processor causes a different action, other than communicating with the monitoring station, to occur. Such action can include, for example, sending a wireless communication to a mobile electronic device.

A smoke detector includes a tamper indicator that can prevent a cover from at least partially covering a battery location and/or mounting of a detector body to a detector mount if a battery is not located at the battery location of the detector body. The detector mount and/or cover can engage with the detector body by relative rotation about an engagement axis, and the tamper indicator can pivot about a pivot axis that is parallel to the engagement axis and/or move along a linear path. The tamper indicator can prevent engagement of a portion of the detector mount, such as an intermediate component between the detector body and a base of the detector mount, with the detector body. The intermediate component can at least partially cover the battery location when engaged with the detector body. The base of the detector mount can engage with the detector body via the intermediate component.

Doorbell systems can include a doorbell and a remote communication device. In some embodiments, the remote communication device can be communicatively coupled to a wireless network of a building, to the doorbell, and to a remote computing device. In several embodiments, the remote communication device facilitates communication with at least one of the doorbell, the remote computing device, and a remote sensor.

A geo-locked field device that is situated in a non-moving position and is operable as long as its position, including altitude and direction, is unchanged. If the position of the device is changed or disturbed, then the device will become inoperable. If the position is returned to its former position after being disturbed and rendered inoperable, then the device will continue to be inoperable. Providing a special signal to the device may cause it to become operable.
