A supplemental door lock comprises a door-mounted component and a floor-mounted component. The door-mounted component includes a door-mounted plate, a hinge plate, and a locking assembly. The door-mounted plate is configured to attach to a door. The hinge plate is mounted on the door-mounted plate and includes upper and lower bridges which form spaces between the plates. The lower bridge includes a groove. The locking assembly includes a hinge pin, a locking blade, and a locking post. The hinge pin is positioned in the spaces and may be rotated between unlocked and locked positions. The locking blade includes a tab attached to the hinge pin and positioned in the groove when the hinge pin is in the locked position. The locking post is attached to the locking blade. The floor-mounted component includes a plate to be mounted on the floor. The plate includes a slot which receives the locking post.

A breach tool for unlocking a supplemental door lock mounted on a lower edge of a first side of a door comprises a handle section, a first hinged section, and a second hinged section. The handle section includes a first panel and a second panel connected to the first panel. The first hinged section includes a first hinge that rotatably joins the first hinged section to the first panel of the handle section and a tab extending outward from the first hinged section at roughly a right angle. The tab is positioned opposite from the first hinge. The second hinged section includes a second hinge that rotatably joins the second hinged section to the first hinged section and an upturned edge positioned opposite the second hinge. The breach tool is configured to be pushed under the door to raise a locking feature to unlock the supplemental door lock.

A door security apparatus includes a door-locking member and a sensor assembly. The door-locking member removably engages a plate. The door-locking member is a barricade that restricts movement of a door from a closed position to an open position while the door-locking member is engaged with the plate The sensor assembly is configured to detect engagement between the door-locking member and the plate.

Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.

An electronic deadbolt lock which includes a housing; an electronic recognition device disposed on the housing; a turnpiece pivotally mounted on the housing and connected to a deadbolt; a key operating mechanism disposed on the housing and connected to the deadbolt, wherein the deadbolt moves as a result of rotation of one of the turnpiece and the key operating mechanism; and a braking mechanism controlled by the electronic recognition device, wherein the braking mechanism normally applies a brake to the turnpiece to prevent the turnpiece from being rotated, and it is only when a user passes verification by the electronic recognition device that the turnpiece can be rotated by the user.

A safe with lock tampering capabilities is provided. A lock apparatus includes a lock body, a lock backplate, a lock, and a sensor. The sensor raises an event when a first end and/or a send end of the sensor loses contact with a surface of the lock body and/or a surface of the lock backplate. The event is reported by the safe as a lock tampering event. Whenever the safe loses power and is subsequently restored power, the safe reports a lock tampering event.

A system and method are described for implementing latched attributes within an IoT system. For example, one embodiment of a method comprises: specifying an attribute for each of a plurality of items of data managed in an Internet of Things (IoT) device and/or an IoT service, at least some of the attributes comprising latched attributes having a current value and an indication of state changes to the latched attribute over a period of time; when an IoT device is unable to connect with the IoT service for a period of time maintaining an indication of any state changes occurring to the latched attribute over the period of time; upon establishing a successful connection between the IoT device and the IoT service after the period of time, transmitting the indication of state changes of the latched attribute from the IoT device to the IoT service; and analyzing the indication of state changes to determine whether to generate an alert condition on the IoT service.
