A access control system includes a catch configured to be affixed to an inner portion of an enclosure, a latch configured to engage the catch when the catch is attached to the enclosure and an access door of the enclosure is in a closed position. The access control system is configured to detect, using one or more sensors, when the latch is within a predetermined proximity of the catch, and responsive to detecting that the latch is not within the predetermined proximity of the catch, determine whether an authorized credential was received via a communication interface to open the latch, and when the authorized credential was received, register an authorized opening of the latch in a memory device, and when the authorized credential was not received, register an the unauthorized opening of the latch in the memory device and enter an alert state.

A system for use in a residential property, the system including a first computing system positionable in the residential property and including a first memory and a first processor. The system also includes a second computing system including a second memory and a second processor, the second computing system in communication with the first computing system over a network. The first memory comprises program instructions executable by the processor of the first computing system to: recognize a sound indicative of an unexpected event; retrieve, from a database stored in the first memory, an acoustic profile of the unexpected event; and responsive to the identifying the unexpected event, transmit a notification including an identity of the acoustic profile of the unexpected event to the second computing system over the network.

A building alarm system and automated door lock arranged to place the alarm system in an armed state when a door lock fails to engage to lock an associated door in a closed position. Activation of a single button by a user or use of specific code by a user to gain access to a building can cause the alarm system to automatically rearm and for door locks at the building to be locked after entry by the user. A first responder code can be used by first responder personnel to gain access to a building after an alarm system indicates an alarm state, e.g., that corresponds to an emergency condition.

Barricade devices and methods of barricading a door are disclosed. Such devices and methods may be used to barricade a door, and thereby prevent an intruder from entering a sheltering space, such as a classroom, storeroom, or hallway. The barricade-device may have a pivotable stop-device that is pivotable from a location adjacent to a door. The pivot-location may be at an elevation that is lower than a door handle on the door. The stop-device may be pivotable from a reserve-position to a stop-position. In the reserve-position, the stop-device does not barricade the door. In the barricade-position, the stop-device barricades the door. Operation of the barricade-device may require the use of one or more major muscle groups of the body, but need not require precise dexterity of the fingers or hands (e.g. such as that required to manipulate small keys, latches, and/or the grasping and turning of assemblies). As such, the barricade-device may be used properly and quickly by a wide range of people having differing physical and mental capabilities.

A sensor system to reliably alert and inform a user of the status of a window, in particular, a sensor system which reliably informs the user if the window is both in a closed position and also that the locking mechanism is in the locked configuration. There are thereby provided two independent sensor systems within the casement window handle assembly which are arranged to verify that the window handle is in the locked configuration and also that the window sash is in the closed position relative to the window frame. The casement window handle assembly comprises a first sensor for indicating the position of the window handle and this comprises a first sensor component mounted to the pivotal/movable handle and a second component fixed within the mounting base.

A door locking device for a smart door apparatus (10) is provided comprising an interior door handle positionable on an interior side of a door; an exterior door handle positionable on an exterior side of the door (14); a lock for the door (14) which is coupled to the interior door handle, the lock having a deadbolt which is activatable by actuation of the interior door handle; a controller for automatically generating an alert signal in the event of activation of the deadbolt; and a wireless communication module associated with the controller, the wireless communication module automatically transmitting the alert signal in the event of activation of the deadbolt.
