A security gate for a retail store shelf having one or more products includes a header and at least one hinge arranged in a horizontal alignment with the header. A rigid frame is connected to the header with the at least one hinge and a guard is positioned across the rigid frame, the guard preventing a user from removing the products. A latching mechanism connects the rigid frame to the header and urges a customer to use two hands to open the security gate.

A security device for protecting objects from theft or unauthorized removal includes a first component configured to be fixed to an object and a second component configured to be removably secured to the first component. The second component includes an alarming mechanism configured to be armed prior to the second component being secured to the first component. The alarming mechanism may include one or more actuating mechanisms that actuate the alarming mechanism. In certain embodiments the second component is configured to slidably engage the first component. In other embodiments, the security device further includes a cable having an end attached to the first component or the second component.

A door lock mechanism is disclosed that includes door lock and alarm features. The mechanism includes a controller and a sensor useful to detect motions that are representative of attempted access through a door to which the door lock mechanism is attached. The controller can set an alarm condition if a measured motion, such as a measured acceleration, meet and/or exceeds a threshold. If an appropriate access control credential is provided through a user device then the alarm condition may not be set by the controller. The door lock mechanism can be coupled to a remote station via a communications link if needed, such as a radio frequency link. The remote station can additionally be in communication with the door lock mechanism via a network. The remote station can be used to send and receive messages regarding door lock mechanism status, configuration, etc.

A porch piracy parcel theft prevention system and method includes a delivery location apparatus configured for adaption to a building to receive a parcel, the delivery location apparatus including a sensor and a parcel locking mechanism. The sensor is configured to detect the presence of a delivered parcel placed into the line of sight of the parcel detecting sensor. When armed, the parcel locking mechanism is configured to trigger an alarm when the parcel detected locking mechanism detects removal of the parcel from the line of sight of the parcel detecting sensor. When disarmed, the package may be removed from the line of sight of the parcel detecting sensor without tripping the alarm. Among other uses, helps prevent parcel theft from single family dwellings.

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.
